e-Cig Battery Explodes... Discussion?

[Maxcat]

Hi maxcat,

It's all down to the power regulator, a plug socket will give 240v of electric out but the regulator will limit it, an ipad charger won't put 240v into the ipad because it limits this to a 5v input, hence why my iPhone plug won't charge my ipad when in use, only when it's off.

Devices that require higher or lower power have a regulator to monitor this so plugging a lower power device into a high power charger will seriously overcharge the device as mentioned by the manufacturers.

So a charger that outputs 1.2 amps is ok and one that outputs 2.1 amps is not?

Surely any device will draw only as much power as is required, just because a charger can output 2.1 amps it doesn't mean the device will take it.

I get the impression a perfectly good mains to usb device is being blamed rather than the
10 for a $ pos interface device that seems to be involved in most of these incidents.

I agree. My ego batteries (I assume all egos are similar) require an output from the interface device of 4.2 volts. The interface device has an input of 5 volts and an output for charging of 4.2 volts. Even though my interface devices state an output of 4.2 volts, don't overheat and have been reliable I wouldn't leave them unattended.

I'm no electronics expert, but I get the feeling that's it's something to do with over charging. Trying to pack more and more ions into something already full to capacity could cause heat via compression of the ions and heat is not a good thing with batteries,especially unattended ones. Two things going on - one is a battery shouting out "i'm full, i'm full" and the other is the charger getting the message and shouting "OK already, I 'll stop giving you more". A communication error caused by incompatibility or, simply, unserviceable equipment, may result in enough heat to cause the big bang, much the same way as how the universe was created?

The Universe was created by an idiot who didn't read the manual? Cool!

jasox, it is also an idea! "made in china"... could explain much!

Hi marina, and welcome to the site.

In response to both of your statements, Please listen to the more experienced users here on this point, especially KMS,

1) the guy was using an incorrect charger. Apple chargers are only sold for and meant for charging Apple equipment, not e-cigarette batteries. This is highly dangerous and should never be done. This in all likelihood is what caused the explosion as too much power was going into the battery.

2) "The battery was made in China". This should not be an issue. As a new vaper (and even as an experienced vaper), you will find that almost every bit of your vaping equipment is made in China, perhaps even the e-liquid if it is made by Dekang or Hangsen. Most items are made under strict quality controls and if you buy from a vape store where they specialise in vaping equipment and know about what they are selling, you should have nothing to worry about.

As a newbie, it's recommended you read the forums, ask questions if you need help or have concerns about your equipment and find out as much as you can about vaping.

Whilst this article has been in newspapers and media sources around the world, their business is to find exciting stories which will sell their papers or make them popular. The need for accuracy and actual useful information is often forgotten, especially by papers like the Daily Mail which in the UK has built its reputation on sensationalism and scare stories.

Be fore this turns into WAR, every one look at their e-cig charger. Somewhere on it, it will tell you the input and output. (if it does not bin it). That little lead that has the usb connector and connects to your ego type battery, will have the input rate for as safe as can be use. Venturing above that stated input, will at some point cause a problem of some magnitude.
Now the one that blew in the bar.
Firstly the ipad charger puts out 4 times the max input for the ecig cable/connector. So straight away your stressing the cable (if not the battery as well)
So with the cable now receiving 4 times the max input, damage is being done to the internals, that lower the input to the output. When enough damage is done, (it's states he uses it regularly) and the internals are fried, it will stop working properly, or cease to function, or even catch fire. In this case it seems to now not function properly, allowing the current to rise and cook off the battery.
Now look at a proper e-cig wall plug. The output will match the input for the usb cable. (5v 500mA).
As for differing household appliances, they all have different needs as well. That's why we use fused plugs, 3amp, 5amp, etc. Not to limit the amperage to the appliance, but as added safety, incase the internals mess up.

Having said all that twoddle. A bar full of assorted liquids, would not be my first choice place, for leaving an e-cig to charge. Even with the correct charger.

Ok just to get this clear in my head. Ego chargers are 5v input and 4.2v 420mA output. All my USB wall plugs are 5v but range from 1amp up to 2.1amp output. What is a safe maximum ampage output or is it the output voltage that is the problem?

Has anybody got a link to a proper e-cig wall plug charger?

A device will only take the amps required, the problems are more likely as stated in the following link.

Google has pages and pages of results for the input "mobile phone explodes" ,none of which will ever reach the glorious pages of the Daily Mail.
