I'm curious to know what people are doing with their USB port.

After using it quite a bit, I've come to the conclusion that the Scramblers USB power is pretty weak. I think I saw that it's supposed to be 1 amp, but it's not. When I go out for a long ride and run my iPhone 6 (not the plus either) with the screen on full bright and running the Navigon GPS app, while also playing music to my bluetooth helmet kit, it cannot maintain a full charge on my iPhone. I start off with 100%, and then the phone slowly drains. By the end of a 5 hour ride a few weeks ago, it was down to about 45%. Granted if it wasn't plugged in it would have been dead, but still. I've also noticed if the screen is off and I'm not using it, it charges disappointingly slow.

Luckily I happened to have a
and never used, so I wired that in. The little clip where the wires run into the OEM USB jack is 12V, so I just tapped it there so that I wouldn't need a fuse. Yesterday I did a 245 mile ride that was about 5 hours (which was awesome), and with the new USB jack the iPhone stays charged at 100% the whole time.

I guess I'm just disappointed at how weak the OEM one is that it can't even keep my phone charged when it's in use. At least the one I had on hand did the trick.

Luckily I happened to have a 1.2A 12v hardwire kit that I got off Amazon and never used, so I wired that in.

I suspect the USB isn't really there for charging things as much as upgrading maps.... I also agree it's probably an 0.5A output regardless of what the manual says.

One problem with using phone as GPS that I found with my phone is that the battery drains so quickly with GPS on and the USB port cannot charge the phone fast enough, so basically my phone would run out of battery after about 2 hours despite the fact that it is continuously charged by USB port.
