2,050 W stated, 23 kg and 5 hours at half load. Mecafer is a well distributed French brand, but its PDF sheet mixes this generator with an air compressor: continuous power cannot be read cleanly, so the main criterion drops out and no score is given.

Not scored: only 15% of the scale is covered, or the main criterion is missing. Below 60 percent, a score would reward the maker who publishes least. Weighting: Continuous power 40 %, Price per continuous kW 25 %, Noise at 7 metres 20 %, Weight 15 %.
Choose it if
- Occasional backup and leisure, around 1.5 kW of real use.
- Preferring a brand with European service.
- A budget of around $380.
Skip it if
- Comparing on figures: continuous power is not published cleanly.
- Power hungry site tools.
- Looking for the quietest machine.

Before you plug anything in
- Never in an enclosed space. Not a garage, a basement or a shed, even with the door open. A generator gives off carbon monoxide, an odourless gas that kills. Outside, away from doors and windows.
- Never wired straight into the consumer unit. Back-feeding a house through a double-male lead sends current into the grid and endangers the people working on it. The connection goes through a changeover switch fitted by a qualified electrician.
- An extension lead rated for the load. A lead that is too thin heats up. On site, 2.5 mm² cable and a sensible length.
- Store fuel outside in an approved can, and refuel with the engine off and cool.

Frequently asked questions
Where does this machine's score come from?
It is calculated, not awarded. Five measurable criteria are weighted, and each value is mapped onto a scale relative to the other machines in the comparison. For this machine, 15% of the scale could be applied: criteria the maker does not publish drop out rather than being replaced by an estimate.
How much power does a self-build site need?
Add up the machines that run at the same time, then allow a margin. An 800 W mixer and a 1,400 W circular saw already ask for 2,200 W continuous, plus the start-up peak. For that pair, a machine around 2 kW continuous is too tight; aim for 3 kW.
Can an inverter generator run a laptop?
Yes, that is the point of it. Inverter technology produces a clean sine wave, usually under 3 percent distortion, which electronics tolerate. A conventional AVR generator suits power tools but not always sensitive devices.
