Best reviews on KZbin, I don't buy any electronics until I see a Hobotec review first 😀

[@HOBOTECH]

@@billytanglewood5665 Explain how my review is "slanted". I'm very transparent in my testing and I do identical tests with every power station. I tell it like it is no matter the brand. I don't know how more "objective" a review could be.

[@HOBOTECH]

@@billytanglewood5665 You must be new. I've been doing this amp noise test for nearly the past two years the exact same way for every inverter. All knobs set to max with nothing on the input. I'm not measuring the background HISS but the 60hz BUZZ. This BUZZ is generated by the inverter circuitry and has nothing to do with the amp or the settings. Noisy inverters pass this BUZZ through the amp. Some products produce this BUZZ and others don't. Try watching more of my reviews and see this very objective test over and over again. By the way, it's a Peavey amp not a Roland which makes it clear you're not even paying attention. Try again.

[@HOBOTECH]

@@billytanglewood5665 There's nothing wrong with my test. I've done the A/B in other videos. No need to waste everyone's time. Apparently, the issue is that you're in a different reality. This video is about an ECOFLOW and yours is an ECOTECH. SMDH... Strike two, you're out. When you can't even name products you own the rest becomes BS. Glad your "Ecotech" is working out for you. 😆

This is by far the most informative reivew on the ECOFLOW. You actually saved me from wasting my money - the product is great but the UPS losing power temporarily is a deal breaker... you're the only one who has been fully transparent in your review... THANK YOU

@kkingss4 I’m also curious how this has been working out for you. Can you give us an update?

[@DMAN22yeah]

Well this convinced me to get one. Ive been eyeing the delta max for use in a garage with no power but couldn't stomach the $1800 all at once. I was able to stack your code with an amazon promotion which sealed the deal for me. Update after months of use: I have the delta 2 with the delta max extra battery being used in my garage. Overall I am extremely happy with my purchase. I added a shoulder strap to the delta 2 so I can carry both units at the same time. The delta 2 is capable of powering every load combination I have put on it without hesitation including: 8gal air compressor plus 300w of lights and fans Shop vac, orbital sander, and 300w of lights and fans 6" circular saw plus 300w of lights and fans The only thing I havent tried is my 110v welder which I feel confident it will power. Something I have not seen advertised anywhere is if you have the extra battery connected the unit will charge at up to 1500w. In my testing the unit is also capable of 2200-2300w for up to 30 seconds and 2000w for well over a minute. I am able to fit both the extra battery cable and a shorter ac charging cable in the compartment on the delta max extra battery. The fans are somewhat loud but really arent that bad, if the unit is in the next room charging I only hear it if I really listen for it and in my garage everything I hook up is much louder than the unit itself. I only have two minor complaints, one of which is when ac power is being fed in/out there is a very noticeable high pitched noise from the circuitry inside. It is not a big deal in my application but inside a house it could be rather annoying. The other complaint is that the cable to go between the delta 2 and extra battery is extremely stiff. Its not so bad when its warm out but if its cold at all the cable is horribly stiff to the point that it can be hard to plug into the units. The plugs also stick out really far from the side of the unit. It would be very nice to see a cable with 90 degree connectors on it and a more flexible jacket.

Thorough review - thanks for putting this together. I just picked this up today and it comes with the backup battery. I don't live off grid daily, but when power goes out it should have what I need to run a tv, Mac, and fridge, lights overnight so I can turn off the RV gennie outside.

[@numberwang1256]

Note that the solar/car charge plug on the Delta 2 is not xt60 (2-pin) but xt60i (3-pin). To deal with the 15A car charge problem, they make use of the 3rd pin, even though there are only 2 wires. For the car charger, the 3rd pin is connected to + (flat side of the xt60i), and that is max at 8A input (according to the app). For solar, that 3rd pin is instead connected to the - (rounded side of the xt60i). And that allows for the max. 15A for solar charging. So if you are going to DIY a solar charging cable, make sure you get a xt60i female connector, and make a solder jump to the - terminal inside.

I just received my Delta 2 and ran a few tests to check the UPS function. I attached 3 different computers (not all at once): an old Dell Inspiron laptop without the battery, Desktop computer & Raspberry Pi 4B. I had a lamp attached to see how fast the switching was. There was a visible flicker on the lamp but it was very fast. None of the computers or monitors hiccuped at all. Its like the power wasn’t cut. Also, the oscilloscope does flicker some.

