Detailing the use of this heater as an element of an off grid camper or micro home. Warnings and notifications about the power requirements to keep this going in light of the fact that it was originally engineered to be powered by the alternator from a running vehicle, and it will take over 330-400 12v watts of daytime power production to run this heater's 300 watt element, the fan, and the power loss estimated between the power generation, battery charging and battery discharge that goes along with the power draw associated with them. - Навчання та стиль
*Install was easy **fireplace.homes** good although I personally had some difficulty with the thermostat I had. Issue was mine though, not realizing that electric heaters couldn't use oil thermostats. Tip: If you are using an external thermostat, run the power to the thermostat, not the unit. Once that was squared away it worked great.*
I am coming to this party quite late. I am a retired trucker now living full-time in my Toyota Prius. This is the space heater I use when the onboard heater cannot overcome the extreme cold I sometimes experience. It does what I need it to do. I leave my car on 24/7 and let the magical Prius circuitry do its thing but the heater does not seem to turn the car on more than before. Then again, I try to avoid the extreme cold.
Really good review, including the safety advice, thanks.
I have this heater and was working great for awhile but for some reason now it only blows cold air. I have it hooked up direct to batter w/in line fuse, fan works but no more heat. Any help would be appreciated.
These are really just for supplemental use. May raise the temperature of a small area a few degrees but by no means is this little unit going to be able to satisfy most people's desire for "heat". 300 watts is just not enough. Helpful when you first start a vehicle because you won't get any heat from the vehicle heater until the engine has warmed up. Leave the vehicle heat off until it warms up. During that time you can run this. Let the alternator recharge the battery after starting. As far as running a unit like this off a separate battery you won't be able to run it very long. Example; a 100 amp hour deep cycle AGM battery has 300 watts available for 2 hours until you are 50% discharged. Not recommended to go below that although you can. An ordinary flooded lead acid car battery is recommended to not be discharged below 80% and has a lot less power available for something like this.
A how did u connect the power-hunt power port to the 12v direct-wired heater in the video? I need to know
In regards to his comment about automobile alternators having only 30amps;
No automobile has a 30 amp alternator unless you're taking about antique tractors. My lawn tracror is 15 amps for example... enough to run lights and an air pump sometimes.
A 70s truck will have about 60 amps. 130 to 150 amps is typical car alternator from 1990s on up. Many work trucks and RVs have dual alternators at over 300a or single one at 200-240amp. If buying a new RV spec it with highest amp alternator/s
Long story short any reasonably modern minivan, SUV, or truck will make more than enough power to run 30 amp accessories.
Mostly but at idle with other accessories also running the battery may actually be discharging depending on the total load.
Will this unit draw down a battery on a side by side if you connect directly to the battery and only use it when the side by side is running ? Thank's
About how long is the chord on this?
Would you recommend this for my 2025r compact tractor cab
Just love your "In depth"-review, maan! I now know that the heater is below 50$, maaan. Who cares what wattage it draws and what temperatures you get. The main thing is that you got the price right and what the on/off switch does.
Showing your mate what you bought does not qualify as a review.
Where did you buy it
The 300W rating is based on the heater running on 13V to 13.5V (typical system potential of a running car). Mine runs about 250W on a 12.5V battery bank.
The 'speed control' is just a 10 ohm 3/4 turn potentiometer, which is worthless with a brushless muffin fan (because a 555 and switching FET or a fan that had a PWM speed control input would add *sooo* much to the build cost /sarc).
Having seen the internal construction, I wouldn't pay more than $15 unless you absolutely need one.
I could not find anything with comparable heat output under $30 but you know how it is, if anything is 12v, the price goes up.
+randacnam7321 how do you know all this chit
Nicos A I read the labels and took a course in automotive engineering back when I was in the Marine Corps.

Poking around inside mine as I have one of these heaters.
What are youre recommendations for the best portable heater for trucks ?
I keep buying little portable heaters that you plug into your car lighter and within two weeks end up sending them back to Amazon because they either stopped working or they don't produce heat at all in my truck I keep searching to find a little heater I can't find s*** sure wish I could if you found any please comment back and let me know
Can you install this with a rocker switch so you don't have to unhook it from battery every time you turn off the motor
Yes thats what i did and i'ts best thing to do if you don't want to drain the battery off
Running this heater, you are talking about the car not running, right???
What if the car is running, is that going to cause a problem???
I am only going to use this heater while my car is running back and forth to college, 30 minutes each way...
How many price
I did not care for mine not enough heat for my application in van just to warm up front end of van during winter months use diesel heat now instead...
How do you put your dinner in it?
and furthermore, will this work in my Honda? (¬ ͜ʖ¬)
👍ty
I found that it drew a HUGE amount of current & actually put out very little heat. I then threw the piece of s___ away. BTW, I now use a Totmox heater which draws not much current & actually heats!!!!
unusual to have solar light when using heater. but recovery time. :-).
My 74 Chevy has 45 amp alternator. My new truck has 125amp. 🤷🏻♂️
I'm trying to electrically heat a small 2 seat airplane cockpit. I have a dedicated odyssey pc 680 Battery to power it. I have bought this unit and another smaller one but they don't seem strong enough. I need the power of an AC small ceramic space heater w/o the AC power. Any ideas?? thanks in advance.
No battery is going to keep this going for very long and I would not want to risk taxing the aircraft motor's ability to generate sufficient power to run a heater unless I knew more about how it is set up.
I bought one of these and they are junk
OK then, but compared to what? I have tried a few 12v heaters and not found any that I consider "really good" but this seems decent. I don't get paid anything from RoadPro, so I am not married to them in falsely promoting their products, but I am not finding good options out there on 12v space heaters.
+8digitPDX Build your own, I made a 50watt 12v **handle warmed wrench, with cheap wire and electrical tape.
Cost me less than a dollar. Helps when holding a cold wrench in -25f.
@@DarkLinkAD How the hell does that heat a small trailer or vehicle cab???
@Art Vandelay Okay simp, ill spoon feed it to you.
Drag your ass down to the dollar tree..
Go to the automotive section, youll see a pack of wire, it comes wound in 3 sections.
Use one of those windings and wrap around your insulated wrench or hammer until you read 5 amps, or you have enough that doesnt burn your hands any more..
5 amps, 12v is a 60w warmer..
Understand these principles and you can create a resistive heating element that would otherwise cost a pretty penny..
@@geographyinaction7814 How? With effort and a hell lot better than chinesium imports.
Average car battery is 500-600 amp, so this heater draws about 25 amp/hr at 12V , theoretically should run for 8-10 hours. In cold weather battery output can drop as much as 50%.
+szaki That's the cold cranking amp rating, not the amp/hour rating. This heater would drain a single car battery in under an hour.
BS! Battery has about 50-60 amps, this heater don't use more than 1-2 amps/hr.
It takes my battery to charge, from empty at 6 amp, 8-10 hrs.
+szaki lol 1-2 amps an hour?? thats 24 watt's max. these heaters use around 25 amps.
another thing to consider is that if you have a 60ah battery you will not get 60ah of it.. more like 40 amp hours.
you will be looking at about an hour run time in the real world.
I think, you right! Never could figure out, these Co.'s do all kinds of weird advertisement, how good their battery is!
i know its terrible.. its like advertising a car with a 4 litre engine that actually only has a 2.9 litre engine.. i don't know why they bother overrating them all
I bought one. it is a total piece of shit
its only going to stay hot when u shut it for a few seconds haha total shit
No thermometer or air flow test. Useless!
