The image link may not work, but the text should speak for itself, and I'm just wondering if it's even possible. It's one of these viral facebook things and I smelled bullshit straight away. Here's the text with the image:

_______________________________________

I do this all the time! I guess I won't be doing it ANY more !

A few days ago, a person was recharging his mobile phone at home.

Just at that time a call came in and he answered it with the charging Instrument still connected to the outlet.

After a few seconds electricity flowed into the cell phone unrestrained and the young man was thrown to the floor with a heavy thud. As you can see, the phone actually exploded.

His parents rushed to the room only to find him unconscious, with a weak heartbeat and burnt fingers.

He was rushed to the nearby hospital, but was pronounced dead on arrival.

Cell phones are a very useful modern invention.

However, we must be aware that it can also be an instrument of death.

Never use the cell phone while it is hooked to the electrical outlet! If you are charging the cell phone and a call comes in, unplug it from the charger and outlet.
_________________________________________

My reason for it being bullshit is that I figured there must be all sorts of things to prevent something like this happening? Plus the general resistance/smallness of the phone charging wire, fuses that should blow, etc etc. But I know nothing of the finicky things to do with electricity.

I mean sure, it happened to some extent in the photo, but should we all now be scared to use or phones while charging in our presumably quite safely built British homes?

Bullshit
Why would an electrical surge target a phone?

I've seen pics of a sat nav which exploded when the li-ion battery got too hot. Think it is possible?

Complete bullshit. The things that people believe on Facebook make me realise just how retarded a large proportion of my friends aquantiences are. Laughing

@Matray... Li battery exploding... yes. It kiling you? No. It blowing up because you used the phone? No.

I'd be more worried about the microwaves sent out by the phone by your balls than the batter.

No. Mobile phone chargers have fuses, and houses have breakers specifically to prevent a surge from apower outlet into a device like that.

And even when they do fail, Li-on batteries don't explode like that. They overheat, and maybe spontaneously combust, but definitely don't explode.

My opinion: phone started to puff up then jet flames seconds later. Possibly caused by an earlier injury to the battery or maybe just a failure of battery. Ive had a mate that punctured a laptop battery without knowing?!
I learnt this when he phoned to ask "should batteries smoke much?"

This reminds me of a news report I saw a few days ago young boy seriously hurt whilst he was sleeping because believably of his blackberry set fire to his bed that he left on.

Haha you've got to be a right gulable cunt if you actually believe that story.

Even if the battery did explode it has nothing to do with it being plugged in! And although you would be slightly burned it would definitely not kill you.

Looking at it from a slightly different point of view...

"He was rushed to the nearby hospital, but was pronounced dead on arrival.", fortunately there was just enough time to get him to pause for a couple of pictures.

Totally picked up on that too, but couldn't be arsed to go back and edit the original post. Laughing

Can't fucking stand that preachy pointless sort of bullshit that circulates the internet.

100% true. This happened, don't know if the pictures are genuine. They had poorly insulated transformer windings and could land up sending 240VAC directly to the USB plug.

Dodgy chinese micro USB charger. I bought one from Farnell electronics and they did a 100% recall on them because of this. I'd bought one for my Raspberry Pi and i got a phone call off them.

Here's how seriously they took it. I was supposed to package it up and they were going to send a courier out to collect it and refund me the money. SInce it cost all of £2.99, I just threw it in the bin.

It isn't unheard of. Iphones were getting a reputation for popping at one point.

Current doesn't flow un restrained like that.

Things built into the house to prevent things like this.

Breakers
Fuses
The charger wire would have melted before the phone exploded
This is total bullshit.

Typed by someone who has clearly never had a dunt off a ringmain before.


Please never do any mains wiring, you'll get hurt. Based on 2007 statistics, around 30 people die every year in the UK as a result of a low voltage electric shock and 350,000 receive a serious injury.

Breakers don't trip out the instant that their operating current is exceeded - it needs a fairly heft overcurrent to trip them. Fuses are even worse. Breakers and fuses protect the house wiring - not connected appliances. Cables can carry a surprisingly high current for a short enough period to do significant damage.

Take a ring final in a typical house. Breaker or fuse will be rated at 32A and can carry a much higher current before they trip or fail. In the very short term (lightning strike or induced pulse) they can carry thousands of amps. 32A at our domestic voltage of 230v produces a thermal load of 7.3kW into a short circuit.

Aside of the energy that a domestic system can dump into a faulty device, to put your heart into a fatal fibrillation takes a typical current of 35mA on an AC system - how does the 32A breaker protect against that? Modern systems also have RCDs which detect current imbalances and operate quickly to protect against shock but older systems may not have these.

There were a large number of serious burns caused by poorly manufactured batteries when lithium technology was first introduced. Whether this story is true or not, there have been serious injuries.

FWIW on similar lines wasn't it some laptop batteries that would explode. Company had to do a recall and a lot of PR. Think it was DELL but doing a google tells me exploding batteries also in HP and Sony devices.

This story did the rounds in our office some time ago.

It goes with out saying, the first thing I did when I got home that night was make some toast and not bother my arse about it.

Anything is possible, but there are things that aren't very probable; I think this is one of them.

Cant imagine it's relevant - but the charger in the picture above appears to be a Euro / American type plug with no earth pin... don't know if that would make any difference?

*edited because my spelling is worse that a 4 years olds today.

Nope. Chargers are typically double insulated and don't need an earth. UK market ones are only fitted with an earth pin (usually non-conductive) in order to operate the safety shutters in the socket.

I use 4 Euro 2 pin plug's on different devices (bought in Holland & Spain)
I use a screwdriver to open the shutters and plug them in and never had an issue

as to the OP can't see it being true on several issues, one being the cable from the charger to the phone would not take
anything near the type of power needed to do that damage
the wires would burn out almost instantly
or the diodes and other components would fry themself

worst I can see happen is the phone would blow a track at the input or pop a component
