Powertac Single Bay USB-C Li-ion Battery Charger (21700/18650 & More)

One Bay. Most Common Li-ion Sizes. A compact, no-fuss charger for the 3.6V/3.7V lithium-ion batteries that power your rechargeable flashlights. The spring-loaded contact slides to fit cells from a small 10440 up to a 21700 or 26650, and it charges from any USB power source using the included cable.

Powertac Single Bay USB-C Charger:

This single-bay charger keeps a spare battery topped up at your desk, workbench or nightstand. Plug the included USB-A to USB-C cable into a USB wall adapter, computer or power bank, drop in a battery, and the indicator light shows it is charging. The sliding negative contact adjusts to the length of the battery, so one charger handles 21700, 26650, 18650, 18500, 18350, 17670, 16340 and 10440 Li-ion cells. The black textured housing has vent slots and a small footprint. Battery not included; batteries are sold separately. Need to charge two at once? See the Powertac Dual Bay USB-C Charger.
