Questions

Hello, I have an inquiry, can I replace the TP4056, and both the micro-USB breakout and female usb port with this? (refer to image) I got it from an old power bank that was lying around the house. I was wondering if I could skip it and be okay with going through hooking it up with the boost converter.

Pretty cool setup and worked pretty well until a point.
Either the TP4056 or the stepup converter started acting up after the batteries drained completely and on the USB output I was getting 19V (and I was not able to adjust it anywhere below 18V)!

My charger doesnt have the out terminals, it only has the input and bat terminals. What to do?

look for TP4056 with protection, they have 3 ICs and has two more terminals (out) adjacent to the battery terminals.

Hi, i made this project. But i have little problem , charging port gives only 0.5A , how can i boost it ? If i can .

I have a Problem! One of the 3 pairs is ~1V lower than the other 2 (~3,33, ~4,5 & ~4,6) Can I still use all of them?

Could you use this to power a raspberry pi 2? What amps does it supply?

1,2A... the max output current of the protection board is only1200mA

Hello. I made the connections like this (tested 5V at output), and my cellphone wont turn on after that (it died basically). I suspect there was current overflow. Any ideas if I definitely lost my phone? Is it worth to buy another battery or any other component that might have burned?
