Thanks for the review. It just made me realize how important it is to have a power station like the Delta Max.

I got the Delta Max and all I can say is that it is one hell of a powerful power station.

I really like all your thorough reviews of solar generators and solar panels. Thanks 👍😁

Your honesty is your strongest suit Jason, thank you, more power to you.

EXCELLENT JOB Jasonoid.👍🙂

Video is perfect. I've got everything i need to know in 20 minutes. Thank you

Awesome video, great job on the way you broke down the cost per life cycle.

I got mine yesterday so far I only tested it with my portable cooler. Enjoyed for one day looking to do more testing

another excellent review. it helps with purchase decisions. thank you.

Great presentation. You are so clear on the options. I would feel more comfortable with the Pro. I want to reduce my dependency on the grid as much as possible . I would find more daily uses for a power station not just for grid down. When comparing the the Pro. I would get a AC 200 for the cost per unit. I learned a from this video. Peace

The Delta Max is something that I can really use for my outdoor life.

Very good review, ECOFLOW has one of the best power stations out there. I did a long term review of my ECOFLOW River Pro and that thing lets me work from home off grid all day.

Thanks Jason🌷

I currently am using one to power up and charge my DJI drones and it is exceptional.

I wish I could afford a Delta Pro. This is definitely a premium product, but my use-case is long term grid down and/or off-grid, so battery life is extremely important. Nice review on this one.

Thank you for taking the time to make these videos! Any word on if you will test the Goal Zero Yeti series? I had the 1500 for years until it was stolen from a UHaul during a move... It was sad, understanding that it went with me all over the country w/ virtually unlimited phone and speaker charging. Now, I'm ready for an upgrade! Although it is certainly no generator like the Eco Flow, it took care of basic charging needs while on the road. I'd love to hear how the Goal Zero series compares. I need a mobile setup now as well as a home backup system... Both brands seem to be relatively popular selling through their site or REI; delving into all the other brands would be overwhelming without your help! Thanks again!

sure this is a little on the expensive side, but otherwise a really nice unit. the fast charging is excellent. and efficiency of the ac inverter is great too. the 13+ hrs at max discharge from DC is a really long time! it could run that 12v fridge for many days. as far as not having bi-directional charging on this huge capacity unit, i dont think its needed. i think its only needed on smaller units. thank you again for your in depth reviews!

Great Honest review. I personally would prefer one with LiFePo battery if I am spending over $500.00 for a power bank.

One of the best back up power for your home. #Ecoflow #Backup #DeltaMax

This Delta Max clearly beats all the other power station in its category.

I would go with the Delta Pro

Excellent review. You confirm my experience. I have about 6 wks of actual usage on my Delta Max with two Smart Batteries powering the AC galley and DC circuits in our 28’ Airstream thru an inside shore power inlet and automatic transfer switch. I charge by solar when boondocking and AC when we take a campsite with power. My only disappointment is that I cannot utilize the 400W inverter in my truck to charge, as the Delta Max requires pure sine wave input.

Jason, the reason it was not charging at the higher wattage is because the Delta max checks for voltage sag on the AC input source. If it detects possible lower amp capability coming from the breaker box, it will reduce max charging input to prevent overheating wires in wall, and popping a breaker. I tested this by trying outlet in kitchen, and obtained 1750 watts.

Love your videos. I think it's great that you do the sound measurement and it's a good rough estimate. However, if you want to improve consistency, I would try to control the distance of the decibel meter, take a measurement with your hands off, and maybe measure the noise floor in your room when nothing is running. Keep up the good work!

Hi Jason, is there an update regarding the parasitic drain test? BR Patrick

Just ordered the delta max 2000. It was a toss up between this and the ac200max. Life cycle and no bidirectional usbc was the con for me. But the quick charge and not needing all the adapters and simplicity was kinda the winner for me since my wife will be using too. I have a smaller inverter generator and 1000 watt solar setup for my offgrid shed il be going between lol .What are your thoughts between the 2? Thanks for the video!

Can you recommend some solar panels that are low amps since it can be an issue

Kool!!!

