Best Portable Tire Inflator: DeWalt vs. NOCO vs. WORX vs. Gooloo
How fast cordless and 12-volt tire inflators fill a flat, which ones blow a 15-amp fuse, and how DeWalt, NOCO, WORX and Gooloo handle truck tires.
A portable tire inflator is the simple insurance most drivers skip until a cold morning turns on the low-pressure light. Most of them will eventually fill a tire. The differences are in how long it takes, how hot the pump runs, whether it can handle a truck tire at 60 to 80 PSI, and whether a 12-volt model will blow your car's accessory-socket fuse.
This guide covers what separates a good tire inflator from a frustrating one, and which type fits which driver: cordless power-tool inflators, plug-in 12-volt pumps and pocket-size rechargeable ones.
Quick verdict
- Best all-around: the DEWALT 20V MAX Air Inflator (DCC020IB). It runs on a DeWalt 20V battery, a 12-volt car socket or household power, ran the coolest of any pump, and its gauge matched a calibrated gauge exactly. It isn't the fastest.
- Fastest 12-volt inflator: the NOCO AIR15 Portable Tire Inflator. It filled a flat car tire in under 3 minutes, faster than every other plug-in pump, but it draws more current than many cars' accessory sockets allow.
- Best cordless kit: the WORX 20V Cordless Tire Inflator (WX092L). The fastest cordless pump in its class on both a flat car tire and a high-pressure truck tire, with the battery and charger included.
- Best compact inflator for the glovebox: the GOOLOO GT160 Tire Inflator. Under 2 pounds with a built-in battery, it tops off a tire quickly and even handled a truck tire at 80 PSI.
The tire inflators side by side

Times are for a 15-inch car tire filled from completely flat, and for adding 10 PSI to load range E and G light-truck tires. A topping-off job, a few PSI on a tire that's merely low, takes a fraction of these times. Treat the numbers as a comparison between models, not a promise for every unit.

What makes a tire inflator good
Speed claims are optimistic
Box claims like "flat to full in under 5 minutes" rarely hold up. Compact 12-volt pumps that promised 5 minutes took 7½ to 8½ minutes to fill a flat 15-inch tire; one that promised 10 took about 11½. A pump that claimed a tire in 1½ minutes needed about 3½. The fastest pumps were the big cordless power-tool inflators and the larger 12-volt units, which filled the same tire in about 2½ to 4 minutes.
Watch the fuse on 12-volt pumps
A car's accessory socket is usually fused at 15 or 20 amps, and some pumps draw more than that. The small single-cylinder pumps used about 7 to 12 amps. Dual-cylinder pumps used about 15 to 18. The NOCO AIR15 drew about 20.6 amps, well over its 15-amp rating and enough to blow a 15-amp fuse. Check the socket's fuse rating in the owner's manual before buying a fast 12-volt pump. The DeWalt drew under 10 amps on 12 volts, so it's safe on almost any vehicle.
Heat shortens a pump's life
Compressors that run hot don't last as long, and a hot air hose breaks down over time. Hose temperatures on a flat-tire fill ranged from about 84°F on the DeWalt to over 200°F on several weaker pumps. Pumps with a duty cycle, a set run time followed by a cool-down, will stop partway through a big job. One weak rechargeable pump gave up at 15 PSI after 10 minutes with its hose over 200°F.
High pressure separates the pumps
Car tires sit around 30 to 40 PSI, but many light-truck tires run 60 to 80. Some high-volume pumps that were quick on a car tire slowed way down at high pressure. The pumps that stayed fast at 70 to 80 PSI were the big cordless inflators, led by Milwaukee's M18, plus the WORX and the DeWalt. Even the pocket-size Gooloo GT160 got a truck tire from 70 to 80 PSI, slowly but without overheating.
Gauges and auto shutoff
Most built-in gauges read within about 1 PSI of a calibrated gauge, and the DeWalt's matched exactly. A few were off by 2 to 3 PSI, enough to matter on a car tire. Auto shutoff is the feature to want: set the pressure, start the pump, walk away. Some fast pumps overshoot: one shut off about 4 PSI over its target. Check the pressure with a separate gauge the first few times.
The picks in detail
DEWALT 20V MAX Air Inflator (DCC020IB): best all-around
The DeWalt is the most flexible inflator here. It runs on any DeWalt 20V MAX battery, can also run from a car's 12-volt socket, and can use household power with an AC cord sold separately. It has both a high-pressure hose for tires and a high-volume hose for air mattresses and pool floats. On 12 volts it drew under 10 amps, its hose stayed the coolest of any pump, and its gauge agreed exactly with a calibrated gauge. On battery power it filled a flat car tire in about 6½ minutes and took a truck tire from 70 to 80 PSI in 3 minutes 45 seconds.
It's slower than the fastest pumps on a car tire, it's heavy at about 5½ to 7 pounds depending on the battery, and the battery and charger aren't included. For anyone already on DeWalt batteries, it's the obvious choice.

