This means a USB-C charger can deliver significantly more power than older USB standards, and it can do so safely and efficiently.The negotiation process works as follows:

1. The power source (charger) advertises its available power profiles (combinations of voltage and current).
2. The device (laptop) requests a specific power profile that it needs to charge or operate.
3. The power source confirms if it can supply that requested profile.
4. Once agreed, the power source delivers the negotiated power.

With USB PD, the following power profiles are commonly supported:

Voltage (V)	Current (A)	Maximum Power (W)
5	3	15
9	3	27
15	3	45
20	3	60
20	5	100
20	5	240 (with EPR – Extended Power Range)
