I have purchased the device for our fleet (7 bikes, 1 trailer) to no longer pump by hand. The device is ideal in terms of size, handiness and operation. However, there are also points of criticism: Due to the compact design, the device takes a relatively long time to inflate a bicycle tire to 3-4 bar. Accordingly, the battery is almost empty after 6-7 tires. The air hose is quite short. And the adapter for Presta valves lacks a retaining clip, which presses the connection on the valve and holds it in position.
Ideal for checking and re-inflating car, motorbike and bicycle wheels. Which is my case. Depending on the terrain you're riding on, it's better to deflate your tyres a little. Back on the road, this space-saving inflator resets my tyres to the correct pressures. It's small and light and super handy for re-inflating your bike in the event of a puncture.
