P1 P4000i 4000W Portable Petrol Inverter Generator

Suitable For Power Tools
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.

New Display 
The new LCD display makes it easy to monitor the performance of the generator, displaying voltage, frequency and hour count.

Variety Of Uses
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.

User Friendly
The P4000i inverter generator is extremely popular for large motorhome use and it’s built to be user-friendly with low maintenance requirements.

Safety Features
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.

ECO Mode
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.

Awesome generator
Just received new P1 4kw generator. Absolutely brilliant bit if kit. Used bog std open frame gens until now and it’s it’s like chalk and cheese in comparison.

You just fill with supplied oil 600ml and using screw in oil filler neck so no mess. Add fuel and the supplied fuel stabiliser so fuel doesn’t stagnate if gen not used often. Connect the battery plug turn on and press start. It’s that easy. Started on first press of starter and every time after.

Oh and telescopic handle is brilliant too

Highly recommended you won’t be disappointed with this purchase

P400i inverter generator
Very good quality generator with many features not included on other sets. The most impressive feature is the quietness, at 53db it is incredibly quiet. You can have a conversation with the generator running without having to raise your voice!
Secondly it is very fuel efficient, with the added feature of an accurate readout of time left according to fuel and load. Expensive compared to other options, but worth it.
