I got mine from northern tool. they are not bad on current. I don't leave it on all night.
it runs on a timeer with a reset button so if you get cold by 2 in the moring just hit the reset button for a few more minetes of quick heat.
with a army down mummy bag they will roast you out of that teardrop.
they cyle on a timer and will shut off at a set time like 30 minetes 45 or what ever yada.
so they don't constanly draw current.
not sure on amp draw. but with my 300 watt road pro heater on for like 15 to 20 minetes to warm the ambent air and a good amry down bag and the heat blanket.
I can be as good as 60 percent by moring.
I can a lot of times even milke out some more juice in the morings when its chilly if needed out of both the heater and blanket and get a bit more out of the battery.
i got a cableas battery montor right in the wall by my bed in the teardrop and it easy to montor juice in the night by just hitting the red button and its a push button on and off.
stays on if you hold it down.
then the battery gauge lights up and tells you what you got with all juice off.
its with in arms reach of the bed and so using 12 volt for heat at night is way easy for me.
then I got a well insulated teardrop with 2 inch foam in the walls and celling. i have a double roof in my teardrop.
and then to re- charge in the morings I normal just start the suv's car engine and just re- charge and idle the engine like 10 15 minets.
the suvs altenartor with a charge line from my postive post on my suvs battery to the deep cyle in my teardrops tongue box will get me with 19 to 15 minets idle time like up to 70 percent or bettor.
it beats a soalar panal all day and is all rigged up with a roll of wire and a 15 dollar rv selnoid and a toggle switch under the dash for pennys.
I recharged my cell phone this way at walk the winds to as i charged up my battery.
often when camping in the summer above lander, wyoming I just jerk camp and re- charge my battery as I drive down the road looking for a new fishing hole.
I can also heat my bed ahead of time with the 12 volt heator and not run down my battery by idleing the car or
if I really want to I can heat my bed as I drive down the road with the 12 volt heator on as I drive and pull my teardrop.
with the cars engine running the battery will stay up at 70 perent much like your cars battery while the heator runs with no loss of charge on the teardrops battery.
once you shut the car off the heator draws the battery down on the teardrop just like leaving your lights on in your car.
but then I am good about conserving my 12 volt battery on my teardrop and its easy with mimal 12 volt usage to get plenty of juice out of a battery in one night.
for me in wyoming 12 volt is way to easy to use with only one deep cyle battery.
