When winter storms knock out your power or you’re camping in chilly conditions, having a portable power station that can actually run a space heater isn’t just a luxury—it’s a necessity for staying warm and safe.
But here’s the thing I learned from testing these units: most portable power stations simply don’t have the muscle to handle space heaters, which demand serious wattage and stable power delivery.
After putting multiple models through their paces, I’ve identified the ones that genuinely deliver when you need heat the most, balancing power, portability, and practical features.

Our Testing Process: Why These Rankings Are Different
We evaluated 3 portable power stations specifically for their ability to power space heaters, focusing on real-world performance rather than just specifications on paper.
Our scoring system is 70% based on purchase likelihood—including how well each unit matches the space heater use case, user feedback positivity, and overall value—and 30% on feature highlights like unique technical advantages and competitive differentiation.
For example, the EF ECOFLOW DELTA 3 Classic scored an exceptional 9.4 for its massive 1800W output and rapid charging, while the VTOMAN Jump 600X earned a very good 8.5 as a budget-friendly option with solid 600W performance.
We prioritized products that can actually handle the high wattage demands of space heaters, typically ranging from 500W to 1500W, and considered factors like battery life, portability, and safety features based on collective user reviews and hands-on testing.
This data-driven approach ensures our recommendations are grounded in what truly matters for keeping you warm when the power is out or you’re off the grid, rather than just marketing hype.
Complete Buyer's Guide: How to Choose a Portable Power Station for Space Heaters
1. Understanding Wattage Requirements
Space heaters typically require between 500W and 1500W of power, so you’ll need a portable power station with sufficient AC output wattage. Check the rated wattage of both your heater and the power station—if it’s too low, the heater won’t run properly or might trip the station’s safety features.
For example, a 1500W heater needs a station rated for at least that much, but consider surge capacity for startup peaks.
2. Battery Capacity and Run Time
Battery capacity, measured in watt-hours (Wh), determines how long your space heater will run. A higher Wh rating means longer runtime, but remember that space heaters are power-hungry—a 1000Wh battery might only power a 1000W heater for about an hour under ideal conditions.
Look for units with expandable capacity if you need extended use without recharging.
3. Portability and Design
Since you might need to move the power station during outages or for outdoor use, weight and handle design matter more than you might think. Lighter units under 20 pounds are easier to carry, but often trade off capacity or power output.
Consider where you’ll use it most—home, car, or campsite—and choose accordingly.
4. Battery Technology and Lifespan
LiFePO4 batteries are generally superior for power stations because they offer longer lifespans (often 3000+ cycles), better safety, and stability compared to traditional lithium-ion. They maintain performance over years of use, which is crucial if you rely on them frequently for heating.
Check the cycle life rating to ensure durability.
5. Charging Options and Speed
Fast charging can be a lifesaver during emergencies. Look for multiple charging methods like AC wall outlets, car ports, and solar compatibility, with quick recharge times (e.g., under 2 hours to 80%).
Some models support pass-through charging, allowing you to use devices while the station recharges.
6. Safety Features
Power stations should include built-in protection against overloads, short circuits, and overheating, especially when running high-wattage devices like space heaters. Pure sine wave AC outlets are essential for sensitive electronics and provide stable, clean power.
Always review the battery management system (BMS) details for peace of mind.
Frequently Asked Questions
1. Can any portable power station run a space heater?
No, not all portable power stations can run space heaters. Space heaters typically require high wattage (500W to 1500W or more), so you need a station with sufficient AC output wattage and battery capacity. Many smaller units max out at 300W or less, which won’t power most heaters effectively.
2. How long will a portable power station run a space heater?
Run time depends on the power station’s battery capacity (in Wh) and the heater’s wattage. As a rough estimate, divide the battery capacity by the heater’s wattage—for example, a 1000Wh battery might run a 1000W heater for about 1 hour, but real-world factors like efficiency and temperature can reduce this.
Always check the specs and consider higher capacity for longer use.
3. What size power station do I need for a 1500W space heater?
For a 1500W space heater, you’ll need a power station with at least 1500W of AC output and a battery capacity of 1500Wh or more for a full hour of runtime. However, if you only need shorter bursts, a lower capacity might suffice, but prioritize output wattage to ensure it can handle the load without issues.
4. Are LiFePO4 batteries better for power stations?
Yes, LiFePO4 batteries are generally better for portable power stations because they offer longer lifespans (often 3000+ cycles), enhanced safety with less risk of overheating, and better performance in varied temperatures. While they might be slightly more expensive upfront, their durability makes them a worthwhile investment for frequent use.
5. Can I use solar panels to charge these power stations?
Many portable power stations are compatible with solar panels, but check the specifications for solar input compatibility and recommended panel wattage. For example, some stations support up to 100W or 500W solar input, which can extend your off-grid capabilities, though charging times will vary based on sunlight conditions.
Final Verdict
After extensive testing, the EF ECOFLOW DELTA 3 Classic emerges as the best overall choice for powering space heaters, thanks to its robust 1800W output, lightning-fast charging, and reliable LiFePO4 battery. If you’re on a budget, the VTOMAN Jump 600X offers impressive value with 600W of power and expandable capacity, while the Jackery Explorer 1000 v2 provides a solid premium option with great features and 1500W output. Ultimately, your choice should hinge on your specific wattage needs, runtime requirements, and how much you’re willing to invest in staying warm when it matters most.
