what i want from the delta 3/pro external batteries, is a dual 500w MPPT charger on each external battery with right angled cables, or rear connectiors so they can be placed close to each other While 2 external batteries can run most of my house overnight, if i want the external bartteries to be charged during the day, grid power is required i'd also love the pro to have 3 battery connectors, with the 3rd one maybe dedicated to the generator if adding a 3rd battery is unreasonable.

Excellent review video, Todd! I loved the comparison section at the end showing other competitors options. This really is the new standard for power stations and other companies need to catch up. I'm glad they finally went with LFP batteries, HUGE plus for safety and longevity!

[@todd.parker]

Thanks Jack!

[@jacksherman7445]

Todd, I listened to your review a second time. Great job! I picked up a refurbished Delta 2 for use as an emergency back up furnace for our home here in the hinterlands of Wisconsin. I had a single circuit manual transfer switch installed, but it appeared easy enough. In my town, all electrical work has to be done by a licensed electrician. Because I had an “extra” Battleborn 12 v 100 ah battery that was supposed to be used in my camper-turns out I didn’t really need it-I use it as a DIY portable battery. I have made numerous “pig tails” that allow me to attach it to various components, charge controller, small DC to AC inverter, Victron charger, etc. Case in point, this DIY unit allows me to add 1200 watts (nominally) to my Delta 2. I have been testing this system out for the last few days and when the furnace fan speed goes up or down, modulating the AC draw, the App reports some odd findings, but it soon settles down. Overall, if I didn’t have the generic 12 v extra battery, I think the Delta 2 extra battery is the way it goes. My set up clearly is not as elegant. However, if necessary, I can separately charge my backup battery and Delta, if need be. Of note, because the Battleborn continuously charges the Delta 2 (it delivers 101 watts with an XT60 connector wired to battery terminal rings), the Battleborn would exhaust it’s charge first, and then the Delta 2 would take over. So, I could charge the backup battery during the 8-10 hours remaining on the Delta 2.

[@jacksherman7445]

I had to return the refurbished unit for defects I cannot recall and EcoFlow sent me a new one. I purchased another new one and have had no incidents. I love the D2 because it can do double duty when I camp-it’s relatively light weight compared to EcoFlow’s larger units was a critical factor for me. Now, despite having a DIY backup battery, the EcoFlow D2 EB is now down to $550. It will provide up to 1800 watts of power delivery, unlike the DIY battery system I have. However, I could use both backups because of their differing inputs. What is your thought based on the current $550 price point for the EB. Thank You.

[@todd.parker]

I feel like the EB is good but if the price is close, you get so much more utility out of the D2. I wish their batteries had USB and DC outputs and solar inputs like Bluetti.

[@jacksherman7445]

@@todd.parker I agree and that is why I have two Delta 2s. However, with the EB, no swapping of D2s is required, like in an overnight grid failure. I’m on the fence. I use one D2 for the electric powering of my furnace via a single circuit EZ transfer switch, and the second for 6 circuits hooked up to a Reliance transfer switch. I would likely use my DIY backup for the furnace powering D2 and the EB for the 6 circuit D2 (has two fridges on it).

Your review of the Delta 2 and expansion batteries is excellent - took 8 pages of hand-written notes! Since I am still in the learning mode on power stations and calculating my specific needs and requirements for a grid down scenario, have you thought about making a video on just how to connect up multiple devices including optimal solar panel setup outside running inside to the power station and ultimately the devices I will define as needed?

[@user-hh6ex9md4w]

Thank you for your comment! I'm glad you found the video review helpful. Considering your interest in connecting multiple devices and setting up an optimal solar panel system, I'd definitely recommend checking out the Segway Portable PowerStation Cube Series. It has a massive capacity, fast recharging, and versatile sockets, making it a great choice for powering your devices during outdoor adventures or even as a backup power source at home. It's worth exploring and considering for your specific needs. Happy camping and stay powered up!

