For the life of me I can not find the answer to this question.

What is the max current that I can input to a TP4056?

Thank you all for the energy and effort put in to this site. Greatly appreciated!

It's all dependent on the one resistor that's on the board. Depending on the resister it can be from 10's mA to 1 Amp (which on the normal TP modules with just 1 IC, is the max)

Note: Julian Ilett did a test of the multi-IC versions that "supposedly" can charge up to 4 Amps (these boards were designed to charge 4 cells in parallel). In his findings, due to the variances in the IC's, they will not Start/Stop at the same time. And for this reason, they will over heat as they are kinda shorting each other out. (a diode stopping current/voltage will heat up)
So, in the end it's better to get 4 TP's and connect each one to its own cell, or just charge at 1 Amp to 4 cells each getting ~250 mA.
