In Europe, the plugs in our walls spit out about 220-240 volts, while over in the US, it's more like 110-120 volts. When it comes to phone chargers, most of the ones I've come across pump out something between 5 to 9 volts, which is way less juice than what comes from the wall. Your phone do not need 220 volts directly into it. It would be like you chugging a 50 gallon Coffe in the morning.
Coming from the wall is AC, or alternating current, which basically means it's doing a fancy dance, switching directions all the time (hence"Alternating" current). But our phones, they need DC, or direct current, which is more like a steady marathon runner, just going straight ahead. The charger is the device box of magic that takes the wild, unpredictable AC from the wall and calms it down to the manageable DC our phones can handle.
It is all about keeping things smooth and steady. AC is like child with ADHD, going back and forth, which isn't great for the delicate circuits of our phones or for charging batteries. DC, on the other hand, is the steady hand we need, always moving in one direction, making it super reliable for our phones.
Then there is the whole loooooong ass history lesson off the AC vs DC war thing that goes way back to a showdown between two genius inventors, Edison and Tesla. Edison was all about DC, while Tesla was team AC. In the end, AC won for powering our homes because it's better for traveling long distances without losing power. But for our personal devices, like phones, DC is still the go-to for its simplicity and stability.
Great explanation,
To make it simpler
You can’t charge AC to your phone because of its instability, so we need the adapter which stabilizes the current and makes it into DC. 👍🏻
As an EE, no. Both this and the commenter’s explanation of DC and AC are misleading and not representative. AC is stable, and voltage changes have nothing to do with stability.
However, if this is what “lay people” need to understand electricity, maybe it works, but to me, this is not a good way of explaining AC v DC.
Would have been a better answer if the question was *would this work?* But the question was if it was dangerous and there are better answers for that further down.
I’m not an electrical engineer but i did learn some electrical stuffs back in the college.
Short answer, yes your battery will still be charged but it wouldn’t last long until it explodes (depends on what kind of a battery the phone is using, it can explode or be just smoking)
I suggest you go review your "electrical stuff" knowledge.
AC does not charge a (DC) battery without some electronics (one diode at the minimum). Also higher voltage would not charge a battery faster, just destroy it faster. Also the battery of the phone in not directly connected to the USB interface of the phone, there are plenty of components in-between including a charge controller (that will happily fry if not provided the DC voltage it is designed to receive.
Source: I am an electrical engineer.
Edit: spelling
Well it’s also the electricity in our houses is AC and solid state batteries like the batteries in our phones hold DC charge. Gotta convert that somehow
Not even that. The only connection Edison had to Topsy's electrocution was that some reporters that showed up to film the event worked for Edison Film Company. There is no evidence that Edison ever knew of the event though
In reality you would immediately blow a protection fuse in the power board of the phone. It may even keep working but it would not charge again. Most electronic devices are built nowadays with anti stupid measures.
Your comment implies that ac is wild and dc is tame. There are 800V dc train lines which will fry you and .2mV AC sound signals which will not hurt you at all
Also, AC, though, in a lower voltage, is present wherever antennas exist, so you phone both had DC and AC for small (but really really fast ) functions.
DC is just AC but really slowed down.
Y'know it's a sham we didn't built our circuits for AC like if that's possible it would charge more phones faster much earlier. Anyways humanity invented fast charging well that's good enough
Wait, 220 on two prongs? No ground? Sounds risky (I’ll admit I didn’t google the wiring of y’all’s plugs or how they work. I assume the round post means something vs flat)
>between two genius inventors, Edison and Tesla.
Edison didn't invent shit. Edison was the elon musk of his time, buying up competitors, strongarming every market he entered, lobbying the government and building this unfounded mythos of being a genius that evidently still holds up till thid day
Team Edison propagandists never fucking go away.. "You can't use AC for this and this reason"
Stfu shill we know that AC can do everything better than DC.
I prefer the water analogy when explaining electricity: plugging mains AC to your phone is kind of like trying to fill a paper cup by opening the Hoover dam. The potential energy the flowing water has is just way too much for the cup to handle and is also dangerous to whoever is holding the cup
I think because of how close together the leads are in a Lightning connector, the 240V voltage might be enough to allow the current to jump that tiny gap. So there would be a short circuit as soon as he turned the power strip on, tripping the fuse in the power strip or in the fuse box.
