Amazon Echo Dot 3rd Gen Power Adapter Specs

oneHere we cover the Amazon Echo Dot 3rd Gen power adapter specs for the  that comes with this speaker.  First, the US version of this supply 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 runs with little heating, even at higher volumes. And it 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. Plus it has 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 adapters for the 2nd gen (21 watts) and 3rd gen Echo Dot power adapter (15 watts) look alike.  But they ARE NOT interchangeable.  This is due first of all, 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 were the same size, the voltage specs make these adapters not cross compatible.
