Great product, fast delivery, and everything arrived in perfect condition. I used it for my filament drying box.

It met my expectations! It has already been installed in a product I am using as a prototype and it was highly approved! As advertised!

Have used several of these now. The 12v one was good, reasonable power draw. Needed a lot more heat, though, so have stepped up to 100w 230v and 400w 230v units.
They tend to spike on the inrush, so be prepared to handle at least double the rated wattage when first powered. Make great chamber heaters for 3d printers!

Works great. Already connected it to the 3D printer filament dryer via a thermostat. It heats up like a hairdryer, with a temperature of about 100 degrees Celsius when paired with a 100-watt heater. It heats up to 60 degrees in about 2 minutes easily. And then the economy mode kicks in, that is, it simply turns on and off via the relay.

great
400W/220V, also the fan is 220V
Compact and does what it’s supposed to do… it serves as a camping and travel heater. 💪 😎

220V AC 150W model. As described. Used to heat a 3D printer enclosure for printing ABS. I did not exceed 39 degrees with 30 minutes of heating. A 200W would be necessary.

Everything arrived in good condition, I tested it and it works well. I don’t know for how long. In a closed container, it reached 50°C in less than 5 minutes.

Very satisfied with this one. Put a thicker 24v powered fan on it to use it as a 3d printer chamber heater and this thing overdelivers. Measured around ~450w in steady state and around 750w inrush/heatup with a toasty 180 ° C on the heater core.
Be careful with this heater. Half-ass it and this can definitly burn your house down.

These little heaters work well in my lithium battery box, for cold weather. must be careful to not connect to incorrect voltage or in reverse, else the fan will quit.

I’m genuinely impressed with this product and how well it performs. from the moment i started using it, i noticed how thoughtfully it was designed. it’s simple to use, reliable, and clearly made with quality in mind. the instructions were easy to follow, and i had it up and running in no time. it does exactly what i need it to do, and i’ve already seen improvements in my daily routine thanks to its efficiency. the design is sleek and modern, which is a nice bonus. while it’s not perfect, it’s very close—and for the price, it’s a fantastic value. i would definitely recommend it to anyone looking for a dependable, well-made product that delivers on its promises.

Fast shipping, tested and it’s exactly 400w for 110v . The fan is also 110v . Heat very well , even after i turned off still feel the heat after 1 min . I don’t know if has a protection for overheating. But i like it .

Excellent bit of kit. Very compact. Good air flow. Fan and heater are both 220v making life easier for connecting to power supply. Mind you the plastic casing can get pretty hot so i would recommend over run on the fan. Maybe i should have ordered a lower power than 300w. I intend to use this as a case heater for a 3d printer.

When i received the 12 volt ceramic heater with fan, i connected the heater and fan to a 12 volt battery and in seconds you could feel the heat being blown out

Its working! Very good!! Temperature up to 50 degrees celsius. I recommend two switches, one for the fan , one for the heater, to let cool down the heater with the fan after use. So this wonderful product will last very long

I received the 100W 220V PTC heater within the seller’s stated delivery time. The output temperature is low and unsatisfactory. The current at an ambient temperature of 21°C fluctuates between 445-450mA, which gives a power of approximately 100W.

I bought the 50W version for defrosting car windows, tested it on a table, heats very well, current consumption is 5.6A so it’s quite good, I recommend it for this price.

This was exactly what i was looking for, a simple and cheap way of heating in my van! I tested it as soon as i could and this one says it takes 180watt but instead of 180watt it takes 257watt but thats not a problem for me because i have a small electric heater thats 600watt and i have to connect it through my inverter so thats a lot more usage than this little heater so i’m thinking of building this little heater into my van for when i’m offgrid.

Everything is cleanly processed, cables are reasonably sized, quiet, but gets very hot at the outlet. Higher fan performance (airflow) would be better. I’ll probably get one with less heating capacity and install it.
I am very satisfied!

Unit arrived and works as described. The 50w unit is very low heat output, so be sure to size the unit according to your needs appropriately. I think i should have gone with a higher rating, however, i am sure that i can find a use for this little guy.

It works perfectly, at 12V the total consumption is 5.58 A and the maximum temperature measured of the expelled air is 53 degrees.
