What is Power Delivery (PD) and does the wall adapter need it? A safe range for a wall adapter is between 45-watts and 96-watts - those will definitely be able to charge your laptop (with normal use).

For instance, if you have a larger laptop or your running heavy-duty programs, a 30-watt wall adapter might not be able to charge your laptop as fast as you’re draining it. This, of course, will vary depending on how intensive your power consumption is. Typically, a wall adapter or portable charger has to output at least 29-watts or 31-watts to give a laptop more power than it consumes by just being on. Is there a minimum wattage required to charge a laptop?
