Charging Time - so slow

I am using the power adapter and cable that ships with Nexus 7 but charge times are completely ridiculous . I am getting about 6% an hour. 16+ hours to get a full charge. I've tried killing all apps as well as charging in a power off and suspended state. Any ideas, how to I determine what is at fault.

Regards,

Rick

See what happens when you charge from another source. If a .5 A from a pc charges it faster, your wall charger is defective.

My brand new Nexus 7 takes forever to charge as well. With 2 different chargers.
