10 Best Small Solar Generators 2026 in the United States

The Jackery Solar Generator 300 is a well-balanced option for those who need a reliable portable power source for camping, outdoor activities, and backup during outages. With a 293Wh lithium battery, it offers a substantial capacity to power small devices and recharge essentials. The 300W power output is adequate for light-duty use, such as charging drones, laptops, and small appliances, making it suitable for outdoor enthusiasts and emergency kits.

The inclusion of a 100W SolarSaga panel enhances its solar compatibility, ensuring you can recharge it using solar energy when off-grid. Additionally, the pure sine wave inverter provides stable power, which is important for sensitive electronics. Weighing only 7.1 pounds and with compact dimensions, it's highly portable and easy to carry in a backpack.

The recharge options are versatile, including an AC adapter, car outlet, and solar panel, providing flexibility in various situations. The build quality is decent, with a durable plastic exterior, although it may not withstand very rough handling. A notable feature is the fast recharge time, reaching 80% in just 2 hours when using both the wall outlet and the USB-C port. One downside could be its relatively modest power output of 300W, which limits its use for larger appliances. Also, the need for separate shipping of the generator and the solar panel may be inconvenient for some users. In conclusion, the Jackery Solar Generator 300 is a solid choice for those needing a lightweight, versatile, and eco-friendly power source for light to moderate use.

The EF ECOFLOW DELTA Pro 3 is a robust solar generator standing out in the small-solar-generators category. Its formidable 4096Wh LFP battery offers substantial energy storage, making it a strong choice for home backup during emergencies or for powering essential appliances, like central AC systems or water pumps, for up to 2-4 days. The generator's 4000W power output, expandable up to 12000W with additional units, supports a wide range of devices, while the X-Boost feature ensures even power-hungry appliances can be energized.

The product excels in solar panel compatibility, including two 400W portable panels, allowing efficient harnessing of solar energy. Its impressive range of seven unique and 18 combo charging options, including AC wall outlets and EV charging piles, provide versatility in how it can be powered, reducing reliance on fossil fuels. While portability is emphasized with a handle design, the generator's weight at 115 pounds may limit mobility, especially for solo travelers or camping trips. However, its silent operation, thanks to X-Quiet technology, is a significant advantage for both indoor and outdoor use, ensuring noise is minimal.

Build quality is robust, with IP65-rated CTC battery pack technology and automotive-grade LFP cells enhancing durability and lifespan. The 5-year warranty and strong customer support further enhance reliability, offering peace of mind to users. One area that might be a concern is the generator's size, which may not suit every space, especially in smaller homes or RV setups. Additionally, while the app-controlled system provides convenient monitoring, those less tech-savvy might find the setup initially confusing. This solar generator is ideal for individuals seeking a powerful, reliable source of renewable energy for home use or extended outdoor activities, though potential users should consider its weight and size before purchasing.

The Jackery HomePower 3600 Plus is a powerful solar generator designed mainly for home backup and emergency use, capable of running household appliances like pumps, heaters, and dryers with its strong 3600W output. It offers a large 3584Wh lithium iron phosphate (LFP) battery, which is safe, durable, and can last over 6,000 cycles, making it a long-term investment. One of its standout features is the ability to expand capacity up to 43kWh by linking multiple units, supporting longer power needs for a small household.

This generator includes two 200W solar panels compatible with the unit, allowing clean solar charging that can fully recharge the battery in about 4 hours under good sunlight. It also supports multiple charging methods — AC, solar, DC, and gas generator — providing flexibility depending on your situation. The inverter supports both 120V and 240V, which means it can handle various appliances safely and efficiently.

Despite its high capacity, the device is surprisingly portable for its size, weighing around 77 pounds but designed with wheels and a telescoping handle, making it easier to move around compared to other heavy generators. Its build quality is solid and reliable, with heat-resistant battery cells that protect against overheating and severe weather conditions. While it is easier to set up than some competitors, the solar panels and power station ship separately, so setup requires an extra step. The weight may still be challenging for some users without help, especially if moving it frequently. The price and size might be more than what casual or very light users need. For those seeking a robust, expandable solar generator to keep essential home appliances running during outages or for RV use, the Jackery HomePower 3600 Plus offers excellent power capacity, safe battery technology, and versatile charging options. However, if portability and budget are your top concerns, lighter or smaller capacity models might be worth considering.
