Since my laptop charges with USB C, so when the standard charger broke, I used the USB from an EcoFlow battery, and 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?

    Thanks for that thorough explanation! As someone that knows enough to be suspicious of the usual problematic factors, but not really aware of the details, this was great info
