Three-pack with triple charger

The set includes three Kastar NP-BX1 lithium-ion batteries and a single charger that powers all of them at once. Each cell delivers 3.7 V and 1240 mAh for 4.6 Wh of capacity. The bundle targets photographers and videographers who use compatible Sony Cyber-shot, RX or Action Cam models and want spare power without buying batteries individually.

USB-powered charger frees wall outlets

The charger draws 5 V 2 A from any USB wall adapter, car charger or computer port via the supplied micro-USB cable. It outputs 4.2 V at 0.5 A per slot so three batteries charge simultaneously. This arrangement removes the need for multiple AC adapters and lets you top up cells while travelling or working from a laptop.

LCD readout shows steady charge progress

An integrated LCD panel reports real-time status and remaining capacity for each bay. The 0.5 A per channel rate keeps current low and consistent, so cells fill gradually rather than in a rapid burst. This gentle profile helps maintain long-term health during repeated cycles.

Questions about this item

How long will the 1240mAh batteries last during continuous shooting?

Does the charger get hot or noisy when all three bays run at 0.5A each?
