I wish I had the use for one. That's probably the best price I've seen.

How's this vs the River 3 deal posted a few days ago. Besides the bigger capacity for this one?

This is not really a deal. I got the River 2 pro (x2) for $260 a few months back and it is way better and 50% more capacity. So watch out for that one. Differences:
https://blog.ecoflow.com/us/ecofl...ver-2-pro/

I use the pro for my bbu for sumps, not and issue and another for powering my corded power tools when out and about. The +Xboost on pro makes a difference if this helps.

I am sure the River 3 are marginally better but the pricing way higher, so buy in the middle of the curve. LFP tech is rapidly evolving and there is a glut of supply, so I wouldn't spend more than a few hondo because the 48V systems coming in raw batteries are dropping like stones. So larger battery systems will be dropping dozens of %. On the low end get last years model, IMHO.

Thanks, excellent context for newbies to this tech, like me. Was the River Pro deal here on SDs? Yeah that definitely would have been a better grab. I sprung for this one for primary use as UPS for my home network modem and router, just looking for about a day or so worth of backup run time so for the money I thought this looked pretty decent. Especially vs what new lead acid UPS units cost new, and those batteries are reportedly only good for 3-4 years.

There's a huge discussion amongst PC gamers / audiophiles about home UPS devices using SLA going the way of the dodo soon. If these pre-built consumer friendly batteries keep lowering their transfer times reliably under 15ms and allow pass-through charging; it's going to bust open the overpriced UPS market right now that clings onto horrendously overpriced replacement SLA batteries.

What HP pump are you backing up with the pro? I may have gone overkill with the delta 2 for the same use case.

Its a Zoeller 0.75 HP pump. When grinding its using around 550W. It can handle the inrush which is the big issue, but certainly EcoFlow has done it w/ the R2P.

So these are not good for UPS because what happens is there is a lag between the power interruption and stabilization. I think these are around 40ms and for a true UPS "offline" is 8-12ms. Anything over 25ms and you can have issues w/ electronic components.

They now have LFP 12V that you can use in UPS but really not necessary. I have some very big server ones and local ones. If you say have 1-2 power events per year just stay w/ SLA because they are still cheaper and last 4-5 years. Now if you have 2+ a year then consider the replacement LFP but it is really overkill IMHO.

I am not sure I agree. I just bought an excellent refurb 1000VA pure sinewave Cyberpower for like $130 and it has full warranty, and I can get replacement non OEM SLA still today at 33% the cost of an non OEM LFP. Now that will probably change but you need to think about use case. My SLA last typically 5 ish years. So I can get a UPS half price of a R2 and replacement batteries 1/3 the cost of 12V LFP there is no ROI to your statement today. Worst case the 5 ish years LFP come down and they will get better but there are use cases for float charges and SLA are still at a much better price point. Now if you are seeing monthly power interruptions then I agree there may be a situation where 12V LFP makes sense and even then it is maybe breakeven. Because I am cheap I bring my old LA batteries (car included) to the scrap yard and get some $$$ back to rebate 1/3 the cost. No consumer scrap value for LPF YET. Im sure its coming.

Also and this is one big if. A powerstation is meant to run off the battery not be a UPS and run off the line 99%+ so none of these make statements or publish detailed specs on AVR (automatic voltage regulation) which is a super important component for UPS because if you are 99%+ line voltage stabilization is most important to electronics and even certain inductive loads.

Now I am all for competition and I am sure at some point some vendors (likely Chinese) start running the cost down because at the mid to high end pro/commercial UPS are way expensive, especially if you buy the OEM replacement batteries. As a consumer I would just buy the generic SLA its the same thing as you say for way less cost.

50% more capacity but 50% more expensive so you're still paying the same either way.

The River 3 Plus and Max supposedly can do up to 600w continuously 1200 peak and has a <10 ms ups time supposedly.

Would it work to put a smaller (tiny) capacity traditional UPS in front of it for the response time and then rely on this for capacity?