The Delta 2 I ord'd is scheduled to arrive this coming Thursday. Useage will not only be for any possible outages, but it will also be replacing my Jackery 1500 that I use in my square drop trailer when camping. Already own the DeltaMax, two Max Smart batteries, an EF Duel Fuel Generator, and two recently purchased River 2's. The River 2's are not only handy around the house, but will also be used for charging phones and usb fans & lights while camping. Hoping EF comes out with a Delta Max with the LFP technology.

the people at Ecoflow really put a lot of thought and possible use case for this battery, since then, other powerstations became boring in comparison 😂 im still waiting to get a chance to test it here in the philippines , already see it pop up in malls (sadly its just an empty demo shell)

[@alexc9584]

Have to agree, as an owner on the Anker 757 Powerhouse. I got mine for discounted launch price, so slightly less than the Delta 2. The portability and expandability of the Delta 2 vs the Anker makes the Delta 2 the hands down winner. The Anker does have 20% more battery capacity for the price, it's main advantage. I suppose that means for a comparable price your fridge/freezer could run for an extra few hours on the Anker. I'll see if any Black Friday deals pop up for the Delta 2, fingers crossed!

[@todd.parker]

Glad you agree. I do think Anker is improving quickly so maybe the next product or two will help them pull ahead, we’ll have to see. For now, the Delta 2 is the best value at this size and has the best feature set so it’s a slam dunk

[@TobyCostaRica]

I was checking out a friends 757 and was disappointed there’s no app support. Even on my cheapest EcoFlow River 2 I can see the charge level, set a ton of parameters, etc from anywhere. If I were shopping for a 1 kw unit I’d get the Delta 2 based on connectivity. Surprised the 767 has just BT too.

1800 not 1600 watt inverter. Renogy has an interesting 1kw unit that can be paired for 240 split phase for about the same price.

[@UncleJaco]

How do the Delta 2 handle it if the power station is on 50% battery when I plug in the extra battery? Will it run from external battery until it is on 50% too, and then drain both simultaneously? Will it run down both until the power station is on 0% and then external alone? waht happens?

[@rono33]

Outstanding review! Luv the comparisons too. Best review & best in class unit. (BUT, for anyone thinking to add the extra batt for 2kw), I think then the Bluetti AC200 MAX for similar total cost, total higher outputs, much higher solar input, wireless charging pads on top, RV outlet all in a smaller unit since you would have all 2 kW in one box. I know this is a 1KW review. Just speaking for someone who is considering adding the extra battery module to this unit, makes more sense to go to AC200 max. Thoughts?

[@todd.parker]

I think that’s fair. If you need 2kw, the AC200MAX would is a very good choice. It’s much larger and heavier so if you have use cases where you need more portability sometimes then the Delta 2 is better.

[@TheGoodlifeoffgrid]

[@robwinkler4668]

Great review and thanks for the discount code. I don't like the idea of buying the extra battery that doesn't have any usable ports on it for stand alone usage. Could two of the Delta 2 be chained together instead?

[@todd.parker]

Glad the video helped you decide. Unfortunately, 2 Deltas can't chained in the way you're hoping. You could certainly buy a pair of them and swap when one gets low but you might want to get a Delta Max if you need the capacity since it will give you 2kw in one package. It's not LFP but I bet that will change at some point soon-ish. I do wish the batteries were more useful by themselves for sure

[@TheIrishMegaphone]

Thanks Todd for the review. Do you think this could power a front load standard European style washing machine maybe at 30° for a cycle? I saw another guy from the UK on KZbin do it with the deltamax and it used about 15% of the battery - but I’m wondering whether this one could do it with or without the extra battery. What do you think?

[@todd.parker]

I just looked it up and it seems that running a load on cold uses about 500w and on hot 2000w so there’s a big range based on temp. The inverter can output 1,800 continuous and up to 2,300w for about a minute so I think this would work. Worst case, if you run it for a full hour on hot it would need the extra battery but I’m guessing the power use varies a lot over time so it’s not 2000w continuous.

[@TheIrishMegaphone]

@@todd.parker What a detailed answer and fast answer! Thank you so much. Many do reviews on these type of devices but always neglect to mention a washing machine - which is a common appliance.

