EcoFlow Delta 2 Max - Functionality and App Integration
The Delta 2 Max prioritizes functionality, offering a range of ports, including AC outlets and USB ports, making it easy to charge or power multiple devices at once. This versatility is a big plus for those who need to manage various gadgets simultaneously.

EcoFlow Delta 2 Max - Charging Options
Charging the Delta 2 Max is a breeze thanks to its versatile options. When relying on mains charging alone, the EcoFlow Delta 2 Max impresses with its ability to reach 80% in just 53 minutes, and a full charge takes a little over an hour. This rapid charging speed is a real advantage for users who need a quick power boost without long delays.
In addition to the main AC input, it offers inputs for solar and car battery charging, providing greater flexibility depending on your situation.
Solar energy is a key feature of the Delta 2 Max, supporting dual inputs with a maximum of 1000W solar power. Under optimal conditions, EcoFlow claims you can fully charge the battery in about 138 minutes. Of course, this can vary depending on factors like sunlight strength and solar panel placement.
For those who need an even faster solution, you can combine AC and solar charging, using 1800W from AC and 600W from solar to hit a total of 2400W. This combination reduces the time to reach 80% to just 43 minutes, giving you the best of both worlds in terms of speed and efficiency.
Additionally, you can charge the Delta 2 Max via a car battery using a car charging cable and using the same solar input ports.

EcoFlow Delta 2 Max - Mobility and Transport
Mobility is important, and while the Delta 2 Max does feature integrated handles for easier lifting, its 50.7 lbs (23kg) weight is still a challenge to move frequently. Although the handles help make it more manageable, you might not want to carry it around often without some additional help, like an Ecoflow trolley.
For those who need to transport it for camping or around the house, adding a trolley could make a big difference in ease and convenience.
Real World Performance of The EcoFlow Delta 2 Max (Garage Test)
According to Nick Mokey's review from Digital Trends, the Delta 2 Max handled most of these tasks with ease, though the miter saw did initially trip the system before powering on smoothly afterward. He put the Delta 2 Max through its paces, testing it with a variety of tools commonly found in garages, including a table saw, air compressor, and miter saw.

His tests highlights the power station's ability to maintain a sustained output of 2,253 watts while running both a table saw and a 5HP shop vac simultaneously, showcasing its robust capacity. When really pushed with a space heater and heat gun combo that reached just under 2,400 watts, the Delta 2 Max stood up to the challenge.
In terms of recharging, he notes that while EcoFlow claims the Delta 2 Max offers the “world’s fastest” charging with 1,800W from AC power and an additional 1,000W from solar, in real-world use it pulled a steady 1,590W from the wall. While this falls slightly below the rated 1,800W, it still outpaces competitors, making it one of the fastest in its class.
