Is Primecom the only Level 2 charger with an extended cord?

I need 30 feet of cord (no garage). Primecom seems to have spotty reviews, but they are the only manufacturer that I've seen that offers extended cords (30, 40, 50 feet). Are there no alternatives?

I'd prefer not to use an extension cord because of exposure to weather and also afraid some of the local criminals trying to steal the cord (and screwing up the car attachment site in the process).
