The P4000i is a compact yet powerful portable inverter generator powered by the Hyundai IC225D 4-stroke single cylinder air cooled engine, providing a reliable power source.

Producing 3800w the P4000i is ideal for caravans and motorhomes as it allows you to take the modern luxuries from home with you wherever you go.

The P4000i symmetrical design allows you to store it and transport it easily.
Weighing only 48kg and measuring just 630x400x520mm, the folding front handle and fixed rear handle plus heavy duty rear wheels make transportation easy across a variety of surfaces.

It houses a new inverter board designed to cope with the extreme inductive loads applied when using power tools and electric motors with high startup currents.
The new LCD display makes it easy to monitor the performance of the generator, displaying voltage, frequency and hour count.

The control panel features two 230v sockets for use with any appliance which use a standard 3-pin 13A UK mains plug, as well as a 12v DC battery charging outlet and a USB port for charging mobile phones and ipads.

It’s ideal for a variety of uses. Producing a pure sine wave output is is ideal for powering most electronic equipment.

The P4000i inverter generator is extremely popular for large motorhome use and it’s built to be user-friendly with low maintenance requirements.
Digital overload protection will shut the generator down should the load pass the maximum threshold, and low oil shutdown also turns off the generator should the oil levels drop too far.

Already an economical generator, the P4000i also has the added benefit of an “ECO” mode which, when selected, will lower the engine revs to match the load being applied, which in turn increases the fuel economy, lowers the noise produced and extends the lifespan of the engine.

must have for camping
This has completely changed my camping experience. I can now take my hairdryer and other heat tools with me and use them with ease. We also used it to power our TV and charge our phones. We had no issues and look forward to using it again.

Great price
I did a lot of research before buying and found this was by far the cheapest. It arrived next day and looks great. Comes with an extendable handle so it is extremely easy to pull along. The screen is a great feature which makes it easy to monitor. We will be taking this with us every time we go camping.