[@zanedzikonski4234]

Thanks

[@ernstbekker8590]

And thank you for the informative review. I actually bought a Delta 2 today and had the same questions, the most relevant being which was which input gets priority when you charge via solar or AC. In South Africa, with our power problems we would actually prefer to have a choice. But I’m hoping they ‘EcoFlow’ have considered it. Will find out this weekend when it’s delivered but I’m hoping it can let you prioritise solar and then AC. Otherwise I’ll have to write to them. Thanks though! Keep up the great work!

[@greensavant2573]

13:28, "So this is not a really good sign", or is it "sine" LOL! Would love to also see "round trip" testing. On the two EcoFlow 1300's I bought on crowd funding, one was 59%, and the other 58%. Pitiful! I bought the 2nd one because mid-campaign they announced that the units could be chained to boost the capacity. However, if you have to put 1278 watts in to only get 741 out, and then "boost" with a 2nd unit, you lose another ~20% of that 741 watts, for a dismal

[@cmorr72]

Great review. Currently saw this unit on Amazon plus 2 100 watt solar panels. thinking about getting this set up for emergency use at home. I cannot beat the price for the performance.

[@rosinstein1501]

Please do an update video on the Delta 2 , the firmware flawlessly fixes the UPS switching! Even overrides a 200 watt AC charge limit to match the draw of a space heater. Very impressed and the new lab feature allow automations that enable you set your charging cycles so for example charge from AC at night when it’s free if you have a solar grid system.

[@donaldmayfield9159]

The fact that Ecoflow did use long life LFP batteries in the Delta 2 makes the more than 10 year usable life a reality.

[@kgal1298]

I was just thinking I would just get another unit than buy their add on battery. Right now I'm looking for a backup for my wifi and fridge if power goes out. Though I do think I'll end up with Ecoflow I'm just trying to determine capacity. I may start with a smaller one to start and add on units later as needed. My main issue is just making sure I can finish my work on a timeley schedule.

[@jasonwomack4064]

I understand the shortcomings, with trying to keep pricing down. But offering battery expansion then limiting it to one battery seems like an intentional shot in the foot. Having the 1800w inverter and expansion to 4-5kw would probably turn more heads.

Not sure what ecoflow was thinking but I am holding out for that perfect generator that is decent cost, has all the bells and whistles and can be used for anything and everything. Am I dreaming perhaps, but I will wait til lit happens

It's a bit disappointing that EcoFlow seems to have cut corners on this. The main reason that stopped me from buying an Ecoflow Delta previously was the fact that they didn't use LiFePO4 batteries, so I was very excited to hear about this. But the low efficiency and the terrible UPS function is a huge letdown. I hope a firmware update takes care of those issues because otherwise this would be a fantastic product.

Agreed the UPS feature is a huge selling point to me and definitely Lifepo4 over there NMC they usually use.

@@fongsa1yuk it's the same delay. You have to keep in mind the load... he's using a 1,200+W heater, which is the worse case scenario. Another thing to keep in mind is the load of your computer... Are you just doing light browsing when the power goes out? Then your power supplies' capacitors should have no trouble bailing you out. But if you're running a heavy load (like an AAA game on your high end video card) then there's a good chance you'll run out of capacitance, and the computer could shut down, or glitch out.

[@bodstrup]

Buying two Delta2’s won’t give you 2 x 1000Wh (or rater 2 x 800Wh) - unless you have an extra unit to join them - have a feeling that the sinus waves have to be in phase before you put them in parallel.. So I see the idea about the cheap battery, And I can easily add a charger on an extension cord if I need more chargers. I hope to pick one up tomorrow for a semi-permanent back-up for our refrigerator- but real role will be to charge at cheap rates between 02:00 and 04:00 at night and run air fryer, toaster, other power hungry appliances at ‘rush hour’ where KWh prices are 2-4 times as much as at 02:00

Can you do a review on the Anker 757 power station, I've watched dozens of other reviews on the 757 and they are all trash, I guess if you are receiving a product free of charge you don't want to say anything negative.

