Can you use a 100W adapter to charge a device that only accepts a maximum of 45W, for example? Or will this cause any damage to the battery? Thank you :)
There are no devices that "only accept a maximum of 45W" The device draws a maximum of 45W. If the charger is capable of more, e.g. 100W, the device will only draw 45W. The situation is different if a device requires at least 60W, for example. Then the charger must supply this, otherwise it will simply not charge.
