Quadruple USB charger for Sony NP-BK1

The Kastar unit charges up to four NP-BK1 or NP-FK1 batteries simultaneously. It suits photographers who carry several Sony Bloggie, Cyber-shot or Webbie cameras and want a single dock to keep every pack ready. Swappable plates let the same charger handle other Sony K-type cells when needed.

Thermals noise and power draw

Input accepts 5 V at 2–3 A for a maximum of 15 W through either Micro-USB or USB-C. Output delivers 4.2 V at 800 mA for one or two batteries and 500 mA each for three or four. The compact 3.5 by 2 by 2.5 inch enclosure runs silently with no fan.

Bundled accessories and software impact

A USB-C cable is included so the charger works straight from a laptop, power bank or wall adapter without extra purchases. An intelligent display shows real-time charging status and remaining capacity for every slot, removing guesswork during multi-battery top-ups.

Questions about this item

How do I connect the Kastar NP-BK1 charger to power and what is the common mistake?

Plug a 5 V 2–3 A source into the Micro-USB or USB-C port using the supplied Type-C cable; the step users miss is providing at least 15 W so all four slots can run at full current.

What part of the Kastar NP-BK1 charger will need replacement first?

The USB-C cable and the Micro-USB / USB-C input ports wear from repeated insertion; the charger body has no user-serviceable parts and no battery is included.

At what point does the Kastar NP-BK1 charger reduce current during a long session?

When three or four NP-BK1 cells are charging together the output drops to 500 mA per slot, so sustained multi-bay charging is the first limit you hit.
