Powerplus POWX1700

Everything is made of thin plastic, including the battery and charger. The battery didn't even slide all the way into the charger so it didn't make good contact. There are also 3 valves included for pumping things up, of course. 1 for air mattresses, 1 for toy balls and another for bicycle tires. I actually bought this for my bike but my tire has a Presta valve (the thin valve that is on most tires) and this is not included with the 3 valves. Only one for Schrader valves. (which is a larger type of valve) If you have to add 3 valves, why not add one for a different type of tire. Now I have to order this Schrader valve for around 8 euros because it is not included. Instead, I bought a bicycle pump for less money and which is even faster than this unit according to forums. And because everything is plastic it is very light so it always falls over when you try to attach it to something and with this quality it won't take long to break.

Super convenient to use over all

Tire pressure engine must be 2.9 bar at the back no problem for Powerplus only Pressure gauge not clean after check with tire pressure gauge
