So, I put the SAE connection from my new battery tender Jr. On my 800gs. It has a 7.5amp in line fuse. My question is: I would like to run a few different things during different situations off that SAE plug. My cell phone (ANDROID with mini usb) and gps (zumo 550). Will that 7.5amp fuse surfice running either one of those? Or is it too much, and cause damage before it blows. I am an electrical retard.
