Batteries not included.
It has 6 bays so you can charge tons of batteries at a time, and you can charge them fast with up to a 2A charging rate (selectable). An LCD screen will give you basic status or you can pair the charger to your phone (Android or iOS) to get updates while you're away from it!
It's compatible with most 3.7V Lithium Ion or Li-Mn batteries such as 10440, 14500, 14650, 18500, 17670, 18650, 18700, 26500, 26650* (see note regarding Aspire/IJoy), 20700*, 21700*etc.
It can also charge 15270 or 14250 batteries if you use spacers.
Battery Specific Notes:
*Note that due to the width of 26650s, this can only charge 3 of them at a time. Also, we do not recommend this charger for the Aspire or IJoy 26650s, as their narrow tops don't fit very securely and could easily come loose!
