Kastar LI-90B Triple USB Charger

The Kastar LI-90B is a triple USB battery charger designed for Olympus Li-90B and Li-92B cells. It charges up to three batteries simultaneously and shows individual status on an integrated LCD screen. The unit accepts 5 V 2 A input via Micro-USB from a wall adapter, car charger or computer. Compact dimensions of 3*2*1 inch make it easy to pack for travel.

Suits Olympus TG and Stylus shooters.

Photographers using Olympus Tough TG-series or Stylus SH, SP, TG and XZ models that take Li-90B or Li-92B batteries can charge three spares at once. The charger only fits those specific Olympus cells, so owners of cameras using different battery formats will need a separate solution. It also does not support AC mains input directly without a USB power source.

Charges three Li-90B or Li-92B cells at 4.2 V 0.5

Each of the three slots delivers 4.2 V at 0.5 A, matching the requirements of compatible Olympus lithium-ion packs. The LCD reports real-time capacity for every bay so you can confirm full charge before heading out. Total input power is 10 W from any 5 V 2 A USB source.
