Dear all

One of our electricians had a call relating to an exploded socket outlet.  However the problem was a Power Adapter Model A33 from ebay.  Details are:

Model number A33

Made in CXhina. i

Input 100-240V 50/60Hz. 0.16A

CE is the letter N within a O.  There is a V within another O to the right when viewed from the pins.

There is a number between the L and N pins = 825858-11

Output 6V=1A

Thanks Bob,

if you go onto this link then there is a quiz about spotting fake chargers. I work within residential settings and use this as part of training.

Thanks Invictus

Just checked the three chargers we have here. Using the guide, all seem to be real. But have to say the printed text on all three is so faint that we can't read any of them!

I once purchased an Ipod from Ebay and while charging for the first time it exploded on the table.  No damage except to the device.

No haggle return with full money back.

It appears to me that a lot of the stories in the press of fires caused by 'fake' chargers are actually problems with the device's battery.  This is still a bad event, but misinformation does not help with getting the right messages out there.  Does anyone have reliable information on this?

Regarding the iFake quiz.  It is a bit stupid that you cannot see the explanation if fake/real and the photo at the same time.  You can swap between the two, but having them side-by-side would be much better for learning, which surely was the most important aspect.  This is not really relevant to this discussion, but a useful detail if you are ever setting up a quick like this.

With the exception of one or two problems with specific battery models, I think it's much more likley to be the charger at fault.  Lithium chemistry batteries are very fussy about charge and discharge parameters.  The problems arise when a charger does something the battery can't tolerate.

I think you could in principle get problems with batteries - you could have fake cells that don't accommodate the charging current they say they will, but there's a relatively small market for them.  When was the last time you came across someone using dodgy lithium cells bought off ebay without any certification?  How much more often do you come across dodgy chargers bought off ebay without any certification? 

The modern trend to non-replaceable batteries in tech makes it less and less likely that a substandard battery will be present.  So while in theory either side could be at fault (the charger could pump out too much current or the battery could fail to accept the right current) my guess would be that there are a lot more chargers at fault than batteries.

(Actually, for what it's worth, I have used dodgy lithium cells bought off ebay without any certification, but only with a decently intelligent charger monitoring temperatures, and the first few charge cycles done with the cells in a metal box on a concrete slab well away from anything flammable.  Mine were fine.)

Thanks for your explanation.  Does this mean that the dodgy charger causes the battery to overheat/explode?  That would mean that the headlines about chargers causing fires being correct, and explain why the photos show the fire damage of the device/battery.

There has been recent warnings from fire services about charging smart phones under the pillow at night. Not sure it they overheat due to no ventilation but there are pictures of fire damage to 100% of the bedroom.

In this cold spell at least it will keep your head warm.

Please note that I do not in anyway condone charging your phone under your pillow.

That's the scenario that most concerns me about dodgy chargers.  Of course, they still have all the potential harm of anything substandard plugged into the mains.  I think there's several things that can go wrong - the charger might elecrocute you, the charger might itself catch fire, or the charger might abuse the batteries.  I don't especially distinguish between them, since all three risks are dealt with by having a decent charger, but the exploding battery case is the one that looks most alarming to me - I think it's the case that has most potential to happen suddenly and violently without warning.
