What's great about this device is that it's portable, measuring just 6 inches long, about 4 inches wide and weighing only 1.5 pounds, so you can easily take it with you. It is powered by a lithium battery that can be charged via USB. It has an LCD screen where you can see the current tire pressure and set the desired pressure that you want the device to inflate the tire to. After inflation (when the air pressure reaches the set value), the pump will stop working automatically. It also comes with 3 adapters so you can inflate your car/bike/motorcycle/ball. And I liked the screw connection to the tire valve. Essentially no pressure loss when the pump is disconnected, unlike flip-out fittings on foot pumps. I can only say. It should be!
