How the Top Picks Compare
Which charges fastest?
The OUPES Mega 1 leads with a 0-80% charge in just 36 minutes via AC, and a combined AC and solar input can hit 80% in 26 minutes. The EF ECOFLOW DELTA 3 is close behind at 56 minutes for a full charge (80% in 30 minutes). The Apowking, with its smaller 146Wh battery, charges fully in a couple of hours but is far slower in wattage terms.
Which delivers the most power?
The OUPES Mega 1 offers 2000W continuous (4500W surge), enough for large refrigerators plus other appliances. The EF ECOFLOW DELTA 3 provides 1800W continuous (2600W with X-Boost). Both handle most fridges, but the OUPES wins for high-power needs. The Apowking is limited to 100W continuous, suitable only for mini-fridges or coolers.
Which is most expandable?
Both the EF ECOFLOW DELTA 3 and OUPES Mega 1 can be expanded up to 5kWh with extra batteries. The DELTA 3 uses EcoFlow’s ecosystem, while the OUPES uses B2 Extra Batteries. The Apowking is not expandable. For long-term backup, the expandable models are far more versatile. Learn more about expandability in our best portable power stations for home use guide.
Which is most portable?
The Apowking weighs only 3.3 lb, making it the most portable for camping or emergency kits. The EF ECOFLOW DELTA 3 and OUPES Mega 1 are heavier (around 30 lb) but still manageable with handles. If weight is a priority, the Apowking wins, but it sacrifices capacity.
Our Final Picks for 2026
Choose EF ECOFLOW DELTA 3 if you want the best all-around performance with fast charging, solid 1800W output, and expandability to 5kWh. It’s ideal for home backup and RV trips.
View on Amazon.comChoose OUPES Mega 1 if you need maximum power for large appliances or want the fastest recharge speed. Its 2000W continuous output and 36-minute charge make it a powerhouse for demanding scenarios.

Understanding Runtime
To estimate how long a power station will run your refrigerator, divide the battery capacity (Wh) by the fridge’s running wattage. For example, a 1024Wh station like the EF ECOFLOW DELTA 3 can run a refrigerator drawing 150W for about 6.8 hours (1024 / 150 = 6.8). This is enough for overnight backup, but actual runtime varies with compressor cycles and temperature.
AC Output and Surge Rating
Your power station must deliver enough continuous AC wattage to run the refrigerator. A 1500W continuous output is sufficient for most household fridges, but if you plan to power other devices simultaneously, 1800W or more is safer. Also check the surge rating (peak wattage) – refrigerators can draw 2-3 times their running power for a few seconds when the compressor starts. Units with pure sine wave inverters are essential for sensitive electronics.
Battery Chemistry and Lifespan
LiFePO4 (LFP) batteries offer longer cycle life (3000+ cycles) and better thermal stability than NMC. All three top picks use LiFePO4, ensuring years of reliable service. For more on battery types, see our portable power station category guide.

Frequently Asked Questions
Can a portable power station run a full-size refrigerator?
Yes, as long as the station has enough continuous AC output (typically 1500W+) and sufficient capacity (1000Wh+ will run a fridge for 6-12 hours). Models with 1800W+ output and 1024Wh capacity, like the EF ECOFLOW Delta series, are well-suited for this task.
How long will a 1024Wh power station run a refrigerator?
It depends on the fridge’s power draw. A typical energy-efficient refrigerator uses about 100-150W running, so a 1024Wh station could run it for 6-8 hours without recharging. Actual runtime varies based on compressor cycles, ambient temperature, and other loads.
Is LiFePO4 battery safe for indoor use?
Yes, LiFePO4 batteries are among the safest lithium chemistries, with low risk of thermal runaway. They are widely used in home backup power stations and are considered safe for indoor operation when used according to manufacturer guidelines.
Do I need solar panels for a portable power station?
Not necessarily – most stations can be charged via wall outlet, car, or solar panels. Solar panels are useful for off-grid scenarios or extended outages. Some models, like the EF ECOFLOW Delta 2 with solar panel, come as a bundle. For more on solar options, see our best solar power stations for home guide.
