$3450 and only works on '13 and on Leafs(not '11 and '12 as you said) and the Mitsubishi Outlander PHEV of all vehicles, no other vehicles including other ones using the Chademo standard.
The Setec Power device is a 3000 watt inverter that can communicate to an EV battery via the CHAdeMO V2H protocol. The Vehicle to Home (V2H) protocol with the CHAdeMO standard allows discharging from an EV battery, turning the vehicle into a mobile generator. This Vehicle to Load (V2L) device enables mobile backup power anywhere. This is a perfect solution for power in a blackout, especially for renters that cannot install a full V2H system.
It is compatible with any Nissan LEAF (model year 2013 or newer) or Mitsubishi Outlander PHEV with the CHAdeMO inlet.
The system weighs 33lbs and can easily be carried using the handle"
Interesting looking device but probably not in my future.
