Despite how easy it is to use the compressed air machine available at your local gas station, too many people are still riding around on underinflated tires. According to TireRack.com, "If a vehicle's tires are under-inflated by only 6 psi ... the tire's tread life could be reduced by as much as 25%." Luckily, it's more affordable than ever to get your own portable air compressor and fill your tires in your very own driveway. There are options now with built-in flashlights, bike tire and sports attachments, and more. Starting at under $30, these could save you a trip to the gas station for a top-off or a call to AAA for a tow. Thermoforming Machine Automatic
The VacLife tire inflator plugs into your car's 12V power outlet with an 11.9-foot power cord to get its juice. It has automatic shutoff capability once it hits your preset PSI level, a built-in LED flashlight, and comes with three additional nozzles for inflatables like sports equipment, bike tires and more. This one is a great budget option but won't work for large vehicles with tire pressure greater than 50 psi or tire width greater than 245 mm like some trucks and off-road vehicles.
The FORTEM air compressor stores its 14-foot power cable within itself, making it super portable. The cable itself plugs right into your car's cigarette lighter port. This inflator comes with multiple attachments for car and bike tires, inflatable toys and more, and has a built-in LED flashlight. Like many others, the FORTEM has automatic shutoff functionality and allows you to set your desired PSI before starting your inflation. It even comes with a 1-year warranty!

The EPAuto air compressor is one of the most popular options out there. It plugs into your car's 12-volt lighter socket, comes with additional valve adapters for things like basketballs, inflatables, etc., features an automatic shutoff and has a built-in LED flashlight, like so many others. Also, like many of the more portable tire inflator options, this one isn't recommended for trucks or larger vehicles. Be aware that this air compressor actually has the shortest power cord on our list, clocked at only about 9 feet by a helpful answerer in Amazon's Q&A section, so if you like a little more slack, this might not be the best choice for you.
The TEROMAS tire inflator is a great choice because it can plug into your car's 12-volt cigarette lighter plug or a 110/120-volt wall outlet. It can inflate a P195/65R15 tire from 0 to 35 psi in under 4 minutes. The auto-off function automatically turns off the pump once it reaches your desired preset pressure value. This compressor, like many, has a digital display that conveniently shows your tire's current pressure and a built-in LED flashlight. It comes with three additional adapters and can be used with cars, motorcycles, bikes, air mattresses, balls and more. Learn more here.
This Avid Power tire inflator is a multi-purpose cordless pump that can be used with most tires, inflatable sports balls and more. It's a little more expensive than the others on our list, but it's also a little more convenient, since it doesn't need to be plugged in. If its battery pack happens to be out of juice when you need it, it also comes with a 12-volt power adapter that can be used to plug it in. The compressor has an automatic stop function with an indicated pressure accuracy of +/- 1 psi, a built-in LED light and comes with its very own tool bag. Be aware that this compressor, like many others, isn't suitable for large truck tires.

A portable air compressor is a device that can be stored in your trunk and can be used to add compressed air to your tires, sports balls, pool accessories and more.
A huge number of Americans drive around with under-inflated tires. In fact, according to NBC News, up to 32% of vehicles are driving around with at least one tire under-inflated. This can be, at best, bad for your gas mileage and at worst, dangerous. Keeping a portable air compressor in your trunk can remove the barrier of hunting down a compressor at the gas station and help people to keep their tires inflated more easily, with less stress.
There are different types of personal air compressors for tires, but the choices in our list work by simply plugging them into the cigarette lighter port in your car and using that power to create air pressure sufficient enough to inflate a tire.
Most of the best portable air compressors are dead simple to use. Just plug it in, make sure you’re using the right attachment nozzle, attach it to your tire’s air valve and begin pumping air into your tire.
Depending on how much power you’ll need, the cost of air compressors can vary significantly. For the options on our list, and others like them, you’re probably looking at a cost around $30 to $100.
The main benefit of traveling with a portable air compressor is being able to top off your tires at a moment’s notice. It may take up trunk space that could otherwise be used for other things, but in our opinion the trade off is worth it for peace of mind and safety.
