Along with the other reviewers here, I purchased this to charge/connect a few idevices and a blackberry (powered) and connect an external drive or two (non-powered). The USB connection works as expected. The power does not.I cannot get any device to charge alone much less two or more. I have tried all the usual different outlet, cable, one device at a time, etc. Contacted Targus support, no help.I do not recommend this product.
