If you are an avid cyclist, having the right tire pressure is a must. Finally switched from a hand pump to a 20v Dewalt pump that has digital gauges and shuts off at a certain pressure. To complement this pump I needed a proper stem mount so I bought one and it attached easily to the pump and allowed for very quick attachment to the bar stem. I also use the same to pressurize my car. This is a must-have arrangement in our house. Even my wife loves the thing, and now there's no problem inflating the tires of any bike before a ride.
