Kastar NP-BY1 Quad USB Charger

The Kastar NP-BY1 charger powers up to four compatible lithium-ion batteries simultaneously. It accepts Micro-USB or USB Type-C input and includes a Type-C cable. An intelligent display shows charging status and remaining capacity for each bay. Designed for Sony NP-BY1, Pentax D-LI78, Ricoh DB-80 and Sanyo DB-L70 cells.

For multi-camera shooters and action-cam owners

Ideal for anyone who runs several Sony, Pentax, Ricoh or Sanyo cameras using the listed batteries and wants one dock to recharge them all. Not suited for photographers whose cameras use proprietary packs outside the NP-BY1, D-LI78, DB-80 or DB-L70 families. Buyers needing mains-powered operation without a separate USB power source should look elsewhere.

4.2 V 800 mA per bay (two bays)

The charger delivers 4.2 V at 800 mA when one or two batteries are inserted, dropping to 500 mA per bay with three or four batteries. This current split decides whether the charge speed meets your workflow. Input is rated at 5 V 2–3 A, 15 W maximum.
