## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    does what I need it to
  

*by A***R on Reviewed in the United States on February 13, 2024*

Needed an adapter to go from the 14-50R outlet to the L14-30 cable to power the new cure oven recently delivered. Seems to be working very well for this use case. Also having the cord connected to the adapter means it's not sticking directly out of the outlet (lower profile).I also have another 14-50 adapter for use with another 240v tool/item (welder plug type). It's nice knowing that I can use the other outlet if I need to run more 240v powered tools at one time. Or have something that draws more amps than can be provided to the others.
