Seems a chap was injured when the electronic cigarette he was charging
exploded. He was on oxygen, and the oxygen pipe or whatever got damaged
making things far worse. Seems he may also have been using a charger which
wasn't supplied with the cigarette kit.

An 'expert' (think he may have been from the fire service) on the R4 PM
prog explained that USB chargers are not all the same and could give a
much higher voltage than the correct one for the device. So advised
against charging such things from a computer USB socket, etc. He sort of
admitted he wasn't an expert though. He didn't need to.


I thought he did OK, and gave good general advice without commenting
too much about the individual case which the Coroner Court has yet to
give a verdict. He didn't mention the O2.

Follow the manufactures instructions, use the supplied charger and
don't leave unattended.



If they should ONLY be used with the supplied charger then they shouldn't
be using the USB standard interface. The problem is the cigs surely, not
the chargers?
