If it’s for tyre warmers then >2kw power wise, if you prefer quiet’ish then a suitcase which generally have inverters and vary the rev like Honda EU range one or the Chinese clones. Budget for £200 to £1.5k depending on which option you go for.
It's to run a hot air gun, the current option is my cordless version. Just need to figure out what the draw is. Plus my Son is interested in going to trackdays with the old folk.
Looks like this is the winner, Hyundai 3200W / 3.2kW Petrol Inverter Generator, Pure Sine Wave Output, Lightweight, Quiet with Electric Start | HY3250SEi
Just brought a new honda eu70is with all the extra bits-n-bobs. If you want the best electrical pure sine-wave for equipment don't skimp. Because our expensive phones & laptops & batteries need smooth true sine wave low harmonic distortion signals to last! https://www.hampshiregenerators.co.uk/ large cover, will be tweaked so both ends are unzippable. Honda lifting kit for eu70is when I have my hoist for lorry, luckily the central frame rod sat pukka. Overall view of inital purchase kit, without stainless exhaust & vent kit. I have a EU26 (obsolete) for my static-caravan jobbie so two service kits were brought for both genies. EU70 kit is emergency power for my lorry project & power during its contruction phases. https://www.simplysoundandlighting.co.uk/ PCE ST ANTON Distribution box 32A with 10-meter cabling & https://www.geargb.co.uk/ remote (better than OEM remote) strapped to it. https://www.powershackshop.co.uk/ very kindly made a specific lead for me, 16A RCD 13a waterproof to 16A outlet allowing me lights inside my container rather having several leads creating love-lines. ...so yes buy honda but you probably only need the eu30 size!
Something like this is worth considering if you're not after hours and hours of use: https://www.ebay.co.uk/itm/226550751322
