Like many of you that has purchased products directly from the country of origin, you have probably laughed, cried, threw up your hands, sent it back or just figured it out on your own. In some cases, going back to the company for information or returning it is your only options. Here is my story:
I purchased this product with a lot of hesitancy as the descriptions and on-line comments were mixed at best. At approximately $115, I decided to give it a shot. SO, the product showed up as pictured, however the installation materials showed up in a single bag of loose parts. No, bill of material, no wiring schematic, no diagrams. Some parts were oversized, undersized, not even intended for this product or just plain not there. I could do an entire write up on just what was wrong, but if you bought one, you already know most of that.
The product was advertised as an air compressor that could be installed on a vehicle with the intent to air up vehicle tires when needed after 4×4 off-road excursions. However, passed the marketing comments in the advertisements, there was little (none) information on how to apply/install the product properly in a vehicle. Looking at the 6-page document, it was obvious there was a lot of cutting & pasting from other product documents to assemble this manual as there are several instructional items that just don’t match the product provided.
Listed below reflects VEVOR’s entire installation and operational instructions.
INSTALLATION: The AIR compressor is designed for mobile, portable operation. Place the unit on the ground next to your vehicle, there is no requirement to permanently install or remove from the supplied box. Do not operate the unit with the box closed as this will limit air flow and may result in overheating.
OPERATION: Switch power switch to ‘on’ position. Compressor will cycle on and pressurize the inbuilt receiver tank. Adjust the pressure regulator to the desired outlet air pressure requirement. Connect and disconnect air lines as necessary to begin operation. The compressor will automatically start and stop based on demand.
I approached VEVOR both online and over the phone multiple times for additional information to use the product as advertised, but never got anywhere. However, I was asked multiple times by VEVOR tech support to provide detailed information on what was needed. When they replied “show us pictures of what is missing” I knew there was no reason to go any further.
I told them, I had no intention of providing engineering documentation (for free) to correct all their errors and omissions on the product. At the time, I estimated 20 hours of engineering and testing time. They did not respond to my offer other than not responding at all. When I attempted to return the product for a full refund, they would not provide me a full refund as I would not give them details on what was missing. They offered me $31 for my troubles and I could just keep the product. I took it just to close the dialog and use the money for installation parts needed to make the product functional.
(Teaser) Honestly, I think the air compressor will work as needed with changes in some of the installation parts provided. Before installing this on my vehicle, I bench tested the product with my solutions applied to make sure that it ran without issues and performed safely as I expected.
So, if you have purchased this product and want to install it as an onboard unit, but not totally sure where to go or what to do, send me an email and I will answer your questions or share my solution with you. I prefer not to openly publish my solution as it will just get back to the supplier, and that defeats the purpose.
