anyone recommend a good one, mains powered, need one to charge up all my USB stuff in one go.

To be honest they're all much of a muchness. I don't have a powered one myself but I did buy a couple of double plug sockets with USB charging ports from Screwfix. Best invention ever.

To be honest everyone raves about the double plugs with USB's. Best place for them is the ones low to the floor or in the kitchen just above the counter

I've been meaning to buy those usb Twin sockets for an age but just getting round to buying and fitting them
