AC Power Adapter Specs for Microsoft Invoke Cortana Smart Speaker




The US version of the power adapter for the Harman / Kardon Microsoft Invoke smart speaker discussed here, features retracting AC prongs, a four-foot long cord, and is pretty light weight for its larger size.  It’s very long, yet its modest width allows  easy fitting into a standard power strip outlet without blocking adjacent receptacles.

Nonetheless, it silently delivers approximately 40 watts of energy to the speaker, and offers good regulation, allowing the speaker to deliver deep, driving bass and impressive audio dynamic range.  This is not a cheapo power adapter.  It appears well constructed, operates with very little heating even at higher output volume levels, and emits little if any detectable RFI and EMI interference.
