1 PCS Room Heater 12V/24V 70W/120W/150W/300W Energy Saving PTC Car Fan Air Heater Constant Temperature Heating Heaters (12V 70W)

It produces a very good amount of heat, but does draw a fair amount of juice , I ran it off a power bank but it should be ran from a reliable source of energy i.e, solar power.

Purchased the 12v/120watt model of heater. the wiring on the device that arrived was a bit off resulting in a 6v - 4a draw (only crossing half the ptc element). Testing the device I can get it up to a full 12v draw across the entire heating elements like advertised but again only 2a draw. I either have a broken device or this isnt a real 120w heating element.

Purchased as an experiment. Have it currently in my vehicle, as extra heat. Plan to use it mainly for defrosting the windshield prior to using vehicle.

This heater does draw about 70 watts are room temperature.Unfortunately it draws more and more power as it gets hotter rather than less power.The device draws more and more power as it heats up until the device's temperature reaches about 220F and the power draw is 95watts. At which point the power draw starts to decrease. It reduces power consumption back to 70 watts at about 250F, 280F is 40 watts

It heats up quickly. No problems with the heating element or fan. Just what I needed.

At 12v this is the best lil heater.

When I forst recieved the heater I connected the heating element to power and not the fan for a few minutes and it got to over 300 degrees F. After connecting to a circuit and running a few times (fan and heater on separate circuits turned on at the same exact time every time.) it's not producing more than a few degrees higher than whatever ambient temperature is regardless where it is at. I went for the 70W knowing that's not a crazy amount, but expected more than 2-3 degrees out of it.

It's small and compact looks to be as described I haven't used it yet though
