The heating elements are PCT ceramic elements, so there's no windings. It's a sensible use of a solid state piece of technology. These sorts PCT heaters are also available in 12V, so eliminating the losses of boosting the battery voltage up to mains voltage.

Waaahhhhttt? Really ? …. 1200 watts at 12v that’s 100amps! Either way, I’m going to look for some 12v pct heaters then! Thanks for the top tips!

Honestly, I'd prefer this design to a PWM control. They tend to cheap out on mosfets.

Yeah, those cheap mosfets go bang regularly! On or off is good!

This seems to be quite small to produce 1200 watts of heat. I wonder how hot the air blowing out is? Try to put a strip of thin paper in front of it, just wide enough so the thermal switch doesn't trip. Measure the temperature and check if the paper begins to char.

Interesting 🤔... Maybe I'll use a thermocouple and power meter... But, that wouldn't be dubious enough! ... Let's chat some paper!!! Good idea!!!

@@DubiousEngineering What I am trying to determine is that if you block the exiting air how hot it gets before the thermal protection shuts it off. Is this is hot enough to start a fire? This can happen when something falls in front of it. For example a cat could knock over a book or a piece of clothing just in front of the heater. A cat sitting on something will knock everything surrounding it to the floor. Cats can do a lot of mischievous and dangerous things. All this worrying is because of the small size and high power. The heat can be more concentrated because of this.

@gordonwelcher9598 .... Totally understand... This is always a risk with a small portable heater... Its actually a really good experiment... I should do it!!!
