The biggest advantage is that USB Power Delivery has increased standard power levels to up to 100W. This means your device will be able to charge much faster than before. Also, this will work for most devices and will be great for laptop users, Nintendo Switch users.
Another great feature of USB PD is Power delivery is a two-way street: One of the most exciting developments in recent USB technology is two-way charging. This means that, for example, your tablet could be used to power a portable hard drive via the charge port. This functionality unlocks bold new possibilities for consumers and manufacturers alike.
Power delivery doesn’t discriminate between devices. PD is backward compatible with devices designed for other USB standards, like 2.0, 3.0, and type-C. It intelligently delivers an appropriate amount of power based on the architecture of the device to which it is connected. Ensure devices are not overcharged and will only provide the necessary amount of juice needed. While most smart phones won’t be able to take advantage of the added power, many other devices and computers will be able to.
