My point being is that some misinformed people often claim that an internal battery is more safe than external batteries for novice vapers. Wrong. No battery is "safe.

When offered a choice, charge your external batteries with a separate Li-ion battery charger. The USB is primarily for updating the firmware; the USB charger should only be used for occassional use.
