Wechselwandler for laptop in the car?

Hi

My laptop power supply shows 65W 20V.

When Wechselwandlernn on Amazon, there are different watts of strength for the converter (75-400W)

If I buy a converter with more watts, does that mean that I can connect more devices… / more power?

Does the laptop pull more on a 150W converter than on a 75W?

How long will the car battery last at 1x laptop load per day?

Sometimes casually explains:

The laptop always "pulls" the same power, a "higher power" converter can give more, but the laptop only gets what it needs.

Similar to a water barrel, where you open a tap, with a "big barrel" does not automatically flow more in quantity through the tap, it can only flow longer water.

It could only be a problem if the converter delivers less power than the net needs. Either you overload the converter, or the LAptop is not fully charged properly.
