Da izvučem iz teksta:
"What has happened with the case of OnePlus and the other out of spec USB adapter cables is that they are not setting this resistor properly. A number of companies are opting for 10kΩ values, perhaps mistakenly thinking that they are meeting the maximum capabilities of the specification when in fact they are breaking it. This could mean that a USB Type-C device attempts to draw 3A from an older charger than can only handle 1A or less, a recipe for destroying your charger or port."
