The Ci4 is capable of up to a fast charging 4A speed in single bay. The Ci4 automatically detects Li-ion, Ni-MH and Ni-Cd batteries. Intelligent charging circuitry selects the optimal charging mode (CC, CV and dV/dt) for a given battery and each of the Ci4’s four microcomputer-controlled charging slots then monitors and charges the battery independently with an intelligent automatic power-off function terminates current when charging is complete. The Ci4 is available with fast charging mode when it is powered by a QC/PD supportive device or to a QC/PD adapter.