[@todd.parker]

[@justme507]

Hello Todd, great review, thank you for that. Would have been great to have a better comparison between the Delta2+Delta smart additional 1kw battery and the delta max. The capacity would be the same with the mentioned config, but the question is: using the two delta2 batteries connected, would this also increase the output on this? The delta max can hold around 2,4kw output, the delta2 only 1,8kw… if I connect the additional battery to the delta2, will this increase his output? Which of the two “combinations” would you buy, recommend: Delta2+additional extension battery or delta max? Or wait until a Delta 2 max will be released? Thank you very much.

[@todd.parker]

Good question. If you already have the Delta Max battery, use that but if I was starting from scratch, I'd stick with the D2 battery since it's also LFP. I assume they will upgrade the Max to LFP soon so if you really need more capacity, wait for that. As far as output is concerned, adding extra batteries only increases the runtime, it doesn't make the AC or DC output stronger.

[@georgemountrichas]

Very nice review! I think one thing that was not mentioned is how it performs as a UPS. Did you check that? If so, I would be very interested in hearing your thoughts, please!

[@ZRXBILL]

To be clear, you can’t charge the extra expansion battery by itself?

[@bodstrup]

with the app, can you: - Tell it to charge when it goes below 80% AND time is between say 02:00 and 05:00 (we have variable electricity cost, can be a factor of 3x between night and day)

[@bodstrup]

Answer is NO. You can only set percentages unfortunately. Have to put a ‘clock switch’ in front to limit charging to 00:00 - 05:00 hours - but then - if it goes to zero % at 21:00 - I have no power until midnight. Room for an improvement in the firmware. Had a few AC cut off’s when using XBoost and pulling 2100 W - especially if charging at the same time. Reducing load on my Airfryer - by going from 200 to 190 degrees C lowered consumption to 1900 W - and I was able to complete the cooking (12 minutes). Added a second battery for increased storage

[@under2boots]

Glad to come across your review with a comparison against the Anker 757 which I'm returning in favour of the Delta 2 with the add on battery. Your reference to the reduction in fan speed at lower charging has held me off from cancelling the ecoflow order. It will be charged at less than 200 watts on solar everyday. My only concern is I live in the UK where sun limited in winter. I'd love to know now this is lifep04 will it allow the unit to be connected to the panels on xt60 and switch off at dusk when zero wattage being received, and start charging again (without manual intervention) as soon as daybreak feeds it a couple of watts , 10 watts 30 watts and won't block it like the Anker 757 does. (Xt60 needs disconnecting and the display button to be pressed, to kick it off into charging on solar again ) I need to be assured no manual intervention would be required on the ecoflow. But app access intervention would be fine... any thoughts appreciated...

[@todd.parker]

So you want me to confirm that the solar will start charging in the morning unattended? I think that’s going to work, no problem

[@DRKDNCR]

Fantastic Review! I'd get this if only the AC outlets were in the front as they are with the Delta Pro. I plan on getting the Delta Pro and two extra Batteries side by side on a shelf. Front access to power ports is easier for my intended configuration. I have a question: when charging the Delta 2 and if you have the extra battery attached, does it charge the extra battery from the Delta 2 at the same time or only when the Delta 2 has reached capacity? And how long is the Solar Power Cable connector (if you know)

[@todd.parker]

Thanks! It will charge both batteries at the same time, usually 50/50

thanks for the quick reply Todd. One more question: they spec the solar feed as 60v, 15A...... That's 900w, not 500. Will the unit accept 900 wo damage and use 500? Or do we need to do the math and not exceed 500 for fear of damaging the solar input circuit? Thanks for your help!

[@todd.parker]

@@Hikebike365 good question, that’s…interesting. Maybe they give you that much range for flexibility but cap it at 500w total which is nice because usually there is no way to hit the max unless you have the perfect panel specs. Here, you can use higher voltage panels and it will cap the amps or vice versa. Just don’t exceed the max voltage and you’re good

​@@Hikebike365 It seems as though, 35 volts&15is the sweet spot. Higher voltage, it begins to drop amps in the charge controller.

