Ecoflow is a company founded in 2017 that specializes in portable power stations and renewable energy solutions. Their goal is to make reliable, clean power accessible to everyone.
Portable power stations are all-in-one portable battery packs that can power your devices and appliances on-the-go or serve as emergency backup power. They have built-in lithium batteries, an inverter to provide AC power, and outlets to plug in devices. Many also have solar charging capabilities.
Portable power stations provide a compact, portable alternative to heavy gas-powered generators. They produce no emissions, make very little noise, and the batteries can be recharged via solar panels or by plugging them into an outlet. This makes them ideal for camping, RVs, emergency power, and more.
Compared to traditional generators, portable power stations tend to be much lighter and easier to move around. They can’t provide as much continuous power as a high-wattage gas generator, but they can run smaller appliances like mini-fridges, CPAP machines, and electronics. The built-in batteries provide hours of power depending on the station’s capacity.
When shopping for a portable power station, key factors to consider are:
- Wattage – Determines how many devices you can run at once.
- Battery capacity – Measured in watt-hours, determines how long it will run.
- Outlets – AC, USB, 12V DC, and solar input allow flexibility.
- Weight – Important if you’ll be moving it around a lot.
- Price – Budget portable models start under $200, premium models run $1000+.
For those looking for sustainable backup power, portable solar generators provide the ultimate in renewable energy solutions.

Real-World Power Testing
We put the Delta Max through a series of real-world tests to see how it would hold up to typical homestead chores.
First, we used it to transfer 300 gallons of water from a tank to our large storage container using a 1/2 horsepower transfer pump that drew around 1000 watts. The Delta Max handled this task for about 15-20 minutes before the battery level dropped to 74%.
Next we fired up our cement mixer to make batches of dirt and Portland cement for an earthbag chicken coop project we’re working on. With the mixer running empty it used around 220 watts, but jumped to 300 watts once we added material. Over the course of a few hours work, the foldable 220 watt solar panel Ecoflow sent us was able to keep the Delta Max charged up during cement mixing days.
Looking to take a break, we blended up some icy frappuccinos using a Ninja blender plugged into the Delta Max. The blender surged to 1500 watts but averaged around 800 watts during blending. We had enough juice left in the Delta Max to make many more blended drinks.
To wrap up our testing, we took advantage of the various USB charging ports to charge up devices like phones, tablets, and wireless earbuds. The USB-C ports in particular were great for larger devices like tablets. After a full day of testing the Delta Max, we ended up around 63% battery after charging various devices.
Overall, the Delta Max provided plenty of power for real-world homestead chores, with the battery holding up nicely even under high-draw appliances. The versatility of the AC, DC, and USB ports was also great for charging a range of devices.
Charging the Delta Max
The Delta Max 1600 can be charged in several ways for maximum flexibility. For solar charging, it can accept up to 800W of solar input. This allows it to charge in 1-2 days from a solar panel when used moderately.
