Lives in the boot
Works well, easy to figure out, good value. A bit noisy — it is a pump — but inflates quickly. Compact enough to ride around with me for monthly pressure checks.

Preset pressure without guessing at the garage pump
Set your PSI, screw onto the valve, plug into the 12V socket — the AA inflator stops when it hits target. Three-metre cable reaches rear tyres on most hatchbacks.

Worth a look
The AA badge matters when you are at a petrol station air line that ate 50p and still left you soft. Screw-on valve is slower to attach than a clip — but it leaks less on cold mornings.
- Digital preset 10–50 PSI with automatic shut-off
- Screw-on valve connector — less leakage than clip-on types
- 3m power cable reaches rear wheels on most cars
- Built-in LED torch for night-time checks
- Compact enough for under-seat or side-pocket storage
- AA brand — familiar face at the roadside
What it does
Digital gauge, auto shut-off, and a torch for late-night kerb checks — sized to live in the boot year-round.
Preset PSI
Dial your number, hit start, walk away until it beeps. Reading matched our track pump within 1 PSI on a cold tyre — good enough for motorway peace of mind.
Screw-on valve
Thread onto the stem instead of clipping — takes ten seconds longer but holds pressure while the motor runs. Less hiss than old brass-clip pumps owners compared it to.
Noise
It is a tyre pump — expect drill-level volume. Fine at a services air bay; at 5 a.m. on a terrace street you will feel self-conscious.
Cable storage
Three metres reaches rear tyres on a Focus-sized car. Cable bay lacks a cover on some units — the lead can spring loose in the boot unless you strap it.
What to watch
No carry case in the box — budget a small bag if you want the hose and 12V lead together. Needs the engine running or a live socket; not for cordless top-ups away from the car.

Borrowed my son's — bought my own
Precise and simple. Small enough for tight boot space. Used it at 5 a.m. and was conscious of the noise, but it did the job in minutes.

Screw thread not brass
Efficient pump and stops on the dot. Power cord bay has no cover. Screw fitting is fine but not as precise as an older model with a brass head — still better than clip-ons.

Torch saved a night job
PSI reading is exact. Torch is useful in a dark car park. Light, compact, and I have used it on grandchildren's bike tyres too.

Better than my old handheld
Last year's cheap pump broke — this one feels better made. Screw onto the valve, select PSI, done. Totally recommend.

Screw-on is the win
Works quickly. Screw connector beats the old clip type — no escaping air while you fumble. Long lead reaches rear tyres easily.

Good pump — pity about the bag
Long lead, clear display, easy to use. Only gripe is no case to keep hose and plug together in the boot — using a freezer bag for now.
Setup
Run it once on a warm tyre at home so you know how loud it is before a 5 a.m. flat.
- Step 1
Engine on
Plug into a live 12V socket with the engine running — most pumps draw more than a phone charger and can trip weak sockets.
- Step 2
Screw the valve
Thread clockwise until snug — do not overtighten on plastic stems. Zero hiss means a good seal.
- Step 3
Set PSI and wait
Pick your target (door sticker on the B-pillar). Let it shut off on its own; bleed 1 PSI if you prefer a softer ride.
