I have a Gen 1 EVSE Upgrade in great condition. It has a L6-30R on it and has been upgraded by EVSE Upgrade to supply up to 20A/240V or 12A/120V and is adjustable in 1A increments down to 6A. It is in great shape and only lightly used. It includes a 5-15P adapter for 120V charging up to 12A.
EVSE Upgrade currently charges $249 + your existing EVSE for this service, I'm just looking to to swap for a stock Nissan EVSE (any year) + $100. If you wish to buy it outright, let me know your price.
