　　Advantages: Supports high current (50A total input), extra-soft cable for easy storage, customizable waterproof rating

　　Price: ¥80-150 (varies depending on wire diameter/material)

　　II. Key Technical Parameters

　　Wire Diameter: 10AWG (6 sq mm) recommended for home/RV use, 8AWG (10 sq mm) recommended for industrial use, UL2459 standard applicable (30-6AWG applicable);

　　Certifications: ETL/CSA certified products are preferred for home/RV use, CE/ROHS certification is required for industrial use, and all products must meet UL 60335 safety standards;

　　Protection Level: Recommended protection level for home/RV use. IP44 (splash-proof) rating; industrial applications require IP67 (waterproof) rating, and flame retardancy must meet V0 standard. Temperature range: household/RV products must withstand ambient temperatures of -30℃ to 80℃; industrial products must withstand temperatures of -40℃ to 105℃. Silicone wires offer better weather resistance than PVC wires.

　　III. Safety Usage Instructions

　　Load Limitation: Total power of dual 30A outputs ≤ 50A input (i.e., 12500W@250V). Simultaneous full-load operation is prohibited.

　　Certification Priority: Choose ETL/UL certified products to avoid uncertified products (which may easily cause overload and fire).

　　Maintenance Points: Clean the connectors after outdoor use and regularly check for cable aging (especially STW sheath cracks).

　　Scenario Compatibility:

　　RV/Camping: Choose Survoltez (with indicator light + handle)

　　Industrial Equipment: Choose the 1688 customized model (silicone cable, oil-resistant)

　　IV. Alternative Solutions

　　If the 3-foot length is unavailable, you can choose:

　　Marinco 5030ARV (16.5-inch short version, 10/3 wire gauge, CSA certified)

　　Paired with a 3-foot heavy-duty extension cable (must be 10AWG or higher to avoid voltage drop).