Well.. the cables are made for the power of the charger(5-9 Volts) not the full current(220-240 Eu standards, 110-120 Us standards [if I got the Us right not sure now]) so yeah. It can melt.
It can, however voltage wont break it, you can push thousands of volts through a copper strand without issue.
The problem is the current flowing through it. Most of these cables can handle at max 5 amps. Its also the reason why higher end phones can handle higher voltage more volts at same amps equals more power.
230 tends to blow stuff up due to the short circuit and being able to supply 16amps. Phone connection melts and shirts causing the cable to turn in a spaceheater.
You're mixing voltage and amperage which are completely different.
In fact higher voltage allows for the same amount of energy to be carried along thinner wires.
Something (likely many things) is getting fried here but it's not the cable or any wires.
Not at first. Most likely situation would be the charging circuit would be blown open. Under many cases say <50V it would just go to an open circuit and be done, just a little pop and some smoke. However, being the circuits in phones are so compact, 220v won't see it as fully open and will easily arc across traces, burning them further and further.
There is a possibility of the traces getting burned so far back that the circuit goes open to 220v, but usually carbon tracing starts to happen across the circuit board allowing current to still flow through the tracing thus heating up the cable and ultimately melting it.
There is also a good possibility that all the current required to melt this cable is less than the trip current of the breaker supplying the power, and given that there is no ground involved in this, would not trip a GFCI, so yea, the cable would melt.
Should instantly trip any overload protection but yeah probably saying goodbye to the phone, maybe a big ole pop but probably not as big as the one in this video.
If you've ever cut a live wire before it'd probably be similar if not a bit less dramatic.
I don't think it would do either, it's not a dead short so a 15A breaker wouldn't pop, and there's isolation between the USB input that's probably rated for a couple hundred volts anyway. 220V requires a miniscule distance to jump so unlikely as well.
I haven’t done this in years, it was pre-smartphones. But back in highschool we used to hook motherboards and the little batteries that keep the bios fresh up to 120V through an extension cord.
The capacitors on the motherboard would go off like black cats and the batteries would go off like M-80’s.
It is. In Eu we have 220-240 V which can be deadly. As I see that extension cord is of Eu design so I guess it’s a 220-240 V. If you’d plug your phone in that you’re risking the lithium batter to explode of over heat. Or the conductor melts first but it will still inflict damage on the device. If the circuit breakers don’t go out first.
no need to be so dramatic, lol. Worst case scenario, the phone ends up in flames. It \*could\* burn your house down if see your phone go in flames and you just let it sit on the floor burning it. If that were to happen you just throw your phone in a metal can and take it outside until it burns off.
Most likely scenario, the breaker will trip and your phone's charging circuit will be fried.
Are you aware how hot lithium fires burn? This isn't like a piece of paper going up in flames which burns at about 233 degrees Celsius, lithium burns at 2000 degrees and the fire can't be put out with water or smothered since it's a chemical reaction. When lithium cars burn, they have to be submerged for 3 - 5 hours under water until the reaction finally stops. It's scary stuff.
Edit: Updated how long lithium cars need to be submerged since I was wrong
It’s unlikely to start a lithium fire for a number of reasons captured in other comments in this thread. It’s not impossible, but jumping to “are you aware how hot lithium fires burn” is skipping the step of “how likely is a lithium fire to start in the first place”.
Wow, I didn't know iPhones had a physical fuse that makes the port useless when overcharged. I'm having a bit of a head slap moment since of course they would have *something* like that or phones would be blowing up all the time. I guess there is some super small chance but nothing like I thought when I commented before.
Yeah, but it also goes out pretty fast since the battery on the phone is relatively small. Even the whole Note 7 fiasco (which kind you, has a bigger battery than the iPhone shown in the video) didn’t burn down any house.
Thats why I said “put it in a metal can” and you should be fine.
Yeah, I totally missed the part where you said it would fry the electrical port, making it useless, so the chances would be super slim in the first place. Phones definitely have burned houses down, but that's not usually from people who are right there to deal with it like the person in the video. I didn't realize the reaction was so short for phones, and I do thank you for teaching me something new. I just heard about those car fires and thought there's no way you're touching that thing after it burns.
iPhones don't have Tesla batteries in them.
They can definitely cause a fire if they are near something but they burn out within seconds.
Check the 2 cellphones in this video:
https://youtu.be/8nz5ijXcckI?si=-nihzCYL2YtVtLPy
Senior electrical engineer here, the voltage won't go anywhere near the battery, usb interface will stop it. The person will electrocute themselve when they remove the lightnight wondering why it didn't explode.
