Switching to battery power


Hi

Has anybody switched their audio system either wholly or partially to battery power? I've read that some folks have had good results using Goal Zero power stations for doing this, but I'm sure a couple of quality deep cycle and good full wave inverter would work no?

Please share if you have tried it and what your finding were.

Thanks

I bought this  EcoFlow RIVER Portable Power Station . I did because it was cheap, it had very good reviews, it does what I am looking for, and this particular model can be be expanded/enlarged.

A few days before it arrived I had amp issues and had to switch to my backup amp which am not as familiar with. Also, right before it arrived, part of my acoustic treatment fell off my ceiling - no treatment for the first reflection point of left speaker. The battery gods were not helping it seems?

My setup for the amp is a Furmam pro, feeding a 1mtr Wireworld silver electra into a balanced transformer and then a 3mtr  Wireworld silver electra to feed the amp. That I changed to the ecoflow and the 3mtr silver eletra. 

Right off the bat I felt there was a a little more detail I could not hear before or could barely hear before. I was very impressed given the lack of diffusion in my ceiling that I felt added detail. What was even more impressive is that I normally listen at night as my sound is not that good the day, but I this was during the day. It had turned day into night. Very impressive given my pre amp and streamer was still on mains power. 

The sound was not constrained in any way, in fact if anything it sounded more dynamic than ever. 

Other nice things about this battery is that it has a couple of 5v and 12v DC output too, so you can run equipment that rely on wallwarts.
It's also wifi enabled, and you can keep an eye battery levels etc. from your iPad. 

The not so good things. The battery went down waaaaay faster than I thought when using 120v AC. The 5v and 12v DC output would last days, but the AC out seems to be very inefficient.  Note, my spud amp draws only 35 watts and has an output of a whopping 2wpc into 8ohms.

It also has a fan which would run when the AC was used. It's very quiet, but you have to orientate the battery so the fan exhaust point away from you (and not at a hard reflective surface)

I've ordered the EcoFlow RIVER Extra Battery which I believe will give me around 5 hours of listening. 

I highly highly highly recommend switching to battery, but I would suggest going for the larger models for components that consume 120v AC. 
pauly, that sounds great. I have my DAC, renderer, Quad 2905 ESL's, phono amp and turntable that I would like to power by a battery generator and the ECO is affordable.
I'm not sure how I would manage to keep my ESL's plugged in if connected to the battery.
Take 2 on the battery charge. 
For some reason my battery is not getting drained today. I suspect I had not had it fully charged before. I had on charge over night and most of the morning. It’s hanging in there like a champ tonight. 
I gotta find a way to use a battery generator but keep my Quad ESL's plugged into power 24/7. Any ideas?
