Amazon Echo Dot 3rd Gen Power Adapter Specs

Here we cover the Amazon Echo Dot 3rd Gen power adapter specs for the AC adapter that comes with this speaker.  First, the US version of this adapter 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. This 12-volt supply fits into a standard power strip or wall outlet.  But it blocks no nearby outlets, as shown next.

Yet the Amazon Echo Dot 3rd generation power adapter silently outputs the correct energy to this speaker.  Also, this adapter offers good regulation.  This lets this little speaker play deeper bass, crisp treble, and decent audio volume.





Further, this is not a low-budget AC power adapter. 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 switching adapter makes fixing it relic exercise.  So don’t bother.

Furthermore, the adapter’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 power supply.

Finally, the AC adapters 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 wall adapter, it’s 12 volts. So, even if the connectors from each adapter would fit the other speaker, their voltage specs make them incompatible with that other speaker.

This echo dot 3rd generation power adapter, including its cable and connector, weighs approximately 4 ounces.
