Last night, I watched the low tire pressure sensor on my car come on (because it only ever comes on when I’m driving late at night). And while looking for a gas station that didn’t seem too creepy, I thought to myself “I really should’ve ordered that 12-volt air compressor,” as I’d much rather fill up my tires in the safety and comfort of my own driveway than at some sketchy gas station.
Not only are 12-volt air compressors great for filling tires, but there’s a host of other uses that make them worth the investment. Keep it in your garage or your vehicle for quick and easy access. I’ve compiled a list of the top 12-volt air compressors on the market along with an informative buying guide that will help ensure you get the best air compressor for your needs and that you’re not stuck paying $4 for air at the only open gas station in town at midnight.

Things to Consider Before Buying 12-Volt Air Compressors
When it comes to portable 12-volt air compressors, many people think it’s a one-size-fits-all thing and that there’s really not much to consider. While that may have been the case decades ago, it’s certainly not the lay of the land in today’s market. Today’s 12-volt air compressors come in a wide variety of sizes and functions suitable for different uses. Be sure to get the one that most suits your specific needs.
Key Features
Psi Output
The power capability of your 12-volt air compressor will be the number one key feature to pay attention to. Most decent 12-volt air compressors will have a psi rating of 100, which is just enough to inflate most regular sized car tires. For truck or SUV tires, you might need something stronger, in the range of 120 to 150 psi. For small power tools, you’ll likely want to look for a 12-volt compressor with a psi above 150.
Portability
If you’re planning on keeping your 12-volt air compressor in your trunk or the bed of your truck, you’ll want something highly portable, with a durable body or case that won’t rust or crack easily if it rolls around. If you’re looking for a compressor for your workshop or to take between job sites, you’ll want something rugged with a higher power capacity that might be somewhat less portable than just an air compressor that’s used for tire management.
Power Consumption
Since you’re likely using your car’s battery to run your 12-volt air compressor, you’ll need to be mindful of how much power it draws. You don’t want to over tax or damage your battery, so look for an air compressor that pulls about 120 watts or less.
Warranty
Consider buying a 12-volt air compressor that’s backed by a solid warranty. The best companies will offer at least a one-year warranty, but some will offer even a two- or three-year protection plan against manufacturer’s defects.
12-Volt Air Compressor Pricing
If you want a basic, straightforward 12-volt air compressor that will inflate most car tires and sporting equipment, you can get a decent model for between $30 and $80. For stronger and more powerful 12-volt air compressors that are suitable for larger tires and off-road capabilities, you’ll need to up your budget to between $120 and $200.
FAQs
You’ve got questions. The Drive has answers.
Q: How does a 12-volt air compressor work?
A: A 12-volt air compressor uses your vehicle’s battery, or any 12-volt battery, to power a motor that directly forces air into an object to inflate it to a certain pressure. Because they don’t store compressed air in the tank, they have less power and capacity to fill larger objects but are usually fine for small automobile tires, bicycle tires, and sporting equipment.
Q: How do I maintain my 12-volt air compressor?
A: To properly maintain your 12-volt air compressor, be sure to read the user’s manual that comes with the unit. Be sure to store your compressor in a protective bag or carrying case when not in use to keep it from getting scratched or damaged, or allowing dust and dirt to clog the motor and its components. Regularly inspect the hoses, valves, and power cords for any damage and replace them at the earliest sign of wear.
Q: What size compressor do I need to inflate car tires?
A: Most compact cars and sedan tires can be inflated using a 12-volt air compressor with a maximum psi output of 100. If you’re looking to inflate your truck, SUV, or RV tires, you’ll need a maximum pressure of between 120 and 150 psi.
Q: How many amps does a 12-volt air compressor draw?
A: If you have a 12-volt air compressor that plugs into your car’s cigarette lighter, the typical power draw will be between 10 and 15 amps. For a 12-volt air compressor that clips directly to a 12-volt battery, the power draw can be between 20 and 40 amps.
Q: What kind of compressor do I need for a paint gun?
A: Depending on the size and capacity of the paint gun you’re using, you will need an air compressor with a capability of pushing between six and 30 cfm. Most 12 volt air compressors that are suitable for inflating car tires are underpowered for use with a paint gun.
Q: What psi should I set my air compressor to fill tires?
A: Most average sized automobiles require a psi of between 34 and 36 to be properly inflated. This varies from car to car, however, so be sure to check your specific tires before inflating. You can usually find recommended tire pressures on either the driver's side door of your vehicle or on the side of the tires themselves.
