The Ci4 from Nitecore is a four-slot, superb charger that matches Li-ion and Ni-MH/Ni-Cd batteries. The Ci4 incorporates an optimized IMR battery charging program, which monitors the entire charging process to ensure that the cut-off voltage is always within safe limits, extending the lifespan of the BTM Oracle. The USB-C charging port is able to reach a maximum charging current of 3000 mA, which triples the charging speed, and is available with a reversible plug-in of the charging cable with automatic detection of QC or PD input, allowing users to enjoy the inexhaustible power supply from multiple input sources to avoid outdoor power shortages. Besides, a dual external protection system allows the charger to have both extreme cooling performance and endurance in complex outdoor environments.
