A micro mobile phone battery charger for nickel hydrogen and lithium ion batteries, having advantages of high charging efficiency, quick charging, being adaptable for use with different voltages, and compactness. includes a casing, a rotary concealable charger plug, an internal circuit device, and battery terminals arranged to retain the battery in the housing and eliminate the need for lead wires. The internal circuit device, includes an overload, over-voltage protection circuit, an electromagnetic interference filter circuit, a voltage stabilizing circuit, an oscillation circuit, a direct current rectifying circuit, a car charge direct current input protection circuit, an alternating current filter circuit, a detection circuit, and an automatic power interruption system. The current is automatically adapted so that the input voltage range is from 90 to 250V to adapt to municipal currents of 110 to 240V and car charging.
