Best rom for the Z2 Tablet (SGP511), where fast charging works?

[Da9L]

I need some newer Android (6.0+) rom that has fast charging working. I've tried Ressurection Remix Oreo, and Carbon Rom Oreo, but those rom doesn't seem to be able to take charge fast enough. I have the tablet hanging on my fridge to control Home Assistant, so the display is always on, and running that app, but even with a 2400 Mah charger plugged into it, it slowly drains the battery

Any recommendations ?

Okay something strange is happening and I'm wondering if other people have the same experience.. I'm currently trying out the AICP 14 rom, which also seems to have the above mentioned draining problem. What i've noticed is that the device seems to actually gain charge and rise in battery % if i use the device. But if i leave the tablet alone, while screen is kept on, its draining battery. Same charger and cable plugged in, in both scenarios. Whats up with that?
