10 Best Portable Solar Generators 2026 in the United States

The EF ECOFLOW Solar Generator DELTA Pro 3 stands out with its impressive 4096Wh battery capacity, which is expandable up to 48kWh, making it highly suitable for extended power outages, home use, and emergencies. Its compatibility with a 400W portable solar panel ensures that it can harness renewable energy efficiently. With a powerful 4000W AC output (scalable up to 12000W), it can power most home appliances, making it versatile for various uses including camping and RV trips.

The numerous charging methods, including solar panels, gas generators, and EV charging piles, add to its versatility and convenience, reducing dependency on fuel. Additionally, the EcoFlow app allows for easy remote monitoring and control, enhancing user experience. The ultra-fast 10 ms switch-over capability ensures a seamless power supply for sensitive devices, which is a significant advantage during power interruptions.

However, the generator's weight of 150 pounds affects its portability, making it less convenient to move around, especially for camping trips. The product's build quality is robust, thanks to automotive-grade LFP cells and IP65-rated battery technology, and it comes with a reassuring 5-year warranty. Despite its quiet operation at just 30 dB, the size and weight could be a drawback for those looking for a highly portable option. Ideal users would be homeowners seeking reliable backup power, campers with larger setup vehicles, and RV owners who can handle the weight. This generator is less suited for those who need a lightweight and easily portable solution.

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 Jackery Solar Generator 2000 v2 is designed to cater to a variety of power needs, from home backups to outdoor adventures like camping and RVing. It boasts an impressive 2042Wh battery capacity and 2200W output, making it suitable for running multiple devices simultaneously. The inclusion of two 200W solar panels ensures compatibility and efficient solar charging, although it takes about 6 hours to fully charge with solar power.

For faster charging, the AC option can power up the generator to 80% in just 66 minutes and a full charge in 102 minutes using the emergency super charging mode. The addition of a USB-C PD 100W port provides quick charging for modern gadgets without the need for extra adapters. Weighing 39.5 lbs, the Jackery Solar Generator 2000 v2 is one of the lightest in its category, thanks to the CTB technology borrowed from electric vehicles. This makes it relatively easy to transport, despite its substantial power capacity.

Durability is a strong suit with its robust LiFePo4 battery, promising up to 10 years of performance, and the advanced temperature control system ensures quiet operation. However, the total shipping weight is listed as 66.8 pounds, which might be a bit on the heavier side for some users. The generator also features a 20ms uninterruptible power supply (UPS) for seamless power during outages, adding to its reliability. While the noise level in silent charging mode is a low 30dB, it still takes up to 5 hours for a full charge, which might be a drawback for those needing quicker turnaround. The Jackery Solar Generator 2000 v2 is a powerful and versatile option for those needing reliable, portable power, with a few considerations regarding weight and charging time.
