Choosing the right extension cords for outdoor projects can make your setup safer, more efficient, and a lot less frustrating. Not all cords are created equal and using the wrong one can fry your gear or slow down your work. Here’s how to choose the right extension cords and power setups for your next outdoor DIY project—plus a few bonus tools we never start a build without.
⚡ Extension Cord Basics: What DIYers Get Wrong
If you’re still using a skinny orange cord from the garage, here’s what you need to know:
- Length matters — Longer cords = more voltage drop
- Gauge matters more — Lower numbers = thicker wire = better performance
- Indoor cords ≠ outdoor cords — You need weather-rated, grounded cables
For most power tools, go with 12/3 or 14/3 gauge cords rated for outdoor use.
