The GBC INV3-12-600-C converter is a modified sine wave inverter that converts 12 V DC to 220–240 V AC. It powers computers, laptops, tablets, MP3/MP4 players, TVs, and DVD and CD players when mains power is unavailable. SoftStart technology limits the starting current, while the USB port allows portable devices to be charged at the same time.

The input connects to a vehicle battery or standalone battery using alligator clips, and the output is via a Schuko socket. The aluminium housing includes an on/off switch and a cooling fan.
