I have Chuwi Hi10 Plus 64GB Intel Cherry Trail X5 Z8350 Quad Core 10.8’
I tried to charge the device from Powerbank, but I made a mistake and instead of connecting it to the phone port I connected it to the laptop port (19V) and then the device never worked and I try to fix it now and I want to know what to do.

I don’t think that this kind of device have any protection for overvoltage because generally the protection system is integrated into the power supply, but in your case, you directly connected your tablet to the wrong connector so you damaged the motherboard, I didn’t find much information about your model and to begin with, you have to take a photo of your motherboard and focus on the area around the charging connector, you can watch this video to help in the disassemble process.
