A great portable power station with a wide range of appliances

There’s a chance I’ll never give a portable power station a second look. My rationale is that I live in the suburbs of Chicago, and I don’t need that kind of thing. I’m also not so much for camping or outdooring, which reinforces my opinion on PPS. But now that I have moved out of the cities and out of the suburbs towards a more rural setting. I have found that, sometimes, the electricity company is not very reliable. So, having something like a Delta MAX portable power station makes sense. The EcoFlow DELTA Max 2000 is a powerful PPS with many uses.

While there are many PPS on the market, the EcoFlow DELTA Max 2000 fits in the pocket with great portability and power delivery. Some users may find that even the EcoFlow DELTA Max 2000 doesn’t fit their power needs, but I think many more will find that it works well. Even if you are an urban dweller, this portable power station can serve you well. Read on for the full review!

One thing you can’t call the EcoFlow DELTA Max 2000 is lightweight. But, I can say it’s not too heavy to not move. EcoFlow designed the DELTA Max 2000 to be portable, so they keep the weight at less than 50lbs. Although I can pick it up with one hand, I suggest using both hands and balance the weight to avoid hurting yourself.

The unit has a two-tone gray and is made up of different materials, with the dominant material being high-quality plastic. The top has two wide and sturdy handles to carry the unit around. I think the company missed an opportunity to add a wireless charging pad or two on top, because there was nothing else there.

On the left side of the unit, you’ll find two fans for keeping the batteries cool. On the right side of the unit, you’ll find two more fans and two battery extension ports. These ports allow two more EcoFlow portable power stations to be daisy-chained together. So you can have three EcoFlow DELTA Max 2000 units interconnected to provide a ton of power.

You can see a lot going on on the back of the EcoFlow DELTA Max 2000. Above is a flap that opens to reveal the solar/car charging input port, AC charging speed switch, X charging input port -Stream AC, and the overload protection switch.

Just below it, you’ll find six AC output sockets, all with ground capability and the AC power button. Finally, there are two DC5521 output ports, a 12V DC power button, and a car (cigarette) outlet covered by a flap.

Finally, you’ll find a bright and clear LCD on the front and a few more handy ports on the bottom. It includes two USB-A ports, two fast-charging USB-A ports, and two USB-C 100W ports. There are also two more buttons; one controls the power of the unit, and the other controls the USB power.

The LCD has a variety of useful information, below is a diagram of what you can expect to see on this display.

Overall, the design is nice and sleek. There are a ton of useful ports, and the LCD gives you a plethora of important data. The EcoFlow DELTA Max 2000 isn’t exactly lightweight, but it’s lightweight enough for a person to carry and move. The design is pretty good, though my main beef is that a wireless charging pad is a great addition to the top.

Ease of Use

The EcoFlow DELTA Max 2000 is not difficult to use. There is very little setup to be done despite the included app. Plug it into your wall, charge it fully, and then plug something else into it to make everything work. You can purchase optional solar panels that can charge the unit by the day. We didn’t get that option, so we can’t say how that works.

As for the app, it’s something we haven’t tested. Unfortunately, the app connects via Wi-Fi and requires a 2.4GHz network. I have a 2.4GHz network and a 5GHz network running, but for some strange reason, 2.4GHz smart devices like the EcoFlow DELTA Max 2000 don’t play with it. This is not an issue with EcoFlow; this is an issue of my ISP, so I didn’t score the app because I can’t use it.

You can find the complete user guide for the EcoFlow Delta Max here if you want to take a look at its features and get a more detailed peek at all its buttons and ports.

Overall, the DELTA Max 2000 is simple to use without the app, and as far as I can tell, the app looks pretty straightforward and lets you see your power consumption from your mobile and not have to look at the unit itself .


Performance requirements for everyone will vary, and I think the EcoFlow DELTA Max 2000 will handle almost any scenario. I did not experience any loss or emergency need for power during my test, so I passively tested the devices here and there.

Laptops, smartphones, headphones, toaster ovens, rice cookers, and Milwaukee Sawzall are just a few of the things I plug into the DELTA Max 2000. I use multiple devices at once, and the DELTA Max 2000 seems to keep up. no glitch.

I think the EcoFlow DELTA Max 2000 would be a great power source for remote work that requires wired power tools, such as the Sawzall. It can also serve as a power station for battery packs of tools. I don’t make tools very much, but I do have a few jigsaws that require power, and I’ve used those jigsaws with shorter extension cords because of the DELTA Max 2000.

We don’t have a lot of power -hungry devices around the house, but I threw a lot at the DELTA Max 2000, including things I don’t usually use together, and it handles everything without a problem. You can also plug your refrigerator into this thing if the power outage is too long.

If you choose solar panels, you can keep the DELTA Max 2000 charged indefinitely while it powers whatever you plug into it.

Overall, I have nothing to throw at the DELTA Max 2000 that it can’t handle. I’m sure everyone’s situation is different, so there may be a case that it might not be handled, but it passed with a bright color in our test.

Battery Life

The EcoFlow DELTA Max 2000 has a capacity of 2,016Wh, that’s big. It provides AC and DC power at 120V (US) or 220-240V under 20 amps. Adding two more units via the battery extension ports will give you 6,048Wh of power. But let’s stay in one unit because that’s what EcoFlow sent us.

Actually, we did different tests over a week at different times and we didn’t exhaust the DELTA Max 2000. Each use case will vary from one another, so we cannot say exactly what the battery life will be.

Overall, we can say the battery life is very good for us, and the fast charging feature powers the unit very fast.


EcoFlow DELTA Max 2000 review: A great portable power station with a wide range of uses

I wouldn’t wear it; the EcoFlow DELTA Max 2000 is expensive. The MSRP of this unit is US $ 2,099, and that is big money to pay. The company operates specials, and currently, in this review, they are pricing the unit at US $ 1,899.

While the price is high, I think the value is there. There are so many uses and scenarios that it can be useful because I think it can pay for itself quickly in just a few uses.


The EcoFlow DELTA Max 2000 is not a purchase for everyone. It’s a lot of money to invest, and it’s obviously to be apprehensive. But I think this portable power station is an important tool, and it’s one of those things that might not come in until it happens. Backup power is never a bad idea, and the DELTA Max 2000 is a very bad unit you can count on.
