This is my third bike I've installed the USB power plug. It has always performed flawlessly. I opted for a Burnsmoto USB socket because it takes less space than a bulky cigarette lighter type plug AND most devices I use (GoPro cameras, GPS navigators, phones etc.) can be charged via USB. I can also use the same compact charging cable for many devices and storage it under the seat.
The 690 Enduro R has a cable for powering various devices ready and hidden behind the headlight. It us just a matter of unscrewing the two bolts on the sides of the headlight and digging the ends out. The one I used was marked ACC2 which means it's only hot when the key is turned so there is no chance of a GPS to drain the battery if left on unintentionally. (there is also a an always hot ACC1 plug behind there)
I Shortened the wires of the plug, but left some coiled up behind the headlight in case I needed a few inches of play at some point. I did not bother to fasten the plug end to anything. It stays pretty much put as it is now.