[@worldcomicsreview354]

I've got a smaller Anker (somewhat confusing product range, and some different products seem to have the same number, it's 262-ish wh with a 300w inverter. There's a "plus" version with something like 250wh and a 350w inverter, and it's a bit bluer). It's robustly built and has a nice diffuse light on the back. Only has an 8mm / USB-C bidirectional port for charging, though. The next model up with a 500w inverter has an Anderson port. So I imagine their top model will be decently put together as well. Also Anker's Solarsaga60 panel is absolute crap. I bought a cheapo LVYuan 120w suitcase that charges it better than Anker's own panel. Also the LVYuan outputs from it's (hard-wired, another plus) 8mm and USB-C at the same time, so you can plug both into the Anker at once for combined charging, theoretically up to the full 120 (though apparently the LVYuan USB-C only puts out 40w), but the most I've ever got is 55w, but my panel is very badly-placed and pretty much never gets full sun on all of it at once.

[@TumnusMr]

Would be nice to see a preview of the Anker 767 too. The 757 has been out a while now and there are several favorable reviews on it. The main negative I see on that is the limited solar input of 300W. It would be hard hitting that as the input is limited to 30V and 10A. I know of no single 300W portable panel that would work (the Dokio one is 18V at 15A or thereabouts.) Panels in series would not work as most are 18V+ and there are few 30V 3.3A panels for parallel connections. In fact I think Anker’s own (pricey) 100W panels might be the only ones. This Delta 2 has a similarly disappointing solar input at 500W considering it has an 1800W inverter and up to 3KWh capacity. The Delta 2 efficiency is also low considering Ecoflow’s track record. The Anker 767 uses GaN power switching so it would be interesting to see what efficiency it has.

[@stacky512a]

Hmmm, good information about the spare battery. If it were considerably cheaper than the primary unit, I could see pulling the trigger. But with an amazon coupon along with the hobotech code, i just got the main unit for 679 out the door.

I bought a delta 2 a month ago and was considering using it as a ups. After watching the video, I was curious if the ups function had improved with the latest firmware update. I updated the delta 2 to the latest firmware via the app ( V1.0.1.134) . To test the cutover, I used an old dell laptop (latitude e6530 with nvdia gpu) which has an external removable battery. Laptop uses about 30w-40w while running. I plugged and unplugged the ac power to the delta 2 multiple times (with the laptop battery removed). The laptop continued playing the video I was testing with no drops or flickers. Also ran a cpu stress test using CPu-z and re-ran the ac cutover. Laptop ran with no issues while on the delta 2. Bluetti180 and 200l were the other two I was considering. Also purchased the delta 2 max and expansion battery (qvc had a great sale for the expansion battery at $799 a few week ago). Hobotech just wanted to thank you for your detailed videos. I watched several of them before jumping into purchasing.

[@DownwithDoug]

I currently have the 757 and I'm ready to return it. I'm debating on picking up this model if I can find out a few more details. Right now I use my 757 to power my 12 volt refrigerator. It's in my car running most of the time. A drawback that I have with the 757 is it I have inconsistent sun, the solar charge controller cycles on and off over and over. If it does it enough it actually shuts off at the 12 volt car socket turning my refrigerator off. I reached out to Anker and they said this is normal for the unit. Highly unacceptable for me however they did offer me a full refund.

[@mrhow2712]

Hi Mr hobo. I was wondering if you could answer a question for me? I have the eco flow delta max and I was wondering if I could use a dokio 300w 18v Solare panel to solar charge it? That would be 300w and at 18v That would put me at 16A. And the ecoflow delta can handle up to 10a. So would that fry my power station or is there some built-in protection that will not let it take more than 10 amps? Is it safe to use these panel on my station? If it is safe could I hook up two of them for faster charging?

[@HOBOTECH]

No

[@malifestro3319]

A couple more weeks until the Vigorpool arrives at my doorstep. While that is a very small company compared to the Ecoflow, I suspect it will quickly find the footing it needs. The biggest downside to it over this is a small inverter. But it has a lot of the same Pros and more. It's quieter and if you need more output capacity they said, hey they probably want a bigger battery too. So I really like the idea that it scales.

[@jarellbronson7401]

You can charge the add on battery through the wave 2. Plug the add on battery into the port on the wave 2 and plug it into the wall or use the solar charging port and it will charge through to the extra battery, I know cause I've done it.

[@HOBOTECH]

We all know. This video came out long before the Wave 2...

