10 Best Ecoflow Solar Generators 2025 in the United States

The EcoFlow Delta 3 Solar Generator stands out with a strong 1024Wh battery capacity and a solid 1800W power output, making it capable of running multiple devices at once—up to 13 appliances simultaneously. This is especially useful in emergencies or outdoor settings. It supports fast charging with a unique combination of 500W solar input and 1500W AC input, enabling a full charge in just under an hour, which is quite impressive for portable solar generators. The 160W solar panel uses advanced N-Type technology with a high 25% efficiency, meaning it gathers sunlight better than many competitors' panels and is also compact and easy to carry. The battery uses durable LiFePO4 cells, promising a long lifespan of up to 10 years and great cycle stability, which means fewer replacements and better value over time.

Portability-wise, it weighs around 39 pounds and comes with a protective bag, so it’s somewhat bulky but still manageable for camping or RV trips. It offers a variety of outlets including AC and USB-C, covering most charging needs for small appliances, electronics, and even some resistive loads above 2600W when using X-Boost. The system is also expandable, allowing you to add extra batteries to increase capacity up to 5kWh, perfect if you need more power for longer periods.

One drawback is that the solar panel and power station ship separately, which might be inconvenient for some. Also, while the weight is reasonable for its power, it’s not extremely lightweight compared to smaller models, so not ideal if you need ultra-portability. Lastly, the price may be on the higher side, reflecting its advanced features and build quality. For those seeking a reliable, fast-charging, durable solar generator for home backup, outdoor adventures, or RV use, the EcoFlow Delta 3 provides a powerful and flexible solution.

The EF ECOFLOW Solar Generator 3.6KWh DELTA Pro is designed to be a robust home backup solution and an outdoor power source for camping or RV needs. One of its main strengths is the large 3600Wh battery capacity, which can handle high power outputs up to 4500W with the X-Boost technology. This makes it capable of powering most household appliances in an emergency. It also features five AC outlets and a total of 15 various ports, making it versatile for charging multiple devices simultaneously. The generator's smart app control adds convenience, allowing you to monitor and manage charging status and settings remotely via Wi-Fi or Bluetooth.

The included 400W solar panels are highly efficient with a 22.4% conversion rate and are both portable and durable, with an IP68 waterproof rating. However, the generator itself is quite heavy at 99 pounds, which may limit its portability for some users. Another potential drawback is the relatively long recharge time with a single solar panel, which is around 11 hours. For quicker charging, multiple panels are needed, which could be an added expense. Additionally, the generator and solar panels are shipped separately, which might require some coordination for setup.

The DELTA Pro is suited for those needing a powerful and versatile power source with good efficiency and multiple charging options, despite its weight and potential additional costs for faster solar charging.

The EF ECOFLOW DELTA Pro with its 3600Wh battery capacity offers a strong, reliable power source for residential use and camping, making it a solid choice for those needing extended off-grid electricity. It delivers up to 4500 watts of output power, which is enough to handle multiple devices or some heavy-duty appliances simultaneously. The included 400W foldable solar panel lets you recharge the battery efficiently using solar energy, which is great for eco-friendly power and longer outdoor stays.

This unit comes with five power outlets, allowing you to plug in various devices at once, and it supports multiple charging options, including solar, which adds flexibility. However, at 99 pounds, it’s on the heavier side for a portable power station, so while it’s labeled portable, it’s best suited for users who don’t need to move it frequently or over long distances. It runs quietly and without gasoline, making it cleaner and safer than fuel-powered generators.

The size and output make it ideal for camping trips, emergency home backup, or other outdoor activities where reliable power is important. Its weight could be a challenge if you need a truly lightweight, easy-to-carry solution. The ECOFLOW DELTA Pro successfully balances high capacity and power with solar recharging capabilities, making it a better option for users who prioritize power over ultra-light portability.
