Was wondering, what is the best option to power a NodeMCU on a battery.
The NodeMCU draws around 18mA in deep sleep. Problem I'm encountering is that the current draw is so little, a lot of battery packs don't respond to it when it needs to wake up.
I have tried several power banks, but only the Anker Astro E7 is able to supply power consistently (Plan on getting a smaller battery next since the Astro E7 is 25000mah).
Would using the sunjack setup work? Any fire hazards that might be of concern?
I'm planning on getting this solar panel to test: https://www.amazon.ca/ECEEN-10Watts-Charger-Samsung-USB-Char...
