Been looking at the MS MultiSafer as I run two dashcams, but I remember liking this other one which displayed voltage but can't remember what it is called. Someone posted a photo of it on here but I can't find it.
Found it, the Vicovation Power Plus. But like the Power Magic Fail it's only 2A output max and I'm not sure if my two cams (will soon be two SGs) will be stressing it too much?
