Compatible battery and charger kit

This Kastar kit pairs a 1800 mAh lithium-ion cell with a quadruple USB charger that accepts interchangeable plates. It fits Olympus LI-50B, Panasonic VW-VBX090 and Pentax D-Li92 batteries used in numerous rugged and travel compacts. Photographers who carry several spare packs can replenish them from one compact unit. The bundle suits owners of listed Olympus, Panasonic and Pentax models needing a single replacement power source.

Sustained charging behaviour

The charger delivers 4.2 V at 800 mA when one or two batteries are inserted, dropping to 500 mA per slot with three or four cells. This taper limits heat during extended sessions but lengthens the total cycle when all bays are full. The intelligent display shows individual capacity so users can track progress without guesswork. Continuous operation at the lower rate remains stable for the duration of a full charge.

USB input limits

Power enters through either Micro-USB or USB-C at 5 V, 2 to 3 A, capped at 15 W. The supplied Type-C cable works with standard USB-A or USB-C sources but cannot exceed the brick's 15 W ceiling. Builders who want faster top-ups for four cells simultaneously will find the rate fixed by this input budget. No higher-voltage PD profiles or proprietary fast-charge modes are supported.

Questions about this item

Does the quad USB charger get hot or make noise when charging four batteries all day?

The charger runs from a 5 V 2‑3 A USB source and delivers 4.2 V at 800 mA for one or two cells, 500 mA for three or four, so heat and fan noise stay low during extended use.

What power source must I already have to run the charger?

You need any USB power supply that can provide 5 V at 2‑3 A (15 W) — a phone charger, power bank or laptop port with a Micro‑USB or USB‑C cable will work.

Will the included 1800 mAh Li‑Ion battery work in my older Pentax Optio WG‑30?

Yes, the battery replaces the Pentax D‑Li92 and is listed as compatible with the Optio WG‑30, WG‑40, WG‑50, WG‑60 and WG‑70 models.
