I’d like to add a USB port to the handlebars. My phone sits up there in the center and I’m wondering what people are using. I’d prefer something small and unobtrusive. I have the battery tender lead and the usb plug in for it. I suppose I could run a standard usb cable along the bike when needed. But it rather just use a 1’ cable to plug it into a usb mounted up front. Thanks for the assist!
