Best Portable Air Compressor

What happens if you’re in the middle of an off-road adventure and get a flat tire? You might not have a phone signal - and if you do, it could be hours before help arrives. 

A portable air compressor is a perfect solution in this situation. Below, we’ve got a guide to the best portable air compressors for overland adventures. Check each of them out, paying close attention to the pros and cons! 

What is a portable air compressor & why do you need one?

A portable air compressor is a device that can pump pressurized air into various tools and objects. They’re commonly used on building sites to power drills and other pneumatic devices. However, you can also use one to pump up a deflated tire in an instant. 

Will you need a portable air compressor? That depends, do you go on many off-road trips where you’re driving overland? If so, there’s a big chance you’ll end up with a flat tire after going over rough terrain.

More to the point, off-roading requires a different level of tire pressure than traveling on a proper road. Typically, you want to reduce your tire pressure slightly when overlanding to help the suspension and offer a more comfortable ride. Then, when you get back on a smooth road, you need to inflate the tires back up to their regular pressure. 

This is where a portable air compressor really comes in handy. It lets you get the optimal tire pressure depending on the terrain you’re driving on. So, even if your tires don’t go flat, you could still use one of these devices throughout your trip.
