Have you come across Ads for Cosmo Heater online? Does this Portable Heater really work as claimed or is it a scam? Here’s a user report. In this review, I share my experience using this portable heater, its pros, cons, and what you should expect.

Overview Of The Cosmo Heater

Shopcosmoheater.com is the website selling the Cosmo Heater. The Cosmo Heater is a portable heater sold with claims of heating up your spaces like rooms, workplace or your car instantly.

The features include

Testing The Cosmo Heater

I bought this portable heater from shopcosmoheater.com merely because it promised to hit up my room in 2 minutes and they were offering 50% off when you order. Upon receiving my order, I followed the instructions and tutorials to install in in my room.

I placed it in my room which is approximately 25ft square meter but it was unable to heat the room. Just the small area surrounding it, and that was only after almost 30 minutes. So basically, the claims that it can heat up a room in 2 minutes is false.

Honestly, the advertisement is false and deceptive. The heater can only warm you up if you sit very close to it, like one feet close. If you stay two or three feet away, you wouldn’t feel any warmth.

Cosmo Heater Pros: What I Like About It

  1. It is portable
  2. Installing it was pretty easy.
  3. You don’t need to break the bank to buy it

Cosmo Heater Cons: What I Don’t Like About This Portable Heater

  1. Doesn’t produce enough heat for a room.
  2. It is noisy
  3. Energy consumption doesn’t justify the results.
  4. There aren’t any customer reviews about the product online.

Is The Cosmo Heater A Scam?

The Cosmo Heater does not really work as advertised. It can only heat up the surrounding around it and not the entire room. Just like max and heat well heaters it is an ineffective heating solution. It can only heat let’s say up to 5ft sq which is the size of a store and is not suitable for very large rooms or areas with high ceilings.

Also the product is made in China and the website, images and content are all generic and similar to that of the Amigo heater.

How To Use

  1. Plug in your heater and turn it on.
  2. Look at the screen for the temperature.
  3. Decide how long you want it to heat.
  4. Adjust the temperature with the buttons.
  5. If it switches off, turn it off, unplug for 10 minutes.
  6. Don’t use an extension cords.

Where To Buy Cosmo Heater

You can buy this portable heater from their official website Shopcosmoheater.com, they are currently offering 50% discount sales.


The Cosmo heater does not really work as advertised. It does not heat up a room but just the area around it. Honestly, it wasn’t a good value for my money. If I’m to rate this heater, I’ll give it a 4 over 10 just for its size.
