Useless Adapter for Automotive Tool

THIS adapter is a rip-off. As my tests showed, this adapter could not handle the load of my power tools, despite the seller claims .It fell well short of my expectations and ruined my experience with this product..

Pros
  • None found.
Cons
  • Not suitable for high-powered automotive tools.

Dangerous and useless. Do not use!

Terrible and very DANGEROUS. Ordered two and the first one was mislabeled: 120V input and 12V output swapped. Plugged it in, turned it on and it exploded! The second had a different label which was correct so I plugged it in, turned it on and it ran for about eight hours. I'm an electrical engineer so I know what I'm doing and it's totally useless. I would give them negative stars if I could.

Pros
  • It has the advantages of high power factor, low temperature rise, no noise, no strobe effects, etc.
Cons
  • Band
