Battery Charger Nitecore Ci12 Universal USB charger for Li‑Ion, NiCd, NiMH, 3A input 5/9/12V, plastic casing

The Nitecore Ci12 Universal USB charger is designed to charge a range of cylindrical rechargeable cells including Li‑Ion, NiCd and NiMH chemistries. Compact and lightweight, the charger accepts USB input voltages of 5V, 9V and 12V and delivers charging current up to 3A. The unit features LED indicators that display charging status and a durable plastic casing that makes it suitable for everyday home use, travel and fieldwork while meeting standard safety certifications.

Advantages

The charger supports multiple battery chemistries and automatically adapts to common cylindrical cell types, providing a flexible charging solution for different devices. Variable USB input compatibility (5V/9V/12V) allows use with a wide range of USB power sources and PD adapters. A maximum charge current of 3A enables faster charging for compatible cells, while LED indicators give clear feedback on charge progress. The plastic housing keeps the unit lightweight and resistant to typical wear from transport and handling.

How to use

Insert the battery cell into the charger following the polarity markings, then connect the charger to a suitable USB power source that supplies 5V, 9V or 12V. The charger will detect the cell chemistry and apply the appropriate charging profile. Monitor the LED indicators to determine charge progress; the indicators will change state when the cell reaches full charge. Disconnect the battery once the charging cycle is complete and allow the charger to cool before storing.

Recommendations

Use a USB power source rated for the intended input voltage and sufficient current capacity. Avoid charging visibly damaged or swollen cells. For best results, charge cells at appropriate temperatures and within manufacturer‑recommended limits; do not leave batteries connected to the charger unattended for prolonged periods.
