Can You Plug a Space Heater into a Battery Backup?

The question of whether you can plug a space heater into a battery backup is a complex one, and  technical and safety considerations involved. While it is technically possible, it’s crucial to ensure compatibility and follow proper safety procedures to avoid potential damage or hazards.

Understanding Power Requirements

When it comes to powering a space heater with a battery backup, the primary consideration is the power requirements of the space heater and the capacity of the battery backup. Space heaters can draw a significant amount of power, often ranging from 1,000 to 1,500 watts or more. This high power demand can quickly drain the battery backup if it’s not designed to handle the load.

To determine if a battery backup can power a space heater, you’ll need to check the following specifications:

  1. Battery Backup Wattage Capacity: This is the maximum continuous power output the battery backup can provide. It’s typically measured in watts (W) or kilowatts (kW). For example, the BougeRV 1200-2200W Portable Power Station has a maximum output of 2,200 watts, making it suitable for powering most space heaters.
  2. Space Heater Wattage: This is the power consumption of the space heater, also measured in watts (W). It’s important to match the space heater’s wattage to the battery backup’s capacity to ensure compatibility and avoid overloading the system.

Compatibility Considerations

Not all battery backups or portable power stations are created equal when it comes to powering space heaters. It’s crucial to carefully review the specifications of both the battery backup and the space heater to ensure they are compatible.

Here are some key factors to consider:

  1. Wattage Capacity: As mentioned earlier, the battery backup’s wattage capacity must be sufficient to handle the power requirements of the space heater. It’s generally recommended to have a battery backup with a wattage capacity at least 20-30% higher than the space heater’s power consumption to account for potential surges or fluctuations.
  2. Voltage and Frequency Compatibility: Ensure that the battery backup’s output voltage and frequency match the space heater’s requirements. Most space heaters operate on standard 120V, 60Hz AC power, but it’s always best to double-check the specifications.
  3. Continuous vs. Surge Power: Some battery backups may have a higher surge power rating than their continuous power rating. This means they can handle short-term power spikes, such as when a space heater is first turned on, but may not be able to sustain the continuous power draw over an extended period.
  4. Charging and Runtime: Consider the battery backup’s charging time and runtime when powering a space heater. Longer runtimes and faster charging times can be beneficial, especially if the power outage is prolonged.

Safety Considerations

When using a battery backup to power a space heater, it’s crucial to follow proper safety procedures to avoid potential hazards. Here are some important safety tips:

  1. Disconnect When Not in Use: Always turn off the battery backup and disconnect the space heater when not in use. This helps prevent accidental overloading or short circuits.
  2. Proper Ventilation: Ensure that both the battery backup and the space heater are placed in a well-ventilated area, away from flammable materials or combustible items. Overheating can be a serious fire hazard.
  3. Avoid Wet Conditions: Keep the battery backup and space heater in a dry, cool environment. Exposure to moisture or high humidity can increase the risk of electrical hazards.
  4. Monitor for Overheating: Regularly check the battery backup and space heater for signs of overheating, such as unusual noises, discoloration, or unusual odors. If any issues are detected, immediately turn off the system and unplug it.
  5. Avoid Plugging into a UPS: As mentioned earlier, it’s generally not recommended to plug a space heater into an uninterruptible power supply (UPS) system, as this can compromise the UPS’s ability to provide emergency power to critical equipment during a power outage.


In summary, while it is technically possible to plug a space heater into a battery backup or portable power station, it’s crucial to ensure compatibility and follow proper safety procedures. By carefully considering the power requirements, compatibility factors, and safety guidelines, you can safely and effectively use a battery backup to power a space heater during a power outage or in remote locations.
