I’m presently amassing energy vegetation so I had the RIVER 2 MAX, Professional, DELTA 2 and the Jackery Explorer 2000 Professional available after I took these photographs. It provides you an thought of ​​the full measurement of every unit.

For me, the principle factor is that the RIVER 2 Professional is nicely proportioned, not a lot larger or heavier than the MAX, however with further ports, extra capability and better energy output.

As a lot as I really like the DELTA 2, I discover it a bit impractical as a consequence of its measurement and weight while you need one thing a little bit extra portal.

The Jackery is a very totally different beast. It’s moveable within the sense that I can choose it up. That’s all. It is big and cumbersome to move, but it surely packs an enormous capability and the 2200W output means it could actually deal with many high-power home equipment like kettles or deep fryers.


After I checked out the EcoFlow RIVER 2 MAX, I could not get it to work correctly with the app as a result of it hadn’t been formally launched, but it surely was with the Professional.

Having an app for an influence station could seem pointless and also you in all probability will not use it a lot, however there are some helpful options.

  • You’ll be able to see the present enter/output for AC/Photo voltaic/USB and so forth.
  • Battery share and remaining life are based mostly on present utilization
  • You’ll be able to regulate the add pace. Usually I would go away it at full pace, however a slower charging pace will imply the followers spin much less and is a bit higher for the battery.
  • You’ll be able to change the enter amps of the cardboard; I assume this will probably be largely useful to your automobile.
  • You’ll be able to change the CC mode from auto to automobile or photo voltaic solely.
  • The obtain/add degree is maybe one of the vital helpful options.
    • You’ll be able to set the % you need the facility station to cease charging, which may prolong battery life.
    • You may as well inform the facility plant to cease producing energy at a sure degree.

For the DELTA 2, there are some variations. That has the X-Enhance choice, which permits it to energy units which might be rated larger than it’s able to.

Then you definately even have the choice of sensible technology. The DELTA 2 is suitable with the EcoFlow Gasoline Good Generator, and it will begin charging the DELTA 2 when the battery reaches 20% by default, however the app settings mean you can change this.


A commenter requested about noise from these items. I do not usually preserve mine within the workplace, so it has by no means bothered me this a lot.

Most/all energy stations can have the followers working underneath varied situations.

With the RIVER 2 Professional, when loaded at full pace, you get a couple of minutes with no followers, then it ramps as much as half, then goes to full pace.

You’ll be able to cut back fan noise by decreasing the charging charge.

Equally, when the facility station is in use, it depends upon the facility consumption and the ambient temperature. I ran my desktop PC and a few lights went out for a few hours. Energy consumption remained at 200 W or much less.

After about half-hour, the followers began to work intermittently. They’d keep on for a couple of minute after which flip off. They’re louder than my PC and louder than my quiet music, however I discovered the noise profile wasn’t too unhealthy; They’ve a low to medium tone. If something, I discovered the intermittent nature of the followers spinning extra annoying than the fan noise itself.

On the whole, I’ve discovered the noise from the RIVER 2 Professional and Max to be much less intrusive than the noise from the DELTA 2.

photo voltaic cost

I acquired my unit on the finish of October and it has been consistently cloudy and wet within the north of the UK.

Since I already reviewed the photo voltaic charging of the EcoFlow RIVER 2 MAX, I didn’t absolutely take a look at it with the Professional as they’ve the identical photo voltaic enter.

I beforehand reviewed the 220W EcoFlow Bifacial Photo voltaic Panel and the 400W Large Photo voltaic Panel.

The 220W bifacial photo voltaic panel is ideal for this plant. The double sided panel allowed me to maximise each the photo voltaic panel output and the utmost enter of the RIVER 2. It would not even want wonderful climate, simply clear blue skies and direct daylight.

In use

By way of precise use, there’s not a lot to say in comparison with the RIVER 2 MAX and DELTA 2. In comparison with the smaller RIVER 2 MAX, it has a bigger capability and better peak efficiency.

At 800W complete, there aren’t many high-power units I can consider that take a look at this correctly. You should buy 800W microwaves and kettles, so should you dwell off the grid this will energy some kitchen home equipment.

Like I stated, I’ve largely used it for mid-power units. I arrange my huge desktop PC and it ran fortunately for a few hours. With the brand new report that blackouts could happen this yr, this could comfortably energy my PC and displays for 3 hours.

I additionally used it to arrange a small workstation in my kitchen utilizing GEEKOM Mini IT8 Mini Desktop and Arzopa G1 15.6”, and it really works completely on this situation. Saving me from discovering a cable reel extension.

Worth and various choices

I’ve already been impressed with the EcoFlow RIVER 2 MAX, it is a way more handy measurement than the DELTA 2 and excellent to hold within the trunk of my automobile.

The RIVER 2 Professional is far the identical, simply larger and dearer. It represents good worth for cash in comparison with the MAX. You get 50% extra storage, whereas it solely prices 36% extra, it is solely 27% heavier. The additional socket is good, however extra importantly, the upper 800W output with a 1600W enhance provides you extra flexibility in what you possibly can run and the way a lot.
