Ecoflow Delta 2 with expansion battery - Best midsize power station in 2022

[@denvera1g1]

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.

[@TobyCostaRica]

Not only full of tech details, but excellent production quality. Love the cuts, camera movement and angles, audio, graphics. Because I do it myself I know the extra time it takes to execute at this level. Well done!

[@todd.parker]

Thanks so much, really appreciate that

[@ARLGD]

Thanks for your comment! I completely agree with you about the production quality of the video. It really does make a difference when a creator puts in the extra effort. Speaking of quality products, have you heard about the Segway Portable PowerStation Cube Series? It's a versatile powerhouse with a massive capacity of up to 5kWh and a fast recharge time. It's perfect for outdoor enthusiasts like us who value reliability and uninterrupted power supply. You should definitely check it out!

[@cow77cow]

Got my delta 2 two weeks ago and the extra battery just arrived today. Great unit, I use it almost every day.

[@todd.parker]

Great to hear!

[@Jasonoid]

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 Jason! Yeah, this one is a winner for sure. Happy to see the LFP switchover happening so fast.

Note the solar cable they sell is XT60 (yellow) only support 8A, you need XT60i (orange) for 15A which they don’t sell it.

[@todd.parker]

Thanks for the clarification, I was wondering what the difference was in colors, that’s a big difference! I had the XT60i cable from my Delta Max

[@jakeliujakeliu]

No problem, the orange plug XT60i has addition pin in middle.

[@robertlee6781]

The weight of this unit makes it my favorite. I can take this all around my farm to power tools when doing chores. Paired with a Delta 2 Max makes it an amazing supplement to my back up configuration.

[@OFFGRID_Trucker]

Mine is powering my washing machine right now. The extra battery helps outa bit too.. And I bought the Delta first.. I wish I didn't.. but it's still a good backup.

Best comprehensive review on this Delta 2, thanks!

[@todd.parker]

I’m glad you found it helpful!

[@ato5037]

@3:31, you had said that there was 5 AC outlets and 1600w on the Delta 2, but that 1600w was for the original Delta. Just wanted to point that out. All in all, a fine review.

[@larryc1616]

It's 1800w continuous with x-boost to 2200w and surge to 2700w

[@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

[@retnav92]

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.

[@todd.parker]

Quite a collection! I’m sure a LFP Max is in the works, last one to get the upgrade

[@carl799]

Great little unit. Have been using mine, with extra battery, in my camper for the last 16 months. There are two things, though, that make me wish I had not bought it. It is very loud in a small space, and it has insufficient 12-volt output for all those 12 volt items one has in a camper.

[@caravanstuff2827]

Question...the ecoflow delta 2 unit has 1800w and the battery has 1800w is it a combined 3600w or is there some power loss in the system for some reason when their paired??.

[@uaebifvideo5472]

​@@caravanstuff2827Watts is power output , but when adding a battery, that Watt output will not change. What is increased will be your Watt/hour (Wh) ,which is the capacity, meaning, it will run at 1800 watts for longer time !! I hope it's clear.

Looks like you & other KZbinrs raced to be the first to review this product & it appears everyone arrived at the finish line in a tie. So far, your review is the ONLY one I've watched; seems like you covered all the bases in your coherent product review. Indeed, EcoFlow has raised the bar for battery power stations. Excellent, product comparison at the end showing & telling of their pluses & minuses. Yes, I'm a subscriber & "liked" this video. Warm Regards from Reno, Nevada.

[@robertmelton5484]

For someone who has the EB240, I really love the weight savings this offers

[@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?

[@Doge8537]

Great question. I'm curious too

[@Step-n-Wolf]

Just bought one yesterday on Prime sale for $499.

[@meatpopsicle6244]

Same. We have a generator but it isn’t wired into the house and is mainly for hurricanes. For short duration outages my wife can use the Delta 2 to run the fryer and microwave, and power a lamp and charger. I will use the pass through feature to act as a UPS for my media server.

[@Step-n-Wolf]

@@meatpopsicle6244 per my research, the UPS option isn't very good. The reaction time is slow, slower than most electronics can tolerate. You can test that for your particular needs, but you might want a more responsive actual UPS to front end it.

excellent review,you forget about one CON,single one cigerate Dc output limited to 12v/10ah is better and good to have 2 dc output 12v/25ah and 12v/10ah which enable to run high Dc appliances like Dc fridge,Dc fans,DC TV,DC Bulbs etc

[@bernswonger57]

At least oft still has two dc 2521 ports, although rated at 3amps,I plugged in my diesel heater, which pulls 105 watts on start-up. It's never failed, but it does bounce all around from 12 watts to145 watts. Maybe it's designed that way.

