River 2 Max is on sale around $400 but it is 512Wh vs River 1 Pro 720Wh. Really depends on if you care about extra capacity vs extra features and battery chemistry.
River 2 also has less ports, doesn't have xboost, etc. Its sadly somewhat of a downgrade, outside of lifepo4.

Worth noting some utility companies offer incentives for these electric power banks. They do have some fine print including you have to have purchased it in the last 90 days, but SOCAL Edison was offering $150 back for this
You have to be in a fire prone area now. I cashed in 4 rebates prior 😀

No, Best Buy's is "River", Costco's listings start at "River Pro". Ecoflow's site can help you discern differences but they are not the same SKU/product.

I wouldn't recommend this if you're going to use this at extreme climate. I had it stop working when it reach 0 to negative 5 degrees. I tried to plug a heated blanket in winter.
Another time when it was 135f+. I had it inside a car to power a 12v fridge.

Old tech lithium ion battery. If you using for once a month for outdoor activities are fine. But if you using for solar panels charging everyday , you better stick to new version of Lifepo4,
I thought that NMC, what I am guessing these cells are, is newer tech than lifepo4? I also don't completely agree, our phones have some of the harshest charging patterns and can last for years (they are likely all NMC as well). I do wish these battery banks could be limited in charge state by the user. Usually they are by the manufacturer but you can't do it yourself, max the charge to 80% and set a higher cut off.

Anyone who is expert in this help me understand and decide which one is better to get? Tue delta mini for $600 or the river pro plus the extra battery for $639? The capacity on the latter is more than double the mini for sure but what gives? What is on the mini that would be make it better than the other 2-pack?

I'm thinking of buying one of these for emergencies such as blackouts. What do y'all think?
What do you need to power and for how long? This might work for a light load.

Dealing with gas is a pain in the ass, but you can get a 2k watt inverter gas generator in the same price range:

For gas, the little inverter generators are relatively quiet (though obviously not as quiet as the electric battery storage banks), safe for sensitive electronics, and can run for 6 hours on 50% load. You'll want to run non-ethanol based gas, if possible. Again, it's kind of a pain in the ass, but might be a better option depending on your needs.

What is the rated wattage output of the solar panel? Is the panel included in the Pro package the same as the Max package?

Should I get this or the Bluetti EB70s for $529?
This unit charges in one hour which is much faster than the Bluetti, but Bluetti is lifepo and has higher Watt per outlet. How does the build quality and reliability compare?

Can these act like a UPS? Where it is plugged in all of the time and will switch the load to battery should the power go out?

I have a need for extended run time and the UPSs out there will not accommodate my needs without going to commercial level where I can add additional battery packs.

yes switches within 30 milliseconds to battery according to the technical specs.

River 2 Max absolutely has the xboost feature.. and it's a surprisingly solid-performing unit. Ran my full size french door fridge without issue. Less capacity, sure... but a solid little unit regardless.

They call it "EPS" for emergency supply since it doesn't meet the very rapid switchover UPSs offer... but most devices won't experience interruptions from the 30ms switching they claim. If you do have a problem, you can always keep a UPS in between the unit and your sensitive device

I picked up the Bluetti PS70 too. Nice unit, not a dud out of the box. In looking at specs, I'm not seeing these to be much different (other than Bluetti CS seems iffy). These do act like a UPS (AC pass through) where the Bluetti doesn't. I can see where CPAP users might prefer a UPS type unit. My use case is the same as yours, so I'm not seeing a reason to pay twice as much for the EcoFlow. Maybe someone else can enlighten us more.

I should've clarified: the river 2 max has xboost but it's a measly 1000w, whereas the original is 1800w. I can run basically any device with the original river, absolutely not the case with the river 2 max.

I was really stoked for the river 2 max, just disappointed they dialed it back in almost every regard.
