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.
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.
Connect laptops, televisions, games consoles and other sensitive electronics with confidence.
When you are drawing less than full load, ECO mode automatically reduces engine speed, in turn reducing noise.
At 21.15kg, it is still portable enough for one person to move.
ECO mode extends run time by reducing engine speed when demand drops, giving better fuel economy.
