I recently purchased an Ecoflow Delta Three Max Portable Power Station for power outages and emergencies. About a week ago, I became curious how my system would sound if I powered my system from the power station. Since I have everything powered downstream from my SnubStation Zero, I simply unplugged the power from the wall and plugged in from the power station. I had no idea how it would sound but I wanted to find out. I listened for several days with a large variety of music. I’ve been trying since to conceptualize what I heard.  

The changes I hear seemed to be centered around density and greater detail, likely due to the elimination of power related noise. The one thing that was completely unexpected was the increase in the weight of the bass. I wasn’t even aware my amp could have such powerful bass. Detail, that was once masked or blurred by noise, is easily heard in a sound space with solid and harmonically rich voices and instruments. I can now hear/feel the full weight of an orchestra. The highs are sweet, extended and without any discernable edge. In my system, this greater density and detail results in a richer harmonic balance that can be quite subtle.

I took the next step and plugged the power station into the wall. I wanted to see if what I was hearing would still be evident with the power station plugged in, i.e. being able to have these changes without concern for draining the battery. It also passed that hearing test. At this point I was considering incorporating this power station into my system. However, the power station is big and weighs around 45 pounds. It would be awkward to incorporate.
I then decided to order a smaller version that would be more manageable, specifically the EcoFlow RIVER 2 Max. It is smaller and only weighs 13 pounds. After I received it and charged the battery, I also listened to it with the power station unplugged and plugged into the wall. The sound remained consistent, plugged or unplugged in the wall.
The only potential drawback is the smaller unit has a fan that comes on often. I installed the power station in a cabinet with only the back open to the air. I cannot hear the fan in the cabinet.

I have incorporated this power station into my system.

On a side note, the power station app displays the amount of power used real time. Between my Holo Audio May and my SE84UFO amp, my power draw only required between 107 to 114 watts.

Hi guys,
MM, I followed your thread with interest. It actually got me to research those Ecolab generators. I have not pulled the trigger yet. Plan on using it for emergency power and maybe audio systems power. What unit did you get? Sorry if you already mentioned it in your thread.
ArtMan it seems you found out what an unwavering power source can do to bass reproduction. It seems Decware amps(maybe fleawatt SE tube amps in general) really shine with local on the spot power without long running wires. I attribute my cap banks do much of the same. Going to check out your units.
Thanks
