EcoFlow Delta 2 Max Solar Generator Power Station Review

[@henrymorgan3982]

Having multiple energy sources can only be realized when one goes down. Great video!

[@jaysonstebbins2539]

Filling a battery is like filling a glass with soda. Fill it up fast to 80% the slow down to top off. Same goes for discharging. The slower you pull from it the more there will be left. That's why recalibration are so important. I do a monthly recalibration on my products. Makes a huge difference!

[@Speed00007]

How do you recalibrate your solar generators? Charge them and discharge them?

[@jaysonstebbins2539]

@Speed00007 for the delta series, I charge to 100% then discharge till the inverter shuts off. Then recharge to 100% as slow as I can or just solar. Then I unplug everything and shut down overnight. You'll know your recalibrating when it takes forever to get from 99% to 100%. I've had it take 2 hours at 400 watts to hit 100% from 99%. It says like 99.49% 2 hours at 400 watts is about 800wh out of calibration lol

[@Speed00007]

@@jaysonstebbins2539 Nice! Thank you for the tips. I'm going to recalibrate mine today.

[@Kievlar]

I don’t have electrical background so I really appreciate that you laymanized solar power terms other KZbinrs have been passively mentioning but never explaining 13:00. I’m a first time viewer of your channel. Thanks.

[@user82938]

Designed to be stacked and they still didn't include a more compact cable with 90 degree connectors. Very odd.

[@minutemanprep]

Agreed.

[@goodcitizen4587]

Yep. A design oversight on all these systems.

[@pifle9471]

Annoyed me from day one.

[@NoZenith]

I keep looking at the Ecoflow Wave 2 with that stubby cable with the 90 degree angled plugs they made for it... I think it would be amazing to have a similar cable with those little 90-degree plugs on it for use with this add-on battery

[@BagelzGaming3]

I used the DC5521 ports for powering my RGB lightstrip stuck around the interior roof of my camper conversion as thats currently my main light source in there, I've also used it for a mini dehumidifier unit from amazon, and also for a Mobile router from TP Link, all came with AC adapters that converted to DC 12v so having the ports right there made it way easier and more efficient!

[@minutemanprep]

Thanks that's a cool way to use them.

[@dermodsmyth7645]

The DC5521 powers my home keyboard, a duracell battery charger and a 12v torch. More efficient to use rather than using the ac/dc adapters that come with each device...

[@CalicoJackxx]

Excellent video, the best that I have seen on the subject. I am very happy with the same set up for my cabin. My wife loves it because it is so simple and safe compared to our original set up of charge controllers, lead acid batteries, inverter and cables . We went with the Delta 2 max because of its light weight of 50 lb compared to the 100lb larger eco flow. That allowed us to easily take it with us to use in our travel trailer on our recent trip to Alaska

[@terrymaxey905]

The small 521 power cord is also used in astronomy for powering telescopes and accessories.

[@dondonaldson1684]

Have you tested powering a 3/4 hp pump? I have a macerating lift pump that takes waste from a sump up to an aeration tank, which then evacuates into a leeching bed. I would like to use the Delta 2 in Max in EPS mode to power the pumps. My concern is the inrush current required for capacitive start motors, not the running consumption.

[@mc7804]

I use the 5521 cable to run a small camping fan that is rechargeable, also for my AA battery charger and a small weather radio.

[@AskIveSolar]

I use those barrel connectors to charge other power stations for example, I see you have the new cellpowa joint, you can go 5521 to 5521 and 100 watt usb c and dual charge it. At least I think the new one can dual charge. I know the old one can. I will adapt them to whatever power station I need. Typically 8mm or 5525 if its a 5521 to 5521. I love those cables. Ive purchased a couple. I have also tried them on other DC electronics such as a small samsung tv that uses a barrel connector. I wish more devices used 5521.

[@HebrewNomadOverlander]

I appreciate the change in battery between the Delta Max and the New Delta Max 2. But other than the lithium iron battery and more cycles, I will stick with my original Delta Max until it dumps. By than if the world is still around, ecoflow will probably have a even better unit. We shall see in 2 years.

[@CherokezPittman]

I completely understand your point about sticking with your original Delta Max until it's no longer functional. It's always good to make the most out of your current equipment. And who knows, in two years, there might be even better options available. Speaking of which, have you checked out the Segway Portable PowerStation Cube Series? It's a versatile powerhouse with a massive capacity, fast recharging, and comprehensive protections. It could be a great addition to your outdoor gear arsenal or home backup power solution. Just something to consider for the future!

[@alzdeane]

I use the DC cable to power a TP-Link 4G router. The supplied power supply had a 9v output, however it's been running on the 12v output from the Delta for months without issues.

[@superlordwar]

I use the 5521 for a 12v fridge. The cigarette light plugs are very fragile to movement so the 5521 is way more reliable.

[@minutemanprep]

Thanks for sharing. Is it a chest fridge?

