The GBC INV3-12-3000-A is a modified-sine DC-to-AC inverter that accepts 10–15V DC input from a 12V battery and delivers 220–240V AC output at 50/60Hz to two Schuko sockets. Its 3000W nominal power and 6000W peak handle high-demand appliances including desktop computers, laptops, tablets, TVs, DVD players, and gaming consoles.

SoftStart technology ramps up voltage gradually on startup to protect connected devices. Input is via crocodile clips, making connection to a car or leisure battery straightforward. A USB port provides an additional low-voltage charging output. Protection functions include low-battery alarm, undervoltage shutdown, and overvoltage shutdown.
