Good, powerful and inexpensive! (I wrote)

This power supply via USB is very powerful with 1000mAh - and can be used by Y cables and electrical supply power hungry 2.5 "HDD.
Thus one blocked no second USB socket, but fed separately to the additional current.
Even a "Kindle", you can load it, or a PCMCIA card in addition versogen with electricity. Background - makes you so via USB of your computer / notebook, you always blocked a USB socket.
I particularly like the warning light, thus you will not forget to pull the plug after use.

Edit 23/10/2012 - with a loud crack goodbye just the NT - was around the time perhaps 15 x for charging our Kindles used! And: After charging from the socket when pulled. Well, for the time 4.10 is worth no complaint, but instead of awarded 5 stars, there is only one!
My daughter always invites over the original Kindle Adapter - going yet, incidentally.
