This is a rather imperfect comparison, but to try to answer whether the tech is mature enough yet, the Sikorsky 61N in its Pan Am configuration could ferry 25 passengers plus some luggage (though capable of 39 passengers), with a max range of up to 450NM, requiring about 2 megawatts give or take, fuel weighing up to 4000 lbs.
The Sikorsky Firefly is a one-passenger electric helicopter, one of not that many electric helicopters, with a max takeoff weight of about 2K lbs, a little more than one pilot's worth of weight between MTW and its empty weight (no passengers). Over half its weight, 1150 out of 2050 lbs, is comprised of its two batteries, burning up to 140kW for 15 minutes max (IE, not flying like Airwolf).
So the technology is there to make the electric flight about one way before a long recharge with one very wealthy passenger and no cargo provided the passenger is the pilot, presuming the batteries are replaced regularly and it's not too cold.
Maybe they should use solar paneling for the rotor blades? ;)
