Hey,
is it possible to power 4-5 ESP 8266 NodeMCU with a Laptop Power Supply. It has a 5V output with max 5A. Instead of power every ESP with its own 5V mobil USB charger ?
Best regards Kai
5A should be plenty as long as you don’t have a heap of LED’s or something connected to the ESP’s. The ESP’s by themselves (and even with a bunch of sensors) use very little current.
