E-cig charging devices now start one fire each week | Daily Mail Online

"Describing the dangers of incompatible chargers, he said: ‘You plug in an e-cigarette that doesn’t use an awful lot of current into a charger that does and ... the device starts to heat up."

Good article put out by the Daily Mail Online from the UK.  It includes some good graphics on the dangers of E-Cigs when using incompatible chargers.  The lithium batteries on these devices are small, but they pack a serious punch.  As with any Lithium battery, if you use a charger that pushes too much power into the battery, and it is not designed to hand that amount, the battery will heat up.  The heat causes the battery to fail and go into thermal runaway.  Eventually it will vent and possibly combust.

Always use brand name batteries, from reputable sources with the same voltage which the device and charger is designed to use.  Another part of the problem is using cheap knockoff batteries that may or may no have gone through the required testing for safety.
