Hyundai Portable Petrol Inverter Generator 3300W 3.3kW Silent H3900Si
“Refund was approved and back in my account the same day.” - Deliver+ customer
The Hyundai HY3900Si delivers 3.3kW maximum (3.0kW continuous) power, making it ideal for larger caravans, motorhomes, camping and off-grid leisure. Powered by a reliable 144cc 4-stroke petrol engine, it provides the extra capacity needed to run a fridge, lighting, chargers and other appliances simultaneously. Advanced inverter technology produces a pure sine wave output, ensuring clean, stable power that's safe for sensitive electronics including laptops, TVs, games consoles and mobile devices. The ECOnomic mode automatically adjusts engine speed to match demand, reducing fuel consumption, lowering noise levels and extending runtime when full power isn't required. Despite its higher output, the HY3900Si weighs just 21.15kg, making it portable enough for one person to transport. It also features a 16A industrial blue socket for higher-draw equipment, while the 3-in-1 digital display provides real-time monitoring of voltage, frequency and operating hours. Combining dependable performance, fuel efficiency and clean inverter power, the HY3900Si is the ideal portable generator for leisure, camping, caravanning and backup power applications.
