Our Verdict
This is a 12V car heater, not a home space heater. It plugs into your cigarette lighter and draws only 150W. Home heaters use 1,500W to warm a room.
The dual-mount design gives you two options. Stick it to the windshield with the suction cup or set it flat on the dashboard. The 90cm cord reaches most sockets without pulling tight.
It runs in two modes: heat and fan. You can use it in winter to defrost and in summer to move cool air. Both modes work through the same compact unit.
Two key safety features are absent. There is no tip-over protection and no overheat shutoff. Most competing car heaters include at least one of these.
At $19.99, the price is very low. For light defogging and mild cabin warming, it can help. Do not expect it to handle serious cold-weather heating on its own.
What We Like
- Uses only 150W of power. Your car battery stays protected during use.
- Costs just $19.99. This is one of the lowest prices for any car heater.
- Mounts two ways: suction cup on windshield or flat on the dashboard.
- Runs in heat mode and fan mode. You can use it in winter and summer.
- The 90cm power cord reaches most cigarette lighter sockets with ease.
What Could Be Better
- No tip-over protection. The heater keeps running if it falls while driving.
- No overheat shutoff. The heater does not stop if it gets too hot.
- Only 150W of output. Most space heaters deliver 1,500W, which is 10 times more.
- No timer. You must remember to turn it off manually every time.
- No remote control. You must reach the unit to adjust settings while in the car.
