One battery and four-slot charger

The Kastar NP-BY1 kit supplies a 1100 mAh lithium-ion cell and a compact charger that can handle four batteries at once. It is aimed at owners of compatible Sony, Pentax, Ricoh or Sanyo cameras who want spare power for long shoots or travel. The charger accepts interchangeable plates so the same unit can serve several battery models.

USB power input and intelligent status display

The charger draws 5 V at 2–3 A (15 W) through either Micro-USB or USB-C and shows charge level and battery capacity on its built-in screen. Output is 4.2 V at 800 mA for one or two cells and 500 mA for three or four cells simultaneously. The 4.07 Wh cell operates at 3.7 V and generates minimal heat during normal charging cycles.

Swappable plates and dual-port flexibility

A Type-C cable is included and the swappable plate system lets you adapt the charger to other supported batteries without buying a new dock. The compact 3.5 by 2 by 2.5 inch footprint fits easily in a camera bag. Photographers needing more than one spare cell or a faster single-bay charger will need a different solution.

Questions about this item

How do I install the NP-BY1 battery and what step is often missed?

Insert the battery into one of the four charger slots, connect the charger via Micro-USB or Type-C to a 5 V 2-3 A source, and select the correct plate for NP-BY1; the step often missed is fitting the proper plate before charging.

What maintenance or replacement will the NP-BY1 battery need later?

The 1100 mAh Li-Ion cell will gradually lose capacity; replace it when run-time drops below your needs, and keep the charger contacts clean for reliable 4.2 V 800 mA or 500 mA output.

What limit appears first during sustained charging of four NP-BY1 batteries?

With four batteries inserted the charger drops to 500 mA per slot, so total charge time increases compared with one or two batteries at 800 mA each.
