Echo Dot 3rd Generation Charger Specs

Covers the Echo Dot 3rd generation charger specs for the AC adapter that comes with the Echo Dot 3 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’s 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 Echo Dot 3 power cable silently outputs that 15 watts of power to this latest, 3rd version of the Echo Dot smart speaker.  Also, this supply provides good regulation, allowing the little speaker to play deeper bass, crisp treble, and decent audio volume.





Further, this is not a low-budget AC power adapter. It appears well built.  Also, it is sealed. It runs with little heating even at higher volumes.  Plus, it gives off little if any RFI and EMI noise. But while not built for repair, the low cost of this switching supply makes fixing these a relic exercise.

Furthermore, the charger’s DC output connector, the metal barrel part, is roughly 10 mm long.  It has an outer diameter of about 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 chargers for the 2nd gen Echo (21 watts) and echo dot 3rd gen charger (15 watts) look similar.  But you can’t swap them.  This is due to center hole size difference.  Also, there’s the DC output voltage on the 21 watt version being 15 volts.  But on THIS charger, it’s 12 volts. So, you cannot use this adapter useless with the Echo 2.

This charger, including its cable and connector, weighs around 4 ounces.
