JNC AIR 1700 Amp 12-Volt Jump Starter - used

Obtained this around August 2014 and has original battery.  Selling as  is.  I checked the back air pump function and it works.   It looks like the device is still able to have some charge, but since the battery is old, not sure of the condition of it.  But I am able to charge it into the green section as shown.
Does not come with cables, instructions, or original box.  However I will include the extension plug so that you can just use an ordinary power strip or extension cord (pictured extension cord not included) to charge this device.
