5 Ways to Spot a Counterfeit Extension Cord

Check the UL mark Real UL marks have precise spacing, a registered trademark symbol, and the word “Listed.” Counterfeits often look generic—wrong font, color, or missing details.

Inspect the plug prongs Legitimate plugs have smooth, uniform prongs with no burrs. Counterfeit ones may have rough edges, loose blades, or a thinner ground prong that wiggles in an outlet.

Examine the cord jacket Real cords print the wire gauge (e.g., 14 AWG) every foot. Counterfeits skip this or print it faintly. The jacket should be thick and rubbery, not stiff and plasticky.

Do a smell test New cords should not smell like burning chemicals. If it stinks when uncoiled, that’s a bad sign.

Avoid bargain-bin pricing A counterfeit cord costs a few bucks less and might cost you your garage. Don’t risk it.
