Quick answer: Yes, in the spot where you sit. The CosyJet is a plug-in heater the size of a coffee mug box, with a built-in thermostat and a timer of up to nine hours. It warms your desk, your bedside or a cold corner without switching on the whole-house heating, and it comes with a 30-day money-back guarantee from the official website.

What Is It Like to Use the CosyJet Every Day?
The rest of the house is fine, but your desk, your bedside or the spare room stays cold, and heating the whole home for one corner feels wasteful. The CosyJet is made for that one spot.
Warm hands from the first email
Switch it on beside the laptop, set your temperature and a nine-hour timer, and get on with the day. The heating can stay off.
A cosy hour with a book
It fits on the nightstand next to the lamp. Set the timer for an hour, read in comfort and let it switch off on its own.
It goes where you go
Light enough to carry with one hand to the spare room or the garden office. Plug it in, nothing to assemble.
How Does the CosyJet Work?
A compact heater with a digital display, a built-in thermostat and a timer, in a small body that plugs straight into the wall.
Plug it in
A wall outlet is all it needs. No tools, no assembly.
Set the temperature
Choose a temperature on the small display, and the thermostat holds it for you.
Add the timer
Pick from one to nine hours and the CosyJet switches itself off when the time is up.
CosyJet Pros and Cons
What stands out
- Warms the spot where you sit, so the central heating can stay off.
- A temperature, not a dial. The thermostat holds the one you set on the display.
- Timer from one to nine hours, so it switches itself off.
- Truly compact, the size of a mug box, it fits on a desk or a nightstand.
- Plug and play, with no tools and no assembly.
- Light on electricity, because it only warms your spot.
- Durable, heat-resistant housing and a built-in safety system, as the producer describes it.
- 30-day money-back guarantee on every order from the official website.
Good to know
- Made for your spot, not the whole room. That is what keeps it small, light on electricity and just right for a desk, a bedside or a cold corner.
Who Is the CosyJet For?
- Your desk, your bedside or one cold corner is the problem, not the whole house.
- You want a temperature and a timer, not a dial on the floor.
- You like small gear that sits on the desk instead of under it.
- You want to leave the central heating off while you work or read.
My guides to the best portable space heaters and to space heater vs central heating costs cover the rest of the decision.

I research and write about the small appliances that make a home comfortable: heaters, fans, coolers, humidifiers. I have lived in three badly insulated rentals, so keeping one desk or one bedside warm without heating the whole place is a subject close to my heart.
