Long-running 3.3kW inverter generator with extended fuel capacity for weekend-long off-grid power. Hyundai 3.3kW max output, inverter generator with open framed styling. Ideal for powering sensitive electronics such as laptops, phones, travel fridges or any appliances within your motorhome, caravan or when camping without access to power. The panel features 2x 13A BS sockets, so your devices can be plugged straight in.
Long running on a 7.5L tank
The 7.5L fuel tank and 208cc engine combination give you a long running time between refuels — one of the best in its output class. On a full tank, the HY3750i runs up to 14 hours at light load (10%) and 5.8 hours at 50% load. That means fewer interruptions during a long weekend away or an extended off-grid stay.
3kW continuous pure sine wave output
The HY3750i produces 3.0kW of clean, inverter-regulated power. The pure sine wave output is safe for laptops, phones, televisions and other sensitive electronics, while still providing enough capacity for small appliances and lighting.
Quiet running inverter technology
Inverter generators regulate engine speed to match the load, making them significantly quieter than conventional fixed-speed generators. The HY3750i runs at 72 dBA at 7m under 50% load — significantly quieter than a conventional generator of comparable output. ECO mode reduces engine speed further during lighter loads, lowering noise and fuel consumption.
Simple, practical panel design
The HY3750i keeps things straightforward with 2x 13A BS sockets. No unnecessary complexity — just reliable power outlets ready to connect your equipment.
Euro V 4-stroke engine for sustained performance
The 208cc four-stroke engine provides ample power reserve for continuous running. The larger displacement means the engine works less hard at typical loads, which can contribute to longer service life and smoother operation.
