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 long running time on its large 7.5L tank means fewer refuelling stops during a long weekend away or extended off-grid stay. The panel features 2x 13A BS sockets, so your devices can be plugged straight in.
Key Benefits
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. That means fewer interruptions during a long weekend away or an extended off-grid stay. Confirmed runtime figures are pending factory verification.
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 reduced engine speed during lighter loads, lowering both noise and fuel consumption. Confirmed noise figures at 7m are pending factory verification.
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.
Who Is This For?
This generator is ideal for:
- Caravan and motorhome owners who want extended runtime without refuelling
- Off-grid leisure setups where long running time between fills matters
- Boat owners needing long-running portable shoreside power
- Builders and anyone wanting lightweight power in the field
- Allotment holders and rural property owners needing seasonal off-grid power
- Anyone who values simplicity and long running times over feature-packed panels
This generator is NOT ideal for:
- Those needing industrial blue sockets or higher-amperage outlets — consider the HY3900Si or HY6250SEi
- Applications requiring electric start — this model uses recoil start only
