R3 GERMAN Trimmer Charger for Mi Corded & Cordless Waterproof Beard Trimmer An efficient power conversion ratio reduces the voltage stress across the main connector. It maintains a constant and consistent voltage output level, whilst varying the current to cope with the demands. In case of current leakage appearing on the metal body of the equipment, the 3-Pin socket prevents it by safely discharging it to the ground and safeguarding the user from any electric shock while using the equipment. The Smoothing/Filter capacitor smoothes the voltage level fluctuations to an extent to lower the Ripple Operating Noise. In the event of a short circuit and voltage overload, the efficient in-built circuit shuts down the system and prevents the battery from potential deformation.
