Every household should have a battery powered tire inflator. In our house we have some cars, some bikes, sports balls, pool toys. They all need air.

I recently purchased the Black and Decker 20V Lithium Cordless Multi Purpose Inflator.

There is a lot to like about this product.

It uses standard 20V Lithium batteries that, which can be removed and inserted. They can be purchased cheap if you get third party brands from Amazon or your local hardware store.
It also supports AC and DC power
It will fill a car or bike tire, but also pool toys
It's light and portable
It has an easy to use PSI gauge - you set the desired PSI and auto shut off.

The item does not come with a battery or charger so I'd recommend the following (if you do no already have Black and Decker tools).

Fast Charger - not necessary if you are ok with the standard slow charger.
Battery with slow charger (this battery will also charge USB devices)
Two pack of batteries

Note: it's cheaper to buy a drill and impact driver kit than stand alone chargers and batteries. Go figure. This is what I did. These are not the nicest / highest quality drills but for small household work they are just fine and it's nice to have one battery system for both.
