Charging USB devices from a powered USB hub?

Question

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

Answer 1

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.

Yes, charging your devices this way is quite safe.

Just make sure that your Hubs adapter does not exceed any device's power supply input which could fuse it.
