POWTECH Heavy Duty 6 FT Outdoor Extension Cord
The POWTECH 6 ft heavy-duty extension cord is designed for major appliances and power tools. This UL-listed, 14-gauge cord handles up to 15 amps and up to 1875 watts at 125 volts, making it suitable for washers, dryers, refrigerators, and other large equipment. The grounded three-prong design ensures a reliable connection, while the heavy-duty vinyl insulation resists wear in demanding environments. An angle plug helps it sit flush against walls in tight spaces, reducing cord strain and improving safety in utility rooms or garages. The compact 6-foot length is ideal for behind appliances or near workbenches, where a shorter run minimizes clutter but still delivers necessary power. This cord prioritizes durability, making it a dependable choice where heavy loads are routine.
Key features include UL listing for safety, sturdy vinyl insulation, 14 gauge conductors, and a high wattage capacity that supports common home appliances and shop equipment. Its practical design addresses common installation constraints in busy basements or utility rooms, where space can be tight and wall clearance limited. The combination of toughness and compact sizing helps prevent accidental unplugging and reduces the risk of overloading nearby circuits when multiple devices are in use.

Buying Guide
- Amperage and wattage: Match cords to the load. Look for cords rated for at least 15A and 125V (1875W) when powering heavy appliances and tools.
- Conductor gauge: For longer runs or high-demand devices, 12 AWG or thicker improves voltage stability and safety.
- Weather resistance: Outdoor use benefits from IP-rated jackets, SJTW/CETL listings, and flame-retardant insulation for durability in sun, rain, and cold.
- Length versus practicality: Longer cords offer reach but add resistance and tripping risk. Choose a length that minimizes stretching and clutter.
- Safety features: Look for lighted ends, grounded plugs, surge protection options, and proper wall- or ground-mount compatibility in workshop setups.
- Plugs and outlets: A three-prong design with secure connectors reduces disconnections and improves safety around heavy equipment.
- Maintenance and storage: Flexible jackets and reinforced plugs withstand repeated coiling and uncoiling, extending service life.
