    After the recommendation from the Best Buy salesman, we purchased this item. However, it did not charge our Galaxy 2 tablet. We had to return it and someone from the Geek Squad had to come over and instruct the Samsung help on which ones would work and why.

    I haven't noticed if the PowerBlock USB Wall Charger's ChargeSensor technology makes my iPhone charge faster, but it does the job. Make sure you don't need a USB cord if you want to buy this wall charger because it doesn't come with a cord.
