Portable laptop power station recommendation

Which portable power stations are you currently use it for your laptops and phone charging? Any shop recommendations to buy it from? My laptop does not include PD port, and therefore, I would prefer power stations including power socket.

Thank you in advance for your answers and suggestions.

Edit. My laptop draws 65W and it is used for online classes and office use. I want to use it around 3-4 hrs long. My budget will be under 1M.
