Quad USB charger for Olympus and Panasonic cameras

This kit pairs one 3.7 V lithium-ion battery with a compact charger that accepts four cells at once. It targets photographers who use Olympus Tough, XZ, SP, SZ, Stylus, VR, VG or VH models and want a single dock for multiple spares. The bundle suits travel or studio workflows where several batteries rotate through a day of shooting.

Charges four Li-50B type cells simultaneously

The charger delivers 4.2 V at 800 mA for one or two batteries and 500 mA when three or four are inserted. Micro-USB and USB-C inputs accept a 5 V 2–3 A source, and the included Type-C cable connects to common power adapters or power banks. An on-board display shows charge status and remaining capacity for each slot.

One 1800 mAh battery included.

The supplied cell stores 6.66 Wh and fits Olympus Li-50B, Panasonic VW-VBX090 and Pentax D-Li92 cameras listed in the compatibility table. Additional batteries are not in the pack, so users needing more than one spare must buy extra cells. The charger plates can be changed to support other battery form factors not covered by the included plate.

Questions about this item

How long will the 1800 mAh battery last in my Olympus XZ-1?

The 1800 mAh cell stores 6.66 Wh at 3.7 V. Actual shooting time depends on how often you use the LCD, flash, zoom and image stabilisation, so runtime varies by camera model and settings.

What does the 5 V 2‑3 A USB input actually deliver to each battery slot?

The charger accepts 5 V at 2‑3 A through Micro‑USB or Type‑C. It outputs 4.2 V at 800 mA for one or two batteries, dropping to 500 mA when three or four are charging simultaneously.

Will the 3.5 by 2 by 2.5 inch charger sit flat on my desk and hold four batteries securely?

The compact unit measures 3.5 × 2 × 2.5 inches and has four independent slots with spring‑loaded contacts. Each slot shows charge status and capacity on the built‑in display.
