Kastar LI-50B VW-VBX090 kit

The Kastar LI-50B VW-VBX090 kit supplies two 1800mAh lithium-ion batteries and a quadruple charger for compatible Olympus, Panasonic and Pentax cameras. It suits photographers who need spare power for extended shooting sessions with models such as the Tough TG-610, HX-WA20 or Optio WG-1.

Quadruple USB charger limits

The charger accepts 5V 2-3A input via Micro-USB or Type-C and can charge four batteries simultaneously. Output drops to 500mA per slot when three or four cells are inserted, so full cycles take longer than when charging one or two batteries at 800mA each.

6.66 Wh capacity and headroom

Each 3.7V 6.66 Wh cell delivers enough energy for several hundred shots on cameras like the SP-810UZ or VR-370. Heavy video use or continuous flash on power-hungry models such as the XZ-10 will drain the pack faster, requiring a swap to the second battery or a recharge break.

Questions about this item

Should I buy the twin-battery pack or look for a four-battery option?

This listing only includes two 1800 mAh batteries, but the charger can hold four at once, so you can add two more later.

What does the 6.66 Wh rating mean for actual shooting time?

At 3.7 V and 1800 mAh each battery stores 6.66 Wh, giving roughly one full charge cycle per cell in compatible Olympus, Panasonic or Pentax cameras.

How fast does the USB-C or Micro-USB input charge four batteries together?

With a 5 V 2–3 A supply the charger delivers 500 mA to each of four slots simultaneously, so all four reach 4.2 V in about the same time as two at 800 mA.
