Heads up about Echo power supply going bad! After 1 1/2 years of enjoying the Amazon Echo, it would no longer connect to the internet; the blue ring would never turn red and then the Echo would shudder and restart the process. I assumed the motherboard went bad but I couldn't find any repair or replacement options. I then bought a new Echo and plugged it into the old power supply. Guess what? The new Echo did the same thing as the old Echo. I then tested the new and old Echo with the new power supply and they both worked! The power supply specs are 15 volts, 1.4 amps.
