Just thinking. I use a fitbit, and I got into the habit of charging it every few days when I had a shower. (charging it every few days, not having a shower every few days!
)
Is there something i can use inside the bathroom to give me a standard 5v USB socket?
Of course you can get a single socket with a usb in it, but cant use that in the bathroom.
Could I take a supply from the shaver socket, but would it have to come from the output side of the transformer?
Could I use a regular plug in usb charger with European pins and plug it into the shaver socket?
Any thoughts?
