10 Best Portable Solar Panels 2026 in the United States

The EF ECOFLOW Solar Generator DELTA2, paired with a 220W solar panel, is designed for those seeking a reliable portable power solution, whether for camping, RV trips, or home backup. One of its standout features is its high capacity and powerful output, allowing you to power a variety of appliances (up to 1800W) without the noise and emissions typical of gas generators. Its LFP battery boasts a long cycle life, ensuring durability and longevity, which is ideal for users looking for a sustainable energy option.

The 220W bifacial solar panel is another highlight, capturing up to 25% more energy, contributing to efficient charging. Plus, with 15 outlets, you have the versatility to connect multiple devices at once. The expandable capacity is also noteworthy, allowing users to extend the system from 1kWh to 3kWh, making it adaptable to different power needs.

The unit weighs 58 pounds, which might be cumbersome for some users, especially during transport. While it does provide fast charging (7x faster AC charging), the initial setup could take some time for those unfamiliar with such systems. Additionally, as a solar generator, its performance is highly dependent on sunlight availability, which may limit its effectiveness in less sunny conditions. The DELTA2 offers a robust and efficient solution for portable power needs, particularly for outdoor adventures or emergency situations at home. While it has a bit of heft and relies on favorable weather, its high output and long-lasting battery make it a worthwhile investment for frequent campers, RV users, or anyone in need of a reliable power source.

The EF ECOFLOW Solar Generators DELTA 2 is a versatile choice for those in need of reliable portable power, especially for camping and home backup uses. With a 1024Wh capacity and an 1800W output, it offers substantial power to keep up to 15 devices running. The fast-charging feature is a highlight, enabling a full recharge in as little as 2.6 hours with three solar panels, or 5.1 hours with two, which is quite efficient for its category.

One of its main strengths lies in its durability, thanks to the LFP battery that boasts a cycle life of over 3000, which means it can last for years. The setup is relatively straightforward, making it convenient for users who need a quick plug-and-play solution. Despite its many outlets and expandable capacity, the unit is quite portable, weighing 27 pounds, which is manageable for most users.

However, there are some drawbacks to consider. The solar panels and power station are shipped separately, which may pose a slight inconvenience during initial setup. The runtime is somewhat limited to about 2 hours, which might not be sufficient for all-day usage without recharging. Additionally, while it is lighter compared to larger generators, some might find 27 pounds a bit heavy for extended travel or transport.

The product's 23% conversion efficiency is decent, although not the highest in the market, but it should suffice for the average user. The durable build and long lifespan make it a sound investment for outdoor enthusiasts or anyone needing a reliable power backup at home. Its versatility in powering a wide range of devices adds to its appeal, ensuring you won't compromise on power needs while on the go.

The Jackery Solar Generator 1000 V2 is a robust option for those in need of portable power solutions, particularly for outdoor activities like camping or emergency situations. With an impressive 1,500W AC output and a 1,070Wh capacity, it can efficiently power multiple devices simultaneously, including larger appliances such as AC units and refrigerators. Its lightweight design at just 23.8 lbs and a foldable handle enhance portability, making it easy to transport.

A standout feature is its fast charging capability, allowing the power station to reach a full charge in just one hour when using the emergency charging setting through the Jackery App. This is beneficial for users who may need quick access to power. The durability of the lithium iron phosphate (LiFePO4) battery is also commendable, promising over 10 years of lifespan while maintaining over 70% capacity after numerous charge cycles.

In terms of connectivity, the generator includes various ports, such as multiple USB-C, USB-A, and AC ports, which cater to different charging needs. The app control feature adds convenience, letting users switch between charging modes and optimize performance. However, there are some drawbacks to keep in mind. While it offers a solid charging capacity, the generator's reliance on app functionality for its fastest charging mode could be a limitation for those who prefer simpler setups. Additionally, while the product ranks well for outdoor generators, it may not be the most powerful option available for heavy-duty applications. Finally, it’s worth noting that the generator and solar panel are shipped separately, which might lead to delays in receiving the complete setup.
