Top Portable Solar Generator
EcoFlow DELTA Pro
Battery Capacity: 3,600Wh (expandable up to 25,000Wh with extra batteries and Smart Generator integration)
Output: 3,600W continuous (surge 7,200W, 4,500W with X-Boost technology)
Recharge Time: 2.7 hrs (AC), 3–6 hrs (solar up to 1,600W), 1.8 hrs with MultiCharge (AC + EV + Solar combo)
Why We Love It:
The EcoFlow DELTA Pro isn’t just a portable generator—it’s essentially a whole-home backup solution. With its massive expandable battery capacity, it can keep an entire household running for days during a blackout. Appliances like refrigerators, air conditioners, washing machines, and even electric ovens can be powered simultaneously without fear of overload. Its LiFePO₄ battery chemistry ensures safety, efficiency, and a lifespan of over 3,500+ cycles before dropping to 80% capacity, meaning it could last a decade or more under normal use.
Another standout is its charging technology. Unlike traditional power stations that take 8–10 hours to recharge, the DELTA Pro supports ultra-fast charging with up to 6,500W input. This means you can recharge in under 2 hours using multiple sources. It also integrates with EcoFlow’s Smart Home Panel, giving you seamless switchover in case of outages. For anyone wanting “peace of mind” backup power without relying on noisy gas generators, the DELTA Pro is one of the best investments in 2025.
Best For: Homeowners who want a complete, all-day (and multi-day) blackout solution and don’t want to compromise on power.

Jackery Explorer 2000 Plus
Battery Capacity: 2,043Wh (expandable up to 12,000Wh with 5 extra packs; 24kWh with 2 units linked)
Output: 3,000W continuous (surge 6,000W)
Recharge Time: ~2 hrs (AC), 2–2.5 hrs (solar with 6×200W SolarSaga panels)
Why We Love It:
The Jackery Explorer 2000 Plus is one of the most modular and expandable solar generators available. While its base 2kWh capacity is good for running essentials during short blackouts, its real strength lies in scalability—you can add up to 5 battery packs and even pair two units together, giving you an enormous 24kWh system capable of running almost anything in your home. The 3,000W continuous output means it can handle multiple appliances at once, from kitchen devices to heaters and power tools.
Despite its size, Jackery designed the Explorer 2000 Plus with portability in mind. It includes wheels and a telescopic handle, making it easier to move around the house or outdoors. Its LiFePO₄ battery is not only long-lasting but also safer compared to older lithium-ion designs. Charging speed is impressive too—fully charging in about 2 hours via AC or solar input. This makes it reliable for both everyday emergency readiness and long-term blackout protection.
Best For: Families who need flexibility, scalability, and strong portable power during blackouts.

Battery Capacity: 2,042Wh (non-expandable)
Output: 2,200W continuous (surge 4,400W)
Recharge Time: ~2 hrs (AC), 2.5–4 hrs (solar with 4×200W panels)
Why We Love It:
The Jackery Explorer 2000 v2 is the streamlined and simplified version of Jackery’s 2000 lineup. While it lacks the modular expandability of the Plus version, it still packs a solid 2kWh capacity that’s more than enough for running refrigerators, fans, laptops, TVs, lights, and medical devices during power outages. With 2,200W output and 4,400W surge power, it can comfortably handle medium to large appliances without tripping. Its portability makes it a favorite among users who want dependable power without the bulk of larger units.
Another advantage is its ease of use and reliability. It charges quickly from AC outlets (under 2 hours to full) and works seamlessly with Jackery’s solar panels for off-grid power. Its lighter weight compared to the Plus model makes it more manageable to move around, making it ideal for smaller homes or apartments. For anyone who doesn’t need expandable capacity but still wants a trustworthy blackout backup, the Explorer 2000 v2 strikes a perfect balance.
Best For: Users who want straightforward, reliable blackout protection without the complexity or expense of modular expansion.
