10 Best Portable Solar Generators 2025 in the United States

The Jackery Solar Generator 1000 v2 is a strong choice if you’re looking for a reliable and efficient portable power source for camping, emergency backup, or off-grid living. It offers a large 1,070Wh LiFePO4 battery, which means it can power many household essentials for hours. The standout feature is its fast charging capability—going from empty to full in about 1 hour using the included 2 x 100W solar panels or AC power. This is much quicker than many other portable solar generators. You get a good range of output ports, including 3 AC outlets and USB-C fast charging, which lets you charge multiple devices at once without needing extra adapters.

Weighing just under 24 pounds with a compact design and ergonomic handle, it’s reasonably portable, but still a bit heavy compared to smaller units. The solar panels are foldable and lightweight, making them easy to carry along. The build quality is solid, featuring UL certification for safety and a durable ABS case designed to handle outdoor use. The system’s smart app control lets you monitor and customize charging, adding convenience.

On the downside, while the 1,500W power output can handle most home devices, it might be too much or too heavy if you only need a small power supply. Also, the solar panels and generator are shipped separately, so setup might take a bit longer. This model suits those who want quick charging, longer battery life, and versatility in a portable generator but are okay with carrying a bit more weight for these benefits.

The EF ECOFLOW Solar Generator DELTA Pro with a 400W Portable Solar Panel stands out with its ultra-powerful 3600Wh battery capacity, making it a robust option for home backup, camping, or emergencies. It offers a substantial 3600W AC output, with an impressive 4500W peak using x-boost technology, allowing it to power various household appliances. This makes it suitable for users requiring reliable power during outages or outdoor activities.

The generator has a variety of 15 output ports, including 5 AC outlets, USB ports, and DC ports, providing versatility in charging and powering multiple devices simultaneously. The solar panel boasts a high conversion rate of 22.4%, ensuring efficient energy capture even in less than ideal weather conditions. It can fully recharge the generator in as little as 3.5 hours when using three panels, or 11 hours with a single panel, though the latter can be a lengthy wait in urgent situations.

One of the considerable advantages is its durability and portability. Weighing 99 pounds, the DELTA Pro is relatively heavy, but the 400W solar panel is more manageable at 35.3 pounds and is foldable and water-resistant, making it a practical choice for outdoor use. The smart app control feature adds convenience, allowing users to monitor and adjust settings from afar via Wi-Fi or Bluetooth. The charging time of up to 1.8 hours with a 240V outlet is quick, but the wall outlet charging time of 2.7 hours might be slower for some users' needs. Despite these drawbacks, the EF ECOFLOW DELTA Pro is a feature-rich, powerful, and efficient solar generator suitable for a wide range of residential and outdoor applications.

The EF ECOFLOW Solar Generator DELTA 2 Max is a robust and versatile portable power solution, ideal for camping, RV trips, and even home power outages. Its battery capacity of 2048Wh and powerful 400W solar panel make it a strong contender in its category. The fast charging capabilities are impressive, allowing it to reach 80% charge in just 43 minutes using both solar and AC inputs, or in 1.1 hours with AC only. This makes it highly efficient for quick power-ups in various situations.

The inclusion of multiple output ports (15 outlets) means you can power almost any household device, and with the X-Boost mode, it can handle high-wattage appliances up to 3400W, adding to its versatility. The upgraded LFP battery offers a long lifespan with over 3000 charging cycles, which is significantly above industry averages, ensuring durability and cost-efficiency. The lightweight, waterproof solar panels are built to withstand outdoor conditions and are easily portable at 35.3 pounds.

However, the weight of the generator (86 pounds) may make it less convenient for frequent transportation. The smart app control adds convenience by allowing you to customize charging times and monitor the battery status, though it may require some initial setup and learning to use effectively. In terms of durability and build quality, the DELTA 2 Max is designed to endure rugged outdoor use, but its high price point might be a consideration for budget-conscious buyers. This portable solar generator is perfect for those looking for a reliable, fast-charging, and high-capacity power solution for both outdoor activities and emergency home use.
