A digital air compressor that plugs into your car’s ciggy lighter – great, right? Well, if you can deal with the embarrassment of the earth-shattering noise it emits, then yes. You’ll need to have a lot patience too, because you can pump up a tyre faster with a track or hand pump.
As well as manual inflation there’s an automatic pre-setting mode, which works okay. This multi-use compressor can inflate airbeds, dinghies and the like, so if you have a family or go camping frequently it might be up your alley.
Otherwise, you’d be better off spending your money on a decent track pump to store in your car.
