- Supported charging protocol
- Charging cable
- Temperature
- Battery level
- Device software and charging controls

For example, a USB-C charger may provide basic charging to one smartphone while supporting faster charging on another compatible device.

Therefore, check the complete charger specifications rather than choosing a charger based only on the Type-C connector.

## What Is USB Power Delivery?

USB Power Delivery, commonly known as USB-PD, is a charging standard that allows compatible chargers and devices to negotiate suitable power levels.

A USB-PD charger can support different power levels depending on its design and supported specifications.

If your smartphone supports USB-PD, using a compatible USB-PD charger can provide the charging behaviour supported by the device.

Always check the smartphone manufacturer's specifications to determine which charging standards are supported.

## What Is PPS Charging?

PPS stands for Programmable Power Supply.

PPS is a feature associated with USB Power Delivery that allows compatible devices and chargers to adjust voltage and current dynamically within supported ranges.

Some smartphones use PPS as part of their fast-charging system.

If your phone specifically requires PPS for its preferred charging mode, make sure both the charger and cable setup are compatible.

## How Many Watts Should a Type C Charger Have?

There is no single wattage that is ideal for every smartphone.

Different smartphones support different charging power levels.

Common charger ratings may include:

- 10W
- 18W
- 20W
- 25W
- 30W
- 33W
- 45W
