I have a lot of 18650s pulled from laptop batteries, and was thinking of making a "small" power bank for my laptop.

It's a 19v Sony Vaio.

How would I go about stepping up the voltage with an adequate current? Connect them in series?
Is there an adapter that'll maintain a steady 19v output?
Am hoping for a minimum of 75% efficiency.

Pic unrelated, obviously

problem you are going to run into is since you pulled the 18650s from multiple packs they will be different capacities, resistances, and levels of wear which is pretty bad to make a battery pack from.

I could use them from the same pack?

That'll give me up to roughly 36w of battery power iirc

Get a BMS, and your moste likely fine for what you are going to do with them.

Ive also got close to 100 18650s with no idea what to do with them. I started building a car start module with 4s 9p but got bored.
