If you're looking for something on the more practical side, we recommend this 20-foot extension cable from Quick Charge Power. With J1772 connectors at each end and capable of handling 40 amps, this cable is safe and compatible with every plug-in vehicle that isn't a Tesla.

Besides home use, it can really come in handy if you need to use a charging station but a gas-powered car has been parked in front of it. It's available on Amazon for $198.56.
