AC Power Adapter Specs for the Amazon Echo Generation 2 Alexa Smart Speaker




The US version of the power adapter for the Amazon Alexa Generation 2 Echo smart speaker discussed here, features non retracting AC prongs, a six-foot long permanently attached cord, and is surprisingly light weight for its 21 watt power delivery capacity. It’s typical square yet unimposing width and height allows easy fitting into a standard power strip or wall outlet without blocking adjacent receptacles, as shown next.

Nonetheless, it silently delivers that 21 watts of energy to this updated and smaller, yet better sounding version of the Echo smart speaker, and offers decent regulation, allowing the speaker to deliver the deeper bass, crisp treble, and impressive audio dynamic range that it’s known for. This is by no stretch a low-budget AC power adapter. It appears well constructed though it is permanently sealed, operates with very little heating even at higher output volume levels, and emits little if any detectable RFI and EMI interference. While not designed for repair, the low cost of switching supply wall adapters such as this, really makes repairing these sorts of ITE devices a thing of the past.
