## Key points

- Check for an official IP67 or IP68 rating.
- USB-C alone does not guarantee water resistance.
- Dry wet cables for 24 to 48 hours before reuse.

## Summary

An IP rating is the clearest way to tell whether a USB-C cable is designed to withstand water. The distinction matters because the USB-C standard itself does not require water resistance, and moisture inside a connector can damage equipment or create overheating risks.

Look for IP67 or IP68, where the second digit indicates protection from water; seals, gaskets and locking collars help keep water out. These cables are used in demanding settings such as construction, maritime work and electric vehicle charging, and prices range from about $10 to ten times that for rugged models. Never plug in a wet cable; unplug it and let it dry for 24 to 48 hours, and replace it if it gets hot after drying.
