Four-battery kit for Sony K-type cameras

The pack supplies four 3.7 V 1200 mAh lithium-ion cells and a single quad charger, replacing the need to buy spares and a separate dock for each Bloggie, Webbie or Cyber-shot model that uses the NP-BK1 or NP-FK1 battery.

Quad USB charger with dual-input flexibility

Micro-USB and USB-C ports accept 5 V 2-3 A power sources, while the intelligent display shows real-time capacity and status as the unit feeds 800 mA to one or two cells and 500 mA to three or four simultaneously.

4.32 Wh per cell covers casual daily shooting

Each battery delivers enough energy for typical snapshot sessions on the listed Cyber-shot and Bloggie bodies, but extended video recording or multi-day trips without mains access will exceed the combined capacity of the four cells.

Questions about this item

How often will the NP-BK1 1200mAh lithium-ion batteries need replacing?

Lithium-ion cells typically last several hundred charge cycles; with four 1200mAh packs in rotation you can spread wear and delay replacement.

What limits continuous charging when all four bays are occupied?

The quad charger drops to 500mA per bay with three or four batteries, so total charge time per set is the practical limit.

How much heat or noise does the charger produce during all-day use?

The compact 5V 15W input charger runs silently with no fan; warmth stays low thanks to the 800mA and 500mA output limits.
