Thanks for the info. Not that I have that problem... I am using one of those cheap DC-DC regulators from the internet LM2596 (I believe) adjusted at 3.3V. Oversized? absolutely... but no power problems.

exactly! as you are developing you dont want to deal with power issues. when you have something that works perfectly with your "over-sized" power supply you can scale back and see what you can get away with without getting into trouble. after a lot of options I landed on an old laptop power supply and a power regulator. perfect low cost solution.

However, if i connect it to a Phone charger, esp8266's AT commands doesn't works fine. What will be best option for fix it? Could you put a simple schematic here? Thanks
