Wisdom NWB-30 Fast Smart Charger for Wisdom Cordless Lamps

The NWB-30 is a portable, smart (intelligent) charger specifically designed for Wisdom Cordless 3 / 4 series lamps with LiIon batteries.

It provides a more convenient charging option over the standard USB cable or power pack. The charger also features mounting holes on the rear, allowing it to be mounted on a wall or a board - ideal for outdoor activity centres or show caves and mines where multiple lamps are used and charged at the same time.

To charge, simply insert the Cordless lamp into the charger. 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.


Please note, this charger is suitable for Wisdom brand lamps only. This charger must not be used with any other brand of miners lamp even if they physically fit onto the charger. If in any doubt please contact us before purchasing.
