Dede's favorite to have for others, charge all devices together! I have two, one in my backpack, one in my car, or leave one at work, one at home!  Love these! Great to have in the car, at work, bedside and more!  Great for connecting your xbox controller to the xbox when your battery is dead, also useful for Android devices.  Know your cord type before you order.  This is a Micro USB.  See photo.  I have a lot of things that require a micro usb charger and I searched for hours for the longest one with the highest charging speed.  Lay in bed and charge your phone!  All Sales Final!
