EcoFlow Delta Pro Review

Designed to handle household appliances and tools, the EcoFlow Delta Pro's large power and battery capacity are equally impressive as its quick charging and dialed display.

Power Output

We measured an AC power output capacity of 3,060Wh, one of the highest of our test group. This is 85% of the claimed 3,600 wh, which is about average for power stations when in AC output mode. You can get even more power if running in DC mode, as less energy is consumed by the inverter.

This is enough power to get most people through a power outage to run household essentials. For example, you can run a typical fridge for over 15 hours with the EcoFlow Delta Pro.

It is rated for a max AC output of 3,600 watts. Allowing you to power most household necessities, such as electric water kettles and space heaters. Though some appliances, such as central air conditioners and electric clothes dryers, will exceed the Delta Pro's output.

The Delta Pro is equipped with AC and DC port options, including a 30A output port, barrel plugs, and an Anderson port. Adding to its impressive list of features and different power capabilities. At first, it can be a little overwhelming to look at all the output and input options. But all the most common output ports are there.

Portability

If mobility is what you are after, the EcoFlow Delta Pro would be low on our list of recommendations. While it was hard to find any other major critiques of this model, the weight and size of this power station are no joke. At 97.24 pounds, this beast of a power station should be used in semi-permanent locations, whether traveling or not. We recommend using two people to lift this power station.

It does have a telescoping handle and wheels, but is best reserved for rolling on even flat surfaces. The built-in handles are sturdy and work well when lifting this station with two sets of hands, but it would be a tough task to lift individually. The shape of the Delta Pro is also unique. A skinnier but longer design, the Delta Pro's dimensions of 25"L x 11"W x 16.5"H can make it tricky to fit into certain spaces, such as in a van build or the closet of your home.

Charge Time

The Delta Pro was a standout in our charge time test. No other power station could charge at its incredible pace of 1,412 Wh/hr. That means we got a full charge in a little over two hours.

The various ways to charge the Delta Pro also stood out. Aside from AC, DC, and solar charging, the Delta Pro can also be charged with a separate EV plug adapter at level 2 charging stations. It also has the option to be charged with a separate 800-watt alternator charger in your car. While these accessories aren't included, the innovative ways to charge this power station add to its impressive list of features.

Features

There are very few features this unit doesn't have. EcoFlow possesses one of the best apps we've used, with every essential setting for both charging and power usage, and it even tracks historical data for you. Its modular design also has the ability to expand up to 25,000 Wh by adding additional batteries and two more Delta Pro power stations. That much capacity could easily power a small home during an outage for over 24 hours. One ding on the Delta Pro is that it only serves as an emergency power supply since its cutover time of 30ms or less isn't quite fast enough to be considered an uninterrupted power supply.

Should You Buy the EcoFlow Delta Pro?

The Delta Pro is an excellent product, but has been updated in many ways by the introduction of the EcoFlow Delta Pro 3, including more power output, higher expansion capabilities, and a 240V outlet. If cost is your main constraint, the Delta Pro is still a strong value, at roughly $1000 less than the Delta Pro 3. If you don't plan to expand your system for home backup capabilities, the Delta Pro may be all you need, otherwise the Delta Pro 3 would be our first choice.

What Other Portable Power Stations Should You Consider?

The natural alternative to the Delta Pro is the new and improved EcoFlow Delta Pro 3. It features a larger battery with improved efficiency and an additional 400 watts of power output. If the large weight and steep price tag are dealbreakers, the Jackery 2000 V2 weighs just 38.9 pounds and produces 2,220 watts of power. While it doesn't match the EcoFlow Delta lineup in home power integration or battery expansion options, two 2000 V2 units will achieve similar power output for less than the cost of a single Delta Pro 3 and only a few hundred more than the original Delta Pro.
