Using esp32 with powerbank (about ampere)

Postby basinus » Tue Jul 04, 2017 6:02 pm

I've got a powerbank with two outputs: 5V / 1A and 5V / 2A. What is the best to use my esp32 (and a solid sd card adapter) with this? Can my ESP get broken when using "too much" ampere? Or can i just use both outputs at the same time, just directly connected to the esp32?

Normally, electronic devices which run on a certain voltage will take exactly the current they need from their voltage source. The amount of current printed on your power bank is just the maximum current the power bank can give. Given that an ESP32 development board usually uses a maximum of 500mA or so, both outputs should be safe to use. (Assuming you actually use an ESP32 development board with an USB connector; if you want to use a loose chip or module you'll need a bit more before connecting it to USB.)
