Charging USB devices from a powered USB hub?

Hi, I have just bought a "Targus Desktop USB 2.0 4-Port Hub w/Audio Pass-Through" ( http://www.targus.com/us/productdetail.aspx?sku=ach80us ) powered USB hub. I also have a number of portable devices I usually charge from my PC or notebook via USB cable: Sony NWZ-S545 mp3 player, Amazon Kindle 3 ebook reader, an old Mio C220 satnav, a Nikon still camera etc. My question is wheter or not I can SAFELY charge these devices from the USB hub itself. I mean, I power up the HUB but do not turn on my computer, just attach these devices to the hub. Will they charge? Won't they overcharge? Should I connect them to the normal USB sockets of the hub or the "hi power" ports? Thanks

They should charge normally from the powered hub, the computer doesn't need to be on. The whole point of powered hubs is to eliminate crashes and lockups when USB devices draw more power than your computer's system bus can provide.

   Now that is marvellous.
   The Kindle completely baffles me. I regard it as one of those almost immediately obsolete and slightly pathetic devices that is inevitable in the early days of new gadget development, ultimately to be forgotten except in 'look back at 2007' shows when it will be mocked for having all the design sensibility of an Etch-a-Sketch. And I'm still not buying the fact that a portable ebook reader is at all necessary.
