Plug-to-plug adapters vs single extension cords: Safety first, single cord wins every time

Plug-to-plug adapters (male-to-male or female-to-female) are dangerous and often illegal — they create exposed live prongs and fire risk. A proper male-female connection between two cords is fine, but the safest bet is a single cord rated for the distance and amperage. Voltage drop depends on total wire resistance, not the connection type, so skip the adapter and buy the right length.
