Battery Power For Audio - EcoFlow Pro

Well I spoke to soon. I plugged in my Synergistic research srx power cord into the Jackery, and the damn fan goes off every few minutes now. It was too good to be true.  Unless there's a fan-less solution,  looks like Stromtank is the only option now .

Update: I plugged In a $200.00 fanless portable power station and it's working beautifully so far.

Wait till you get your EcoFlow Delta 3, it's much quieter. Also the key to have almost noiseless battery is to make sure you are attaching the load which is less than the region where it's loud/fast fan kicks in...for EcoFlow Delta 2 that means below 600W load.

If you can manage that there is nothing like it.

I am using EcoFlow Delta Pro Ultras - they are the newest Lithium batteries which are much lower heat and there is no fan noise. Plus they are near infinitely expandable - I had them running the stereo system while I did all this testing and they are now being permanently put into the power system for the entire house. If you buy them from Costco, the price is outrageously low - with expandability up to 90 kWh to run the entire house on them. 

Goal Zero and others are good too. I am putting in 3 stacks that will have 21600W of battery storage and 7200W output for the house. 

Stromtank not needed … PS Audio not needed.

I have been listening with a 200 dollar portable unit from Amazon with a 10k Synergistic Research cable, with the same enjoyment as a Stromtank. Wierd how this hobby works.

Great advice thank you. I am debating now whether to upgrade to the Ultra.

I would suggest you to wait until you get the Delta 3. After that you can plan to switch your entire system off the grid to the battery just like the @UberK did by calculating how much power would you need for your typical daily session without battery going into it's loud mode.

I am also contemplating on getting the EcoFlow Delta 2 for my system, which is more than sufficient as my entire system just consumes 50 W per hour, so Delta 2 can give me roughly 20 hrs of listening time..if I consider 10% at bottom and 10% at top as reserve limits then even with total 80% battery capacity I can easily run the system for 16 Hrs a day (the demo person asked my friend to use the battery between 10% to 90% limit of the Delta 2 for max life, so I don't know the logic behind this)

There are a lot of weird things in this hobby, the only thing which I have learned is to try to look for the alternatives if any in the Non-audio/Industrial/Research space..it saves money and offers better, measured and reliable performance...especially to things related to power.