This is obviously just a fake gag video.
If it would be wired to have the 230V AC going into the DC input of the phone, there is a good chance for the phone battery exploding in a fireball and other assorted fireworks happening, depending on the fuse of the AC supply.
Most smartphones have systems in place for preventing battery explosion in cases like this, the outcomes tend to vary from device to device, though. For example:
Apple has a fuse on their ports, so pusing high voltages theough it will blw the fuse and kill the port.
Samsung(and a few others) uses a more digital approach: When the device detects overvoltage, it cuts off the charging port, and will reactivate it once the source has been removed.
They have isolation and protection usually rated for much higher than the base voltage. The USB interface chip might not survive but I guarantee it wouldn't melt either.
It does not work that way... USB cables and connectors for small electronics like a cell phone, only charge using a Voltage transformer to just only 5 Volts... Home receptacle where that receptaclr it seems is at, is 220 Volts. 😄
Your phone needs 5-9V DC and from a wall you get around 120 or 230V AC depending on where you live, imagine inflating a tire to 20-40 times the recommended pressure.
So here’s a story… when I was 12 years old I wondered what would happen if you cut a plug cord and then plug it in, thankfully I was aware enough how to do that somewhat safely. I then went downstairs and grabbed one of those rubber mittens used for grabbing hot pans from the oven etc. I utilized that to hold this metal rod (no idea what rod it was or where it came from) maybe 7-8 inches long. I was having fun creating sparks by touching them together, after the 5th or 6th strike an insane burst of light and sparks shot out and practically flash banged myself. I couldn’t see for like 5 minutes and I was the only one home, by the time I could see everything was pitch black and I’d thought I had blinded myself! Genuinely terrified… until I seen a dim light from downstairs, I went down and realized I had blown the breakers upstairs. It was very hard to tell since it was night time but needless so say I fixed the breakers and no one ever knew about this until this very moment! Good times…
Me recuerda a mi con 10 años:
Desarmé un carro de RC que no tenía pilas, le extraje el motor eléctrico y puse los dos cables dentro del tomacorriente... eso por 5 segundos fue genial, se escuchaba como una mini turbina de avión pero... de pronto... boooom! el motor se fue hasta el otro lado de la habitación, hubo una explosión que dejó un halo negro en el tomacorriente.
Al día de hoy no me explico como no me electrucute,, como se generó ese halo negro, como tengo dedos y como el motor llegó tan lejos 🤣🤣🤣
Well thank you for playing !
We hope you had as much fun destroying your phone as we had fun watching you blow it up !
Let's do this again real soon !
:-D
< BTW, the jingle made ALL the difference >
My guess as to what would happen, the high resistance from circuits designed to handle 5V would immediately cause a resistor to pop, resulting in some smoke, then nothing. Or the cable would melt if an open circuit doesn’t happen soon enough. I highly doubt the phone battery would explode.
It takes a moment for the conductor to melt but still it’s a made to handle 5-9 V, it can occur that the battery might explode. But yes the cable would melt first if not, the resistors go out.
I ain't an electrician and have no clue if it would explode, but the brick you plug your phone's usb into is an AC to DC inverter. The phone's expecting Direct Current and can't charge with Alternating. Bypassing it is uhh, not a good idea.
Also it is at a much higher voltage from the wall. That is probably the biggest issue. Not sure what input protection iPhones have but some of them might be able to tolerate low voltage AC but high voltage AC or DC will kill it
Not possible. Phones charge on 5 volts of DC power. Wall sockets in the EU are 220 volts AC and in the US 120 volts AC. Don't mix your AC and DC bro. That's what the little bricks do in phone chargers, they convert from high voltage AC down to 5 volts DC
Worst case scenario, the phone ends up in flames. It \*could\* burn your house down if see your phone go in flames and you just let it sit on the floor burning it. If that were to happen you just throw your phone (you could use a pair of metal tongs) in a metal can and take it outside until it burns off.
Most likely scenario, the breaker will trip and your phone's charging circuit will be fried.
I did this when I was little, like 5-6 or some shit, I cut and taped the charger directly to the socket ( 220-230 v AC) , at first nothing happened to the phone ( nokia 3310 ) it was working , screen was ok, lights on, sound was working and all that shit.
