Is it OK to charge the eroll so often? Won't that reduce the life of the battery?
Actually it's not good for batteries to be fully drained. As for the voltage of cig sized and 808 some 808 are 3.7- 4.2 volts. Many use the eRoll for out and about and a larger PV while @ home. Have to remember also the batteries only cost $9.00 each. There are also mini eGos- 350- 400 mah that can be bought- fires at 3.7 volts, 510 threading and approx 2 1/2" long X 14 mm diameter.
