EcoFlow RIVER 2 MAX vs RIVER 2 Professional vs DELTA 2 Measurement Comparability – Images

I’m presently gathering energy crops so I had the RIVER 2 MAX, Professional, DELTA 2 and the Jackery Explorer 2000 Professional available after I took these pictures. It offers you an thought of ​​the entire measurement of every unit.

For me, the principle factor is that the RIVER 2 Professional is nicely proportioned, not a lot greater 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 attributable to its measurement and weight once you need one thing somewhat extra portal.

The Jackery is a totally completely different beast. It’s transportable within the sense that I can choose it up. That’s all. It is enormous and cumbersome to move, nevertheless it packs an enormous capability and the 2200W output means it may well 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, nevertheless it was with the Professional.

Having an app for an influence station could appear pointless and also you most likely will not use it a lot, however there are some helpful options.

  • You may 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 may regulate the add velocity. Usually I would depart it at full velocity, however a slower charging velocity will imply the followers spin much less and is a bit higher for the battery.
  • You may change the enter amps of the cardboard; I assume this might be largely useful to your automotive.
  • You may change the CC mode from auto to automotive or photo voltaic solely.
  • The obtain/add degree is maybe some of the helpful options.
    • You may set the % you need the ability station to cease charging, which might prolong battery life.
    • You too can inform the ability 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 gadgets which can be rated increased than it’s able to.

Then you definately even have the choice of good technology. The DELTA 2 is appropriate 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 assist you to change this.


A commenter requested about noise from these models. 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 circumstances.

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

You may scale back fan noise by lowering the charging charge.

Equally, when the ability station is in use, it is determined by the ability 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 few 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.

Basically, 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 always 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 does not even want superb climate, simply clear blue skies and direct daylight.

In use

By way of precise use, there may be 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 gadgets I can consider that take a look at this correctly. You should purchase 800W microwaves and kettles, so for those who stay off the grid this will energy some kitchen home equipment.

Like I mentioned, I’ve largely used it for mid-power gadgets. I arrange my large desktop PC and it ran fortunately for a few hours. With the brand new report that blackouts could happen this 12 months, 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.

The RIVER 2 Professional is way the identical, simply greater and dearer. It represents good worth for cash in comparison with the MAX.
