The metal bar inside the charger hole in the box is bent upwards. This is a common issue. Unplug the mini power jack (the thing with the cord)Look inside the charger hole on the jambox and take a knife to bend the tab back towards the middle or even lower. Be careful when you replug the power into the socket. The socket tab and the mini plug MUST MEET . There are male and female parts that connect. Somehow on almost all jamboxes the little tab (male part) gets bent upwards, making the connection beteen the charging cord and the charging hole impossible. Just straigthen the tab inside the jambox's mico power slot and you'll be back and running. It may take a few tries and more bending but eventually you'll get the right connection.
