REVIEW
My £20 ebay cheapie died after two years, longer than expected. And the bulk and faff of my ancient, 12-volt wired Cycle Pump remains off putting. Once you go wireless it’s hard to go back. Bring on the day when all electrical household items are cable-free!
I like to think the 20% saving right now at Halfords on the Michelin Mini Rechargeable Inflator covers the extra you pay for Michelin branding. The handy pump is about 8 inches or 20cm long, and comes with a tiny LED ‘phone’ light, and adapter nozzles for pushbike Presta valves and a football clipped to the swing-out hose with a fold-lever tyre valve connector. Plus there’s a flimsy bag.

Jabbing the blue button won’t work. You wake it up by swinging out the hose at which point the LED lights up and the thing is live. Only then does the blue button set it off. You can scroll through four fixed-psi presets (bike 45, moto 34, car 32, football 8psi). It says adjustable which is true but that doesn’t mean ‘storable’ afaict. There’s a fifth, empty one to set as you like. But that isn’t stored either. I did read the leaflet and tried a few times. This all reminds me of the TPMS glitches (see below). Or maybe it’s as it was supposed to be
But honestly, you don’t really need presets. Just clip on, hit the blue button and watch the numbers rise to the pressure you want. Then hit the blue button again and it stops.

Fully charged out of the box, I inflated the new rear Michelin Wild tyre on my Serow from empty to 26 psi in 2:38s. The gadget vibrated a bit but didn’t get too hot. The battery dropped to ¾, but recovered back to full four bars in a few minutes.
All in all, so far so good. I hope it does better than the flakey Michelin branded TPMS I tried a few years ago. The rear factory tubeless wheel on the Serow tends to leak on some tyre combos, so the easy-to-use pump may be getting more use in Morocco this winter.
