Four batteries and triple USB charger

The set includes four lithium-ion NP-BK1 batteries rated at 3.6 V and 1200 mAh each, plus a charger that can replenish three cells simultaneously. It targets owners of compatible Sony Bloggie, Cyber-shot and Webbie models who need spare power for extended shooting sessions.

Suits users with listed Sony cameras.

Photographers using the Sony models named in the compatibility list gain a convenient USB-powered way to keep multiple batteries ready. Buyers whose cameras require a different battery form factor or voltage should look elsewhere, as this pack only fits the specified NP-BK1 and NP-FK1 types.

LCD shows charge status per bay

The intelligent LCD panel reports real-time charging progress and remaining capacity for each of the three slots. The charger accepts 5 V 2 A input via Micro USB and delivers 4.2 V 0.5 A per channel, letting you monitor every battery at a glance.

Questions about this item

Should I buy the 4-pack or a single battery for my Sony Bloggie MHS-PM5?

The 4-pack includes four 1200 mAh batteries and a triple USB charger so you can keep three spares ready and charge them together, which is practical for long shooting days.

What does the 4.32 Wh rating mean for actual recording time on a Cyber-shot DSC-W190?

At 3.6 V and 1200 mAh each battery stores 4.32 Wh; real-world recording time depends on the camera's power draw, screen use and temperature, so expect a few hours of typical mixed shooting per cell.

How does the USB triple charger's 0.5 A output per slot affect charge speed?

Each of the three slots delivers 4.2 V at 0.5 A, so a depleted 1200 mAh cell takes roughly two and a half hours to reach full capacity while the LCD shows progress.
