RVGUARD 50 Amp RV/EV Extension Cord vs ZAZFO 50ft 50A RV Extension Cord

Both are 50 ft, 50 amp NEMA 14-50 extension cords, so the choice comes down to jacket and gauge. The RVGUARD uses a heavier 6/3+8/1 STW jacket and carries cETL certification, which suits full 50 amp RV service and Level 2 EV charging. The ZAZFO uses an SJTW PVC jacket rated IP65 and flexible to -40°F, which is easier to coil and store. Owners rate the RVGUARD higher on a smaller sample; the ZAZFO has more ratings at a lower average.

• Choose the RVGUARD if you want the heavier 6/3+8/1 STW jacket and cETL certification for a 50 amp RV pedestal or Level 2 EV charging.
• Choose the ZAZFO if you want a more flexible IP65 jacket that coils easily and handles cold weather down to -40°F.
