10 Best Oupes Solar Generators 2025 in the United States

The EF ECOFLOW Solar Generator DELTA Pro offers an impressive battery capacity of 3600Wh and a robust power output of 3600W, making it a powerful option for home backup, camping, RVs, and emergency situations. With x-boost technology, it can even handle appliances up to 4500W. One of its notable strengths is the inclusion of two 400W portable solar panels, which boast a high conversion rate of 22.4%, ensuring efficient energy collection regardless of weather conditions. This setup allows for a complete recharge in as little as 3.5 hours with three panels or 11 hours with one panel, enhancing its usability in off-grid scenarios.

The generator is also highly versatile with 15 output ports, including AC outlets, USB-A and USB-C ports, DC ports, a car power output, and an Anderson port, catering to a wide range of devices from smartphones to mini fans. Portability is fairly managed despite its 99-pound weight, thanks to the foldable and IP68 waterproof-rated solar panels, which are easy to carry and durable against dust and water. The ECOFLOW app adds to its convenience by allowing remote monitoring and control of the generator’s status and settings.

However, the weight of the generator itself may be a drawback for some users, making it less ideal for those needing frequent mobility. Additionally, while the charging options are versatile, the split shipment of the generator and solar panels could be a logistical concern for users. The EF ECOFLOW Solar Generator DELTA Pro stands out for its high capacity, efficiency, and versatility, making it a reliable choice for various power needs, especially for those who prioritize energy independence and robust power solutions.

The Anker SOLIX F2000 Portable Power Station is a powerful and durable solar generator designed for home use, outdoor camping, and RVs. It has a large battery capacity of 640,000 mAh (2048Wh), which lets you power multiple devices for extended periods. With a strong 2400W continuous output and the ability to handle up to 3600W surge power, it can support high-wattage appliances without risk of overload. The unit offers a wide array of ports, including AC outlets, USB-C, USB-A, and car outlets, allowing you to charge up to 12 devices at once—very handy when you have many gadgets or small appliances running.

It features a lithium iron phosphate (LiFePO4) battery known for safety and a long lifespan, promising up to 10 years of service, which is better than many competitors. Charging is flexible and fast, with a special HyperFlash technology that recharges the battery to 80% in just 1.4 hours via AC or solar input, making it convenient for quick turnarounds during trips. The generator is portable, but at about 67 pounds, it is quite heavy, so it may require some effort to move around. Its rugged build and a 5-year warranty provide confidence in durability and support.

Solar panels are optional, and it is compatible with solar charging, which helps keep it running off-grid. The relatively large size and weight mean it’s less suited for backpacking or very lightweight travel. While it’s powerful and versatile, the price and weight might be more than what casual users need. This model fits best for those looking for a reliable, heavy-duty power source for extended outdoor stays, emergency home backup, or RV use where portability is balanced with high power needs.

The EF ECOFLOW DELTA 2 solar generator is a strong choice if you need a reliable, portable power source for camping, RV trips, or home backup. Its battery capacity is 1024 watt-hours, which can be expanded up to 3kWh by adding extra batteries, giving you flexibility depending on your power needs. It delivers a solid 1800 watts output, enough to run most household appliances quietly and without fumes — a big plus over traditional gas generators. The included 220W bifacial solar panel is designed to capture more sunlight than conventional panels, allowing faster solar charging when outdoors.

One of the standout features is its long-lasting LFP (LiFePO4) battery chemistry, which offers over 3000 charge cycles — that means it should last you many years without losing much capacity. The generator also supports multiple charging methods, including AC wall outlets, car chargers, and solar input up to 500W total, giving you options to recharge in different situations. It has 15 output ports, making it easy to connect various devices simultaneously.

The unit weighs 58 pounds, which is somewhat heavy for a portable generator, so while it’s portable, it’s not the lightest option if you plan to carry it long distances. Also, the solar panel and generator ship separately, so setup might take a little extra effort. If you want a durable, quiet, and environmentally friendly power source that can handle a wide range of devices and last for years, this generator fits the bill. It is especially well suited for outdoor enthusiasts and homeowners looking for backup power who don’t mind the weight and want expandable capacity.
