Battery and charger kit for Sony compact cameras

The Kastar NP-BK1 bundle includes one 1200mAh lithium-ion battery rated at 3.6V and 4.32Wh plus a triple USB charger that powers up to three cells simultaneously. It suits owners of compatible Sony Bloggie, Cyber-shot and Webbie models who need spare power for daily shooting.

LCD charger manages three batteries under

Each output delivers 4.2V at 0.5A while the input accepts 5V 2A 10W from a wall adapter, car charger or computer USB port. The intelligent LCD panel shows real-time charging status and remaining capacity for every slot during extended sessions.

USB power limits the charging speed and cable reach

The micro USB cable supplied ties the charger to standard 5V sources so peak current stays at 0.5A per bay regardless of how many batteries are inserted. Users needing faster top-ups or mains-only operation will find the fixed USB interface restrictive.
