Wisdom NWB-20 smart charger for Wisdom KL5M miners cap lamp


The recommended charger for the Wisdom KL5M lamp, the NWB-20 is a fully portable intelligent single lamp charger specifically tailored to the Li-ion battery of the Wisdom KL5M lamp. It supersedes the earlier NWB-15 portable cap lamp charger.

It is also fully compatible with, and provides a more rugged charger (should it be required) for the KL4MS cap lamp.Charging is through the lamp headset – insert the keyway on the charger into the back of the headset and give a half-turn clockwise (ensuring a good connection) to start charging the lamp. The NWB-20 charger uses constant-current up to ~70% charge (charge indicator LED is red), then switches to constant voltage charging until lamp is fully charged (charge indicator LED is green). The charger then powers-off. This prevents over charging and allows the battery to be topped up at any time.

This charger is also fully compatible with the KL8M, and all KLMS series lamps.
