Kastar 3-pack D-Li92 batteries + quadruple charger

Three-battery kit with four-slot charger

This pack supplies three lithium-ion cells and a single charger that can replenish up to four batteries at once. It targets photographers who shoot long days with Pentax Optio WG, Olympus Tough or Panasonic HX-WA models and want spare power without carrying multiple wall adapters. Each cell delivers 3.7 volts and 1800 milliampere-hours, matching the original D-Li92 specification. The bundle replaces the need to buy separate chargers for each spare battery.

Quadruple simultaneous charging

The charger accepts Micro-USB or USB Type-C input at 5 volts and up to 3 amps, then distributes 4.2 volts across four independent slots. When one or two batteries are inserted each receives 800 milliamps; with three or four the rate drops to 500 milliamps per slot. An on-board display shows real-time capacity for every bay. Photographers who need all three spares ready by morning can plug the unit in once and walk away.

Swappable plate and bundled Type-C cable

The charger chassis uses interchangeable plates so the same dock can serve other battery families when the plate is swapped. A USB Type-C cable is included in the box, letting the unit draw power from modern laptop ports, power banks or wall bricks without hunting for a legacy Micro-USB lead. Users whose cameras already charge in-body gain no extra speed from this dock, and videographers requiring continuous hot-swap power will find the 500 milliamp multi-slot rate too slow for sustained recording.
