UC-92 USB charger for Olympus batteries

The OM System UC-92 is a compact USB charger built for Olympus LI-92B and LI-90B lithium-ion batteries. It draws power from any standard USB port to replenish a single battery at a time. An integrated LED indicator shows the charging status while the unit operates. This accessory suits photographers who want a lightweight way to keep spare cells ready during a shoot.

Ideal for single-battery USB charging.

The charger handles one proprietary battery per cycle, making it a good fit for solo shooters or as a backup unit in a camera bag. Photographers who need to charge two or more batteries simultaneously will find the single-slot design limiting. It also cannot charge other battery formats or serve as a power bank for phones or tablets.

One battery in roughly 2.5 hours at 800 mA

A full charge takes approximately 2.5 hours when connected to a regular USB source delivering up to 800 mA. That rate restores one LI-92B or LI-90B cell from empty to full within a typical lunch break. The single-channel layout means total charging time scales linearly with the number of depleted batteries you carry.

Questions about this item

Do I need a separate USB power adapter or computer port to run the UC-92 charger?

Yes — the UC-92 draws power from any standard USB port, so you will need a USB power adapter, computer, or power bank with a free USB-A socket to operate it.

Can the UC-92 charge my older LI-90B battery as well as the newer LI-92B?

The charger supports both Olympus LI-92B and LI-90B batteries, so your existing LI-90B will charge normally alongside the newer type.

How do I know the UC-92 has finished charging a battery?

The built-in LED indicator changes state when the roughly 2.5-hour charge cycle for a single LI-92B or LI-90B is complete.
