1000W Auto Step Up & Step Down Voltage Transformer Converter

Our advanced auto-step-up and step-down technology (US Invention Patent No. US9225259 B2) means that manual selection of input voltage is no longer necessary. The transformer automatically recognizes the input voltage and converts it to the corresponding voltage.
The perfect solution for all your voltage conversion needs! With 4 AC outputs, including 2 US standard sockets and 2 universal sockets, this transformer can auto-convert 110-120V to 220-240V or 220-240V to 110-120V (except for the Big South African plug).
The SEYAS Transformer Converter is CE, FCC, and RoHS certified and boasts 7x24hrs constant work time with 100% loading capacity. Resettable buttons on the back of the transformer allow for easy restarting when auto shut off occurs due to overcurrent.
A built-in 380 Joules surge protector is ideal for computers and household electronics, and 2 input mini circuit breakers prevent overcurrent or short circuit.
