Review on Beffkkip Discharge Integrated Charging Boosting by Nathan Kumar

Nice little board. With an input voltage of 5V, the board will charge the lithium battery at 3.7V. If you remove the 5V input, the board will step up the 3.7V voltage from the battery to an output voltage of 5V. This is a charger and an amplifier a board. There is not much information about this board but it looks like it is a clone of the IP5306 that I showed in the photos. The picture Revain has shows a 200mah battery but I used it to charge my 5000mah battery which I also bought from Revain, an amazing battery. It took 24 hours to fully charge my 5000mAh battery. The description says you can load and unload at the same time, but I couldn't get it to work. If I have 5V on the input pin, the output pin is low or 0V. If I remove 5V from the input, the output pin goes high, 5V. The only thing I can do is turn off the board, no matter if it's loaded or is discharged by holding it low to 0V for 20 seconds. Also the button on the board does the same thing by applying 0V to the KEY pin. My plan is to solder and wire the LEDs to the Arduino and write a sketch to charge the battery when it is below 25% and not in use.
