The EF ECOFLOW Solar Generator DELTA 2 Max is a solid choice for camping and outdoor use thanks to its large 2048Wh battery capacity, which lets you power most household devices for hours. It offers up to 2400W continuous output and can briefly handle up to 3400W with its X-Boost feature, so it can run many appliances including some higher-power ones. With 15 output ports, you can connect multiple devices at once, which is great for group camping or RV setups.
One big plus is the fast charging time: it can reach 80% charge in about 43 minutes using combined solar and AC power, and about 1.1 hours on AC alone. The included 220W bifacial solar panel captures sunlight from both sides and is quite durable and water resistant, rated IP68, making it reliable for outdoor conditions. The station itself uses a LiFePO4 battery that promises around 3000 full charge cycles, meaning it should last more than 10 years with regular use.
On the downside, the power station weighs 71 pounds, which makes it less convenient for backpacking or long hikes. Though the solar panel is lighter and foldable, the overall setup is best suited for car camping or RV trips where weight is less of an issue. Also, the generator and solar panel ship separately, so you might need to wait to get everything together. If you want a powerful, fast-charging, and durable solar generator primarily for campsite or RV use where you can handle the weight, this unit is a strong contender.
The EF ECOFLOW Portable Power Station Delta 2 is designed specifically for outdoor enthusiasts, making it a great fit for camping and RV use. With a substantial battery capacity of 1024Wh and the ability to output 1800W, it can power a variety of appliances, which is a major advantage. This means you can keep your essential devices running without the noise and fumes of a traditional generator. One of its standout features is the rapid charging capability, reaching 80% in just 50 minutes, which is incredibly useful for those in need of quick power restoration.
Another notable strength is its expandable capacity, which allows users to connect additional batteries to increase total output to 3kWh. This flexibility is particularly appealing for longer camping trips or off-grid living. The inclusion of multiple output ports (15 in total) caters to a wide range of devices, enhancing its versatility.
The unit weighs 27 pounds, which may be cumbersome for some users seeking ultimate portability. While it’s designed for durability and has a long battery life thanks to its LiFePO4 chemistry, it may not be as rugged as some dedicated outdoor equipment. Additionally, it supports solar charging with up to 500W input, but solar panels are sold separately, which could add to the overall cost.
The EF ECOFLOW DELTA 3 is a robust portable power station well-suited for camping and outdoor activities. It offers a strong 1024Wh LiFePO4 battery that supports up to 4000 charge cycles, promising a long lifespan of around 10 years which is exceptional for this category. With 1800W continuous AC output and surge capacity up to 2200W (3600W with X-Boost), it can power multiple appliances simultaneously—up to 13 devices at once—covering needs from small gadgets to heavier equipment like mini-fridges or power tools.
Charging is a standout feature, with the ability to fully recharge in just 56 minutes using AC or solar inputs, which is impressively fast and handy for quick turnaround times on trips. The unit supports 500W solar input (solar panel sold separately), offering eco-friendly recharging options. Port-wise, it includes several AC outlets and USB-C ports, making it versatile for various devices. Weighing about 12.5 kg (27.5 pounds), it is portable but not the lightest option for backpackers; however, its compact dimensions make it manageable for car camping or RV use. The build quality is strong with an IP65-rated battery pack, meaning it’s splash, dust, and oil resistant, which adds confidence for outdoor environments.
On the downside, the weight and size may be cumbersome for those seeking ultra-light gear, and the solar panels needed for optimal off-grid use are sold separately, adding to the initial cost. Also, while 1800W output is sufficient for most camping needs, it may fall short for very high power demand appliances without the extra battery expansion. In summary, the DELTA 3 suits campers and RV users looking for a powerful, durable, and fast-recharging power station that can handle multiple devices simultaneously, with the bonus of long battery life and weather resistance. It balances strong output and smart features well but is better for vehicle-based camping than lightweight backpacking.
