This Air Pump Pocket, by Chinese tool manufacturer Hoto, fits well within the brand's designey aesthetic. Sleek and elegant, the diminutive object measures just 3.66" 2.28" 1.50" (93 58 38 mm) and weighs 0.56 lbs (255g). Small size aside, it'll inflate up to 150 PSI, and has enough oomph to fill a 55-80 PSI tire in under 30 seconds. You can program in your target PSI, and it'll automatically stop once it reaches it.And of course, you can use it for more than bike tires.The price is $60, and it gets rave reviews.
