SJTW vs other extension cord ratings: SJTW is the best all-around choice for home use

SJTW covers indoor, outdoor, and heavy use without breaking the bank — the J means 300V (fine for home), T means lightweight and flexible, and W means weather-resistant. Other ratings like SJTOW (oil-resistant) or STW (600V) are overkill for most people, while SJO lacks weather protection. For 99% of home, yard, and garage needs, stick with SJTW.
