Powering electronics projects from batteries is always a challenge as there is no easy way to get stable output voltage without adding extra circuitry to them. One such circuit is a step-up converter that can take the voltage from the battery and raise it to usable 5V for a typical microcontroller.
So far, when I wanted to use a battery to power a project, I was using two modules separately, one for charging - TP4056 and another one for stepping up the voltage - MT3608. When I first saw this new module on AliExpress that combines the two, I was really excited so I ordered a bunch of them and I started testing them only to find a major flaw that really prevents me from using them in situations where they need to be left unattended.
Check out the video to see the module in operation, and to also see its flaws.