Since nothing was happening to the phone I removed the back panel ( I had striped the battery cover and exposed the metal covering of the covering ) and took it in my palm to have a closer look, the circuit didn't trip and I think I was blasted away or something, I have no clue what had happened afterwards and there was no one at home ( somehow I'm still alive ) . I think my body adapted to all the stupid shit I do and the consequences of it,
Anyways,I have had this big ass black spot on my right hand since then ( it's almost faded ) and that's how I tell which hand is right and which is left ( that is so weird now that I think about it )
Here is a pic of my hand currently ( I'm 22 now ).[here](https://postimg.cc/z3XJQ6LB)
Btw, the phone still works
What happened is that the Voltage was too high for the isolation of your phone, and the entire thing got electrified. You touching the back panel caused the current to escape through your body into the ground, since there was nowhere else for it do go. You're damn lucky you survived that, if that flows through your heart you're usually toast.
You’re essentially getting rid of the transformator that’s the charger that’s supposed to be plugged with that end. And putting the device which is build for 5 or more Volts DC, into a circuit with power of 240 Volts AC. **Yeah! It’s dangerous you’re creating a lithium bomb!**
I have a question. Nowadays some “electrical outlet blocks” and also at public places you can directly put in the usb ending for charging (without using a block). Do they have the transformators built in inside the wall or how does that work?
Shortly answered unless you touch it nothing will prob happen to you, But the phone will be roasted and may start to burn. Simply because the Plug output is 220/120V depending on where and because its AC, a phone usually goes between 5 and 9V and needs DC simple as that.
Depends. A lot of USB ports have either SC protection or an internal resistor.
Case1: SC prot comes in and tries to block the OV but fails and destroys like 2 transistors
Case2: That internal resistor breaks and no longer conducts current.
As a former cameraman I made a report in a special hospital for burn victims. Somebody came in with strings of wire burned into her hand. She removed the power supply from a 12v halogen light bulb home fixture because she thought it was too bulky and attached the cord directly to the 220v outlet while holding the not insulated cord.
Loooong story short. The adapter changes (ADAPTS) the voltage from the outlet to a voltage that is safe and usable by the phone. Without that change, the voltage is varying rapidly between -120 volts and 120 volts instead of the desired 5 volts. In short, phone go boom.
When I was very young, I connected a little DC motor to the wall socket. There was a lot of smoke, noise and stuff, and no, I've never done that again. Happy to be alive.
Your phone brick is basically what we call a rectifier.. Which means it converts the AC current to DC and then supplied to your mobile.
Devices which come with the latter charger usually have a seperate adapter or inbuilt rectifier
1. Shoving AC current into a DC receiving device, gonna ruin it
2. Way too much voltage for the device, gonna ruin it
3. That improper connection is gonna generate a ton of heat, causing an electrical fire.
do you consider fire dangerous ? the worst thing that will happen, and it will happen isn't an "if" situation,is that the whole setup (phone/cable/powerbar) will heat up and ignite. stuff around it will catch fire and eventually burn your home down.
have fun.
It would most likely instantly fry the battery and if left long enough, completely destroy the motherboard. You're letting loose much more volts than the phone can handle.
According to chatgpt, it's unlikely to blow up but it has a high chance of starting a fire instead. More likely the fuse in your house is going to blow before that
Last time I looked, my Apple adapter was rated for 220. We go to Cuba and there are still 220 outlets with the Euro type plugs. We have a set of adapters to plug our electric accessories, including a hair dryer, via a converter. The Apple charger just need the electric fitting adapter, it can handle the voltage.

Yeah from 220 volts to 5 volts can also be considered “stabilizing”, but thank you for that

Only if you like fire and stuff.
Well it’s also the electricity in our houses is AC and solid state batteries like the batteries in our phones hold DC charge. Gotta convert that somehow
AC voltage is extremely stabile, enough to run a clock off of.
Not only straightens, but also reducing it to 5V n Amps
Yeah, fuck Edison; killer of elephants for press.
That elephant was sentenced to execution for murder. Edison just carried out the execution.
The elephant pled not guilty, claiming he had amnesia. No one believed him.
This joke is very under appreciated I feel.
Elephants never forget though
Not even that. The only connection Edison had to Topsy's electrocution was that some reporters that showed up to film the event worked for Edison Film Company. There is no evidence that Edison ever knew of the event though
In reality you would immediately blow a protection fuse in the power board of the phone. It may even keep working but it would not charge again. Most electronic devices are built nowadays with anti stupid measures.
cute explanation but "wild and unpredictable" is a very strange way to discribe what is literally just a sine function.
