10 Best Portable Solar Generators 2025 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 Jackery HomePower 3600 Plus is a powerful portable solar generator designed primarily as a home backup solution. It offers a strong 3584Wh lithium iron phosphate (LFP) battery, which is known for safety and long life, supporting up to 6000 charge cycles and lasting about 10 years. This makes it a solid choice for those wanting reliable power during outages or for RV use. The unit delivers 3600W of continuous power, enough to run heavy appliances like heaters and dryers, and it can be expanded with additional units for longer power needs.

It includes 2x 200W solar panels, allowing solar charging in about 4 hours, but you can also recharge it quickly via AC or a gas generator in around 2.5 hours. Its portability is enhanced by a luggage-style design with wheels and a telescoping handle, making it easier to move despite its 77-pound weight—light for its category but still somewhat heavy for casual carrying. Output options include multiple AC ports at 120V, suitable for typical household electronics. The build is durable and features advanced battery protection against overheating, making it safe even in extreme conditions.

A notable downside is that the solar panels and power station ship separately, which could be inconvenient. Also, the size and weight mean it’s better suited for home or RV setups rather than lightweight backpacking or frequent transportation. This generator is an excellent option if you need a robust, expandable, and safe power source for home emergencies or off-grid living but may be overkill if you only need small, portable power for camping.

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.
