Do you need a power supply that provides quality power and is small and portable? This power generator with automatic shut-off and a reset button is very easy to use. It supplies a pure sinusoidal signal with the voltage and frequencies of the alternating current being strictly controlled by the alternator. This results in a stable power supply. The generator is protected by means of a low oil level indicator as well as protection against overloads, voltage drops and overheating. Includes a cigarette lighter and USB (depending on model).