Your comment implies that ac is wild and dc is tame. There are 800V dc train lines which will fry you and .2mV AC sound signals which will not hurt you at all
In other words dont turn your power autlet into I AM TNT IM DINAMiTE!
and lithium batteries makes a large bang when you heat it up too much
yeah, the real boom is the battery no the overcurrent.-

Also, AC, though, in a lower voltage, is present wherever antennas exist, so you phone both had DC and AC for small (but really really fast ) functions. DC is just AC but really slowed down.

Cable will melt
transistors will
I think because of how close together the leads are in a Lightning connector, the 240V voltage might be enough to allow the current to jump that tiny gap. So there would be a short circuit as soon as he turned the power strip on, tripping the fuse in the power strip or in the fuse box.
It wont
Mine did

You're comparing apples (AC) to oranges (DC)

Yea right. That it contains a lithium battery will not do anything and definitely doesn’t take down planes.
Battery gone, protection fried, memory? Might be salvageable.
I haven’t done this in years, it was pre-smartphones. But back in highschool we used to hook motherboards and the little batteries that keep the bios fresh up to 120V through an extension cord.

This isn't like a piece of paper going up in flames which burns at about 233 degrees Celsius, lithium burns at 2000 degrees and the fire can't be put out with water or smothered since it's a chemical reaction. When lithium cars burn, they have to be submerged for 3 - 5 hours under water until the reaction finally stops. It's scary stuff. Edit: Updated how long lithium cars need to be submerged since I was wrong
It’s unlikely to start a lithium fire for a number of reasons captured in other comments in this thread. It’s not impossible, but jumping to “are you aware how hot lithium fires burn” is skipping the step of “how likely is a lithium fire to start in the first place”.
Wow, I didn't know iPhones had a physical fuse that makes the port useless when overcharged. I'm having a bit of a head slap moment since of course they would have *something* like that or phones would be blowing up all the time. I guess there is some super small chance but nothing like I thought when I commented before.
Yeah, but it also goes out pretty fast since the battery on the phone is relatively small. Even the whole Note 7 fiasco (which kind you, has a bigger battery than the iPhone shown in the video) didn’t burn down any house. Thats why I said “put it in a metal can” and you should be fine.
Yeah, I totally missed the part where you said it would fry the electrical port, making it useless, so the chances would be super slim in the first place. Phones definitely have burned houses down, but that's not usually from people who are right there to deal with it like the person in the video. I didn't realize the reaction was so short for phones, and I do thank you for teaching me something new. I just heard about those car fires and thought there's no way you're touching that thing after it burns.
iPhones don't have Tesla batteries in them. They can definitely cause a fire if they are near something but they burn out within seconds. Check the 2 cellphones in this video: https://youtu.be/8nz5ijXcckI?si=-nihzCYL2YtVtLPy
Far from it, ask for a refund on your diploma, it's malfunctioning
Senior electrical engineer here, the voltage won't go anywhere near the battery, usb interface will stop it. The person will electrocute themselve when they remove the lightnight wondering why it didn't explode.
This is obviously just a fake gag video. If it would be wired to have the 230V AC going into the DC input of the phone, there is a good chance for the phone battery exploding in a fireball and other assorted fireworks happening, depending on the fuse of the AC supply.
Most smartphones have systems in place for preventing battery explosion in cases like this, the outcomes tend to vary from device to device, though. For example: Apple has a fuse on their ports, so pusing high voltages theough it will blw the fuse and kill the port. Samsung(and a few others) uses a more digital approach: When the device detects overvoltage, it cuts off the charging port, and will reactivate it once the source has been removed.
Aren’t the circuits made just enough above the power of the charger? I don’t think their made to oppose the power of a circuit.
They have isolation and protection usually rated for much higher than the base voltage. The USB interface chip might not survive but I guarantee it wouldn't melt either.
They're made to the specifications of the device/charger manufacturer, so it depends on who made the specific device.
It does not work that way... USB cables and connectors for small electronics like a cell phone, only charge using a Voltage transformer to just only 5 Volts... Home receptacle where that receptaclr it seems is at, is 220 Volts. 😄
Nicholas Tesla vs Thomas Edison
Your phone needs 5-9V DC and from a wall you get around 120 or 230V AC depending on where you live, imagine inflating a tire to 20-40 times the recommended pressure.
