Btw, if you think you would want to expand the unit in the future at all and there's not a huge price difference, I would spring for the Delta 2 Max. It's the next one up, of course, but I regretted not getting that one over the Delta 2. The main reason being the Max has some pretty important better features— one of the huge ones being it has two expansion ports instead of just one, which is very limiting. So instead of buying a Max and 2 Max EB's (3 physical units, 6kwh) I ended up having to buy 3 Delta 2's and 3 EB's (6 physical units for the same capacity)... which is a freakin lot of units, and it probably ended up costing me more in the long run. Just something to keep in mind.

Loving the price drops on these recently. Hopefully $300 for a 1000wh come Black Friday.

Yeah same— I would grab this but I already have 3 of these + extra battery. I remember I paid $1,050+tax each for them at the time.Due to the price drops I was finally able to buy 2 of the Delta Pro's + 2 extra batteries... I think I got the main Pro units for like $1,200 thereabout and the EB's for 1,000 or so.One main Pro unit alone used to cost around the same price I paid for 4 of those. I think they once were around $3,800 or something like that? Anyhow, it's now the "old stuff", except it's not really, because functionally, there's not much difference. It's a battery, essentially. The newer units have like 4,000 cycles vs. 3,500 - woooooo. A cycle a day for 10 years before the capacity drops to 80% is more than good enough for me.

I'm more interested in builds for camping/off grid setups. As an alternative to a 100ah battery. I think the 2000wh batteries are closer to that. But you can still build a simple power setup for way less. Just not packaged as nicely.

There's lots of YouTube's for builds.

I did one for a car camping trip to Mongolia with a 100ah AGM battery (before lithiums got cheap). A simple split charge from the alternator to keep it charged. A few 12v outlets and USB plugs for charging and a small converter to charge my laptop/drone etc. I set it up mainly to run a 12v refrigerator. This could all fit in a battery box now with lithiums. My build cost was like $250 I think.

These are much nicer for a clean all in one solution. Still relatively low AH comparatively though IMO.

a 100ah 12v lithium battery has a capacity of 1280Wh.

I would skip this one and go for the Delta 3 Classic that can be had for $349 on TikTok shop. The only advantage of the older Delta 2 is that it has more AC outlets and is expandable, however, it only works with Delta 2 batteries, not the new Delta batteries. The Classic doesn't expand at all, though. If you don't need that, get the Classic.

Curious what the upgrades are to the classic? If you lose the ability to expand and AC ports, not sure I'm seeing the advantage other then the classic being "new"?

one of the reviews mention using this as a UPS but it's not listed as a feature (other models specify that they do)

would it technically work, just not as fast as switching over as the newer ones?

Delta 3 Classic - less ports, not expandable. NO DC outputs. Much quieter (30dB), faster UPS switch oer (<10ms), and latest 3 series app features.

Delta 2 - more ports, expandable, YES has DC outputs (DC5521 and 12V car/cig output). Nosier (~60db), slower EPS switch over (30ms)

Can I hook 2 of these together. I find this cheaper than the extra battery

Holy shit, I just realized it doesn't have a 12v cigarette port. I take back my recommendation. You can't even run a 12v fridge with this thing, unless they can also run on 100w USB-C! How stupid. I see now why people are saying the Delta 3 classic is pointless. Wow.

That's crazy, thanks for pointing it out. 12v to eliminate the AC inverter loss is crucial on these things. Don't get Ecoflow's thinking with this one!