NOCO AIR15 Portable Tire Inflator: fastest 12-volt pump
The AIR15 is a compact 12-volt inflator that was the fastest plug-in pump at everything: a flat car tire to 35 PSI in about 2 minutes 53 seconds, a truck tire from 50 to 60 PSI in about 1½ minutes, and a flat truck tire to 60 PSI in about 10¾ minutes. Its hose stayed fairly cool at about 114°F, its gauge was within half a PSI, and it shuts off on its own.
The catch is power. It drew about 20.6 amps, more than its 15-amp rating, which will blow the accessory-socket fuse on many vehicles. It's rated to 80 PSI, and at about 5¾ pounds it's heavier than it looks. Buy it if your vehicle's socket is fused at 20 amps or more.

- Vehicles with a 20-amp accessory socket
Skip it if
- Sockets fused under 20 amps (it drew about 20.6 A)
WORX 20V Cordless Tire Inflator (WX092L): best cordless kit
The WORX was the fastest cordless inflator in its class in every job. It topped off a car tire from 30 to 36 PSI in 52 seconds and filled a flat car tire in 5 minutes 52 seconds, more than a minute faster than the next pump in its class. It took a truck tire from 70 to 80 PSI in about 3½ minutes, ahead of some higher-end pumps. It has an LED work light, auto shutoff, and the WX092L kit includes a 20V battery and charger.
Its hose ran warm at about 185°F, and it's louder than the compact pumps. If you don't already own a power-tool battery platform, this is the simplest way to cordless speed.
Cordless speed, kit included
WORX 20V Cordless Tire Inflator (WX092L)
Topped off a car tire in 52 seconds and filled a flat in under 6 minutes, with a work light, auto shutoff and the battery and charger in the kit.
- 20V battery included
- LED work light
- Auto shutoff
Good for
- Cordless speed without a battery platform
- SUVs and trucks

- Quiet use (louder than the compact pumps)
GOOLOO GT160 Tire Inflator: best compact inflator
The GT160 weighs about 1.8 pounds with a built-in 7,500 mAh battery and doubles as a phone power bank. It topped off a car tire in 1 minute 15 seconds, more than twice as fast as another pocket-size pump. It filled a completely flat tire in 8 minutes 50 seconds with charge to spare and, unexpectedly for its size, took a truck tire from 70 to 80 PSI in about 7 minutes.
It runs hot on long jobs, about 195°F at the hose, so it's best for top-offs, bikes and the occasional flat rather than regular big fills.

