The top 6 at a glance
A tyre inflator is a small electric compressor that lives in the car and tops up a soft tyre on the drive or at the roadside. Most plug into the car’s 12V socket, so there’s nothing to charge; cordless ones run from a rechargeable battery and do without a cable, but need charging now and then.
Digital models stop by themselves at the pressure you set, which makes the job hands-off; with a dial gauge, you stop it yourself. Readings come in PSI, and on many models bar and kPa too. Most here also come with adaptors or modes for bike tyres and balls, and have a built-in light for the roadside after dark.
What matters
- A cable long enough to reach the far rear tyre, or no cable at all.
- A clear, bright display you can read outdoors.
#1AstroAI S1 Digital Tyre Inflator (12V)
£10–£20
- Stops at the set pressure
- Built-in LED light
- Cuts out above 16V
Plug it into the car’s 12V socket and set the pressure: it stops by itself when the tyre is right. A 3m power cord and 48cm hose reach the tyres, and an LED light comes on whenever it’s powered. None of the three higher scorers below sells nearly as many.
What owners say: Quick and accurate, owners say, with pressure control they rate, and small and simple enough to keep in the boot instead of paying at the forecourt machine.
A closer look: Keep the engine running while it works so the car battery isn’t drained. If the screen shows U-H, the voltage is too high and it has cut out to protect itself; it carries on once the voltage drops back below 16V.
Best for: Long power cord

#2Lamicall Cordless Tyre Inflator (VHEP02, 6000mAh)
£30–£50
- About 35 minutes’ pumping per charge
- Fast 28 L/min airflow
- 360° swivel valve connector
A 500g cordless pump whose 6000mAh battery runs for about 35 minutes of pumping, plenty for a round of top-ups between charges. Five modes cover car, motorbike, bike, ball and a custom pressure, and it remembers the last setting, so the next top-up is one press.
What owners say: Owners say topping up tyres is quick and easy, and they rate its build, its pumping speed and how neatly it fits the glovebox.
A closer look: The 30cm hose screws on, and its 360° swivel valve reaches a valve at the bottom of the wheel without kinking. A steady green light means it’s fully charged, and it doubles as a power bank and an emergency light at the roadside.

#3AstroAI C2 Corded and Cordless Tyre Inflator (20V)
£50–£75
- Runs on battery or 12V
- 20 minutes’ continuous pumping
- Extra extension hose included
- Heavy at 1.15kg
Runs from its own 20V battery or the car’s 12V socket, and the metal cylinder is built for 20 minutes of continuous pumping, enough for all four tyres; the battery pack comes off as a power bank.
What owners say: Compared with plug-in models, owners find it easier to use, with a battery that holds its charge, quick inflation even on van tyres and accurate readings of the set and current pressure, and they like the carry case.
A closer look: Clip on the extended quick-connect hose for the far tyres rather than walking the pump round the car. The battery fills in about two hours over USB, and it remembers the last pressure you set.
Best for: SUVs and MPVs

#4Wirelume Cordless and Corded Tyre Inflator (CLB-6010)
£20–£30
- Runs on battery or 12V
- Stops at the set pressure
- Three-mode LED torch
A 6000mAh cordless pump that also runs from the car’s 12V socket on the cable in the box, so a flat battery doesn’t end the job, and it doubles as a power bank over USB-A.
What owners say: Ready to use from the moment it’s unboxed, owners report, and it fills tyres efficiently in a small, simple package.
A closer look: A full charge takes three to four hours, so give it one when it arrives and again after a long session of pumping. Screw the hose fully onto the valve before pressing start, or air escapes round the seal and the reading jumps about.
Best for: Pumping when its battery’s flat

#5SFGSUP Cordless Tyre Inflator
£10–£20
- Light at 435g
- Compact 13cm body
- Stops at the set pressure
- Short 15cm hose
Small enough to live in the glovebox, and it stops automatically at the pressure you set, so topping up the tyres takes a couple of minutes on the drive. Its 4000mAh battery also charges a phone over USB.
What owners say: Owners find it a handy portable pump that stores easily in the car and adjusts the pressure simply, saving trips to the tyre shop; battery life gets a mixed verdict.
A closer look: Check the tyres when they’re cold, before a drive, and you’ll find the right pressures in the car handbook or on a sticker inside the driver’s door or fuel flap. The custom mode takes any figure from 3 to 150 PSI, for a trailer or wheelbarrow tyre.
Best for: Smallest to store

#6Ring RAC610 Tyre Inflator with Gauge
£10–£20
- Reads PSI, kg/cm² or bar
- Dial gauge, no auto-stop
- No built-in light
- Loud at 90dB
The simplest option: a small 12V compressor with a dial gauge and a 2.9m power cable, light enough at 650g to tuck in beside the spare wheel and forget about. The gauge reads in PSI, kg/cm² or bar.
What owners say: Owners find it quick, easy and far less effort than a foot pump, and small enough to store beside the spare wheel, though several report it breaking down after a short time.
A closer look: Pause now and then to let the needle settle, as a dial gauge can read a little high while the motor is going. It’s loud but quick, and small enough to leave in the car all year, ready for a soft tyre on the school run. Ring now lists the RAC610 as discontinued on its own site, though it’s still sold new on Amazon.
