What is the maximum number of extension cords you can connect together?

The key idea is electrical safety: chaining extension cords increases resistance and heat, which raises the risk of overheating, damaged cords, and fire. Because of that, the practical and safety guideline is to limit daisy-chaining to two cords at most. More than two adds unnecessary voltage drop and potential faults, so if you need more reach, use a single appropriately rated longer cord or relocate the outlet rather than adding more cords.