Other inflators worth knowing about
- Milwaukee M18 inflator (2848-20). The fastest inflator of all: a car top-off in 18 seconds, a flat car tire in about 2½ minutes, and a truck tire from 70 to 80 PSI in 1 minute 40 seconds, with a cool hose throughout. It overshot the target by about 1 PSI and weighs close to 9 pounds with a battery. It's the pick for M18 owners. The Amazon listing was low on stock, so it isn't linked here.
- Makita and RIDGID 18V inflators were the next fastest cordless pumps, at about 4 minutes for a flat car tire. The Makita didn't shut off at its target and overshot by about 4 PSI. The RIDGID is loud, hops around while it runs, and its hose ran hot.
- Store-brand cordless pumps from Kobalt, Bauer and Ryobi all filled a flat car tire in about 7 to 7¾ minutes and handled truck tires well. They're good buys for anyone on those battery systems.
- Dual-cylinder 12-volt pumps are fast, about 3½ to 5 minutes for a flat car tire, but they're heavy, around 5 pounds, and draw 15 to 18 amps.
- Viair's portable 12-volt pump was second only to the NOCO for speed, but its gauge read about 3 PSI off. Use a separate gauge with it.
- Jump starters with built-in inflators are convenient, but their pumps are much slower than these. See the jump starter guide.
Fastest 12-volt pump
NOCO AIR15 Portable Tire Inflator
The fastest plug-in pump at everything: a flat car tire to 35 PSI in under 3 minutes, with a fairly cool hose and an accurate gauge.
- 12V
- Up to 80 PSI
- Auto shutoff
Good for
- Vehicles with a 20-amp accessory socket
Skip it if
- Sockets fused under 20 amps (it drew about 20.6 A)
How to choose
- Already own a power-tool battery? Buy that brand's inflator. Cordless power-tool pumps were the fastest and coolest-running.
- Want something that lives in the car? A compact rechargeable pump like the Gooloo GT160 is fine for top-offs. A 12-volt pump can't run out of battery.
- Check the fuse before buying a fast 12-volt pump. Over 15 amps can blow a 15-amp accessory fuse.
- Trucks and RVs need a pump that stays fast at 60 to 80 PSI.
- Look for auto shutoff and double-check the built-in gauge against a good handheld gauge.
Cold weather drops tire pressure, so check tires when the weather turns. For a shop compressor that also runs air tools, see the garage air compressor guide, and for a hose that reaches every tire, the retractable air hose reel guide.
Who should buy which
- Most households, and anyone with DeWalt batteries: the DeWalt DCC020IB.
- Fastest plug-in pump, on a vehicle with a 20-amp socket: the NOCO AIR15.
- Cordless speed without a battery platform: the WORX WX092L kit.
- A small pump to keep in the car: the Gooloo GT160.

Frequently asked questions
How long should a portable tire inflator take to fill a flat tire?
For a completely flat 15-inch car tire, the fastest cordless and larger 12-volt pumps take about 2½ to 4 minutes. Typical compact 12-volt pumps take 7½ to 8½ minutes, and pocket-size rechargeable pumps about 9 to 10. Topping off a tire that's only a few PSI low takes under a minute on a good pump.
Can a 12-volt tire inflator blow a fuse?
Yes. A car's accessory socket is usually fused at 15 or 20 amps. Small single-cylinder pumps draw about 7 to 12 amps, dual-cylinder pumps about 15 to 18, and the NOCO AIR15 about 20.6 amps, enough to blow a 15-amp fuse. Check the fuse rating in your owner's manual before buying a fast 12-volt pump.
Are cordless tire inflators better than 12-volt ones?
The cordless power-tool inflators were the fastest and coolest-running pumps overall, and they work anywhere. A 12-volt pump never needs charging and can live in the car. If you already own a power-tool battery system, that brand's inflator is usually the best buy.
Can a portable inflator fill a truck tire to 80 PSI?
Many can, but speed varies a lot. Adding 10 PSI to a load range E truck tire at 70 to 80 PSI took about 1 minute 40 seconds on the Milwaukee M18, about 3½ to 4 minutes on the WORX and DeWalt, and about 7 minutes on the pocket-size Gooloo GT160. Some high-volume 12-volt pumps that were quick on car tires slowed sharply at high pressure.
Are built-in tire inflator gauges accurate?
Most read within about 1 PSI of a calibrated gauge, and the DeWalt DCC020IB matched exactly. A few were 2 to 3 PSI off, and some fast pumps overshoot their set pressure. Check against a good handheld gauge the first few times you use a new inflator.
What features matter most on a tire inflator?
Auto shutoff at a preset pressure, a gauge you can trust, and a pump that doesn't overheat. Hose temperatures ranged from about 84°F to over 200°F, and hotter pumps tend to wear out sooner. For trucks, look for a pump that stays fast at 60 to 80 PSI; for a car, a compact pump that tops off quickly is enough.
