The unit includes three AC ports and a USB-C PD 100W port for fast charging of electronic devices, making it very user-friendly.

The generator offers multiple charging options, including a quick 66-minute AC charge to 80% capacity, and solar charging in about 6 hours with 400W panels, making it flexible for different user needs.

Its LiFePo4 battery ensures durability and a long lifespan of up to 10 years. The generator also features a 20ms UPS function, providing seamless power backup during outages, making it a reliable choice for maintaining power continuity. Despite some minor drawbacks, the quiet operation, eco-friendly performance, and robust build quality make this solar generator a strong contender for those needing a portable and efficient power solution.

The EF ECOFLOW Solar Generator DELTA Pro 3 is a robust and versatile solar generator designed for home use, camping, emergencies, power outages, and RVs. One of its primary strengths is its substantial 4096Wh battery capacity, which can be expanded up to 48kWh, making it capable of providing 2-4 days of backup power for an entire home. The 4000W AC output (scalable up to 12000W) ensures it can power nearly all essential appliances, including heavy-duty ones like a 3-ton central AC or a water pump. This makes it a suitable option for those needing a dependable, high-power solution during outages or off-grid scenarios.

The unit is highly flexible with multiple charging options, including solar panels, AC wall outlets, and even EV charging piles, which means users can recharge it in various situations without relying on fuel. Its portability is enhanced by a handle design, but at 115 pounds, it may not be easy to move around frequently. The generator operates quietly at 30 dB, ensuring minimal disturbance whether used indoors or outdoors. Another major advantage is its quick 10 ms switch-over capability, which ensures uninterrupted power supply to sensitive devices.

The build quality is reliable, featuring automotive-grade LFP cells and IP65-rated battery technology for an extended lifespan and durability. It also comes with a 5-year warranty, which adds peace of mind. However, potential buyers should be prepared for the bulkiness and weight, and note that the generator and solar panels are shipped separately, which may require some patience. This solar generator is ideal for someone looking for a powerful and reliable backup solution for home use or outdoor activities.

The EF ECOFLOW DELTA 2 Max stands out with its large 2048Wh LiFePO4 battery, which is known for a long lifespan—about 3000 full charge cycles—meaning you can expect many years of reliable use. It offers a strong 2400W continuous power output and can handle short bursts up to 3400W, thanks to its X-Boost mode, so it can power nearly all household devices and many high-wattage appliances. This makes it suitable for camping, RV trips, or emergency home backup. The included 220W bifacial solar panel is designed to capture more sunlight by using both sides, improving charging speed and efficiency. It’s also lightweight and foldable, improving portability for outdoor use.

You can charge the generator quickly using AC power or solar panels, reaching 80% charge in just 43 minutes with combined inputs, which is impressive for a solar generator of this size.

It’s built with durable ABS material, and the solar panel has a tough tempered glass surface with IP68 waterproof and dustproof ratings, making the setup robust enough for outdoor conditions.

One downside is the weight—at 71 pounds, it’s not the easiest to carry for long distances, so it’s better suited for car camping or stationary use. Also, the main unit and solar panel ship separately, which may require some patience during delivery. The DELTA 2 Max combines high power, fast charging, and durability, making it a strong choice for those needing dependable portable solar power, though its weight and separate shipping might be minor inconveniences.
