My laptop charges with USB C, so when the standard charger broke, I just used the USB out port from an EcoFlow battery. The display on the battery said the laptop pulled 25-30 watts while charging. So, why can't I use just any USB brick that can output more than 30 watts?

Is there something that is bound to go wrong that I don't know about?

Are laptop chargers really that special?

It depends. Some laptops won’t switch on their full cpu/gpu if they aren’t connected to enough power.

My Lenovo for instance will switch to a high refresh rate when using its native power supply.
