We cover the AC power adapter specs for Amazon Alexa Echo Dot 2 smart speaker here. Specifically, this is an often seen medium-current USB switching power supply. Furthermore, the detachable cord has a female A style USB connector with the usual USB wattage. See it in the next picture.
Now the US version of this USB power supply sports a standard 120v two prong, non polarized plug. It has non retractable prongs, as displayed next.
But foldable prongs are not always helpful. That’s true for non portable uses for the speaker, since this speaker needs external power to work. One problem is that foldable prongs can loosen over time. Thus, they can develop faulty connections. Therefore, this might cause poor operation and speaker cutouts. Now it’s true that you are not likely to plug and unplug the Echo Dot 2 power cord much. So we feel that folding prongs would give little added value here. In fact, they could cause lots of problems instead.
