Portable EV charger

chargeonthegoThe idea behind small trailers like the one shown here is simple, it’s a gasoline powered generator to extend the range of an electric car, but only for those rare times you actually NEED a range extender.  It’s not a completely new concept, but so far, these are mostly still ‘in development’ so I wonder if it’ll ever manifest itself as reality.  With battery technologies continuing to improve and Tesla rolling out its free nationwide EV charging network…the market window for devices like these is narrow and if they don’t start selling them soon, they’ll miss their chance.
