Rank #8 in Best Portable Generators 2026: 10 Ranked, Start vs Running Watts
AIVOLT 1200W Petrol Inverter Generator
Price and rating as shown on Amazon when we collected them. Both change.
The AIVOLT 1200W Petrol Inverter Generator sits at number 8 in this guide, at £199.49 with a 4.4 average from 340 ratings. It is a 2.5-litre-tank inverter unit aimed at camping, caravans and small backup jobs, and the listing's own numbers disagree about how much power it puts out continuously: the specification table lists 1200 W of running wattage, the bullet text describes 1.2 kW starting and 1.1 kW continuous, and a separate Output Wattage field reads 1260. Those are three different figures for the same machine.
The listing also cannot agree with itself on the engine. The bullets describe a 60 cc four-stroke OHV air-cooled engine, while the specification table gives the engine displacement as 149 cubic centimetres. A third field is wrong in a different way: the Colour entry reads "1.1kw", which is a power rating rather than a colour, even though the bullets elsewhere call the casing bright orange. Everything on this page comes from the Amazon listing for the AIVOLT VS1400101 and from reviews left on it — we have not tested the generator ourselves.

Questions people ask
What is the continuous power output of the AIVOLT VS1400101?
The listing gives three different answers. The specification table lists running wattage of 1200 W, a bullet describes 1.2 kW starting and 1.1 kW continuous, and a separate Output Wattage field reads 1260. AIVOLT does not say in the listing which of these is the sustained figure.
What size engine does the AIVOLT VS1400101 have?
The bullet text says a 60 cc four-stroke OHV air-cooled engine with 100 per cent copper windings. The specification table for the same model lists engine displacement as 149 cubic centimetres.
How long will the AIVOLT VS1400101 run on one tank?
The fuel tank is 2.5 litres. A bullet claims up to 10 hours of consistent power, then breaks that down as 7 hours at 25 per cent load, 5.5 hours at 50 per cent, 4 hours at 75 per cent and 3.1 hours at 100 per cent, with Eco mode extending it further. The specification table simply states 10 hours.
How loud and how heavy is it?
The bullets state 12 kg and 58 decibels at 25 per cent load, and claim the AIVOLT VS1400101 is around 15 per cent lighter than many other compact generators of similar power. One reviewer on this page questions how portable it is in practice.
What can I plug into the AIVOLT VS1400101?
The control panel has a standard 230V three-pin socket, two USB charging ports (Type-A and Type-C), a 12V DC output and parallel connectivity. The specification table lists three total power outlets.
What is in the box with the AIVOLT VS1400101?
The package includes the 1200W petrol generator, a spark plug wrench, an oil funnel, a 12V DC battery charging cable, a screwdriver, a quick-start guide, a UK plug and a user manual.
