5 Reasons Not to Daisy-Chain Extension Cords

It creates a fire risk Every connection adds electrical resistance, which generates heat. Two cords linked together overheat more easily than a single cord of the same length.

It creates a tripping hazard The connection point where two cords meet is weak and easy to pull apart. Exposed live prongs become a shock risk.

Voltage drops over longer runs Daisy-chaining increases the total cord length, which reduces voltage to whatever you plug in. Tools and appliances may run poorly or overheat.

Taping the connection doesn’t fix the problem Tape can hide a loose or partially pulled-apart connection. The underlying risks of resistance and overheating remain.

A single longer cord is safer and cheaper in the long run A proper-length extension cord costs $20–30 and lasts for years. It eliminates all the risks of daisy-chaining with no downsides.
