PTCYICU PTC Fan Heater 200W 110V, Ceramic Fast-Heating Element with Plug | Energy Saving Constant Temperature Thermistor Insulation PTC Car Auto Air Heater Tool for Indoor Outdoor Small Room Use, 60mm

Heats up a small area extremely fast. I was using as a tent heater to kick on just in case the tent temp fell to drastic levels making it too cold, or too hard to evacuate colder humid nighttime air. I mounted it to a tin covered piece of wood and secured it into an old crock pots ceramic lining. Placed it on the floor in the corner pointing up underneath a 6" oscillating fan in order to disperse the heat. You could visually watch the temp rise about 30 seconds after it Kicks on. 2.5x4.5x7' tent so for my purposes it worked great. Controlled by 3rd party thermostat controller.

Got to create a large dry box for my 3D filiment. 75 gallon tote.

Installed this in my Elegoo Centauri Carbon to heat the chamber for printing ABS/ASA. The heater has no built in control- it's always on when plugged in, so you have to pair it with a separate thermostat. It's compact, quiet, and heats quickly.

This small PTC heater does warm up quickly and works for tiny enclosed spaces, but the overall value is limited. At only two hundred watts it cannot handle anything larger than a very small compartment, and there are similar products available for less. It performs as described, but the cost does not match the output.

I used this as a chamber heater in my 3D printer. At 200W its just perfect and it can move the chamber temp around 1 degree C a minute. The fact that it is a PTC is nice since it is somewhat inherently safer, which is one of the reasons I choose it. I can think of many other applications for a small heater like this such as keeping a chicken coop warm.

I got the 200w version of this heater for my 3d printer, expecting it to be 42mm deep, as the listing shows. It is >50mm deep, and it didn't fit for my needs at all. It did seem to heat just fine, but that's the main positive thing I have to say about this PTC heater.

Great little heater, bought it for starts almost a year ago and it's still going strong. I love that it's low power but still puts out a decent amount of heat.

My shop where my 3d printer is located is unheated unless I'm working. This with a pid controller has helped maintain a constant chamber temperature and allowed it to continue printing in ~20 degf temperatures. No complaints.
