Having a portable car tire inflator is a good idea for anyone who is often on the road. There are several reasons why a portable tire inflator is a good addition to an emergency kit. It's inexpensive, it's easy to store, and it can be used to inflate vehicle tires. It also allows you to check the pressure of your tires on a regular basis.

One of the biggest drawbacks of portable tire inflators is that they don't have a storage area for the cord. They also have a limited amount of support for different tire sizes. This means that you may not be able to inflate your tires if you have an SUV or truck. If you plan on keeping a tire inflator in your vehicle, you may want to buy a portable air compressor that can support larger tires.

You also want to make sure that you are buying an inflator that can inflate your tires to at least 100 PSI. Having low PSIs can lead to premature wear and tear, as well as hurt fuel economy. This means that you should invest in an inflator that has a pressure gauge that will show you your current pressure. Some of the newer models of portable air compressors will also have a digital display, which will provide you with more accurate readings.

Inflators that have LED lights are also very handy. They are particularly useful when you are in a dark place, and some models allow you to control the lights with an ON/OFF switch.

There are also portable air compressors that combine battery packs for jumping a stuck car. These devices are especially useful for those who spend a lot of time rescuing motorists. However, they aren't as powerful as plug-in models, and can't run as long.
