Skight Tire Inflator Review: Portable, Powerful, and Cord-Free

Availability update (July 2026): The Skight inflator I originally reviewed is no longer available. I’ve since tested the OlarHike Tire Inflator Portable Air Compressor, which has all the same great specs, and it’s the one I now recommend. Everything in this review still holds; the buy links below point to the OlarHike.

Tire pressure isn’t glamorous, but it matters. Underinflated tires wear out faster, hurt your fuel economy by adding rolling resistance, and (in the worst case) fail when you least want them to. The trouble is that the usual ways to fix it are all faintly irritating.

A traditional 12V inflator means running a cord from your cigarette-lighter socket, which usually means leaving the car idling for power. The gas-station air pump is a coin toss: half the time it’s out of order, jammed, or reads wildly wrong. And a foot pump is fine until you actually have to use one.

The Skight Tire Inflator sets out to delete all of that friction. It’s a cordless, battery-powered air compressor small enough to live in your glove box, and it does the one job most of us actually need: getting a tire back to the right pressure quickly, anywhere, without ceremony.

The headline number is a 160 PSI motor pushing 32 liters of air a minute, and in practice that translates to genuinely quick inflation. Skight rates it at six minutes to take a 205/55 R16 car tire from flat (0) to 36 PSI, and about one minute to top one off from 29 to 36 PSI. In my own testing, the from-empty run came in right around that six-minute mark. And honestly, going from empty to full is the rare case. The everyday job is a quick top-off, and that’s where the one-minute figure really lands.

Where it earns its keep, though, is the cordless design. A 7500mAh rechargeable battery gives you up to 40 minutes of continuous inflation per charge (easily enough for all four tires with room to spare) and it recharges over the same USB-C cable as your phone, hitting 80% in about an hour.

No cords, no idling engine, no leaving the driveway. It made tire maintenance a thing I actually do, not a thing I avoid.

That last point is bigger than it sounds. Plenty of inflators force you to run the car for power, which means unnecessary idling, wasted fuel, and needless wear on the engine every time you check your pressure. With the Skight running off its own battery, you just grab it and go.

Getting tires to the correct pressure matters as much as getting air in them, and the Skight handles this with a clear LCD that shows two numbers at once: your current pressure and the target you’ve set. Dial in 36, walk it down to the tire, squeeze the trigger, and the inflator stops itself the moment it hits the number. No over-inflation, no babysitting the gauge.

A few touches round it out and make it more useful than a one-trick pump:

• Built-in LED light for changing or topping off a tire on a dark roadside or in a dim garage. Small thing, big difference at 9pm on a shoulder.
• USB output / power bank: the battery can charge your phone in a pinch, which is exactly the kind of backup you want on a road trip.
• Heat-resistant tube and quieter motor: it stays manageable to hold and isn’t ear-splitting during longer sessions, which cheaper inflators rarely manage.

This is the part that surprised me. The Skight has five preset modes (car, motorcycle, bicycle, and ball, plus a manual mode) and the manual mode goes all the way up to 160 PSI for high-pressure road-bike tires or specialized gear. One device covers the car in the driveway, the kids’ bikes, and the deflated basketball in the garage.

It ships with a small kit of adapters so it actually fits all of that:

• Presta valve adapter for road-bike tires with the narrow Presta valves.
• Ball needle for basketballs, soccer balls, volleyballs.
• Long tapered nozzle for pool toys, beach balls, larger inflatables.
• Air cushion nozzle for air mattresses and inflatable furniture.

It’s not magic, and I’d rather be straight with you than oversell it. Two things are worth knowing before you buy.

First, the battery. Forty minutes of runtime is plenty for a top-off, but if you’re inflating from completely flat across several tires, you’ll work through a good chunk of the charge, and a full recharge takes time. Heavy or back-to-back use means planning around the battery a little.

Second, this is an everyday inflator. With a 160 PSI ceiling it’s perfect for cars, motorcycles, bikes, and sports gear, but it’s not built for large or heavy-duty truck tires or anything industrial that needs extreme pressure or volume. Know what you’re inflating and it’ll never let you down. Ask it to do a job it isn’t sized for and it’ll struggle.

For the way most of us actually use a tire inflator (quick top-offs, the occasional flat, a bike tire here and a basketball there) the Skight is hard to beat. It’s fast, it’s genuinely cordless, the auto shut-off takes the guesswork out, and it’s small enough that there’s no excuse not to keep it in the car.

The personal-testimonial version is shorter: I used to avoid this chore, and now I don’t. That alone earned it a permanent spot in my glove box. If you want a reliable, multi-purpose inflator that lives in your car and just works, this is an easy one to recommend.

One update to that verdict: the Skight itself has since been discontinued. Its like-for-like replacement is the OlarHike Tire Inflator Portable Air Compressor, which has all the same great specs and is the one I’ve tested and now recommend. That’s where the button below takes you.

Is the Skight inflator still available? No. Since this review was first published, the Skight has been discontinued. I’ve tested the OlarHike Tire Inflator Portable Air Compressor as its replacement. It has all the same great specs, and the buy links in this review now point to it.

How fast can it inflate a car tire? About six minutes to take a 205/55 R16 tire from flat (0) to 36 PSI, and roughly one minute to top one off from 29 to 36 PSI, which is the job you’ll actually do most of the time.

Is it truly portable? Yes. It’s pocket-sized, lightweight, and fully cordless, so it slips into a glove box or backpack. There’s no compressor base or hose reel to lug around.

Can I use it on bike tires or sports balls? Absolutely. It has preset modes for cars, motorcycles, bikes, and balls, plus a manual mode up to 160 PSI for high-pressure road-bike tires. It ships with Presta, ball-needle, and inflatable nozzles to match.

How accurate is the pressure reading, and will it over-inflate? The LCD shows your current pressure and your preset target side by side, and a high-precision sensor drives an automatic shut-off that stops the moment the tire hits your number, so over-inflation isn’t really a worry.

How long does the battery last and how do I charge it? The built-in 7500mAh battery gives up to 40 minutes of continuous inflation per charge, enough for multiple tires. You recharge it over a standard USB-C cable, just like your phone, reaching about 80% in an hour.

Can I use it at night? Yes. It has a built-in LED light, which is exactly what you want for a roadside top-off or a dark garage.

Does it really work without being plugged in? It does. It runs entirely off its rechargeable battery, so you don’t need your car running or a wall outlet anywhere nearby.

Can it charge my phone? Yes. It has a USB output and doubles as an emergency power bank for a phone or other small device, a handy backup on long trips.

Is it suitable for heavy-duty or truck tires? Not really. With a 160 PSI ceiling it’s ideal for cars, motorcycles, and bikes, but it’s not the tool for large heavy-duty truck tires or industrial equipment that needs extreme pressure.
