Hello, please help. I bought an external battery df trio-03 for 15000 mah for the Samsung Galaxy Tab Pro SM-T525 tablet, it charges from it only when the screen is on, as soon as it goes into sleep or standby mode (I don’t know what to call it, in general, when press the power button and the screen goes blank) charging immediately stops! I charge from the most powerful connector 5V - 2.1A (on my own charger it is written that the output is 5.3V - 2.0A) Other gadgets like the norms are charging. The firmware is native, rooted. Thanks in advance.

One thought puts your tablet on a strong external battery and there is no 5 * 2.1 there, but the fact that on the screen it seems that it is charging does not really mean charging.

Well, you just need to measure the amperage when charging. I think the power bank just does not pull out.
