This 14 AWG, 3-wire grounded cord is rated for 15A, 125V, and 1875W, designed to handle higher power while reducing heat risk compared with thinner cords. The low-profile flat plug sits flush against the wall, making it ideal behind couches, TVs, or bookcases where space is at a premium.
Best for: Living rooms or entertainment centers where furniture sits close to outlets and a neat, space-saving solution is needed. It’s also a solid option for daily use with high-power devices.
Caution: Longer runs can introduce more voltage drop; for maximum performance use the shortest effective length.
Go Green Power GG-25606 6ft
The 14/3, 6-foot appliance cord features a grounded right-angle plug to guard against accidental disconnection, ensuring secure connections for large appliances like air conditioners and refrigerators. It is designed for kink-free daily use with a durable outer jacket that blends into home décor.

Caution: Longer cords can incur greater voltage drop; use the shortest length that meets your needs when possible.
Buying Guide: How To Choose A Heavy Duty Appliance Extension Cord
What matters most when selecting a heavy duty appliance extension cord?
- Amperage and wattage: Look for cords rated at 15A and 125V (1875W) for most major appliances to prevent overheating.
- Wire gauge: A 14 AWG cord handles high power with less heat buildup than thinner gauges; for longer runs, consider thicker gauges like 12 AWG if available.
- Plug design: Right-angle or flat plugs can save space against walls and furniture; ensure the plug is grounded for safety.
- Length versus voltage drop: Longer cords may experience voltage drop. Choose the shortest cord that meets your distance needs.
- Indoor vs outdoor: Outdoor-rated cords (SJTW or similar) provide weather resistance; indoor cords may be insufficient in damp or outdoor environments.
- Durability features: Look for durable vinyl insulation, flexibility in cold weather, and protective jackets to reduce cracking and wear.
