Can the TTGO be powered by a li-ion battery?
-
Hello,
I know nothing about electronics.
I'm using the TTGO T-Display ESP32 4MB CH9102F Chip V1.1 to drive a Senseair S8 LP CO2 sensor.
From what I read, the TTGO pulls ~80mA while the Senseair uses 80mA average and 300mA at peak.
Since the TTGO has a plug, I was wondering if the combo could be powered by a single li-ion battery without any extra hardware, as an alternative to hanging a USB power bank.
Thank you.

@winfried Hi. You can use the 3.7V battery in your picture to power the T-display, note the +, — signs.
