Quick answer
USB-C charger wattage should match the device and cable. Higher wattage is not useful if the device or cable cannot use it.
What to check
- Check the device recommended charger wattage.
- Review USB Power Delivery support.
- Check cable wattage rating.
- Compare single-port and multi-port output.
- Consider plug size for travel or tight sockets.
Trade-offs
A higher-wattage charger can cover more devices, but may cost more and be larger. Multi-port sharing can reduce output per device.
