Would this adapter work in -20 to degrees?
Hello and welcome to the forum @dan_carpenter! The supplier didn’t have that information in the documentation that I was able to review, so I have reached out to them and will update you once I have a response.
In the meantime, this is my opinion: they seem to imply that it is meant for indoor use, making it unlikely that they tested for or will be able to guarantee performance at -20 degrees. We’ll see what they say, but I’m not going to be surprised if it turns out they don’t have data on this.
