Four-pack LI-50B batteries and quadruple charger

This set supplies four lithium-ion cells plus a single charger that can power all of them simultaneously. It targets photographers who use Olympus Traveller, SP, Stylus, SZ or Tough models, Panasonic HX-WA series cameras or Pentax Optio WG and RZ bodies that accept the LI-50B, VW-VBX090 or D-Li92 battery. The bundle replaces the need to carry multiple single-bay chargers on a shoot.

1800 mAh capacity at 3.7 V

Each cell delivers 6.66 Wh, matching the original LI-50B specification listed for the compatible cameras. The charger outputs 4.2 V at 800 mA for one or two batteries and 500 mA when three or four are inserted, so charge time scales with the number of cells. Buyers who need higher-capacity packs for extended video sessions will not find that option here.

Interchangeable plates and dual USB inputs

The charger ships with swappable plates that adapt to Olympus, Panasonic and Pentax battery shapes, and it accepts power from either a Micro-USB or a USB-C source; a USB-C cable is included. An LCD panel shows individual charging status and remaining capacity for each bay. Users without a USB-C power adapter must supply their own.

Questions about this item

How long will the 1800mAh capacity actually last in my Olympus Stylus 1030SW?

The 1800mAh cells deliver 6.66 Wh each, matching the original LI-50B rating, so shooting time in the Stylus 1030SW is equivalent to a fresh Olympus battery.

What does the USB-C and Micro-USB input with 5V 2-3A 15W actually limit when charging four batteries together?

With four batteries inserted the charger splits current to 500mA per slot, so a full charge cycle takes longer than when only one or two batteries are charged at 800mA each.

Will the 3.5 by 2 by 2.5 inch charger block adjacent outlets on a travel power strip?

The compact 3.5 x 2 x 2.5 inch footprint fits between standard sockets on most strips, leaving neighbouring outlets free for other plugs.
