Can I use a 12v solar panel to charge a 19v Laptop?

I saw a cheap 12v portable solar panel on amazon and Im wondering if I can charge my laptop with it, the cell puts out 12v but my laptop uses 19v, can it still be used to charge my laptop (just more slowly) or will it not work at all?
12v will not charge a 19v laptop at all.
Also, the solar panel’s power output is likely to be low if it’s a cheap panel, and even less if it’s small. A panel that can keep up with a laptop would be on the order of 2 feet by 3 feet.
