Write a reviewExtension I needed
Charger reaches my second parking spot now. Connector ends seat solidly, no looseness or arc warnings. Held up to a wet driveway with no shorts.
Built like the OEM cord
Wire gauge looks right, not the cheap thin stuff. Stays flexible in 30°F weather, which is a problem with some cheaper extensions.
