how to make a power bank to charge your laptop? Answered

I have an idea to make a power bank that can charge my laptop, but I don't know how to make it.
The adapter input is 100v-220v~ 1.83A and the output is 19.7v ~3.87A
Please, I really want to make it real and I think many people have the same idea, so I need your help.
