I want to use this powerbank :"VOLTCRAFT LiPo 30000 mAh" for my project which includes various sensors. My main goal is a stable voltage supply of 5V.
Now my question would be, if there would be any gain in stability of the 5V by using a step down converter, and make use of the ability of the powerbank to output higher voltages?
If so, how does the powerbank "decide" which voltage should be output
Many thanks in advance
