I want to charge laptop with 5V2A phone charger. Laptop takes 16V.

There are cheap constant current DC DC boost converter on ali that I could use.

What really happens with laptop when much lower than required current is supplied? Phones doesn't care about it but I've never done that with laptop before.

Will it still charge battery (don't care how slowly) while laptop is turned off? What happens when it's turned on and requires more current than 5V2A can supply, will it pull difference from battery or just go berserk?
