The K2 battery charger manufactured by KLARUS has two cells capable of charging almost all rechargeable batteries (Li-ion, Ni-MH, Ni-Cd and LiFePO4). The microcomputer control system allows each of the two battery slots to charge individually. It has an LED display that clearly shows the progress of the charge, when all 4 lights are fixed, the charge is complete.

The voltage detection for Ni-MH batteries is done automatically, however for Li-ion and LiFePO4 batteries you will need to select the appropriate voltage by clicking the select button. The output charging current of 0.5A or optional 1A connects directly to a car charger socket, computer USB port or other USB charger socket for charging at home or while traveling.

It is recommended not to exceed 1A of charge, for a 650mAh battery. This charger does not charge the 3400mAh specific batteries for the RS11 and RS20 lamps.


  • DV / dt control technology to fully charge Ni-MH and Ni-Cd batteries.
  • Reverse polarity and short circuit protection.
  • Overcharge protection to prevent damage to the battery.
  • Automatically stops charging when finished.
  • Self-activation function.
  • Automatically reactivates "zero voltage" short circuit protected Li-ion batteries that have been fully discharged.
  • Does not charge a battery that cannot be reactivated.
  • Durable ABS.
  • Optimal heat dissipation design for long life.
