And another exploding ecig

[Abyss]

I bet that's not even a genuine apple charger. Looks like the stuff you get for 99p off eBay.

I know someone who used to buy those, cheap, fake apple chargers. Two of them blew up but thankfully nothing serious.

Pretty sure it can.
Check it's power requirements first and see if your USB plug is up to the task.

Thanks.

OK thanks mate. So the problems are not really with the plugs? It is with the part that screws onto the ego battery? Yes its output is 4.2V 420mA.

Yep that's right Abyss, The wall wart is just a supply - as long as it can supply enough power to the charger module then it will be fine. Just to make sure everyone else understands this I will try clarify things.
Battery chargers come in different types, The integrated all in one wall charger that plugs directly into the socket and has a single purpose made output lead or cradle, Cell chargers Like the Nitecore and Xtar - designed to charge individual batteries either singly or in multiple bays, Industrial / Professional - Car chargers etc, and charging modules designed to be used with a multi-purpose power supply and a particular product (Such as an eGo).

The ones everyone argues about are the Charging modules. They are designed to take a multipurpose power supply - and this is where the vast majority make the mistake, they read the little label and see 5v/500mA. They then assume that this is what is output from the device - it isnt! 5v/500mA is it's rated capacity, the MAXIMUM NORMAL VOLTAGE OR CURRENT it can supply. During use the actual current demanded from the power supply may vary from almost 0 to 500mA.

It is the charger module that is important! it limits the voltage 4.2v and current taken from the supply to 420mA. By placing the charging module between the power supply and the battery you regulate the flow of power from the power supply to the battery so that the battery never recieves more than 4.2v @ 420mA. Using the wrong charging module or worse still one of the tiny USB plug type connectors some people supply with cig-a-likes could allow your battery to receive the wrong voltage - and it's voltage that Li Ion cells are sensitive to - not current...

yeah dude, i expect it has a little board in it connected between the usb port and the battery that works like an ego charger. kind of like the usb charging board for the DNA boards.

Yep built in charging circuit...

Here is a photo of the incident released by West Midlands Fire Service -

Never 'mix n match' this very smart person has obviously purchased an ego kit (probably from a market store) and then screwed it into her E-Lites charging device and then in turn plugged that into her iPhone charger.

Here is what the mensa champion Keeley Cooper had to say -
"I’ll never buy another e-cigarette and have no intention of returning to normal cigarettes.

THIS IS WHY E-CIGS EXPLODE!
All I can say is "Muppet Alert!!"

I got it in the end. Thanks.

So those tiny, leadless USB plugs aren't regulated in any way?
Damn

No room for doubt there!
What's amazing is that the industry allowed these to exist at all, without thinking people would try to mix and match.
After all, that's the whole point with USB devices.

Just for information:

I build my own battery boxes with lipo cells.
To charge them, I bought 5 USB charge boards from focal e-cig.
The first box I put together works flawlessly.
The 2nd box went on charge at 5pm, the little light was still red 7 hours later and I noticed the box was getting warm so took it off charge and checked the output voltage from the box mod.
It was 4.12 volts so I changed the USB board and then checked what happened when I plugged it back into the PC. The lights instantly changed from red to green.
The dodgy USB board has now earned itself a one way ticket to landfill.
If the battery had been left unattended and instead of being a 4000 mah pack been a cigalike, the battery might well have vented.

This tale demonstrates that any circuitry can work as intended for anything from hours to years, but with lipo/li-ion batteries, they should never ever be left unattended or overnight unless somewhere they can do no harm if they vent.
