What you get in the box

This kit contains one quadruple USB charger and three lithium-ion batteries rated at 1800 mAh and 3.7 V. It is built for photographers who need spare power for long shoots with compatible Olympus, Panasonic or Pentax cameras.

Charging limits of the USB charger

The charger accepts 5 V input through Micro-USB or Type-C and can charge up to four batteries simultaneously. Output current drops from 800 mA per slot with one or two batteries to 500 mA per slot when three or four are inserted, so full charges take longer with a full load.

The capacity that decides if this is the right part

Each battery stores 6.66 Wh, matching the LI-50B, VW-VBX090 and D-Li92 specifications used by the listed Tough, Stylus, SZ, VR, VH, VG, XZ, HX-WA and Optio models. If your camera requires a different watt-hour rating, this pack will not fit.

Questions about this item

Should I choose the 3-pack or a single battery for my TG-850?

The 3-pack gives you three 1800mAh LI-50B batteries plus the quadruple charger, so you can keep two spares ready while one is in the camera.

What does the 1800mAh rating mean when I am shooting with a TG-870?

At 3.7V the cell stores 6.66Wh, enough for several hundred shots or a full day of mixed stills and video on a TG-870 before you need to swap.

How fast does the USB-C charger fill four LI-50B cells?

The charger delivers 800mA to one or two batteries and 500mA to three or four, so a full set takes roughly three to four hours from a 5V 2-3A source.
