Hyundai 3.3kW / 3300W Inverter Open Framed Generator, Recoil Start, Pure Sine Wave | HY3750i
3.3kW of power from just 26kg — long-running, portable inverter power for the site and the trade
The Hyundai HY3750i is a 3.3kW open-frame inverter generator built around one stand-out quality: power-to-weight. It delivers 3.3kW maximum and 3.0kW continuous from a unit weighing just 26kg — a conventional generator of similar output can weigh almost double, typically around 45kg. The pure sine wave output safely runs sensitive electronics such as laptops and phones, as well as power tools and battery chargers on site without access to mains power. The large 7.5L tank gives long run times and fewer refuelling stops, a digital readout keeps you on top of volts, frequency and running hours, and the panel's 2x 13A BS sockets let you plug straight in.
Key Benefits
High power-to-weight: 3.3kW from just 26kg
The HY3750i's biggest advantage is how much power it packs into a light, carry-anywhere unit. You get 3.3kW maximum and 3.0kW continuous output from just 26kg, where a conventional generator of similar output typically weighs around 45kg. That makes it genuinely easy for one person to lift into a van, carry across a site or reposition around a job.
3.0kW continuous / 3.3kW maximum pure sine wave output
The HY3750i produces clean, inverter-regulated power. The pure sine wave output is safe for laptops, phones and other sensitive electronics, while the 3.3kW peak helps handle the startup surge of power tools, compressors and pumps. Bear in mind electric motors can draw two to three times their rated power on startup.
Long running on a 7.5L tank
The 7.5L fuel tank and 208cc engine combination give you one of the longest run times 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, meaning fewer interruptions during operation.
Digital readout keeps you informed
An integrated digital display shows output voltage, frequency and running hours at a glance, so you can keep an eye on the load and track service intervals easily.
Simple, functional and easy to maintain
No unnecessary complexity, just a straightforward panel with 2x 13A BS sockets ready to use. Routine maintenance is simple and service parts are readily available, keeping the HY3750i easy and inexpensive to look after over its life.
