Nezyo 1 Pc PTC Car Fan Air Heater 12v 100w Energy Saving Car Air Heater Constant Temperature Heating

Ok, don't expect this little heater will warm your house! It is only about 100 Watts. Don't expect to to blast out hot air either! It is a Positive Temperature Coefficient (PTC) heater element. That means the hotter It gets, the higher the resistance, and therefore, the lower the current and power in the form of heat! That makes it very safe around combustible materials. From my tests, the output temp seems to max out at about 100 degrees F. So, you're not going to boil water with it but in a small, otherwise cold area like my little chicken coop, it very quietly and safely warms the ladies to my Tstat set temp of 45 degrees when overnight temp drops to 15 degrees. The coop is only about 45 cubic feet. Read more

The heater is not what it says. I plugged both the fan and the heater to a 12v source, and it burned it in seconds. Tried 15v and the heat was barely felt. It works well if you plug the heater straight into a 110V outlet and the fan to a 12V source. I use it to heat up a grow tent. So far so good. I don't know how long it will last. UPDATE: it died after one day Read more

This puts out decent heat although only one side is working. I took off one star because only one side works. Read more

Small but heats up nicely Read more

I gave it 5 stars but it’s total garbage, stopped working after couple of weeks. Don’t buy it! Read more

They work great, but they're not 100w. I put beefiet delta fans on mine and used them for a race car defroster and they work great! Read more

Needed some heat in my trailer to take the cold out. Read more

works well for what it is. According to my shunt monitor, pulls about 150 watts at 13.1 volts on a 100 ah lifepo4 battery. Time to discharge is listed as about 8 hours with full batt. too much power pull to put on a cigarette plug (in my opinion). Really puts out a lot of heat for its size. I plan on mounting this in a small camper for supplemental heating. I will try to update review with thoughts when completed. Of course it is too small for complete heating, but should help some (we will see). Anyway, happy so far, as expected. Read more
