The backup power options for the leaf look a lot like the Prius and the Volt. Turn car 'on', and pull power off the 12V accessory line. This can either be simple....plug a small inverter into the 12V power outlet (fused at 10A or 120W), or clip a bigger inverter onto the battery under the hood, and get up to 1.7 kW of continuous power, with a higher surge rating due to the 12V battery buffering. Say 1.5 kW continuous and 2 kW surge is completely aok. Of course an inverter that size needs good connections and 100A wiring.
Obviously, the Leaf can only deliver ~20 kWh total, but that could run my fridge, an insert blower, wifi, a couple lights and our small electronics for ~4 days. The plug-in hybrids could go longer (or forever if refueled), but you would have to worry about leaving the whole thing in a garage. Alternatively, every four days I can drive over to the Nissan dealership and pick up another 20 kWh in 30 minutes.
