Nitecore UMS2 USB battery pack (max 3000mAh)

Nitecore U-series dual-slot smart charger with USB connector. The charger is suitable for most battery types. Batteries that can be charged at the same time can be different from each other.

Nitecore UMS2 is a high-quality, automatic smart charger that is compatible with almost all batteries. The charger automatically detects Li-ion, Ni-MH, IMR, LiFePO4 and Ni-Cd batteries and applies the appropriate charging method. Two independent charging channels detect the type of battery being charged and can select the correct charging voltage and stop charging when the battery is full. Batteries charged at the same time can be different from each other. When charging two batteries, the maximum charging current is 2000mAh per charging channel. With one battery, using only the second channel, the maximum charging current is 3000mAh! You can choose the charging power you use between 100 mA -3A. The charger automatically selects the appropriate charging power for low-power batteries (automatic operation does not work with LiFePo4 or 3.8V LiIon batteries).

The charger has automatic polarity detection, automatic charging stop for a fully charged battery, and overcharging protection.

User manual

- Connect the power cable to the charger.

- Place the battery in the charger, making sure the polarity is correct (plus and minus poles to the indicated ends). The charger will start charging after detection.

- For LiFePo4 batteries, the charging voltage must be selected manually

- The charger automatically detects the battery's charging voltage and current (except LiFePo4). If you want to select the charging current yourself, you must install the battery in the charger, and then select the desired charging current by pressing the button above the charging slot for the battery.

- When charging is complete, remove the battery from the charger and disconnect the charger from the power source.

General safety information:

When charging a Li-ion battery, a charger suitable for the purpose must be used. Do not use with other brands, types or models of batteries! Do not leave the battery in the charger for more than 24 hours and always charge the batteries under supervision!
