How the points were given
Each inflator is scored on performance, build, value, safety and warranty, with the weights published on the method page. Safety points come from stated protective features, such as auto shut-off at a preset pressure. A factor the listing does not state scores zero, which is why the two title-only picks score zero for safety and warranty.
| Product | Shop Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| AstroAI 160 PSI | 9.7 | 30 | 21 | 21 | 7 | 3 |
| FUPYG 150 PSI | 9.6 | 29 | 20 | 21 | 7 | 0 |
| AstroAI L7 2-Pack | 9.6 | 28 | 19 | 22 | 7 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
What the listings tell you
Three listings state a max pressure figure, 150 PSI or 160 PSI, and two give no specs beyond the title. One listing states a 2 Year Manufacturer warranty; the rest state no warranty term. Two listings state dual power, battery plus 12V DC, while the two-pack pick charges by USB cord. Tire counts per charge use different tire sizes across listings, so those counts are not head-to-head figures.
Buying guide: a cordless tire inflator for car tires
Max pressure
Car tires in these listings are topped up from 30 to 36 PSI or from 30 to 35 PSI, well under the stated 150 PSI or 160 PSI maximums. Max pressure matters more for headroom than for daily top-ups. The L7 listing notes it is incompatible with heavy-duty tires, so match the pick to the tires in the garage.
Battery and backup power
The 160 PSI pick runs on a 20V rechargeable battery with a 12V DC vehicle adapter as backup, and the FUPYG pick runs cordless or on 12V DC through an 11-foot car cable. The L7 pair charges by USB cord and doubles as backup power for phones through USB-C and USB ports. A full charge on the FUPYG pick takes approximately 3 to 4 hours, the only charge time stated here.
Auto shut-off and gauge
Every full-data pick stops at a preset pressure: set the target, start the pump and it stops on its own, which guards against overinflation. The L7 gauge shows PSI, Bar, kPa and kg/cm², while the 160 PSI pick shows PSI, BAR and KPA on an LCD display. The FUPYG listing states a large digital display without naming its units.
What rides in the box
The 160 PSI pick includes a storage bag and nozzle adapters for cars, SUVs, motorcycles, bicycles, sports balls and inflatables. The FUPYG pick includes a storage bag, an air hose, schrader and presta valves, a ball and swim ring needle, a USB A-C cable, an 11-foot DC car cable and a manual. The L7 two-pack ships two inflators, two nozzles, two needle valve adapters, two presta to schrader adapters, two quick connectors, two USB charging cords and one manual.
Tires per charge
Per-charge counts differ because the tire sizes differ: up to 4 standard vehicle tires for the 160 PSI pick, 2 car tires plus 25 bicycle tires or 60 balls for the FUPYG pick, and up to 8 tires of size 195/65R15 for the L7 pick. Read the tire size behind each count before comparing counts across picks.

Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
Garage Fit Check
- Each L7 unit weighs less than 1 pound and stores in a car, on a bike rack or in a backpack, per the listing.
- The 160 PSI pick measures 6.69 inches x 3.15 inches x 9.45 inches and comes with a storage bag.
- For backup power, the 160 PSI and FUPYG picks take 12V DC, and the FUPYG car cable runs 11 feet.
- Check the box before the first job: the L7 two-pack ships two of each adapter and cord, with one manual.
FAQ: garage tools
What is a good tire inflator?
One that matches car tires: cordless power, a preset gauge and auto shut-off at the set pressure. The three full-data picks here offer 150 PSI or 160 PSI maximums, preset modes and auto shut-off, with battery or dual power for home and road use.
How many car tires can one charge fill?
It depends on the tire size behind the count. The 160 PSI pick states up to 4 standard vehicle tires, the FUPYG pick states 2 car tires, and the L7 pick states up to 8 tires of size 195/65R15, each from 30 to 36 PSI except the FUPYG count, which the listing gives without a pressure range.
Can a cordless inflator fill a tire from flat?
No listing here states a flat-to-full figure. The listings describe top-ups from 30 to 36 PSI or from 30 to 35 PSI, so treat these picks as top-up tools for car tires, not as flat-tire recovery pumps.
Do these inflators need a car power outlet?
No for cordless use. The 160 PSI and FUPYG picks also accept 12V DC as backup power, while the L7 pair charges by USB cord and needs no car outlet at all.
What pressure units do the gauges show?
The L7 gauge shows PSI, Bar, kPa and kg/cm², and the 160 PSI pick shows PSI, BAR and KPA. The FUPYG listing states a large digital display without naming its units.
