Ready-to-use power kit

This Kastar kit supplies a 3.7 V 890 mAh lithium-ion cell rated at 4.26 Wh together with a compact wall charger. Photographers and owners of compatible compact cameras, mini keyboards and portable radios receive a direct replacement for the original BL-5B pack. The foldable flat plug lets the charger slip into a bag without snagging.

Cool silent charging

The charger accepts 100 to 240 V AC at 50 or 60 Hz and delivers 4.2 V at 600 mA, so the cell replenishes without audible fan noise or noticeable heat. A red LED shows active charging while a green LED signals standby or full charge, giving clear visual feedback at a glance.

Fits existing gear

The bundle works with the listed Yashica, Vivitar, Rollei, Praktica, SVP, Tecsun, Avantree and Topblue devices as well as the VJIANGER and Saneen 4K cameras and several 2.4 GHz mini keyboards. No extra cables or adapters are required, freeing a USB port on the camera or computer for data transfer.

Questions about this item

How do I install the BL-5B battery and charger correctly?

Insert the 890 mAh lithium-ion BL-5B battery into the charger with the correct polarity, then plug the foldable flat-pin charger into any 100-240 V AC outlet. The red LED shows charging; green means full or standby.

What maintenance will the BL-5B battery need over time?

The 3.7 V 890 mAh lithium-ion cell gradually loses capacity. Recharge it at least every few months when not in use, avoid deep discharge, and replace the battery once run-time drops noticeably.

What limit appears first during extended charging sessions?

The charger delivers 600 mA at 4.2 V, so the 4.26 Wh battery reaches full charge in roughly two hours; the charge-current limit is the first constraint under sustained use.
