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.

Questions about this item

How long will a 1800 mAh D-Li92 battery last in a Pentax Optio WG-3 GPS?

Capacity is 1800 mAh at 3.7 V, giving 6.66 Wh. Actual shooting time varies with GPS use, flash, LCD brightness and temperature, so no single figure applies.

What does the 4.2 V 800 mA output mean when charging four batteries at once?

The charger delivers 500 mA per slot when three or four batteries are inserted, so each cell charges more slowly than the 800 mA single-battery rate.

Will the quadruple charger fit in a camera bag alongside an Optio WG-5 GPS?

The unit measures 3.5 by 2 by 2.5 inches, small enough to sit in most compact camera bags next to the camera body.
