Dual charger for Brother scanner batteries

The Kastar FNP120 is a dual USB charger designed for Brother LD0665001 and AP-1908 Li-ion batteries used in DS820W and DS920DW wireless document scanners. It charges two batteries simultaneously and swaps plates to fit different packs. An intelligent LCD shows real-time charging status and capacity for each slot.

Replaces single-bay or proprietary docks

This unit upgrades from chargers that handle only one battery at a time or require a fixed cradle. The jump is worth it when you run two scanners in a busy office or need a spare ready for field work. Input is 5 V at 2–3 A for 15 W total; each bay delivers 4.2 V at 800 mA so both cells finish together.

Check battery model and USB power source

Verify your scanner uses the LD0665001 or AP-1908 pack before ordering; other Brother cells will not fit the included plates. You need a USB power adapter or port that can supply at least 2 A at 5 V — standard 1 A phone chargers will slow the charge or trip the protection circuit. The box includes a Micro-USB cable; Type-C input is also available on the charger.
