Quadruple USB charger for Pentax D-LI78 batteries

The Kastar NP-BY1 charges up to four compatible lithium-ion packs simultaneously. It accepts Pentax D-LI78, Sony NP-BY1, Ricoh DB-80 and Sanyo DB-L70 cells used in Optio L50, M50, M60, S1, V20, W60 and W80 cameras. Photographers carrying several spares can top them all from one unit. It does not suit owners of cameras that use proprietary battery shapes not listed here.

Sustained charging at 500 mA per slot when four

Input is 5 V at 2 to 3 A with a 15 W limit. Output delivers 4.2 V at 800 mA for one or two batteries, dropping to 500 mA each when three or four are inserted. The intelligent display shows individual charging status and remaining capacity. Build-up of heat during extended multi-bay sessions is managed by the compact circuitry without active cooling.

Interchangeable plates

Swappable plates let the same chassis handle different battery form factors. Power enters through either a Micro-USB or a USB Type-C port, and a Type-C cable is included. The 3.5 by 2 by 2.5 inch footprint sits flat on a desk or packs into a gear bag. Users needing simultaneous AC wall power without a separate adapter must provide their own 5 V source.

Questions about this item

How much heat or noise does the Kastar NP-BY1 produce when charging four Pentax D-LI78 batteries continuously?

The charger runs silently with no fan; its 15 W input and 4.2 V output keep temperatures low during extended use.

Which power source do I already need to run the Kastar NP-BY1 quad charger?

You need any USB power adapter that can supply 5 V at 2–3 A, plus the included Type-C cable or a Micro-USB cable.

Will the Kastar NP-BY1 charge the original Pentax D-LI78 cells from my Optio W60 alongside newer spares?

Yes, the interchangeable plates accept both original D-LI78 batteries and compatible replacements, charging up to four at once.
