Review: Works as it should - used for powering router - Works exactly as it should. We use this to power a router that we have onboard our boat in order to access WiFi. This powers the router without issue and can even be done off a battery bank for remote use! Only gripe is that this has a very quiet hum, but that is only noticeable when you go to sleep and it's right by your head!
Review: Works flawlessly! - Amazing product, very simple and with good quality. Don’t got for cheaper alternatives to switch your led strips (single colour) they will end up flickering. This one solved my problem.
