Klarus K2 2 Cell Battery Charger

The Klarus K2 USB smart charger is the big brother of the smaller CH1.

In addition to the benefits of the CH1 (being able to charge Li-ion, Ni-MH and Ni-Cd batteries) you’ll also have the added benefit of being able to charge two batteries at once.

This gives you the freedom to charge in bulk, or lets you charge in just half the time if you have a powerful flashlight.

The Klarus K2 also lets you use it as a USB power bank charger for electronics too.

The body of the unit features charge status indicators which allows you to see how much longer your cells will take to charge.
