Have you ever been driving down the road and noticed a strange, gravelly sound coming from the back of your car?

Maybe passing cars began to honk at you. Perhaps you even heard a loud pop and lost a little control over your vehicle for a second before you knew what was going on.

When these things occur, the most likely culprit is a low or blown car tire.

Changing your tire isn’t a complicated process with the right tools, though it can be tedious and frustrating, especially if you get caught in the rain or in terrible traffic.

But too often, drivers open their trunks to retrieve their spare tire, only to find that the spare is entirely flat. And those with low tire pressure may be many miles away from a mechanic or a gas station with an air pump.

Before you have to spend a small fortune on a tow truck or new tire the next time your car has a flat, consider investing in a portable air pump ahead of time instead.

There are a wide variety of gadgets for your car, and you now have the power to jump-start your battery with something that fits in the palm of your hand. The same is true for the air in your tires.

Using a small handheld device (whether a cordless compressor or a portable compressor that you plug into an outlet in your car), you can put the needed pressure in your car’s tires (assume you didn’t actually have a blow out) and get yourself to the nearest tire shop or gas station.

In a bind, you can easily use a portable tire inflator to add some needed air before heading to the nearest mechanic. A portable air inflator is normally powered via your vehicle’s 12V cigarette lighter socket or outlet and considering the amount of trouble, labor, and money they can save you, they’re incredibly inexpensive.

Today, we’re going to take a comprehensive look at portable air pumps and find out which model is the best. Let’s get started!

Before we can compare products, we must first answer the basic questions regarding air pumps. It would be hard to tell which the best portable air pump for car tires if we didn’t know what a portable air pump was!

How Does A Portable Compressor Work?

Air pumps are firstly connected to an electrical outlet and receive energy through this connection. This electrical energy travels into the heart of the air pump, powering the motor. The motor mostly sucks air in from an opening and pushes that same air outward a higher pressure through a separate opening.

Portable air pumps typically rely on the power generated by your car battery to function.

Nozzle attachments allow the user to inflate many various inflatable items, no matter the size of the air pump.
