High-performance Fdit PTC Car Fan Air 🔥 Heater (12V 100W) - Ideal for Compact Room Spaces Review

I don't know why. Mine is connected to 12V and should be 100W but only draws 4A at 12V which is closer to 50W. I may have a 24V device, but I am assuming they are the same elements but wired in series rather than parallel as mine. A very good device, but I have calculated that the heat dissipation compared to the losses is about 100W, therefore it cannot reach the desired temperature but approach it over time. but that means it works non-stop just to keep up. prefers a little freedom of action.

This 100 watt heater draws 4 amps at 12 volts. That's 48 watts. I use it to heat the inside of a DLP printer stored in a 50 degree room to 75 degrees. He can do it. hardly. If you're really good, please tell me. I gave it a second star because it gets really hot. I also have a 150W version. This runs at 10 amps - 120 watts. This one is close enough to spec that I can give it the green light. UPDATE: The fan on this model broke after 8 hours of use. I do not recommend.

I've only bench tested this heater but haven't installed it yet. At the same time it seems to heat and blow well and works as it should. It's small so don't expect much. I'm a trucker and sometimes need to sleep on the road in my double cab Chevy, so I think this will work to keep me warm in the truck at night. I didn't expect it to heat up the room or anything like that. Seems definitely good for a vehicle though. I'm running it on an isolated battery FYI. I read a lot of conflicting reviews…

If the heating element and fan run on 12V I wouldn't call it a heater. The fan is blowing too much air for the element to get hot enough. However, if you're running a 5V fan or similar, the element can heat up a lot more, and it generates heat well. Being a PTC heating element, once it reaches a certain temperature it will stop producing heat as the resistance through the element increases as it heats up. You need to know what you are doing as it is not really a plug and play heater. Just make…

They are great for making small heated incubators on the microscope stage for live cell imaging. Make a plexiglass box with one of these (you'll need to cut out the curved plastic fan face first), add a microcontroller (I like the PIC18F2455) and a TMP275 temperature sensor for feedback, and you have a simple incubator at the top of the stage. The fan and heater draw about 4A, so you need a relay for the uController to turn them on and off.

Works for what I needed it for. It's not much heat but I needed something to keep my water pump in my RV from freezing, 12 volts and 10 amps max (my pump is mounted outside the RV in a bay). Fold about 3'x2'x2' and does the trick. I even installed a thermostat. The cost is about $60.00 when all is complete and a little work is done, but I'm happy with it. In the morning it was 14 degrees outside and in 100 minutes it got warmer to 34 degrees. If it stayed on it would stay slightly above zero…

So I ordered a 150w 60mm version of this model from another seller and expected it to peak at maybe 75w , as reports have come in that this version peaks at 50 watts. It ended up using 194 watts before I turned it off - about 10 seconds of work. Nothing good. This arrived later that day (today) and I ran the same test. Left it running for 20 minutes and never saw power draw over 68W including loss when going from 120VAC to 12VDC through the power supply. Sufficient for me, even if not 100…
