Smart charger Nitecore Ci2 / USB-C

Nitecore Ci2 is a high-quality and intelligent battery charger with space for two batteries. Ci2 uses the latest technology and is compatible with almost all batteries. Ci2 automatically recognizes Li-ion, IMR, Ni-MH and Ni-Cd batteries and applies the appropriate charging method for each battery. Both charging channels of the charger work independently of each other and both channels recognize which type of battery is being charged and thus also know how to choose the correct charging voltage and stop charging when the battery is full.

Since both channels work independently of each other, different types of batteries can also be placed in them at the same time, if necessary. When charging two batteries, the charging current is 1000mAh per charging channel and when charging one battery, a faster charging current of 2A is obtained. When using fast charging, the charging current is up to 3000mAh when charging a battery.

Quick guide

1. Connect the power cable to the charger.

2. Place the battery in the charger, making sure the polarity is correct (plus and minus poles to the ends assigned to them). The charger starts charging after 2 seconds.

5. For safety reasons, the Ci2 charging unit stops charging after 10 hours at the latest (per charging channel). When charging is complete, remove the battery from the charger and disconnect the charger from the power source.

General safety data sheet:

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