Klarus K2 Smart Charger

A very compact two-cell charger that can charge most rechargeable batteries used in e.g. flashlights and headlamps. You can also use it as a power bank with a Li-ion battery as the power source. Optional charging current selection: 0.5A or 1A. The LED display shows the charging progress, and charging stops automatically when complete. So the charger won’t kill your batteries like the old ones used to do. The micro USB charging cable connects directly to a car charger plug, a computer USB port, or other USB charger plug for charging at home or while traveling.
