As you seem to indicate, the poster of the video said that it was a genuine
joyetech eGo 650mah battery that exploded.
Interesting, he said that he was charging it on his "USB cable", which leads me to think that he had it plugged into a USB port on his computer. I've heard conflicting thing about doing that, including "the USB puts out 5 amps, which is too high". I just started to type "But wouldn't the battery just draw as many amps as it requires as it's charging", and then thought about my automobile battery chargers that can charge a battery slowly at 2 amps, or more quickly at 10 amps (at 110V I should add).
So - plugging a pass
through into a computer USB port. OK? Bad? Why?
