I replaced the diode with a 470uF polarized capacitor (biggest I could find). No effect on the current (or anything else) whatsoever.
Is it possible that the boost converter is simply broken?

Re: I'm getting constant brownouts powering ESP32-CAM
Hah, if it were so simple... 
The brownouts occur regardless of whether I crank up the converter to 6V or remove the diode completely. There isn't even a change in the current with or without the diode - always oscillates between 120-150mA.

1N4007. There was no reasoning behind choosing this one. I just had those diodes lying around.

7.4v battery charger
Does anyone know if there is a module like tp4056 but with a 7.4v output? Something that can charge double battery packs?

I'm getting constant brownouts powering ESP32-CAM
Hi, I want to create a solar charged camera, but got stuck half-way. I'm getting a brownout the minute I power WiFi on the ESP32-Cam with the setup from the picture. The voltages are all ok - 4.1V on the battery, ~3.8V coming out of TP4056, solid 5V out of the boost converter. The current however is...
