Extension cords make it easy to bring reliable power exactly where you need it—on the jobsite, in the garage, around the yard, or for events and holiday lighting. This collection includes indoor and outdoor extension cords, light-duty to contractor-grade, in lengths from short appliance leads to 100-foot runs. Choose the right cord and you’ll protect your tools, improve performance, and work more efficiently.

A quick guide to choosing:
- Gauge and amps: Thicker wire carries more current with less voltage drop. As a rule of thumb, 16 AWG suits light loads up to 10A for 25–50 ft; 14 AWG handles most 15A tools up to 50–100 ft; 12 AWG is best for 15–20A circuits, long runs, and high-draw tools like saws and compressors.
- Indoor vs. outdoor: Outdoor extension cords are marked SJTW/STW, with jackets that resist water, abrasion, and UV. Cold-weather cords stay flexible in low temperatures.
- Safety features: Look for grounded 3-prong plugs, GFCI protection in damp areas, lighted ends that confirm power, and locking connectors that prevent accidental unplugging. Flat plugs and right-angle designs help behind furniture and appliances.
- Durability: Choose oil- and chemical-resistant jackets for shops, tangle-free or braided designs for easier handling, and cord reels for tidy storage.

Specialized options include generator extension cords (L14-30, 30A/50A), RV and marine power leads, and splitters or multi-outlet cords to power multiple tools from one source. For temporary lighting, select cords with built-in tap blocks or cage light strings.

Usage tips:
- Match the cord’s amp rating to your tool and circuit.
- Uncoil fully for high loads to reduce heat buildup.
- Avoid daisy-chaining; use a single appropriately rated cord.
- Inspect regularly for nicks, crushed plugs, or loose blades.
