Echo Dot 3rd Gen Power Cord Specs, Replacement

Here we cover the Echo Dot 3rd Gen power  cord specs for the AC adapter that comes with this speaker.  First, the US version of this cord has non folding AC prongs.  It also has a six-foot long affixed cord. Further, it’s light weight for the 15 watt power output. It has a square yet modest width and height. Plus, this 12-volt supply fits into a standard power strip or wall outlet.  But it blocks no nearby outlets, as shown next.

Yet the Echo Dot 3rd gen power cord silently outputs the correct energy to this speaker.  Also, this device offers good voltage regulation.  So this lets this little speaker play deeper bass, crisp treble, and decent audio volume.





Further, this is not a low-budget power cord either. It seems well built.  Also, it is sealed, runs with little heating even at higher volumes, and gives off little if any RFI and EMI noise. But while not built for repair, the low cost of this cable makes fixing it relic exercise.  So don’t bother.

Furthermore, the cord’s DC output connector, the metal barrel part, is about 10 mm long, with an outer diameter of around 4 mm.

The size of the positive lead hole at the top of the barrel plug is roughly 2 mm.  Note, that this is a bit smaller than the 21 watt and larger versions of this cord.

Finally, the AC adapter end of the cords for the 2nd generation Echo (21 watts) and echo dot 3 power adapter (15 watts) look similar.  But they ARE NOT interchangeable.  This is due to center conductor size difference.  Also, there’s the DC output voltage on the 21 watt version being 15 volts.  But on THIS power cord, it’s 12 volts. So, even if the connectors from each cord would fit the other speaker, their voltage specs make them incompatible with that other speaker.





This echo dot 3rd gen cord, including its cable and connector, weighs about 4 ounces.
