Advice on a Christmas Gift - Car Related

My son drives a lot and I want to buy him a portable rechargeable tire inflator or a combination battery booster / tire inflator for Christmas. Any suggestions? I have been Googling this and every "Top Rate" or "Best Item" is completely different. There are very few that overlap that would tell me that is really a good product.

I am hoping someone else uses these and can recommend a good one.
