Compact PTC Fan Heater: 12V 50W Portable Ceramic Air Heater for Quick, Efficient, and Heating

I used it to heat a 15 square foot enclosed work space. Pretty quiet fan, unit heats up quickly.

Received it after the sun started to set and with snow already on ground, it was a bad thing to have with so little heat produced!

The media could not be loaded. I ordered the 12v 50w version. This little heater is very compact and was nicely packaged. The fan and heater are individually wired. This will allow you to control both components separately. You can add temperature controls, speed controls, on/off switches, etc. There are so many options for this. I build portable power stations with 12v batteries and charge them from solar panels. I've been looking for a small heater that I could add to the power station I keep in my car. I've tried a few different heaters, but they either didn't get hot or they consumed too much energy. When you are running off of battery power, you need to conserve as much power as you can. I will be using this little heater to help heat up my small tent and car. This is not going to really heat up the area, but I can warm up my hands or feet and keep it on the side of me while laying down. It will also help keep my battery warm in extremely cold temperatures. I first tested this out with one of the power supplies I built. I thought the fan was backward because it felt like the air was blowing out of the back. After taking it apart, I realized the fan was actually on correctly. There is just a lot of air flow restriction from the heater. Besides that, this is better than I thought. It heats up quickly and gets very hot. I am going to mount the heater as is for now. I am planning on upgrading the fan with one more powerful. I have a bunch of fans from old devices lying around. If you are looking for a compact heater that consumes very little energy, this is great. It works better than some of the 12v defrosters and uses a quarter of the power. I didn't test the power consumption or temperature yet. This is a 50w unit but it can be + or - 25%. This means it may be plus or negative 12.5 watts. It will fluctuate up to 62.5 watts when heating and may fall down to 47.5w while maintaining. I saw another reviewer state their unit was pulling 85w. I didn't want to pull out my multi meter and temperature gun to measure everything. For now I just hooked it up to a 12v 5a fuse. If the heater had gone over 60w it would have blown the fuse. It didn't blow so it's safe to assume the one I received stays within spec. Once I install this unit I will test it with the proper equipment and update this review with my findings.

I can’t speak to long term reliability since I just got it but I’ve been testing it and it all works well.The listed lower requirement isn’t quite accurate though. Nominally this heater may be 50 watts but on the side of the heater has a thing saying plus or minus 25%. I hooked it up to my power supply and current meter and it was pulling 85 watts at peak. Not a big deal but that means you’ll need a 12v power supply of at least 7 amps to properly run this.I also checked the temperature with a temp gun and with the fan running the hottest part of the radiator registered at 155 degrees F. I didn’t test it without the fan.I’ve read reviews of this style heater on a few listings and it seems like the most common point of failure on these is the fan. This is actually convenient because the fan is a standard 60mmx15mm (maybe 10mm) PC fan size. I’ll likely preemptively swap it with a 3 pin noctua for $15.I got this to use as a heater for my Saturn 3D resin printer. It’s exactly the type of heater Elegoo and the other companies use for their heaters, only theirs are more nicely designed overall. I already had spare arduinos, relays, and a power supply so I opted to get just this heater module to make a stripped down custom version of what the OEMs are already offering. Works great so far.

Heater works great, the fan came broken, didn't spin at all under 12v. Luckily I had a spare around but this would be useless otherwise.

I installed this in my 3d printer to allow me to print abs without waiting so long for my chamber to heat up. It does a great job and easily gets my printer up to 70C. It could go hotter with more insulation but this is enough for my purposes so I am very happy with it.

Review for: Compact PTC Fan Heater: 12V 50W Portable Ceramic Air Heater for Quick, Efficient, and HeatingSurprise, a small heater that actually delivers the power it advertises! I tried a couple of the small 12V, 100-200 watt car heaters and they fail to produce the heat advertised. I will be using this in a smaller electronics box that needs to be outdoors in cold weather (Wisconsin winters). I think it will do the job very well, provided that it lasts...and I currently have no reason to doubt that. Besides, it is packaged much better than the car heaters.I ran some tests on the heater:Fan draws about 100mA at 12.0VHeater draws about 5.1 amps at 12V, 5A x 12V = 60 watts of heat!If you don't need that much, use a lower voltage. The heater draws 1.3 amps at 5VDC for about 6 watts of heat. There are separate fan and heater leads so you can keep the fan running full time if you use a thermostat as I will (I want to keep the fan running for even heat even when heater is off), or want to run the heater at a lower voltage and keep the fat at 12V. Overall, I am impressed with this little heater.Of course, if this heater give me trouble over the winter, I will update this review.

Fan is not strong enough as expected. It heats up quick but in needs to be near the component you want to protect from the cold. You can separate circuits between the heater and the fan (Adding one switch for the fan and another for the heater). Acceptable price.