Great Video on the Delta Max.......Question though.......We are using ours only for power outages so it will be stored away for longer periods of time........can I store the Delta Max at 90-100% power or should I store it at a lower percentage.......I heard you are supposed to store for long periods of time at around 30-40%...which would be a bummer if the power goes out all of a sudden and we are not charged to the full capacity when it is most needed. Your thoughts?

Does the delta max have the 30 amp output like the Bluetooth ac200max? 200 max was your recommendation for us to run with a transfer panel for a little help on electricity. Only reason we bring this up is we saw the delta max on sell for about $1400. We thought this might be as good as the ac200max. Thanks for your videos and help

Hello jason, another great video. I have an Eco flow Delta the original one the 1200 watt plus the River Pro and was thinking about upgrading to the eco-flow max. I only really use it in emergency situations which would probably be maybe once every 3 months so that's why I went with the original Delta. And I will be upgrading to the max. You're really cannot beat the eco-flow max when it comes to that gigantic converter 2400 watt inverter when it's only got the 2000 watt battery. Very few power stations are like that. Question for you, if I get one of these either the max or another Delta or even the Delta Mini, how often in your opinion should you top it off to 100%? In other words if it's sitting in the corner for 6 weeks and has been turned off the whole time would you recommend topping it off for 20 minutes or so every 6 weeks? Maybe every 3 months or 6 months? Any information would be greatly appreciated love your videos keep up the amazing work. Your fellow KZfaq friend, Jason

Another great review Jasonoid!!! Thank you again for my Amazon gift certificate I won on your recent giveaway and just to let you know thus far we do like the $399 1000w EcoWorthy generator I asked you to look at for me 😊

Good video, thanks. You claim the DC5521 ports output 12+V, 10A whereas EcoFlow's specs claim only 12.6V, 3A. Which is correct?

Since you are using a 2-wire measurement device for the DC capacity test, you should take into account the voltage drop over the wires. This way the DC output efficiency would be around 88%.

Im not big on the numbers or names/models but is this the ecoflow delta max 1600 and if it is what do you think about charging a lawn mower that has those faucfait batteries about once a week am i going to notice a difference?Thankyou!

Thinking of Deta 2 plus extra battery compared to the Max due to the battery type and price

What level of power draw did you draw at for the AC drain test? Like 1000w or 500w or 1500w? Continuously?

Hello I recently received the Delta Max. It came with 30%. Once I charge it to 100% for the first time should I drain it to 0% for calibration purposes or never let it go under 20%?

A little hesitant about getting this one as seen reviews People with it had problems with error codes and display panel and some were saying after 4 to 6 months it was not useable for reasons they did not look into. They claimed it work for a short time then was having issues ..NOT ALL BUT SOME UNITS ..DO I WANT TO TAKE THAT CHANCE?!

Can you wire directly to your hones power panel?

This or Ac200P? Which is better? In 1- battery cycle 2- battery chemistry?

I just picked up the River Pro on sale at Costco for $429. Today I did an AC draw down test using a computer and an outlet watt meter. Unfortunately I only got 485 watts out of it. Do these batteries need to go through a few cycles before reaching max output or do I need to use a more uniform source? Anyway I charged the battery up again, Took 1 hr 37 minutes but also 860 watts to get to a full charge. I'm running a fan which is drawing around 70 watts and will see what I get this time.

Would 175w Renogy Solar Panels work with this or are the amps too much? Thanks

What other brands have you tested?

Question re Life cycles: are any life cycles used if used only as a backup, constantly connected to the grid power so that there is no effective discharge from the battery to the connected appliances ?

Hi I am finding I am not interested in ION lithium batteries. Even Bluetti has some and I was assuming they had all LiePO4 ,,,

I thought it was Lithium NMC, not Lithium NCM. Is there a difference?

You should make a Parasitic Drain Chart of your Solar Power Stations

UPS or not? Your grading sheet shows that this unit has a UPS up to 2200W but you don't mention in your review. I want to have an uninterrupted Power for a sump pump so it is critical that I have a UPS. Does this unit have UPS or not and if so to what amount?