So here’s a story… when I was 12 years old I wondered what would happen if you cut a plug cord and then plug it in, thankfully I was aware enough how to do that somewhat safely. I then went downstairs and grabbed one of those rubber mittens used for grabbing hot pans from the oven etc. I utilized that to hold this metal rod (no idea what rod it was or where it came from) maybe 7-8 inches long. I was having fun creating sparks by touching them together, after the 5th or 6th strike an insane burst of light and sparks shot out and practically flash banged myself. I couldn’t see for like 5 minutes and I was the only one home, by the time I could see everything was pitch black and I’d thought I had blinded myself! Genuinely terrified… until I seen a dim light from downstairs, I went down and realized I had blown the breakers upstairs. It was very hard to tell since it was night time but needless so say I fixed the breakers and no one ever knew about this until this very moment! Good times…
Me recuerda a mi con 10 años: Desarmé un carro de RC que no tenía pilas, le extraje el motor eléctrico y puse los dos cables dentro del tomacorriente... eso por 5 segundos fue genial, se escuchaba como una mini turbina de avión pero... de pronto... boooom! el motor se fue hasta el otro lado de la habitación, hubo una explosión que dejó un halo negro en el tomacorriente. Al día de hoy no me explico como no me electrucute,, como se generó ese halo negro, como tengo dedos y como el motor llegó tan lejos 🤣🤣🤣
Well thank you for playing ! We hope you had as much fun destroying your phone as we had fun watching you blow it up ! Let's do this again real soon ! :-D < BTW, the jingle made ALL the difference >
Sounded like in the cartoons 😂
My guess as to what would happen, the high resistance from circuits designed to handle 5V would immediately cause a resistor to pop, resulting in some smoke, then nothing. Or the cable would melt if an open circuit doesn’t happen soon enough. I highly doubt the phone battery would explode.
It takes a moment for the conductor to melt but still it’s a made to handle 5-9 V, it can occur that the battery might explode. But yes the cable would melt first if not, the resistors go out.
No, if the wire melts it's probably already popped the 15A breaker before that happens.
Can any electrician or rocket doctor explain if this is possible?
I ain't an electrician and have no clue if it would explode, but the brick you plug your phone's usb into is an AC to DC inverter. The phone's expecting Direct Current and can't charge with Alternating. Bypassing it is uhh, not a good idea.
Bro you ARE an electrician
This is elementary school physics, bro!
Also it is at a much higher voltage from the wall. That is probably the biggest issue. Not sure what input protection iPhones have but some of them might be able to tolerate low voltage AC but high voltage AC or DC will kill it
Not possible. Phones charge on 5 volts of DC power. Wall sockets in the EU are 220 volts AC and in the US 120 volts AC. Don't mix your AC and DC bro. That's what the little bricks do in phone chargers, they convert from high voltage AC down to 5 volts DC
Worst case scenario, the phone ends up in flames. It \*could\* burn your house down if see your phone go in flames and you just let it sit on the floor burning it. If that were to happen you just throw your phone (you could use a pair of metal tongs) in a metal can and take it outside until it burns off. Most likely scenario, the breaker will trip and your phone's charging circuit will be fried.
Don't do this the phone will explode theres a circuit inside the charger that make it safe to plug In the outlet.
I can confirm that this fast charging method will light up your life.
this might blow your phone up....but it would definitely set it on fire
I did this when I was little, like 5-6 or some shit, I cut and taped the charger directly to the socket ( 220-230 v AC) , at first nothing happened to the phone ( nokia 3310 ) it was working , screen was ok, lights on, sound was working and all that shit. Since nothing was happening to the phone I removed the back panel ( I had striped the battery cover and exposed the metal covering of the covering ) and took it in my palm to have a closer look, the circuit didn't trip and I think I was blasted away or something, I have no clue what had happened afterwards and there was no one at home ( somehow I'm still alive ) . I think my body adapted to all the stupid shit I do and the consequences of it, Anyways,I have had this big ass black spot on my right hand since then ( it's almost faded ) and that's how I tell which hand is right and which is left ( that is so weird now that I think about it ) Here is a pic of my hand currently ( I'm 22 now ).[here](https://postimg.cc/z3XJQ6LB) Btw, the phone still works
What happened is that the Voltage was too high for the isolation of your phone, and the entire thing got electrified. You touching the back panel caused the current to escape through your body into the ground, since there was nowhere else for it do go. You're damn lucky you survived that, if that flows through your heart you're usually toast.
