If you need permanent USB power on your bike for something like a Quadlock, rather than trying to fit a socket somewhere when you have limited space you can use these boards - https://www.aliexpress.com/item/1005010561246976.html?

You'll find them on eBay as well. I have one tucked inside my front fairing supplying power for the Quadlock and after three years it's still running fine. Obviously it needs to be somewhere dry and probably not too hot.