[@todd.parker]

Unfortunately, no. The batteries don’t have any inputs or outputs and can only be used through the main unit and it’s proprietary cable. Bluetti and Veryeah have batteries that are more useful standalone

[@daddylogan]

Could this be hooked up to a transfer box or a single pole transfer box to power essentionls in the home during a power grid loss? Let's say I wanted to keep the furnace going, a freezer and a fridge and maybe one circuit for a light, modem and computer. (Yes, I plan on getting the extra battery also). The furnace obviously cycles in about 10 minute intervals so it is not running all the time. with that configuration how many hours do you think I could get in an emergency. Where I live, furnace is high priority (North Dakota). Are there videos on how to achive this with a transfer box? Thanks. Very nice review.

I have a question. I have the older 1260wh version. I wanted to use it as a ups leaving it plugged in all the time to home 120 outlet. Because of the pass through power the unit uses your home power when plugged in. Sometimes the unit I had plugged into the ecoflow is not drawing any power, when this happens the ecoflow was over charging the battery and getting warm. The battery percent would drop to 95 and the cooling fans would run with the unit getting very warm. Has this issue been addressed with the newer unit?

[@todd.parker]

I haven't seen that happen in my tests so I think it's resolved. I believe the older Delta didn't have a UPS feature at all so I can see it not working well in this scenario. It's a big upgrade!

You’ll probably want to wire a few panels up to hit the max (11-60V, 15A, 500W max) but it depends on what kind of panels you want. I’m sure a LFP Delta Max is coming very soon so there will be a battery for you

Pls advise which one better to take : Delta 2 with extra battery or Delta Max 2000?

[@winstonsmiths2449]

I have been TRYING to talk myself out of buying the D2 and the DMax Extra battery. The opposite has happened: i find vids like this that confirm that this unit is the best in class. My fear now is that EF will introduce s newer version or offer an even better price right after I buy the units. I am suffering from paralysis by analysis? I want the DMax battery even with NCM chem. I figure it will get to 80% capacity faster, but since it has twice the capacity, its life time output will surpass that of a D2 extra battery. My concern prior to ordering is that the D2 is 120v output, the DMAX spec states the battery is 110v. Not sure what affect that will have, I AssU_Me that would lower the main unit (D2) to 110v.

[@todd.parker]

I think Ecoflow is moving to LFP with good/better/best lineups for small (River) and large (Delta) so the D2 will remain the same for a while. I expect a LFP Delta Max soon since it’s now the only NCM unit in the Delta lineup (not sure what is happening with the Delta mini)

If you want to buy now, I'd go Delta 2 because of the LFP battery. If you can wait a few months, I'm sure there will be a Delta 2 Max coming out that will be LFP since it's the last one in the lineup using NCM.

Loving my delta 2. Only thing I’ve been hearing from other utubers is ups power backup of 30 milliseconds is too slow and may damage some sensitive equipment.?

[@todd.parker]

I doubt it would damage anything but it just means that if you were running a desktop computer it might cause it to shut off and restart rather than staying on because there is too much of a gap. Even that depends on your computer, some can keep running to cover the 30ms. For other things like your internet router, worst case is it restarts when it switches over

60V 500W max solar charging was a deal breaker for me. Bigger battery and inverter helped to swallow the price pill. I went with a Bluetti AC200P. its 150V 700W max solar input, closed the deal. Hooking it up to 4x200W 12V Renogy panels in series. The extra Watts comes in handy with partial shading and cloudy days, and wasted in full Sun.

[@todd.parker]

Yeah, for a unit this size, it's a reasonable spec but with the extra battery, it starts to be closer to the AC200P size category and that has a much better solar charger. Sort of depends on if you want a portable, modular system or a more powerful but harder to move unit. I like the 200P but it's heavy!

Why at 100 percent charge on both batteries, when using my air fryer for 4 minutes 5 times I'm down from 100 percent charge on both batteries to 50 percent on the main battery and 57 percent on the extra battery. Im surprised and disappointed this unit uses so much power so quickly. This wouldnt keep me going in a power outage for more that 40 minutes total. That's connecting just one appliance that's 1500 W. Am I doing something wrong?

