Had Leaf charged with mobile charger

Ran out of charge in my Nissan Leaf again today. Called Nissan USA roadside at 4:03pm.  Original estimate for help to arrive was 5:10pm.  

Received txt msg from Nissan USA roadside at 4:57pm stating that the new estimate was 5:56pm.

Assistance actually showed up at 5:45pm with a propane generator to mobily charge my car.  Hooked up generator until nearly 6:20pm and car was still showing no range available at all, but the mobile Nissan app was showing 4 miles.  Over 2 hours after I called roadside assistance, I drove my car home and hooked it up to the charger.
