About the Attached Cables

The JBL Extreme 2 charger comes in two pieces.  First, we have the DC cable that’s permanently attached to the charger box.  Then there is the AC “cheater” style cord that plugs into the this box.

Next, we show the AC input plug on that box.  This is a pretty standard, non polarized AC cord.  So that means that you can insert the cord here either way.  Furthermore, the standard 110 volt AC plug on the other end of the cable is non polarized.

Additionally, the end of the AC cord that plugs into the power supply is about five eights of an inch long and a quarter inch wide, as shown next.
