Compatible Sony camera power kit

This kit supplies a 3.7 V 1200 mAh lithium-ion cell and a quadruple USB charger for Sony NP-BK1 or NP-FK1 batteries. It fits Bloggie MHS-CM5, MHS-PM5, Webbie MHS-PM1 and Cyber-shot DSC-S750, S780, S950, S980, W180, W190 and W370 models. Photographers who need spare power for these cameras can charge up to four cells at once.

Sustained multi-cell charging behaviour

The charger accepts 5 V at 2 to 3 A through Micro-USB or Type-C and delivers 4.2 V at 800 mA for one or two cells, dropping to 500 mA each when three or four are loaded. This taper keeps the total draw within the 15 W input limit during extended sessions. Users who need all four cells ready quickly should note the lower per-slot current at full occupancy.

Thermals noise and power draw

The intelligent compact charger shows status and capacity on its display while operating silently with no moving parts. At 3.5 by 2 by 2.5 inch it stays cool under the 15 W maximum input. Builders who require a higher single-cell charge rate or AC mains input will need a different solution.