[@upsitupsi7114]

I personally use the dc barrel a lot for powering wifi routers and ledstrips on the go. They practically work on any standard 12v barrel plug device, which saves you to carry all the power bricks for those things when you want to be mobile.

[@theociba3762]

I just got this as an upgrade from the delta two. Love the detail of every step, connector and switch. Earned a sub from me. Question - is it correct in that these can safely connect to other manufactures panels? Any mfg and or sizing detail you recommend are welcome.

[@hott9053]

Ben! How are you protecting all of your assorted solar generators from a possible EMP?

[@minutemanprep]

Tech Protect faraday bags.

[@Lestat1759]

Why didn't you plug in another 500W of solar to the second XT60 solar input ?! It can be charged by 1000W purely solar.

[@abcamacho6187]

[@mlaetari8402]

Are the add on batteries compatible with the Eco flow delta pro? Since they're now the same chemistry.

[@leguirerj]

The other channels introducing the Delta Max 2 says that red dot indicates that it is a beta unit.

[@DaveSquibbSr]

You can buy adapters for that 5521 plug to fit most any equipment, it's a universal size for DC adaptors.

[@stevang4720]

If you're worried about an emp wont your solar generators be useless if you dont have them in a Faraday cage?

[@stevendavies6209]

You need to look at the true affects of EMP on a Nuclear explosion! It is a mix depending how close you are to the detonation! Most of electrical items will still work, we get EMP's (solar flares) from the Sun daily. Canadian Prepper had an expert on this subject on his channel recently.

But nope...those batteries don't exist on a real man's price scale. They aren't on sale. I was thinking within 6 months I'd pick up the expansion battery for like $700. But everyone says I'll be paying full ridiculous $1600 for it. Which...is...stupid!

[@hatchbacktaco9964]

I use 5521 to power my bougerv 30qt fridge from my bluetti eb70 :) it’s a cable I got on Amazon and I believe it would work with a variety of 12v fridges.

[@LADETROIT]

Can you charge the solar generators with a standard gas generator? Is the power too dirty? And if so do you use surge protectors in between the gas generators and the solar generators? Someone said you can't use modified sine wave inverters to charge the solar generators?

[@minutemanprep]

Yes you can charge from a gas generator. Just make sure the generator has a pure sine wave instead of modified sine wave for clean power.

[@MindOverMetalTV]

Can I us the Delta 2 extra battery to the Delta 2 Max?

[@jimbo92107]

"3000 cycles" doesn't mean the battery stops working after 3000 cycles. It just means that after you completely drain and recharge the unit 3000 times, the battery's capacity may drop below 80 percent of the original capacity. How often do you completely drain the battery? Probably rarely, unless your job is a battery lifecycle tester. Otherwise, it will do its job for decades without fail.

This is literally the only reason I keep looking at Bluetti even though I've seen all the firmware update problems that they have been having. I live in a major city. If I wanted to be secretive about my back up capabilities yet still keep my devices (like my fridge) up and running, I can take Bluetti's expansion batteries to a park, top them off, and bring them back home without interupting my apartment's energy needs. With the ecoflow products, I will always have to disconnect everything for the 3 or 4 hours I'll need to recharge. That is not ideal. I still want ecoflow more than bluetti, but I have to recognize the functionality of the design being superior than ecoflow.

[@superspeeder]

MPPT and outlets on the extra battery? At that point why not just buy two units instead of one + battery? An expansion battery is to expand the capacity of the main unit. Putting the USB output panel on the expansion battery would be cool and wouldn’t add much cost while adding functionality, but more than that you might as well just get another generator.

[@passamaquoddy5590]

So will a xt60 still work in a xt60i port, just at a slower input?

[@minutemanprep]

yes

[@volleyballDave]

Cycles are indeed very important because a NCM battery like in the Delta Max (1600 or 2000) only has 800 cycles after which it can only charge up to 80% of maximum. 800 cycles of fairly constant use is about 2.2 - 3 years of use. Whereas the Delta Max 2 with its LFP battery has 3000+ cycles. 3000+ cycles of fairly constant use is about 8.2 - 10 years of use. Why would anyone consider buying a NCM based power station with that limited lifespan? Limited because of it's number of cycles. Now if you're never going to consider the older NCM batteries and you'll only focus on LFP batteries THEN cycles becomes less important. BUT please don't get everyone else to quit considering cycles because then they'll buying NCM by accident and end up stuck with it.

[@acefire4050]

I don't use gasoline or propane I don't even use electricity from the grid but I would use an inverter to charge up a generator.

[@DanielEarlester]

So it's $1899 and it stores about $0.50 of electricity for argument's sake and it can be charged 3000 times to 80% which is a value of only $1500. Even if it can be charged more times it's difficult to see the value in this if you don't need it for emergencies or outdoor use. For small home it costs more than the amount it can store. When these drop in price then they will be good.

[@teuton6167]
