Wisdom NWB-20 Charger for KL Series Lamps

The NWB-20 is a portable charger specifically designed for Wisdom KL series lamps with LiIon batteries.

The NWB-20 is the recommended charger for the KL4MS, KL5M and KL5MS Wisdom cap lamps.

The charges uses the industry-standard and very robust 'keyway' charging pin, which is inserted into the lamp head and secured with a half turn.

Charging is indicated by a simple LED indicator; red for charging, green for fully charged. The charger correctly conditions the lamp battery and automatically switches off at the end of the charge sequence, preventing over charging and allowing the battery to be topped up safely and at any time.

For the KL8M, KL8MS, KL12M and KL12MS we recommend the faster NWB-25A charger.

AC input only.
