There are some things in life that you should just automatically have. One of those is a portable air compressor to throw in the trunk of your car. This is one of those purchases that you will probably never need. If you do, however, having one handy will be priceless.
Given how inexpensive they are, there is really no excuse not to have one, or even one in every vehicle you own. Finding yourself with a flat tire in the middle of nowhere at midnight is no way to spend an evening. With one of these, you won’t have to.
Simply plug it in to your car’s cigarette lighter or power supply port. It turns on automatically. You inflate your tire, throw it back in the trunk, and give thanks that you were smart enough to have one on hand when you really needed it.
