Excellent purchase, exactly what I needed and more. So many of my items are now USB powered. I hate using up an electrical outlet for each one. This gives you back your electrical port, plus one, and adds in 8 ports for your charging. Each item I plugged in gave a readout on how much power it was taking. It gives each device just what it needs, and protects from overcharging. This is excellent for my many travels, as it tears down to a small footprint and can be easily stored in a pocket on my laptop bag or backpack.
