Pramac P3500i/O 3.3kW Petrol Inverter Generator with USB, PowerRush™ & Economy Mode | Stage V

The Pramac P3500i/O 3.3kW Petrol Inverter Generator is a compact yet powerful portable generator designed to deliver clean, stable electricity for a wide range of professional and leisure applications. Combining advanced inverter technology with exceptional fuel efficiency and low operating noise, it is the ideal choice for caravans, motorhomes, camping, outdoor events, workshops and emergency home backup.

Powered by a dependable Stage V OHV 4-stroke petrol engine, the P3500i/O delivers a maximum output of 3.3kW with a continuous output of 3.0kW, providing reliable power for appliances, power tools and sensitive electronic equipment including laptops, televisions, battery chargers and mobile devices.

Pramac's advanced pure sine wave inverter technology ensures a stable electrical output, protecting valuable electronics from voltage fluctuations while delivering smooth, dependable performance.

A standout feature of the P3500i/O is Pramac PowerRush™ Technology, which temporarily increases electrical current above the rated output when starting motors or high-demand appliances. This allows compressors, pumps and other inductive loads to start more easily without causing overload shutdowns.

For improved fuel economy, the integrated Economy Mode automatically adjusts engine speed to match the connected load, reducing fuel consumption, lowering noise levels and extending runtime. With its 9-litre fuel tank, the generator provides up to 5.5 hours of runtime at 75% load, making it ideal for extended use away from mains electricity.

Designed for maximum portability, the P3500i/O features a lightweight compact design with an integrated carrying handle for easy transportation. Dual 230V UK domestic sockets provide convenient plug-and-play operation, while dual USB charging ports allow you to charge phones, tablets and other portable devices without additional adapters.

Safety is enhanced through the automatic low oil shutdown system, which protects the engine from damage by automatically stopping operation if oil levels become too low. The generator is supplied complete with an oil bottle and filling funnel, allowing it to be prepared for use quickly and easily.

Whether you're travelling, working remotely or preparing for emergency power outages, the Pramac P3500i/O delivers dependable, quiet and fuel-efficient portable electricity wherever you need it.
