Amazon Basics 50-Foot 3-Prong Indoor/Outdoor Extension Cord

- 50 ft, 16 gauge, 13A
- ETL certified, grounded
- Vinyl jacket, all copper
Our take
The best mix of length and grounding under $20.
Why it made the shortlist
Amazon Basics is a 50 foot grounded cord with a 3-prong plug, rated for 13 amps, 1625 watts and 125 volts. Its 16-gauge all-copper wire sits under a vinyl jacket that resists moisture, abrasion and sunlight, and it is ETL certified.
At about $19 it costs a little more than the GE 40 ft and gives you 10 extra feet.
It suits a campsite pedestal or a picnic table far from the post. Use it with lights, a fan and chargers.
What works
- Longest reach in the guide
- Grounded three-prong plug
- Resists moisture and sunlight
- ETL certification
Watch out for
- 16 gauge limits heavy loads
- Bulky to coil
- The catch
- Fifty feet of thin wire loses voltage under heavy loads.
