Blew the fuse for my car charger port
Reviewed in Australia on 27 September 2019
Worked well for a couple of months, then the car's fuse for the charge port blew. Went through another two fuses testing things out and it was definitely this that did it. The last time some smoke came out of the port. Replaced the fuse again, everything else I plug in works fine.
Edit: The company sent me a replacement for free (didn't even have to contact them). So, it was possibly just a single faulty one, which they'd replace. I haven't used the new one, just in case, but that might add some peace of mind.
