ac regenerator for pc emi/rfi

@ok02 There is no easy answer to your question.

I currently use an ecoflow River Max. My amplifier draws around 35watts which is less than 1/2 amp. The River Max has a 576wh capacity. I never listen for longer than 3 to 4 hours and my battery goes down to no lower than 75% - 80% normally. 

Have a look at the specs of your PC and try and figure out how much it draws. I'm guessing your PC will draw about 200watts.

For my use, I need about 15 times the Wh rating of what I draw. If you use it for longer periods, you want to bump it up. If you plan to use it as a UPS and keep it plugged into the mains most of the time, you can go for a smaller Wh rating.

Battery life is determined by the amount of times it is recharged, so you want to size the battery so that it doesn't drop below 70%-80% in normal use to make it last. If you have to recharge from 0% every day your battery will only last about 18months on average (500 charges). 

So you have to consider how you want to use it; If you use the pc for only a couple of hours at a time and have time to top up the yeti in between use, a 1500X will be fine. If you use it as a UPS - and you need to confirm with Yeti that it can work like a UPS, it's got more than enough power. If you use the PC for 8 hours or so at a time without the yeti plugged into mains (battery only), I think you'd be pushing things. 

Sorry for the long post but there is no yes or no answer to your question.

@pauly so if i want run only battery the pc for 8-10 hours a day what power station u recommend? Yeti 3000x will be enough ? 

Yeti 3000x will be enough ?

Possibly, but if I were in your shoes I would not consider Goal Zero, Eco Flow or any of the camping/solar power one-piece power stations. I would look at something like this  POWER+ Nexus Portable Power Station (3000W) | EGO (egopowerplus.com)

These are power stations that are billed to replace gasoline generators on job sites to run power tools. So they're not really suitable for camping or being charged with solar. However, they have the benefit of running off cordless power tools batteries. So you can power your PC from the power station, and at the same time charge one or two other batteries of a separate charging unit. Once the batteries in the power station start to run down, you can hot swap them for charged batteries and recharge the run down batteries, effectively allowing to run your pc off battery permanently. 

Not sure how the cost stacks up against that of the Yeti. You'll need the power station itself, 3 or 4 batteries and a separate charger.  If you find you underestimated your power requirements, you simply buy one or two more batteries. 

If you buy the wrong Yeti, you're screwed. 

A number manufacturers have these. Just make sure you get one that generates a pure sine wave AV power. A simulated sine generator will possibly destroy your PC - so avoid them.

For the record, I have no experience with the ego power station, so I'm going off what I've read. It does sound promising though and I'll probably be going that route myself in the near future to power my audio system. 

@pauly Thank u so much pauly !! i go with Titan solar generator seems really good unit and pure sine wave
