Matt,
So sorry to hear that your experience wasn't smooth. The paddlboard adapter is really simple: just attach the end of the single tire air hose that came with your compressor (the end that would attach to the vehicle tire valve stem) to the schrader valve on the paddleboard adapter. The other end of the paddleboard adapter then goes into your inflatable. Please let us know if this helps! In the future, don't hestitate to reach out to us at sales@thorslightning.com and we would be happy to walk you through the process personally.
Thanks,
Elias Brown
