I just ordered a 2013 Time Capsule for 802.11ac. I need a longer power cord than what Apple normally sends with their previous Time Capsules. Currently I'm using an extension cord which just hangs behind my desk (the current TC sits on top of my desk hutch). I would like a longer cord to eliminate the dangling extension cord. Does anyone know where I can purchase a 10 ft long power cord for the 2013 TC? Thanks!
