2pcs PTC Heating Element 5W-50W AC DC 12V 220 Degree consistant Temperature Ceramic Thermostatic

works great

I picked these up for a little project. The get very hot and heat up quick.

I bought these because I wanted to create a small thermostatic heating chamber. I have done some testing and they seem to cap out closer to 390°. I have yet to test a situation where I create a conduit to direct the heat and a form of insulation to keep the heat from escaping my desired area.Slightly unfortunate that it requires a separate power source that's not included. I was able to find the appropriate things to make it so I could plug it into a USB

These work good. Did not see a UL listing on these. Or a voltage rating marked on the unit or even the packaging.

Works as described

Ok

If you want to limit the maximum temperature, these will not (no adjustment). They will heat to the rated temperature. I was using to heat air coming into an analyzer. However, the devices will produce a slight degradation smoke that is enough in my case to throw off the readings in my application.Probably good for heating anything that will hold up to the maximum temperature. These are essentially raw heating elements, and should be used accordingly.

Solid coild. Pumps out heat as designed. I have it layered between bricks to keep my feet warm with a 12vdc battery charger. Units will soak 10 amps for a few mins then settles down near 2amps when floating the temps.