[@shayne87]

Got mine on Prime day for $411. Mine is purely for emergencies so instead of the Ecoflow extra battery, I got a Siekon 100Ah (1260Wh) battery with a cheap DC to DC step up converter and XT60i (has to be an "i" NOT a XT60) connector to be able to connect it through the solar input at over 400w. That's much higher than my draw would be in a power outage, so that'll keep my power station topped off. I already have a 25A charger for the battery so all together the extra battery cost me less than $280 and is easily expandable for cheap

@@HOBOTECH I guess the next question would be whether one could hook the battery up to the input and the output of the unit at the same time. So the unit is charging the battery, or being charged by the battery depending on the load.

[@qdaddyo1]

I'm confused. I bought an Ecoflow Delta 2 and I wanted to test out how long I can do things like run my fridge to see how long it will run and it says it is outputing 580w and it can run that at 28 minutes. does that sound right? Of course I know nothing about watts/amps ect

[@Curt100]

Yes

[@bbffbee7171]

I would like to know if there is only 150w (below 200w for sure) being drawn from AC output, would any fan of this delta-2 turn on? And, I learn that the AC-charging input can be lowered to 200w,300w... for example, through phone-app. Is it always beneficial to make use of lower-power charging? (say, even 700w, 500w, instead of 1200w.... beneficial to the health of the batteries over time)

[@rogerthornton4068]

Hobotech I just purchased a ecoflow 700 pro for my van. I have a 200 watt renogy solar panel on the roof and was just told by ecoflow that it is not compatible with my solar panel. I could find no warning of this when I shelled out almost $600.00 for product. I now must purchase another solar generator. The one I have cannot even be used as a backup because it is not compatible with my solar panel. People need to know this when buying ecoflow products.

[@GiesbertNijhuis]

With the app, you can slow it down, and make the fans quiet.

[@Johnny_Kanuk]

Is that an Inspiron 6000 or 9400? I had a 9400 way back and loved it. Just happened to see yours and it brought back memories.

[@TobyCostaRica]

I was wondering why EcoFlow marketed it as EPS instead of UPS…now I know 👍🏼

[@keithmorgan266]

How would you compare this to the vigorpool captain 1200?

[@kele1264]

Pretty sure I have the same laptop. 2005 Dell Inspiron. It was a great machine. I've got a MacBook now because the customer service was better. But this puppy is 8 or 9 yrs old. Don't know what I'll get next. Suggestions?

[@marshalljo273]

Thank you for the great review. What about fans noise at e.g. 100 W or 200 W load (e.g. working in small quite office on computer)? How loud is it at small loads? Or when I would be charging it at the camping site with 500W solar - how loud is Delta 2 when charging at 500W? Would it be disturbing for campsites around? Thank you.

[@CallaFab]

I have the Ecoflow Delta 1300 and its a great power source. The only thing that I do not like after owning it for a while is the location of all the ports. USB on front with display. 12volt and 110 on the rear. And charging on the side. All that makes it sort of a PITA to use in small spaces. If I ever get another battery generator, it will be a bluetti or Jackery.

[@stubones]

I bought the River Pro and I was surprised how well the X boost feature works. It powers my gaming pc with a problem.

[@taskelam8937]

Great video! I have a suggestion for a future tests. For solar applications it's crucial to have a good round-trip efficiency in addition to a good inverter and dc circuitry efficiency. Could you also measure the total input energy in kWh needed to charge a solar generator fully? Putting a power meter between the solar array and the MPPT controller input would help in sizing the array. And while you're at it, why not measure the input energy while charging from AC with the Kill a watt you use for inverter output efficiency tests?

[@rasboy342]

Hobotech the best of the best👌

[@roxannajenkins2297]

I have one shot to get a generator for my home/future Van build and I'm so confused. I don't which Eco to get or the Bluetti AC200MAX. Im completely lost with all the different options. Begging for help!

[@YouLookinAtMe-Bro]

I know it's a year later, but what did you decide to get? I'm trying to decide between this and the Bluetti AC180.

[@JustinLO-y7i]

Bought Delta Max, Loving it! ❤

[@vanchick3262]

Honestly longevity is not really a big deal since technology evolves so quickly that today's portable power systems will be well surpassed in performance long before their "life" ends. I am excited to see what's comes out in the years ahead.

[@mitchlogan4796]

It is for doomsday preppers, who are one of the groups of folks buying these. It would just be unfortunate if every manufacturer went to these types of cells, it's nice for different types of consumers to choose what best suits their intended use.

