Hi Tenson, I am Andy from Warp9TD.com, the guys that make the ESS SmoothStepper.

I will reply to this post first, since it is shorter and simpler. There have been more than a few people that have used phone chargers successfully. The biggest issues are:
  1. Does it supply a stable voltage? (Easy to verify if you are within 4.5v to 5.5V, but preferably within 4.75V and 5.25V)
  2. Can it source enough current? (Easy to verify if it can source 0.5 A at 5.0V)
  3. Is it old and flaky? (Weird thinks happen like random drop outs...)


Here are the specs and FAQ that will help you and others answer those questions.


I will write another response to your first post now.

Thank you!

Andy