[@somcho]

7:30 kW and kWh are *not* the same thing at all. i.e. the extra battery does *not* expand the total maximum power output it only expands the total storage capacity

[@colleenkelley2110]

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?

[@ARLGD]

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!

[@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.

Great job explaining and comparing the units. Thank You

[@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

[@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.

[@K24Z3CU2]

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)

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.

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.

[@wildwestunlimited]

Very professional review!!..... My question is, Is there any solar charging on either of the batteries alone? I know there's charging on the inverter / battery unit, but does either of the batteries have a solar charging port on the battery itself? Thanks!!!

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

Great Video! I have the Delta 2 and am looking to expand it's capacity. However, from information I found online. It says that only the EcoFlow Smart Delta 2 is compatible but you have shown that the EcoFlow Smart Delta 2 MAX can be used together as well but you cant charge it till there is a firmware update? Just want to check if that has been fix via the firmware update already?

[@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)

[@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]

[@danielgjb]

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!

Can you use the max battery on the delta 2 at the same time using the smart generator Or is it one or the other .thanks new subscriber

No because there is only one expansion port. You can, however, plug in the extra battery and recharge it with your generator via the AC cable, it's just a bit less efficient. That's what I do

[@raven793]

@todd.parker @todd.parker So plug the exstra battery into the delta 2 and then recharge the exstra battery using the smart generator..That would give me 3000wh what I'm trying to do is run a 1000wh smart heater incase power goes out while I'm at work 12hrs a night to keep my dog's warm and with just the delta 2 the generator would be running alot cause of it only having 1024wh ..Anyway your Knowledge and content is Awsome..

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

[@LoonyKal]

Amazing video!!! I am from Greece we have plenty of sunny days and i am very close to buy ecoflow delta 2 for "exclusive solar charging", could i use a 550wat solar panel in order to get close to delta 2 max Solar Charging power? also is ecoflow gonna release delta "2" max batteries (2kw) with 3000+ cycles instead of delta max with 800+ cycles?

[@todd.parker]

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

[@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...

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

I tested it and it worked as expected. It’s not a true UPS because there is a brief flash when it switches over. Takes 30ms. Some PCs wood be ok, others would shut down

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

Right now, I’d go for the Delta 2 + battery because it has a LFP battery and is newer. Guessing the Max will be updated very soon

Can’t decide on the Delta 2 extra battery or Delta Max

[@todd.parker]

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.

[@KJPage]

What's the physical height in mm?

[@piconano]

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!

[@piconano]

@@todd.parker Agreed.

[@ImagineGTAVI]

Can the old extra battery from the ecoflow river 1 be used on the new delta 2?

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?

Hi! Is the ecoflow max batterie, LFE chemistry?

@@fckjb284 except the battery % is weird, had it charging to lower & lower percentages. Ended up in the 20% range, advice from Ecoflow wasn’t helpful.

[@detectingrebel]

Good video 👍🏼 Is the Delta Pro the only unit that has EV charging?

[@todd.parker]

I believe so, yes

[@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.

If it’s listed as compatible then it is. When I was testing, it worked but the charging seemed to need refinement because it didn’t slow down for the last 80-90% which is typical. I haven’t re-tested it but can soon

@@LJLion That’s my i understanding and I could be wrong but I heard that the Max needs to be able to pull more amps than the D2 battery can handle so the throughput wouldn’t work. They can be mixed because each has a BMS so it’s possible they could make it work somehow in a firmware update

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. For $700 just no liPo I will wait and hope they fix this efficiency failure on a new model.

[@anthonythomas6977]

Purchased this Black Friday special. Not refurbished. Delta 2 Generator, works well. The smart battery, well um.... Won't charge. By the way who at EcoFlow thought just ONE SINGLE charging method for an extra battery was wise??? Seriously, no solar, no AC, NO OTHER option to charge Smart battery other than connected directly to Delta 2 Generator. Called them twice, Emailed, kept telling me "Update the firmware, should work" Did that, TWICE, have video (posting on my channel today) Still wont charge. Smart Battery came with 30% charge I hooked it up to the Delta 2, feed it just fine, until drained. Now, absolutely NO WAY to recharge the "Smart" battery. I say Ecoflow was not very SMART on this execution. Have 2 other EcoFlow Generator units from March of this year, work just fine. Also own Jackery (meh) RockPals, Nature's Generators, none have a unit with just one SINGLE way to charge.

Very strange. Have you tried charging it via DC (solar or car)? Maybe it’s in an odd state.

[@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%.