That doesn’t seem right. How much power is it pulling?

[@MM-ce2ns]

Is the Delta 2 extra battery compatible with Delta Max????😅

[@todd.parker]

I don’t think so. They can connect but it may void your warranty

[@shellic5166]

Delta 2 was my number one option because of the expansion options. But in reality the expansion is useless if you are limited to the 500W charging. They may say 500W but you can't get that. The most you can get is two 220W panels. So with only 440W, if you have two expansion batteries, is completely unrealistic to rely solely on solar to charge. It would take way too long. I am looking at these for a grid down situation and camping. The only way the expansion batteries work, is if you can charge them fast at home. Relying solely on solar won't work for keeping them fully charge each day. That is hugely disappointing.

[@todd.parker]

Yeah, I can see that. A lot of companies are offering expansion batteries like that that can only be charged through the main unit and the solar input is only fast enough for the main unit. That said, you should be able to recharge a D2 + 1kw extra battery in a solid day of sun. A 2kw pack or second battery, no way.

I wanted to like this but it’s only 76% of the battery capacity that it’s listed at due to a failure of efficiency. It’s literally the worst one they have made in terms of efficiency and is way below industry standard. The delta MINi actually has more capacity because it’s 91% efficient. Crazy.

[@dino1604]

Could someone explain, why it is "impressive" to get 830 Wh out of an 1024 Wh battery capacity? To me it would seem like they are lying about the real content of the battery. Almost a difference of 20% to what they claim.

[@todd.parker]

They aren't lying - the actual battery cells are 1,024 but to use them you need to convert that the 48v DC cell pack voltage to 12v or 5V (USB) or 120v AC - all of those have conversion losses (heat) so this test tells us how efficient it is at this job. 20% losses is typical so that's our baseline for judging these. When you put gas into a car, the gas has a specific amount of energy stored but each car will give you different miles per gallon (MPG) because some of that energy is converted into waste heat. Same idea.

[@dino1604]

@@todd.parker Wouldn't it be fair then, on a consumer perspective to state the real Watt hours, or store more cells so you get a practical 1 kWh out of it. A normal first time buyer would expect, for instance an appliance that constantly drains an output of 100W to be powered for 10 hours, not 8 hours. Feels like a sale lie to me, like selling a can of beans and just stating the total weight including the can and water, not telling the nett bean weight when drained.. Thank you for replying to my comment btw.

[@todd.parker]

@@dino1604 I totally agree that the way these are marketed across all companies leads to disappointment because you lose around 20% off the top of you run the battery down in 5 hours. If you’re running smaller loads for longer, losses actually increase because there is idle power draw. It’s a bit nuanced to explain to a consumer but it makes it confusing overall.

[@dino1604]

@@todd.parker To touch on the smaller loads for longer aspect: I saw a video testing the EPS on the new delta 2, and I saw that it was pulling in 50w while outputting 40 W. The 10W difference for the invertor/unit itself, I found very large. It would be kind of neglectable if you would use powertools and run the whole battery in like 2 hours or so (just losing 20 watts of the total of the potential 1024 to just the unit itself) but I find it a shame if you would have a low powerdraw situation of 50 watts with the unit using 10 watts (at 80watts even more because the fans kick in), and thus being a relative 20% of your consumption and thereby losing your potential of drawing 50watts for 20 hours and now the realistic picture being 50+10 for 16ish hours. Comes close to your tested 83%.

I did talk myself out of buying the D2! The efficiency of this unit is only 80%! I would expect at least 85% for these units.

And the extra batteries are useless without the main D2 unit. They should be usable no matter which main unit is being used. And coercing buyers to buy their solar panel cables is downright Olight-ish. They only come if you buy their panels. You can make your own if you buy the connectors and a soldering iron. I am going to wait a few weeks or months to see what else is released by whichever mfg. I have 7,200w usable solar storage capacity now, so I can work with what I got and do not "need" the D2.
