Klarus K2A

3-in-1 Battery Holder, Rapid Charger, & Power Bank

The Klarus K2A is a sleek charging solution for your button top 18650, 20700, and 21700 batteries that gives you a storage space as well as full access to their potential via power bank functionality. If you want to have a pair of specialized batteries on hand to power modern flashlights and devices, why not keep them charged and usable in the meantime?

Charge/Discharge Capability

Dual USB terminals and dual battery bays enable charging or discharging of two high-tech batteries. Simply insert your battery into the adjustable prong system secure beneath a magnetic cover. With batteries, access 18W recharge input via the USB-C port or use it as a rapid charge power bank for your other devices through the USB-A and USB-C connections. Enjoy the peace of mind of PD/QC3.0 certified construction that keeps electronics safe during lightning-fast recharge sessions supplying either the K2A or the rest of your device library.

The K2A has the added benefit of reviving batteries that have been over-discharged down to 0 Volts, where most chargers cannot read the low power level. This allows you to repair dead batteries, restoring full function and vitality to the cells in the process.
