USA adapter

Hi all

Can anyone recommend a good UK-USA adapter with a least 2 USB ports, I need one that isn't going to drops apart after being used a few times.

Thanks in advance

Maybe something like this Power Strip?

Or this: Power Cube

I like the power strips better (I don't have that one, I have something I bought years ago and cannot even remember the name) as I like it all spread out in a linear fashion.
