Shinic Electric Garage Heater

Shinic Electric Garage Heater

A decent choice for small garage heating but be aware of some issues with its light functionality and power cord length.


  • Efficient dual quartz heating elements
  • Convenient remote control and 5 mode settings
  • Adjustable 90° heating angle


  • Light may not work properly
  • Power cord length is only 6 feet
  • 25W light can be underwhelming

This Shinic Electric Garage Heater is equipped with double quartz heating elements, which ensure quick and thorough heating. It is very convenient to use, thanks to its remote control and 5 different mode settings. The heat output can be easily adjusted to either 750W or 1500W, and the heater even has a halogen light that can be operated separately, providing some illumination to your workspace. The 90° adjustable heating angle also helps distribute heat effectively to where it’s needed most.

However, some users have mentioned that the light may not work properly right out of the box or may be too dim for practical use. The power cord is also only 6 feet long, which can limit installation options in a garage. Additionally, while the lighting feature can be somewhat useful, the 25-watt light output may be insufficient to truly brighten up your garage workspace.

Overall, the Shinic Electric Garage Heater can be a suitable option for heating small garages, but you might need to be prepared to address the light issues and deal with the short power cord. If you can work around these minor drawbacks, this heater could be an effective way to keep your garage warm and comfortable during the cold months.

Additionally, the integrated humidifier and 3D flame effect work together to create a cozy ambiance that’s perfect for those cold winter days. Unlike other heaters that can make the air dry and uncomfortable, this space heater helps maintain a comfortable moisture level while also providing a visually appealing flame effect.

One of the standout features of this heater is its quick heating time. In just 2 seconds, I can feel the warmth radiating from the unit, making it an excellent choice for those looking to heat their small garage in a hurry. The ECO mode is particularly handy, as it helps maintain a consistent temperature and saves energy by automatically turning on and off as needed. However, this heater’s heating coverage is limited to around 220 sq.ft., so if you have a larger garage, you might need a more powerful unit.

Lastly, it’s essential to note that this heater operates at 35 decibels, which can be quiet enough for most people but may be bothersome to others. If you’re particularly sensitive to noise, you might want to consider other options.

In conclusion, the Okoium Space Heater offers an excellent heating solution for a small garage. It’s energy-efficient, versatile, and boasts unique features like the infrared sensor and integrated humidifier. Although it might not be suitable for larger garages or people sensitive to noise, its numerous benefits far outweigh these minor concerns for those looking to enhance their garage’s heating situation.

However, it’s worth noting that the heater’s range is limited to about 4 feet. This means it may not be as effective in extensive spaces or larger garages. Additionally, the on/off switch placement on the bottom back panel can be inconvenient for some users.
