Vastar Portable Air Compressor internal battery pack.
I have been using a old 12v cigarette lighter powered compressor for a while and its been ok, but having to keep unwrapping the power lead and have a power unit to plug it into is a real pain, and let’s face it these older style units are also rather bulky, so that’s where this Vastar Portable Air Compressor comes into its own, it’s a tiny self contained unit thats has a rechargeable battery back that can inflate 6-8 tyres before needing to be recharged again, it also comes with everything you need to pump your tyres up, and even the tube to the tyres is built in so one compact device thats can pack away under your seat is all your going to need now.
First thoughts was would this really work, would it have enough power to pump a motorcycle tyre, and would it do it without any issues, and yes to it all. Its one amazing item thats works as it said it would, easy to install, and what every better over my old system is it doesn’t lose any air when connecting or disconnecting it from your value, that plus it read the tyre pressure and then pumps your tyre up to the preset pressure without needing to look at the unit or stop it, as its turns itself off when it hits your preset psi, and it does it real quick too even compared to the older 12v pump. This really is a must have back up system along with a decent puncher repair kit means you won’t get stranded if you get that nail or screw in your tyre on them rides anymore.
Well worth the money and really does work so well, perfect just to check tyre pressure let along pumping tyres up. A one complete setup for your pumping needs 
Battery life is great too, I am always concern that it looks a great system but leaving it unused for a month and you go to use it and the battery dead, NOPE!!!! still showing full charge after a couple of month not being used, so well happy this way.
