NITECORE UI1 USB Charger for 18650/21700/18350/20700 Batteries

Lightweight and portable outdoor charging solution

The NITECORE UI1 is a portable USB-C battery charger with a max output of 1000mA for large-sized 20700, 21700 Li-ion batteries and more. It features a USB-C input with automatic adoption for optimal charging modes and multiple charging safeguards. Portable, lightweight and constructed from fire-retardant PC materials, this battery charger is fearless of the rough outdoors.

Maximum and Low Current Charging
Available for low current charging below 2.9V for protecting batteries and maximizing battery cycle durability. When a battery with a voltage below 2.9V is inserted, the NITECORE UI1 USB Charger automatically accesses Low Current Charging Mode with a charging current of 100mA. When a battery with a voltage of over 2.9V is inserted, the charger accesses Standard Mode with a max charging current of 1000mA.

Over-Discharged Li-ion Battery Activation
The NITECORE UI1 is capable of activating over-discharged Li-ion batteries with a protective circuit. After battery installation, the charger will test and activate the battery before charging.

Multiple Charging Safeguards
The NITECORE UI1 USB Charger boasts multiple charging safeguards for protective measures. Anti-short circuiting and reverse polarity protection activates if the battery is inserted with polar reversed or short-circuited, signalled by flashing all 3 indicators to show an error. When the charger is overheated, intelligent thermal protection automatically regulates charging current to protect the charger and battery. And finally with the automatic termination, upon charging completion, the NITECORE UI1 shows all 3 indicators glowing steadily and automatically ceases the charging process.
