I use this USB block for my charging station:

I bought extra data/charger cords for my phone to use as the USB connectors for the Radii, tablets, and my other USB toys that need USB charging. They seemed to be better quality than other charger cords that came with things, and I found a good deal on multipacks of them.
I am waiting for the Amazon delivery of these:

so that I have something smaller for my office desk. I've never tried these, so I can't give a review yet, but the USB Block has worked well for me this past year.
I just ordered the iClever BoostStrip IC-BS02 Power Strip, so I'm waiting also. I'd like to be able to mount it to the side of a cabinet that's next to my charging table, so I'll have to see if that's going to be possible w/o ruining it.
