This is the perfect emergency air compressor. First off, it comes with a sturdy storage box and the whole tool is surprisingly small. This means you can happily tuck it away into a corner of the boot until you really need it.
However, you can rest assured that when you do, it is going to perform the job. It’s incredibly simple to use for one thing. Un-box, plug the power cord into a regular 12V cigarette lighter socket. The built in LCD screen is nice and bright making it easy to operate in even low light situations.
Simply tap in the desired pressure, apply to the tire valve and press go. It even has auto cut off to avoid over inflation. One negative is a lack of an adapter to plug into a wall socket. This means the tool will always run off the cigarette lighter socket, which is not great for frequent use.
