Power Cord Specs for Invoke Harman Kardon Speaker

Details the power cord specs for the Invoke Microsoft Harman Kardon Cortana speaker.  First, the US version of this AC adapter has folding AC prongs, a four-foot long cord, and is pretty light weight for its larger size.  Next, the AC adapter box end is quite long.  Yet its small width allows  easy fitting into a standard power strip outlet without blocking nearby sockets.

Furthermore, the cord silently puts out 40 watts to the speaker.  Plus, it offers good regulation, allowing the speaker to sound off with deep, driving bass and life like dynamic range. 

This is not a cheapo power cord though.  It seems well built, runs with little heating even at higher speaker volumes, and transmits little if any RFI and EMI static.
