The compressor works so far, so good, but the hose is quite short and is located at the end of the straight port valve that allows you to dock Around directly to a car-valve per press the button and lever.
So you can not connect a separate air hose or a calibrated tire inflator.
If the seal rubber sometime over, it is also difficult because nothing is interchangeable.
But biggest shortcoming is the print ad. Completely inaccurate!
The classification starts right with 1 bar, then 1.5, then 2, 2.5, 3 to 20 bar. Would she show at least halfway correct, it would not be so bad, but it understates duly what is dangerous!
I measured it with an external pressure gauge. When the compressor is 3.5 bar indicated I had real 2.5 bar in the tires.
But let's be fair: Because of the price you have probably simply accept, or just spend more money on a compressor and a tire inflator - this one gets from about 90 euros. How should this multi-device keep up? It's obvious that you compromise in this battle prices.
My solution: I attach to an external pressure gauge and select my need pressures with a fine CD markers in the appropriate places for the future.
There is now even a jump start doing that I have just used my Honda Helix CN250. He stood for a few weeks and did not want to start. Flux clamped the jump start, wait a few minutes and then I was able to restart the scooter properly. It should be noted that the terminals are very large and I had problems to attach the positive terminal on the battery. The cables may have somewhat short. The goal was achieved but, scooter runs.
Class are the 3 12V sockets, which help me to connect Miscellaneous Car Accessories and use.
Air adapter and 12V charger for the battery fit into a storage compartment, in which the air tube is placed under. Stupid: every time I want to examine air, I noticed out of these things, because you never can lay by the door the air hose. For that, I'm going to mill a recess itself ....
The lamps are incandescent lamps such as those found in car-interior lighting. I bought for a few Euros LED models that can be safely shine much longer.
All in all, this type of device so buy with those compromises that you have to go through the competitive price.