What's the difference between the 1600 and the 2000? is it worth it?

There are several serious flaws in EcoFlow app currently ... 1. it require cloud login to work ... e.g. If there is power outage (or EcoFlow servers have problem) then you may be stuck with incompatible configuration of power station. Depending on configuration it may significantly restrict usage or render it completely useless. There is no way to do factory reset without app on phone. 2. direct connection is not secured ... There is possibility to connect to power station directly (e.g. without cloud / internet). It is working only if you are already logged-in to app (problem 1). Connection between app and power station is using open WiFi with no protection at any level. Anyone with-in range of internal WiFi module can modify settings. This may disrupt operation and in worst case scenario cause fire ... I think it is really dumb approach to configure even basic stuff via app. There should be several additional buttons and menu on device itself with all settings available directly on device ... On top of ^^^ there are additional problems on device itself. Like it is not possible to disable WiFi connectivity and sometimes you can see someone else power station in your app. Power station is not working on WiFi with long password (24 characters), on WiFi with space (blank) in password, etc ... I hope that at least some problems will be fixed with that OTA firmware update ...

the air coming out being cool isn't necessarily a good thing. If the fans and heatsinks are doing their job, you should expect the air to feel hot from an exhaust. The only temperature that is of interest is from the internals.

has anybody charged by Car Battery alternator? not the cig or power 12 v 8 amp- if anybody has any problems using car battery or extra added batteries to car?

Can this be charged by my car during driving?

very useful video for Ukrainians (for me in particular)

Darn why does this unit have such small DC output? Only one 12 volt 10 amp plug. Given the size of the unit you would think it would have dual 12 volt DC outputs or higher amperage. Competitors products that are cheaper have higher amperage. I guess it's not for RV van DC optimization loading.

It seems the cost of these items have dropped exponentially over the last few years. My intentions are to take a car alternator and hook a DC power motor directly to it and run it through a inverter to charge my power station. I guess my question is, or my intentions are, to run the 12 V motor that is powering my alternator to charge my power station. Also having the solar panels hooked up at the same time. I don’t intend on running the alternator off the cars engine. Seems like a way to eliminate my electric company. Maybe having up to three power stations would be proficient.

There is no need whatsoever to have bi-directional usbC on larger power stations. You would be charging it forever!!

I just cant see spending that much coin on anything but lifepo4. Not just cycles and safety, but calender aging of the cells. NMC cells age much quicker than LFP , something like 3x faster.

So you saying it should plug in my 3600watt 240 volts 50 amp kitchen oven stove or my 4800 watt 220 volt 30 amp water heater. Yes I know I can run my kitchen refrigerator for about 1 hour my kitchen refrigerator is a 2000 watt antique refrigerator occur in my microwave for about an hour-and-a-half if I'm using it slightly longer if I'm using air fryers. It can run my lights in the house my TV's computers charge my phone's make game systems all night long but nothing major that needs to run without run it out of very quickly the batteries something's would last a little bit longer I can use it for running all the lights in my house all my none a Central things in my house that is not important. It will run one of my split air conditioner heater for about 3 hours of course that would be the only one that can run that's the only one that's 115 votes 850 watts all my other split air conditioner heaters are 213 to 230 volts. Don't get me wrong I I do want couple of those generates and it's batteries as well as the three or four Delta pro and it's batteries But they might be used for something else then running my house since the power really kind of come short even with the power going out those who died just a few hours after they start running to backup power so I'd have a different use for those generators.

I will never buy anything again from ecoflow. During black friday I made the mistake of trusting what I read on their website. The ad read "ecoflow deltamax 2000 + 220w solar panel, black friday 2022 $2199." I clicked on buy and purchased it. A few days later I received the unit without a solar panel. I immediately called their 1800 number and informed them I had not received the solar panel. The man on the phone told me I had not ordered the solar panel. Wait...what? The ad said " deltamax 2000 +220w solar panel black friday 2022, $2199." Be very very careful buying anything from this company.

I sent you a message on the website Jason. I could use your help.
