Default Electric jets where are You?

Given that jet propulsion is based on the expansion of exhaust gases
created by burning some sort of combustible fuel, an "electric jet" is
not possible. Perhaps you are thinking of a ducted fan, which is
nothing more than a glorified propeller turning at high speed inside a
duct. I have absolutely nothing quantifiable here, but I'm guessing
that once you build the motors and batteries big enough to make that
work for any significant length of time, you won't have any room for
passengers or baggage.

There is work ongoing to convert a Cessna 172 to electric power.
They're currently shooting for an endurance of two hours carrying two
people.
