Four-pack with smart charger

This set supplies four Kastar BL-5B lithium-ion cells and a matching smart LCD charger. Each cell delivers 3.7 volts and 890 milliampere-hours for 4.26 watt-hours of capacity. The bundle suits owners of compatible compact cameras, mini keyboards and portable radios who want spare power on hand. Buyers needing a different form factor or higher capacity should look elsewhere.

Foldable plug and LED status

The charger accepts AC 100 to 240 volts at 50 to 60 hertz and outputs DC 4.2 volts at 600 milliamps. Its foldable flat pins store neatly in a bag or glove compartment. A red LED shows charging while green indicates standby or full charge. Users who require a car-adapter cable or multi-bay dock will not find those features here.

Check device model before ordering

Verify that your device uses the BL-5B cell; the list includes Yashica EZ Digital NV-1, Vivitar ViviCam models, Rollei Sportsline 60, Tecsun X3 and A5 players, Avantree 10BS, 10BP and CK-11, plus several SVP and mini-keyboard units. The charger operates on mains voltage only. Shoppers whose equipment takes a different battery code or needs USB-C charging must choose another solution.
