Can I charge a 19V laptop from multiple USB ports?

My laptop's charger is rated at 19V 2.1A. I was wondering if it would be possible to build an adapter which would allow me to charge it from a power bank, even if just slowly or via multiple USB ports.

I know you can buy adapters which utilise USB power delivery, but most outlets and powerbanks don't have PD yet.
