We are about to have some exceptionally frigid weather here near
Boston.  Unfortunately, I need to go out and will be parking my
car outside for 4 hours or so.  That has me wondering whether one
can use a trickle down charger that plugs into a cigarette lighter
in a (2005) Prius.

My readings do show that they can be jumped, but I hope there is
no need for that.  My battery has not had any problems, but then
it also has not been subjected to such cold temperatures before.

Thanks,

Unless modified, the cigarette lighter is inert when the car is not in
READY. A tickle charger directly connected to the battery is a better
solution . . . be sure to put an inline fuse.

My 2010 started fine at -27F yesterday.  The little battery in back just
powers the electronics and a few lamps.  It's that big traction battery
under your back seat that starts the car.  Coldest start I've had with a
Prius was -36F when I had my 2005.  That car still has the original battery
and my daughter has started it below -20F a couple of times in recent weeks.
I had to jump the 2005 twice, once when I left the dome light on for about
48 hours and once when I left the door ajar for several days.  Despite
running it down, it just keeps going and going and going.......

 I have a 2007 model....  When the 12 Volt battery died last year I
replaced it myself.

While I had the battery exposed, I went ahead and mounted a 'cigarette
lighter' receptacle with 10 Amp fuse in the little plastic panel
located just below the access hole to change the stoplight bulb.  That
way I can plug in a tire pump, small inverter or phone charger
directly to the 12 Volt battery without having to have the car ON.

You could connect your trickle charger via the same receptacle..... Of
course getting back there is a problem if the battery is too dead to
activate the electric trunk lock.

Thanks to you and others here for the responses.  I procrastinated
and went out when the temperature was about 10F and had no problem
after 6 hours.
