Ecoflow Delta Pro vs Max

There are lots of reasons someone might need a stand-alone power station. For some, it’s a hepful tool for road trips, traveling, and outdoor entertaining. For others, they provide peace of mind that you’ll have power even in an emergency, or are a way to supplement your home’s power with renewable solar energy. If you run pop-up shops, or work as a contractor or tradesman, a portable generator is a must-have for running equipment out of the range of car or wall outlets.

Each of these groups of people has their own needs and requirements for their power generator, and that’s ultimately what will determine your best option if you’re comparing the Ecoflow Delta Pro vs. Max (>>> Check on Ecoflow). Keep reading to see where each of these power stations excels and decide which one will best meet your power needs.

Power Per Charge

The battery in the Ecoflow Delta Max has a capacity of just over 2,000 watt hours per charge. For context, that’s enough to run a 40-watt device like a CPAP machine for 30-35 hours, or a 1,000-watt device for about 2 hours.

The Ecoflow Delta Pro has a capacity of 3,600 watt hours per charge. That translates to about 50 hours of run time for 40-watt devices, or 3-4 hours for 1,000-watt devices.

More power per charge: Ecoflow Delta Pro

Ports and Devices

Both the Delta Max and Delta Pro have 15 charging ports. The Delta Max has an extra AC outlet, while the Delta Pro adds an Anderson Port, while they have the same number of USB and DC options.

In this category, the Ecoflow Delta Pro has just a slight edge thanks to its higher power output. It can put out 3,600 continuous watts, or up to 7,200 watts of surge power, compared to the 3,400 continuous watts of the Delta Max.

Portability

The Ecoflow Delta Pro is a hefty power station. While it’s still portable enough to fit into a car trunk for transportation, it weighs over 80 pounds, so you’ll likely want two people to load and move it. The Ecoflow Delta Max is much lighter at 48 pounds, as well as more compact overall, making it much easier to move, carry, and transport on your own.

Recharging Time

Both of these power stations can recharge very quickly for their high capacity. You’ll need around 3 hours to recharge the Delta Pro using a wall outlet, or even less if you’re using an electric vehicle charging station. For recharging at home, though, the Delta Max is faster, going from empty to 80% capacity in just over an hour using a standard wall outlet.

Ecoflow Delta Pro

Ecoflow Delta Pro

The high capacity and power capability of the Ecoflow Delta Pro makes it an ideal option for emergency preparedness, off-grid living, and mobile professionals. With one generator, you can run a full-sized refrigerator for 24 hours, or run heavy-duty equipment like air conditioners, electric power tools, or electric ovens and deep-fryers for 2-3 hours. You can also link multiple generators together to expand their total capacity and run all the devices in your home in the case of a power outage.

Considering its power, the recharging time of the Ecoflow Delta Pro is nothing short of remarkable. The fastest recharging option is an EV charging station, which can fill the generator in less than 2 hours. You’ll get a similar recharging time by combining AC and solar panel recharging. Even if you’re just using a wall outlet, though, you can recharge it in around 3 hours. Its solar panel recharging is also very efficient, especially if you use a full 1,600-watt array.

It’s also easy to control and monitor the Ecoflow Delta Pro. It links to the EcoFlow app so you can easily track your energy use. For whole-home power, you can connect it to the EcoFlow Smart Home Panel, linking your generator directly to your home’s circuits for uninterrupted power even during blackouts. RV-ers will also appreciate that it has a dedicated 30A Anderson port, in addition to its array of AC, USB, and DC options, all of which can be used simultaneously.

Pros

  • Capable of running heavy-duty appliances and tools
  • Expandable power capacity
  • Fast device charging through quick charge USB-A ports
  • Fast recharging through wall outlet or EV charging station
  • 5 ways to recharge
  • Connects to Smart Home Panel and EcoFlow app

Cons

  • Large and heavy
  • Higher cost


Ecoflow Delta Max

Ecoflow Delta Max

The Ecoflow Delta Max strikes an impressive balance between portability and power. It can put out nearly as much continuous power as the Delta Pro but is more compact and weighs almost 40 pounds less. Most people will be able to carry it on their own using the built-in handles, while its smaller size makes it a better choice for travelers and campers.

The Ecoflow Delta Max comes with the cables to recharge it through a wall outlet or car charging port. You can also connect it to solar arrays up to 800 watts. Its advanced MPPT system adjusts the current and voltage in real time to maximize solar charging efficiency, even on cloudy days, and it can be fully recharged using solar panel in around 3 hours in ideal sun conditions. It also recharges quickly through AC outlets or a smart generator.

All 15 of the charging ports on the Delta Max can be used simultaneously, with a total output of up to 2,400 watts through the AC outlets, or up to 3,400 watts total using the X-Boost function. It recharges devices quickly, too, especially if you use the two quick-charging USB-A ports. While its capacity is lower than the Delta Pro, it can still run 60-watt devices like mini fridges for up to 66 hours, or recharge a laptop more than 30 times. It won’t give you as long of a run time for more power-hungry devices, however. If you’re powering a 2,000+-watt device like a space heater, you’ll only get about an hour of power before you need to recharge the generator.

Pros

  • Fast-charging with AC X-Stream (0-80% in 65 minutes)
  • Recharges through solar panel, generator, AC outlet, or car port
  • High enough output for heavy-duty appliances
  • Expandable capacity
  • Monitor and control using EcoFlow app
  • Excellent power to weight ratio

Cons

  • Doesn’t last as long per charge as the Delta Pro
  • Long recharging time through car ports (up to 21 hours)


The Verdict: Ecoflow Delta Pro vs Max

Choosing between the Ecoflow Delta Pro and Delta Max ultimately comes down to how much power you need and where you’ll be using it. The easy home integration of the Delta Pro makes it a top choice for back up or emergency power, and its large size won’t be a concern in these in-home uses (>>> Check the current price on Amazon). The Pro is also the better option for professional uses since it can power more devices for longer.

On the other hand, the Ecoflow Delta Max has plenty of power for most on-the-go uses, and is much easier to transport from place to place. It’s also about half the price of the Delta Pro, making it the better value if you don’t need features like EV charging or home integration. We hope this comparison has helped you figure out which model will serve your needs the best!
