Here we cover the Echo Dot 3 Adapter specs for the AC power adapter. This is the wall plug that comes with the Amazon Echo Dot generation 3 smart 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, 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 supply makes fixing these ITE units a relic exercise.
Amazon Echo Dot 3 Adapter Specs
Echo Dot 3rd Gen power supply. Model: GP92NB. LO P/N PA-1150-9ABN. Input: 110-240 volts, 50-60 Hz., 0.5 Amps Max. Output: 12 volts at 1.25 Amps. UL Listed: 9T54. CAN: ICES-3(B)/NMB-3(B) AC Adapter. Made in China(P). I.T.E. Power Supply E132068. Polarity: Positive center on the DC output “barrel” plug.
Furthermore, the echo dot 3rd generation power supply DC output connector, the metal barrel part, is approximately 10 mm long, with an outer diameter of approximately 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.
