I got this just to see what the safety features were like. There seems to have been a spate of mini heaters being sold that either plug directly into a socket or are designed to be placed on a desk for low level local heating.
Most of the lower power ones seem to use PTC based heaters that self regulate around a small temperature range by increasing their resistance as they get hotter. I wondered what other thermal protection was present inside.
The unit seems to house a very standard looking heater module. It's quite neat that they've fitted it all into an optimal space. The replacement label on the box was wrong. The original data it was covering was correct for power and dimensions.
The fan isn't quite as quiet as the camera makes it seem. There seems to be noise gate that masks lower level noise.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

I have a qeustion is it possible to make the ptc heater less wattage by cutting the ceramic blocks?or just removing one or 2.
I wanna make a tiny heater yo dry silicagel and 3d printer filament
I got it, it works. I bought it for my stray, cat she loves it.
I've got two of these living in an outdoor mini-greenhouse with a DIY thermostat controller to keep it above 15 degrees in winter….so far they have lived semi-outdoors for 2 straight years and are still working. Very impressed!
The ones I find hilarious are the “USB Space Heaters” which take people not electronic savvy by shock when they find out no USB can provide enough current at 5V to provide useable heating.
I do have one of these fans, I just wish the fan was a bit faster. but its very good portable fan if you are somewhere with no heaters and you got a outlet
Cute little device, but I certainly would not take my eyes off it when it’s powered up. Thank you for showing it.
Red…black…sometimes 🙁
It's a shame that such brilliant work gets so trashed. I would imagine the quality dropped, once they got some good reviews. And, of course, they're probably more expensive and available in the 3 pack or 6 pack bundles of low quality units in which they can include and dispose of their defective units. Of course, it's not the fault of their fault. The Chinese were taught the ways of corruption by corporate America, the US SEC and US FDA.
those little motors are the devil. The "bearing" in them wears out in about 4 seconds. Hate hate hate.
Those are centrifugal blowers of squirrel fans
ok, i want one of these heaters. and my ebay is refusing to give me a result with one. anybody got a link for them?
If this had a thermostat to control when it turns on and off, this would be an ideal little thing for sticking in resin 3D printer enclosures. I'm building one from scratch with a little 100 watt PTC heater and it's kinda a pain sourcing some of the parts.
you talking about the fan and it possibly fouling the housing and making a noise reminded me of something that happened some years ago . My ex used to work for a council in the U.K clearing rubbish and taking things from houses for people when they wanted something disposed of . She went to a house and collected a microwave cooker , quite an upmarket one . Instead of taking it to the tip she brought it home for me to take a look at it . Plugged it in and there was a horrendous screeching noise . Out came the screwdrivers , off came the cover and yes , the fan had moved on its shaft . Eased it out , mixed some Araldite , put back together and bingo , we had a microwave . The thing was like new inside and out , hardly used if at all . She collected it from an affluent area so chances are it was bought , plugged in and made the noise so they just bought a new one and threw this one out . Lucky us
How many volts would it take to power the whole device? I saw you mention 2v for the fan, or was that for everything, wanted to connect the thing to a thermostat
Can you adapt this to use with a usb plug?
😂 the information I get from these videos is immense, but the comedy is sometimes just too much. 😂😂😂