[@thetoolmat8632]

Them doomsday preppers…. They obviously have all the answers, so where is their perfect product? Produce them! - they want the highest standards, and know what they need, no this not dissing on them, seriously, they need to put their money together and produce the finest end all (no pun) power supplies etc… and then make tons of money…as for this set up, I am good with it, hopefully the D2v2 will be better. (And I am serious some DDPrepper needs to start a fund me page with their designs!

[@zanedzikonski4234]

I would agree to an extent. Longevity is perceived as more important on the higher priced units.

[@ChrisHufnagel_Polymath]

Great review on the D2. Thanks for being so thorough. The slow UPS switching is disappointing but it could be fine for applications that don't freak out if power dips for a second. I'll have to think on it a little to see if it is a good fit. Love the Joe Sparks Devil Doll in the back!

[@stevest.martin3940]

I’m trying to think of a reason to buy one of these. I have a 13k backup generator so I think this would just sit in my closet maybe when the price comes down.

[@seekingjoynow1722]

I'm still glad I ordered the Jackery 1000 Pro. It has a Lot of good features and is quiet. My Jackery 500 has served me well so why change solar generators in mid stream.

[@Leoninmiami]

I love your laptop test! love it.

[@dannylau6039]

Hello Sir, Would you know if the DELTA 2 have updated it's firmware so that the EPS switch over keeps the appliance or computer on?

[@Ali-Muscle]

The EcoFlow Delta 2 is Awesome !

[@steveandnaz]

Can you disable Bluetooth on the ACTUAL POWER STATION (not on your phone)

[@bujin5455]

The slow EPS feature is a little too bad, but it's really not that big of a deal. If you really need fast switching, you could always couple it with a real UPS, even a cheap one, and it would be more than enough to fill in the gap.

[@silverbackag9790]

It’s a huge deal for routers, switches, and home servers.

[@ZxAMobile]

@@silverbackag9790And you’re using this for that purpose why? 😂

[@sonshine2030]

which solar panels do you use with it? thank you.

[@stevecraig3004]

Good review, EXCEPT... Ecoflow states in all their manuals that these units(ALL of them) are NOT UPS's. They are EPS's, which means that they will switch over to battery power- with a delay of about 30ms; what I will do is put an actual REAL UPS between the computer and the generator. That way you get the best of both worlds; pass-through power with the generator, lots of backup power for the computer, and instantaneous switching for your computer. Bulletproof. Keep up the good work!

[@islandgirl100able]

What does that mean in terms of what I would have to buy and what it would cost! This is way over my head! Thanks

[@christophercolson4597]

You can actually charge a smart extra battery thru the Ecoflow Wave. I have a Ecoflow Delta Max Smart Extra battery and I charge my battery with my Wave. Charging the smart extra battery with the Wave works pretty much the same way as the add-on battery for the wave. It will generally charge the smart extra battery at about 600 watts with the Wave plugged into AC. Downside is that it does take a bit longer to charge since you are charging at a lower rate then using a power station. I found it take about three hours to charge the Delta Max Smart extra battery from zero to 100%.

[@Bamabrute85]

I don't understand why all power stations don't offer bidirectional USB C ports. Especially considering USB C is capable of 240 watts.

[@BlueSkyLtd.]

Thank-you for this video. How long will the battery inside "live"? If a unit is perfectly handled, minimally used, and stored will it be viable for years and years? Basically, is it a "one time purchase". TY

I was going to buy the delta 2 but now I am not sure. I just contacted them and they said you have to use the phone app to change settings on the power bank. Some of us are trying to prep for a grid down situation where there was an emp or solar flare. So my question is...if you can't use the app to change the settings is the delta 2 still worth it? Can you plug it in and not worry about changing settings or are there absolutely reasons you would for sure need the app? I am not tech savvy and this is hard to figure out what I need.

[@HOBOTECH]

Change your settings to suit your needs then delete the app. App is not necessary to use the product.

[@shellic5166]

@HOBOTECH thank you for answering! I was wondering if once it is set up, whether you really change the settings or need to. But I guess if you really don't need to change the settings, then it is not too bad.

[@rono33]

Professor you rock! Question: does this model allow pass thru charging so I can charge with solar while powering devices at the same time? thx :)

[@HOBOTECH]

I did mention it has that.

[@rono33]

Sorry i missed that :( i’m also really hoping u can test the Pecron E2000 Lifepo4 with 1200 w solar! :)
