I've always carried one of these as we camp a lot and cycle miles... it's kind of a must have in the rucksacks or car and when the last one broke I thought I would struggle to find one that was as good as what we had
this one although a little more expensive had great reviews and was perfect in every way for our needs .. these are infact A very handy tool to have because of its multiple uses . Normal tyre inflators need to be connected to a power source and the car engine running for use . This one has a powerful power bank of its own so simply connect to the tyre of your car set the pressure and push the button to reach the desired pressure . Can be used to inflate cycle tyres, football and even small toys . Very useful, recommend this! Great peace of mind and can get you out of sticky situations
