Autofy Sonic Auto-Cut Tyre Inflator Review (2026): 150 PSI, Digital, Rs 1,399
- The Autofy Sonic is a corded 12V digital tyre inflator at Rs 1,399 that plugs into your car socket.
- Its headline feature is auto-cut: set the target PSI, press start, and it stops itself at that number.
- It delivers up to 150 PSI and 35 L/min, with a 4m cable long enough to reach the spare in the boot.
- Best for car and SUV owners who want accurate, hands-off top-ups at home; not for those who need a cordless carry-anywhere pump.
If you have ever pulled up to a fuel-pump air machine that is out of order, or squinted at a foam-tipped analogue gauge and simply guessed, the Autofy Sonic is built to end that small daily frustration. It is a corded digital tyre inflator with one genuinely useful trick: set your PSI, and it cuts off on its own.
The auto-cut digital gauge is the whole point
At the centre of the Autofy Sonic is a backlit digital gauge with true auto-cut. You dial in the pressure your car needs, press start, and the pump stops itself the moment the tyre reaches that number. No standing there watching a wobbly needle, no over-inflating, no guesswork. For most people this is the difference between a device you actually use every fortnight and one that stays in the boot.
The motor is rated at 150 PSI maximum with 35 litres per minute of airflow, driven by a copper-coil motor and a 22mm metal cylinder rather than the thin plastic barrels you find on the cheapest pumps. That metal cylinder matters: it handles heat better on longer runs, so topping up four tyres in one go does not cook the unit. In everyday terms, a car tyre from a slightly soft 28 PSI back up to 33 PSI takes well under a couple of minutes.
The 4m power cable is longer than most, and that is deliberate: it comfortably reaches the spare wheel in the boot, which is exactly the tyre people forget and the one you least want to change on the roadside with no air in it. A built-in LED helps for those unplanned night-time top-ups, and silicone anti-vibration feet keep the compressor from walking across the ground while it runs. If you want the same reach in a simpler, gauge-first design, the AIR+ digital tyre inflator is the closest sibling in the range.
Where does it sit against its stablemates? If you sometimes air up away from the car, the AirBit dual-power inflator adds a battery so you are not tethered to the 12V socket, while the OPTIMUS tyre inflator is the no-frills 12V option if you do not need the digital auto-cut at all. Owners who also worry about a dead battery on cold mornings often pair an inflator with the VoltX jump starter, which bundles a pump with jump-start power in one box.

Who should buy it, and who should not
The Sonic is an easy recommendation for car and SUV owners who want accurate, hands-off top-ups at home or in the office car park, and who are happy to run it off the 12V socket. If you are the sort who checks pressures before a long weekend drive, the auto-cut alone earns its keep.
It is less ideal if you specifically want a pump you can toss in a backpack for a bicycle at the park, or air up a motorcycle far from any car. For that freedom you would look at a battery unit like the Bolt 5-in-1 vacuum and inflator, which also doubles as a vacuum. And if your real weekend project is a clean cabin rather than tyres, a cordless car vacuum is a different tool for a different chore.
Why correct pressure is worth the two minutes
This is not just tidiness. Under-inflated tyres flex more, run hotter and wear out faster, and they quietly cost you fuel because the engine works harder to overcome the extra rolling resistance. Keeping tyres at the pressure printed on your door sill can noticeably help mileage over a month of city driving. Correct pressure also keeps the contact patch and sidewall behaving as designed, which means shorter, more predictable braking and steadier handling in an emergency swerve. A two-minute top-up is cheap insurance.
Want the auto-cut convenience for yourself? The Autofy Sonic Auto-Cut Digital Tyre Inflator is in stock at Rs 1,399, and it ships with the 4m cable, digital gauge and LED as standard.
The one honest limitation
Stated plainly: the Sonic is a corded 12V unit that plugs into the car socket, so it is not a cordless or battery inflator you can carry away from the vehicle. If your use case is a bicycle at the park, a football, or a two-wheeler parked far from any 12V outlet, this is not the tool for that job, and no amount of good specs changes it. Buy it as a car-and-home inflator, which is exactly what it is built to be.
