There are several factors to consider when choosing the best charger for your vape batteries. Not least of which is the size batteries you use. A charger that can accurately, safely, and promptly charge various sized batteries is what vapers are looking for. But many 18650 chargers don’t take 20700 and 21700 batteries, which are larger and of a higher capacity than 18650. Since those 20-sized batteries are appearing more and more in vapes now, older chargers likely won’t fit those cells. Now you can find that charger that will fit your batteries here in the best battery chargers of 2018.
