Will this work for charging my EV?

Yes, if your charger uses a NEMA 14-50 plug and the outlet is a 14-50R on a 50 amp circuit. It is a straight extension, not an adapter, so both ends must be 14-50.

What gauge wire does it use?

It uses 6+8 AWG STW cable, which is the size expected for a full 50 amp run. That is why it is heavier than 30 amp cords.

Is it safe for outdoor use?

It is built as a waterproof, heavy-duty outdoor cord and is ETL listed. Keep connections off the ground and protected from standing water.

How long a run can I use?

Lengths go up to 100 ft, but longer runs increase voltage drop. For EV charging, shorter is better; check your charger's guidance for maximum cord length.

Does it come with an adapter for other outlets?

No. It is a 14-50P to 14-50R cord only. You need a separate adapter to connect to a different outlet type.

Our take on the Vantecable 50 Amp RV/EV Extension Cord

A 50 amp NEMA 14-50 extension cord that runs from a 14-50P plug to a 14-50R outlet, built for RVs, EV chargers and marina hookups. It uses 6+8 AWG STW cable, is ETL listed, and has a waterproof outdoor jacket with a grip handle for pulling the plug in wet or cold conditions. It comes in lengths from 10 to 100 ft, so you can match the run to your pedestal or garage layout. The main trade-off is weight and stiffness: 6 AWG copper at 50 amps is heavy, and long runs are bulky to coil and carry compared with lighter 30 amp cords.
