To begin with, the instructions delivered were in German, impossible to find the instructions in French or even in English all the links were out of order, so I asked the Chinese manufacturer directly and here it is: YH-QB01 compressor manual
It's a water-cooled compressor that requires a water tank of at least 10L ... A bit boring to move but less than I thought ...
My opinion will be brief since I only have a few minutes of operation since it goes very fast for my use.
You have to follow the safety instructions and do not inflate things that may blow you in the face! Do not let the children approach it therefore!
For the rest it therefore works very well (for the moment) it has all the necessary safety features (pressure, temperature, valves) and complies with the instructions.
Please note it comes without oil, you have to buy a 1L can of ISO VG46 hydraulic oil separately (less than 10 €), it swallows about 0.6L
Before buying this one, because I didn't want to bother with a tank of water, I had tested this other red model sold for 150 € more and better rated on Amz but in comparison it is frankly a toy. . amazon notices of the kind "very well received quickly but not yet tested" no thank you !!
This compressor is an oil-free one with probably shitty reliability and with hazardous instructions (which says that you have to lubricate every X hours with grease without saying with what or the quantity see photo of the instructions below. ..) and which takes 8 times longer to load (250 W nominal VS 1800 there is no picture) ...
No thank you, returned refunded!
Addition: video test
