10 Best Portable Solar Generators 2025 in the United States

The EF ECOFLOW DELTA 2 portable solar generator is a solid choice for camping, RV use, or as a home backup power source. It comes with a 1024Wh Lithium Iron Phosphate (LFP) battery, which is known for lasting much longer than typical batteries—up to 3000 charge cycles—so it can reliably serve you for years. It pairs with two included 100W solar panels that have a good 23% conversion efficiency, allowing for relatively quick solar charging. Using two panels, it charges in about 5 hours, and even faster with a third panel if you add one.

This generator offers a strong 1800W continuous output (2700W surge), enough to power most small to medium appliances, and it supports up to 15 devices at once through multiple output ports. That variety is great for different needs while camping or during power outages. Weighing 27 pounds, it’s reasonably portable, though a bit heavier compared to smaller models, so it’s better suited for users who don’t need to carry it long distances on foot.

One standout feature is its expandable capacity—you can add extra batteries to boost storage up to 3kWh, which is useful if you need longer power supply without recharging frequently. The unit also charges quickly from AC power, helping you refill its battery fast when solar isn’t an option. The weight and size might be a bit bulky for some users looking for ultra-light gear, and the solar panels arrive separately, requiring some setup. While it’s built with a durable battery management system for safety and longevity, the generator is priced at a premium level reflecting its advanced features. In summary, the DELTA 2 is best for those who want a reliable, long-lasting solar generator with strong output and expandable options, and are okay with moderate weight and upfront setup.

The BLUETTI Elite 100 V2 is a solid choice if you need a portable solar generator for camping, emergency backup, or outdoor use. Its 1024Wh battery capacity is generous enough to power multiple devices, including four AC outlets that support up to 1800W continuous output with a 2700W surge, which means it can handle heavier devices like small appliances. It supports up to 11 devices through various ports, giving good flexibility for charging phones, laptops, and more.

The 200W solar panel (sold separately) charges the unit fully in about 7 hours under good sunlight, which is quite efficient for solar charging. At 25 pounds and with a compact size, it’s easier to carry around than many other models, especially with the built-in hidden handle. BLUETTI’s build quality feels reliable, and the generator operates quietly at about 30dB, so it won’t disturb your outdoor activities or home environment. One downside is that the solar panel is not included in the base purchase, so that adds to the cost if you want a complete solar setup. Also, while 25 pounds is portable, it might still be a bit heavy if you need to carry it long distances.

The quick switch-over feature during power outages is a useful bonus for home emergency use. If you want a user-friendly, relatively compact solar generator with strong power output and decent battery life, the Elite 100 V2 stands out as a good option, especially if you value silent operation and multiple charging options.

The EF ECOFLOW DELTA 3 is a powerful and versatile portable solar generator with a 1024Wh LiFePO4 battery, offering a robust capacity that suits home backup, camping, and RV use. One standout feature is its incredibly fast charging capability—thanks to its 500W solar input combined with 1500W AC input, it can reach a full charge in just 56 minutes, and 80% in 30 minutes, which is much quicker than many competitors. It supports solar panels (sold separately) and integrates smoothly with EcoFlow's battery expansion system, allowing you to increase capacity up to 5kWh if needed, making it adaptable for longer power needs.

The unit delivers a strong 1800W continuous output (2200W surge with X-Boost), powering up to 13 devices simultaneously, which is great for running multiple appliances during outages or outdoor activities. Durability is another strong point, with a lithium iron phosphate battery rated for around 4000 charge cycles and a 10-year lifespan, plus a rugged IP65-rated battery pack resistant to dust, splashes, and oil.

The DELTA 3 weighs about 27.5 pounds, which is somewhat heavy compared to smaller models, so it's more suited for those who prioritize power and reliability over ultra-light portability. Solar panels are optional extras, so the total investment might be higher if you want a full solar setup. This generator represents an excellent choice for users needing fast recharge times, expandable capacity, and durable build, particularly for reliable backup power or extended outdoor adventures.
