USB-C Input | Two Independent Bays | Fits 21700, 18650, 14500 & More | Cable Included
Two Bays. Charge a Pair at Once. A compact charger for the 3.6V/3.7V lithium-ion batteries that power your rechargeable flashlights, with two independent bays so you can charge two batteries at the same time, or just one. Each spring-loaded contact slides to fit cells from a small 10440 up to a 26650 or 32650, and it charges from any USB power source using the included cable.
Powertac Dual Bay USB-C Charger:
This dual-bay charger keeps your spare batteries ready 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 one or two batteries, and each bay's own indicator light shows it is charging. The bays work independently, and each has a sliding negative contact that adjusts to the length of the battery, so one charger handles 10440, 14500, 16340, 18650, 21700, 26650 and 32650 Li-ion cells. Batteries not included; batteries are sold separately. Only need one bay? See the Powertac Single Bay USB-C Charger.
