Sold out
The Efest Soda Charger features dual battery bays, over-voltage and over-discharge protection, auto cut-off voltage, multi-type battery support, and reliable design. It's reliable design will ensure quick and consistent charging of all supported types of batteries. Charge two batteries independently while simultaneously monitor both batteries. Select between rapid charge mode if you are short on time or use normal charge mode. The sliders for the battery work smoothly and can accept batteries from 30mm to 71mm

The charger can handle 70 mm long batteries including flat top cells. Because the 0.5A current is more like 0.6A, the charger is not that good for non-IMR 16340 or 10440 batteries. Only use IMR 16340 or 10440 with this charger.
Note: Using to high charge current will not make the batteries explode, but will reduce lifetime of the batteries.
