Is it a good idea to get a high wattage phone charging brick and standard USB C cord to use for a laptop charger? (lemmy.world)

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?

I'm not sure about specifics, but generally, charging a battery with more power will charge faster, but puts more wear on the battery, decreasing it's longevity.
