In the United States, a "power_supply=yes" is virtually certain to have
a NEMA 5-15 or NEMA 5-20 socket (120-volt, 15-amp or 20-amp).  However,
knowing that is of limited value, since most RVs have either a NEMA
TT-30 (120-volt, 30-amp) or NEMA 14-50 (240 volt split-phase, 50 amp)
plug.  A camp site may have one, both, or neither in addition to the
NEMA 5 socket.
