GOOLOO GT150 Review: 150 PSI Car Tire Inflator
The GOOLOO GT150 is a battery-powered portable tire inflator rated to 150 PSI, with a 7500mAh battery, 5 preset modes, and auto shut-off. It's best for cars and smaller tires; owners say it struggles and can overheat on bigger tires.
GOOLOO GT150 at a glance
The GOOLOO GT150 is a battery-powered portable tire inflator with a 150 PSI maximum pressure rating, a 7500mAh rechargeable battery, and a built-in pressure gauge with auto shut-off. It's listed at $39.99 (historical low $39.99; list price $209.98) and holds a 4.6 rating across 426 ratings.
If you're shopping for a cordless inflator for car tires, the GT150 is aimed at that job. Owner feedback consistently says it works best for cars and smaller tires, and that bigger tires can be a struggle — one owner notes it 'struggles with and can overheat' on larger tires. That's the main split to weigh before buying.

Owner voices
Short takes from public retail reviews — paraphrased or translated when long or non-English; meaning kept close to the original.
“5/5 — I think something like this is a must have for long trips. I got this so I could have an easy-to-use air pump for my truck. I have the ones that you plug into the truck power port, but those are not very conveni…”
“5/5 — Gooloo is a company I have come to trust after a couple of years of using their Jump Starter packs 9which are awesome) so when they announced this product my Ryobi inflator had just given up the ghost so I made…”
“5/5 — This thing is great. While it works best for cars and smaller tires, bigger tires it struggles with and can overheat. But there have been times where I’ve aired up tractor tires and ATV tires with it when there…”
Fill speed and pressure control
GOOLOO rates the GT150 to inflate a Tesla Model 3/Y tire from 30 PSI to 36 PSI in 75 seconds. That's a 6 PSI top-up, which is the kind of job this class of inflator handles well.
Max pressure is 150 PSI, and the unit has a built-in pressure gauge with pressure preselection. When it reaches your set PSI, it stops automatically. One owner describes it as 'so handy and so accurate' and says it 'will shut off at the perfect pressure.' Another owner frames the same feature as a limitation: 'auto shut-off limits usage.' If you want to top off a tire and walk away, the auto-off is the point. If you want to babysit a long fill, it isn't.
Battery, run time, and heat
The GT150 runs on a 7500mAh rechargeable battery. GOOLOO claims up to 45 minutes of continuous inflation per charge, or up to 4 car tires or 19 motorcycle tires before recharging.
Heat is the recurring caveat in owner reviews. GOOLOO says the GT150 uses heat dissipation technology to stay cool during extended sessions, but one long-term owner reports that on bigger tires it 'can overheat.' Treat the 45-minute figure as a ceiling for light-duty use, not a promise for back-to-back truck tires.
Modes, display, and noise
There are 5 preset inflation modes — car, motorcycle, bicycle, ball, and a custom mode — plus 4 units (PSI, KPA, BAR, KG/CM²). Mode selection is one click, which matters if you're switching between a car tire and a bike tire in the same session.
The display is an ultra-bright LED with high-contrast font, intended to stay readable in direct sunlight. Noise is listed at 92 dB, which is loud enough that you'll notice it in a garage or driveway. One owner calls it 'fairly quiet,' so expectations vary — 92 dB is the spec to go by.
Cars vs trucks: what owners say
The clearest pattern in owner feedback is size. The GT150 is repeatedly described as best for cars and smaller tires. A 2-year owner writes that it 'works best for cars and smaller tires, bigger tires it struggles with and can overheat,' while still noting it has aired up tractor and ATV tires when no compressor was available.
Another owner says it's 'best for touching up tire pressure rather than fully inflating a complete set of vehicle tires.' That's the honest use case: maintaining pressure on a car, topping up a bike or ball, and handling the occasional emergency — not replacing a shop compressor for a truck fleet.
3-in-1 extras: power bank and light
Beyond inflation, the GT150 doubles as a portable power bank and an emergency LED light. One owner who has used it heavily for over two years calls it 'great for charging my phone when I have no power around.' If you already carry a jump starter or power bank, this overlaps; if you don't, it's a real second job for the battery.
Verdict
At $39.99 with a 4.6 rating from 426 ratings, the GOOLOO GT150 is a sensible pick if your main job is car tires, bike tires, balls, and pressure top-ups. The 150 PSI ceiling, 75-second 30-to-36 PSI claim, 7500mAh battery, and auto shut-off line up with that use.
If you're inflating truck or tractor tires regularly, owner reports of struggling and overheating on bigger tires are the reason to look at a higher-duty inflator instead. The GT150 can do it in a pinch; it isn't built for it as a habit.