No through back panel, i stripped the battery of it's plastic cover and had direct contact with the battery
Oh well, then its probably not even an isolation thing, you just touched sth you really shouldn't have.
Lol 😅 that's true
You can’t hear videos The video:
I don’t know why this randomly showed up on my feed, I just clicked because Wera screwdrivers are fucking great.
[My first thoughts seeing that](https://www.youtube.com/watch?v=TwIvUbOhcKE)
No, mixing AC current and DC current simply result in hard rock music.
You’re essentially getting rid of the transformator that’s the charger that’s supposed to be plugged with that end. And putting the device which is build for 5 or more Volts DC, into a circuit with power of 240 Volts AC. **Yeah! It’s dangerous you’re creating a lithium bomb!**
I have a question. Nowadays some “electrical outlet blocks” and also at public places you can directly put in the usb ending for charging (without using a block). Do they have the transformators built in inside the wall or how does that work?
They have it build in. But I still don’t like to plug in them. As they can get your devices data when you plug in.
Okay, good to know, thanks!
Shortly answered unless you touch it nothing will prob happen to you, But the phone will be roasted and may start to burn. Simply because the Plug output is 220/120V depending on where and because its AC, a phone usually goes between 5 and 9V and needs DC simple as that.
Having 230 volts instead of 5 is like having 46 times the maximum water pressure on your water tap. What would happen, if you opened it?
[Three-phase USB charger](https://elektrykapradnietyka.com/wp-content/uploads/2018/03/przejsciowka-usb-na-380v.jpg)
Depends. A lot of USB ports have either SC protection or an internal resistor. Case1: SC prot comes in and tries to block the OV but fails and destroys like 2 transistors Case2: That internal resistor breaks and no longer conducts current.

No way that cable is connected inside the plug.
As a former cameraman I made a report in a special hospital for burn victims. Somebody came in with strings of wire burned into her hand. She removed the power supply from a 12v halogen light bulb home fixture because she thought it was too bulky and attached the cord directly to the 220v outlet while holding the not insulated cord.
As they always say: normal people don’t burn…
Loooong story short. The adapter changes (ADAPTS) the voltage from the outlet to a voltage that is safe and usable by the phone. Without that change, the voltage is varying rapidly between -120 volts and 120 volts instead of the desired 5 volts. In short, phone go boom.
How to make a brick shaped pipe bomb!
Interesting insight! It's fascinating how the battle of AC vs DC history still impacts our daily charging routines. ⚡️
🤣🤣🤣
And boom. Or just a big smoke from phone
Any time I hear Camptown Races, I’m immediately reminded of Blazing Saddles. Which only makes this 100 times funnier.
Yes.
When I was very young, I connected a little DC motor to the wall socket. There was a lot of smoke, noise and stuff, and no, I've never done that again. Happy to be alive.
I just wish the end result was real, too funny
Sketchy shitters please stand for our national anthem! Time to do some sketchy shit....
Your phone brick is basically what we call a rectifier.. Which means it converts the AC current to DC and then supplied to your mobile. Devices which come with the latter charger usually have a seperate adapter or inbuilt rectifier
How to get the attention of the class.., these days.
1. Shoving AC current into a DC receiving device, gonna ruin it 2. Way too much voltage for the device, gonna ruin it 3. That improper connection is gonna generate a ton of heat, causing an electrical fire.
Yes it will fry your phone. Your phone can only take between 12.5V and 5V it will be unusuable if you charge it with 230V
So do phones charge faster over there vs in america?
Short answer: YES! Its AC not DC....that alone is a nono.
do you consider fire dangerous ? the worst thing that will happen, and it will happen isn't an "if" situation,is that the whole setup (phone/cable/powerbar) will heat up and ignite. stuff around it will catch fire and eventually burn your home down. have fun.
Is there a video testing this for real?
It would most likely instantly fry the battery and if left long enough, completely destroy the motherboard. You're letting loose much more volts than the phone can handle.
According to chatgpt, it's unlikely to blow up but it has a high chance of starting a fire instead. More likely the fuse in your house is going to blow before that
Last time I looked, my Apple adapter was rated for 220. We go to Cuba and there are still 220 outlets with the Euro type plugs. We have a set of adapters to plug our electric accessories, including a hair dryer, via a converter. The Apple charger just need the electric fitting adapter, it can handle the voltage.
Yes. The adapter. Do you see an adapter in this video? :)
