Three batteries and a four-slot charger

The pack contains three lithium-ion cells rated at 3.7 V and 1200 mAh each, plus a compact charger that can fill four batteries simultaneously. It targets owners of Sony Bloggie, Cyber-shot and Webbie models listed in the compatibility data who want spare power for extended shooting sessions.

4.32 Wh per cell with room for four at once

Each battery stores 4.32 Wh, enough for typical stills and short video clips on the supported cameras. The charger accepts up to four cells, so users can rotate a full set without waiting for a single slot to free up.

5 V input with micro-USB and Type-C

The charger draws up to 15 W from either micro-USB or Type-C ports and delivers 4.2 V at 800 mA for one or two batteries, dropping to 500 mA when three or four are loaded. An onboard display shows charging status and remaining capacity for each slot.

Questions about this item

Will the Kastar NP-BK1 batteries work in my older Sony Cyber-shot DSC-W180 and DSC-W190 models?

Yes, the 1200 mAh 3.7 V NP-BK1 batteries are listed as compatible with the Cyber-shot DSC-W180 and DSC-W190, plus the DSC-S750, DSC-S780, DSC-S950, DSC-S980, DSC-W370, Bloggie MHS-CM5, MHS-PM5 and Webbie MHS-PM1.

How does the quadruple charger show that each battery is charging correctly?

The intelligent compact charger displays charging status and battery capacity for every slot; output is 4.2 V at 800 mA for one or two batteries and 500 mA when three or four are inserted.

What comes in the box and do I need a separate power adapter?

The pack includes one quadruple charger, three NP-BK1 batteries and a Type-C cable; the charger accepts 5 V 2-3 A input via Micro-USB or Type-C, so any 15 W USB power adapter will work.
