Three batteries and a four-bay USB charger

This Kastar kit includes three NP-BK1 lithium-ion cells and a compact charger that powers up to four batteries at once. Each cell delivers 3.7 V and 1200 mAh, rated at 4.32 Wh. The charger accepts Micro-USB or USB-C input at 5 V up to 3 A and shows charge level on its built-in display.

The pack fits cameras such as the Bloggie MHS-CM5, MHS-PM5, Cyber-shot DSC-S750, S780, S950, S980, W180, W190, W370 and Webbie MHS-PM1. It also replaces the Sony BC-CSK charger. Photographers using other battery formats or needing AC mains charging should look elsewhere.

Charger supplies 4.2 V at up to 800 mA per slot

When one or two batteries are inserted the charger provides 800 mA each; with three or four it drops to 500 mA per bay. This output profile determines how quickly depleted cells reach full charge.

Questions about this item

What input standard does the quadruple charger use and what output does it deliver per slot?

The charger accepts 5 V 2–3 A via Micro-USB or Type-C and supplies 4.2 V at 800 mA for one or two batteries, dropping to 500 mA when three or four are charging.

What are the physical dimensions of the charger unit?

The charger measures 3.5 by 2 by 2.5 inches, so it fits on a desk or in a small gear bag.

How do you start charging and what common step is missed?

Connect the included Type-C cable to a 5 V 2–3 A power source, insert up to four batteries, and ensure the charger’s display shows each slot’s status; forgetting to use a sufficiently rated adapter is the typical oversight.
