They are called Livington Handy Heater, PowerHeater, Ultraheat Pro or InstaHeat - small mini heaters that supposedly do great things: in just a few minutes they are supposed to warm up rooms more than conventional heaters.
Is that even possible? Let's take a look at the devices and the sites that sell them!
The promises
It is almost impossible to browse the Internet without coming across advertisements for mini heaters, whether on websites:

Or on Facebook:

The performance statements of the various devices are very similar, which is why we are listing the promises of the “UltraHeat Pro” device ( HERE , archived HERE ) as an example:
- Always 50 percent discount “for a short time” (59.95 euros instead of 119.95 euros)
- A room of 23 square meters becomes 37 percent warmer in just a few minutes
- The device has always been featured by major media outlets
- It should be able to heat rooms up to 250 square meters (!) (probably a translation error, 250 square meters would be 23 square meters)
The price
The mini heater, which presents itself as a novelty, has been around for several years. It's supposed to cost just under 60 euros when discounted, and on some of the sites it's "only" 50 euros, but it's also much cheaper:

The exact same devices can be found on Amazon in the range of 30 – 45 euros.
In the screenshot above you can only see that one of the devices received reviews - which is because a lot of the devices were put on Amazon by new dealers, often from China given the names.
The reviews
It's always the same thing with reviews on Amazon: You should never rely on the total number of stars given, because the bad reviews often reflect the more honest experience about the devices:
Many users say what you can imagine given the size of the mini heater and the performance: Suitable only for very small rooms (e.g. bathroom) up to 8 square meters in size (heating effect: 0.2 degrees in 1 hour), stinks Plastic, very warm only directly in front of the device, risk of burns if touched during operation.
The reviews on the site's homepage are of course much more positive. Let’s take a look at the reviews of “Patricia” and “John”:

It's funny enough that they both say the same thing, "Patricia" in English and "John" in German. It's even funnier if you search for them using the photos:

Stock photos were simply used for all positive reviews - the people are not real customers, so the reviews are probably fictitious!
The page
Let's stay on the frequently advertised UltraHeat Pro page, although very similar things were discovered on the other pages.
What is very annoying is that the site always wants to open a phishing page with cryptic names, which in my case Avira warns about:

Now I just want to buy a device like this anyway - and luckily I can do that via PayPal, but puff cake:

The only payment options available for the mini heater are credit card, instant payment or Google Pay - i.e. only payment options that I cannot revoke!
The site's imprint to find out who to contact if the mini heater is perhaps defective doesn't help either: you are redirected to another site called "ecomerz pro", which is based in Madrid.
And this company doesn't have any good reviews: In on “Fraud Alarm” (see HERE ) about an inferior smartwatch that was sold at an overpriced price - similarities with the current, overpriced mini heater are certainly no coincidence!
The age of the site, like some other sites with the mini heater for the socket, does not inspire confidence either: it was only created on August 22nd , by the cloud service “Acens” – the real owner of the site is not listed.
Let's summarize
- The promises are far exaggerated: heat a 23 square meter room by 37 percent in just a few minutes? This would mean, for example, that a room with a temperature of 18 degrees would be 24 degrees within a few minutes - not even conventional heaters can achieve this!
- The price is exorbitantly excessive; you can get identical devices for a third of the price on Amazon, for example
- The (of course only positive) reviews on the homepages are fake
- PayPal is advertised as a payment option, but is not available when ordering
- The company is based abroad and has received bad reviews for overpriced products in the past
In the end, we have a mini hairdryer for the socket that actually gets hot in the immediate vicinity, but with its 500 watts it cannot physically heat up a medium-sized room that much in a very short time - according to experience reports, not even a very small room.
So you can't say goodbye to heating costs with this device, even if the advertising for the mini heater promises this.
Also interesting: Due to the looming gas crisis, many people are wondering whether there are alternative heating options.
One of these is supposed to be tea light ovens - but their heating effect is rather homeopathic. – The tealight oven with flower pots – Not really a real heater
