Buying Guide

Confirm amperage and plug type

Match the cord to your RV's inlet—most models here are 30-amp TT-30/30A rated; using the correct amperage avoids overheating and electrical issues

Choose the right wire gauge

Look for 10/3 gauge for 30-amp service to ensure safe continuous current capacity and reduced voltage drop on 15–25 ft runs

Consider length vs. voltage drop

Longer cords increase voltage drop; 25 ft is common for campsites, while a 15 ft cord can reduce loss when outlets are nearby

Check for weatherproof and flexible jackets

STW or similar outdoor-rated jackets resist moisture and remain flexible in cooler temperatures for safer outdoor use

Look for useful extras

LED indicators, molded strain reliefs, and included adapters improve usability and help detect live power without extra tools
