For charging ego batteries, manual, automatic, 420mAh, 4.2 volts
There are two USB line chargers one for ego batteries and another for 510 batteries, the line charger is the part that creates the right amount of power to recharge the e-cig batteries when the wall plug chargers are the same for both, so any wall charger will work with both types of batteries but the important part is to get the right USB line charger. The result in trying to charge an ego battery on a 510 line charger will be a very slow rate of charge and if using an ego line charger for a 510 then it’s too fast and powerful and it will degrade the 510 batteries very fast and make a very short lifespan.
Screw the dedicated Power supply in the optional USB charger cable. Insert the USB charger cable into the USB port of your computer, USB Home Charger, USB car charger. Do not charge Power supply outdoors or in a damp environment.
