PRODUCT DETAILS
The Go Power! GP-400HD is an economical 400-watt modified sine wave inverter that turns 12 V battery power into 120 V AC for laptops, lights, small TVs, fans and battery chargers for cordless tools. Connect it to a 12 V battery, plug into its 2 AC outlets or the USB port, and go. Modified sine wave is the right choice for resistive and motor loads where price matters; for TVs, laptops on sensitive chargers and medical devices choose a pure sine wave model.
Built to the standard RV manufacturers install
Go Power! has designed mobile power since 1996 and is the inverter brand fitted at the factory by Jayco, Forest River, Thor and other leading RV builders. These previous-generation models are sold here at outlet pricing while stock lasts, backed by the same North American support team (part of Dometic). For the current lineup see the Smart Sine Wave and Advanced Sine Wave inverters.
Install it right
Use the Go Power! Inverter Install Kit sized 100–600W (GP-DC-KIT1) for correctly rated cables and a Class T fuse between the battery and the inverter.
