How to tell if a USB-C cable is really waterproof

Engadget explains that the IP rating is the key check, and that standard USB-C cables carry no guarantee of water resistance.

The facts

  • According to Engadget, waterproof USB-C cables should carry an IP67 or IP68 rating under the IEC 60529 standard.
  • The USB-C standard does not specify water resistance, so an ordinary cable may survive a splash but nothing is guaranteed.
  • Engadget says to dry a wet cable by unplugging it, shaking out the water and waiting 24 to 48 hours. Skip the hair dryer and the rice, and never plug in a wet cable.
  • Basic waterproof cables cost around ten dollars, while ultra-rugged ones can cost ten times that, according to Engadget.

Case notes · Danny's take

Why it matters

A cable that says "waterproof" on the listing is a claim, not proof. The IP rating is the evidence. Most people never check it, and in a humid city or on a rainy commute that gap can cost you a device. Same rule as anywhere else: verify before you trust.

For builders

If you make or sell hardware accessories, a clear IP67 or IP68 rating is what separates a real product from a vague "water resistant" label. Buyers who are burnt once will check the rating next time.

Not financial advice. Do your own investigation.
