EXCELLENT
When a 2kW generator is not quite enough for your setup, the next step up matters. The Hyundai HY3900Si delivers 3.3kW / 3300W maximum output and 3kW / 3000W continuous from a 144cc four-stroke engine. That extra headroom means you can run a caravan fridge, charge multiple devices, power lighting and still have capacity left over. The pure sine wave output keeps sensitive electronics safe, while the ECO mode stretches your fuel when full power is not needed. At 21.15kg, it is still portable enough for one person to move.
Enough power to run multiple appliances at once
With 3.0kW continuous output, the HY3900Si handles combinations that smaller generators cannot. Run a fridge, charge your devices and power lighting simultaneously without worrying about overload. Ideal for larger caravan and motorhome setups.
Pure sine wave output for clean, safe power
The inverter technology produces stable electricity with low harmonic distortion. Connect laptops, televisions, games consoles and other sensitive electronics with confidence.
ECO mode for fuel efficiency and reduced noise
When you are drawing less than full load, ECO mode automatically reduces engine speed, reducing noise and giving better fuel economy. This extends the runtime in between refueling.
Industrial blue socket for higher-draw equipment
The HY3900Si features a 16A industrial blue socket for connecting equipment that draws more than a standard 13A connection. The 3-in-1 digital meter lets you monitor output in real time.
