Does what is supposed to i wanted to hardwire a qi charger in my vehicle and this did the trick i used an add a fuse and ran some extra cable through the carpeting and now i have a qi charger right where i always rest my phone anyways so now my phone can sit where it always sits and charge instead of just sitting there

I tested it with amp meter less than 1amp voltage 4

8 it should be 5v ive got a couple of these now one powering a qi charger in my truck and one for a raspberry pi on a 3d printer
