EcoFlow Delta 2 Max Solar Generator Power Station Review 

We have used the ru-vid.comUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y for probably 30 hours with our camper and it’s been great! The noise level is really only noticeable when running the AC and other appliances like the microwave, hair dryer, or coffee pot. It’s not huge like other ones and it has wheels so even at 90lbs, I can move it!

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

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!

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

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!

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.

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.

I have a lot of photography equipment that uses those barrel plugs, so that's a nice bonus.

Good review!!! Keep up the good work!!

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.

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.

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

Awesome video! I had the delta max 2k and I wish this was out when I bought it !

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.

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.

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

I was looking forward to seeing this. Thank

Great video, you answered all of my questions 😉

One really, really good upgrade option they could put on these is Anderson powerpole connectors. Or make adapters available to do this plug n play.

I use the 5521 for lighting under the cabinets, security and surveillance cameras , to include by bi-pap machines. LED lights instead of usb lights and so on.

I have a 120mm PC fan connected to the DC5521 port, which cools PowerStream.

I use the DC 5.5mm x 2.1mm connector to run my analog TV sometimes.

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

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

I use the 12VDC 5521 to run both my security DVR controller/recorder and cameras. I can also use the 5521 on some of my Baofeng radio chargers, tho I am shifting to USB C for comms.

Great video.

Great video

Being new to this and I just bought one of these, you’re saying that each of the solar panel inputs can handle a maximum of 60 V? So I could technically do two series of 2 20 V panels totaling 40 in each port?

Cable mgmt is a nightmare with everything. They need to make a cable option that connects the two that tightly snug the sides of both units and has elbow connectors.

Great content

I found a big sale on ecoflow delta max 2000, should I as an absolute beginner in an apartment choose that one instead? Mainly for cpap security and food preparation, as well as charging wheelchair overnight and also electric blanket. Of course also keeping smartphone alive

Would been great to have ANOTHER Solar Panel Set (600watt, which equals the almost 500watts) to the Echo, a TOTAL of over 900watt Solar input.

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

Which panels would you recommend? I have 2 - 110 Echoflo panels but would like something with much higher output.

Thank you

😂😂 as soon as i see sponsored videos on these power banks i SKIIIIIIPPP lol

Obv I’m late in commenting, but an update on the xt65 to mc4 cable. I just ordered the Ecoflow 220W panel on eBay for $242 (refurbished with 1 yr warranty) looks brand new AND it comes with the xt65-mc4 cable!

DC 5521 used to charge Bose Soundlink portable speaker

ECOFLOW DELTA 2 Max 2400Wh suggest solar charge input 500 watts. My solar panels produce 60 VDC/10 amps to the breaker box. Can I safely input from the solar breaker box two XT60 cables into the two solar charge in-ports? Enjoyed your video, appreciate your help.

Charging a battery is like humans filling a stadium. The fuller the stadium, the harder it is to get to your seat.

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

Will these units survive an EMP or do you need to protect them in a faraday cage until you need them after the EMP strikes?

When you mentioned app application if the internet is off can it still controlled by Bluetooth as we know it ??

I wonder if a custom cable could be fashioned to pump 15A or more at 12.5V into each of the solar charge controllers? My application would be to recharge the device from a rather large house bank on a boat.

5521 Port is great for my Reolink Security Camera

Very good story.

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?

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.

Would the EcoFlow Delta 2max with 3 400watt Panels work for my good truck that has been running on a 7200watt generator?

Any thoughts on this vs BLUETTI AC200MAX? Thanks for the great reviews!

You mentioned an EMP - wouldn't that fry the electronics in those battery packs? I have thought about this a lot and actually wondered what would happen.

ecoflow should make some right angle plugs for the aux batteries !

Can you use xt60 instead of xt60i? Just bought one on Amazon the other day with 2x220w panels and purchased 2 xt60 cables instead of the xt60i cables

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

Doesnt look like it has a 30amp plug. How would you connect it to a transfer switch?

Other You Tube reviewers have mentioned the red tool symbol was for Beta users or reviewers who received these units before the official EF launch date.

You mentioned warranty, repairs and shipping, that they've been great on the occasions when you've needes to. How many times have you needed to?? Even inside 2 years of ownership at the most. That's very concerning. I want something that just works and has been properly field-tested.

Wondering if using an XT60 Y Splitter to feed both DC inputs from one 800W solar feed would work. 🤔

Is the ecoflow delta 2 max extra battery (LFP) compatibile with the original delta max (Li-Ion) ? Because delta 2 (LFP) is compatible with the delta max extra battery (Li-Ion). Also is the delta 2 extra battery (LFP) compatibile with the original delta max (Li-Ion)? Thx

Is this 60volts pv input on each? Terminal input?

I talked to customer service and was told that you can not charge the Delta 2 Max with Extra Battery attached using their Smart Generator. Now I am confused.

I just checked my EF Delta 2 Max...the RFs are off the meter up close.

Bought max 2 with solar panel combo. It malfunctions and called last 3 weeks their customer service. No one there to answer. Finally when they did answered my 30days return policy expired. They’re not even responding to my email. I guess They sent you working unit.

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.

Nice review 👍...I called them power bank.. It hurts my ear hearing solar generator.

Question i have a champion generator, so can i charge the Delta 2 max, with it even though it's not a pure sine wave generator? Is there a way to convert it to produce clean DC?

So the solar input is 500watts each? Or 500watts total? On the two pv inputs.

Hi can i connect my delta 2Max to a delta 2 Smart battery

in Amps what is different on xt60 vs st60i ?

Not only do they not include the XT60i cable, they sell it on the website for $25 USD (not outrageous), but it's $54 CAD (WTF Ecoflow? That's robbery.)

I wish the grab handles were foldable. They massively increase the footprint of the device.

i like the idea but an EMP could destroy the electronic parts inside the ecoflow tho, making them useless

Some things you dislike about the unit, so make sure you watch to the end? I left after that comment.

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

Would 2 Delta 2’s connected together be equivalent to the Delta 2 max?

How would you hook up an emp shield for an apartment

Could they not at least put a mppt and dc outports on the extra battery!! grid down or being reliant on the main unit is 50 percent worthless IMO!

I'd like to be able to record music out in remote nature. I would need to power the following: MinisForum Ryzan9 HM90 Micro Pc Portable 4K display (has rechargeable battery) Audient Evo8 recording interface DarkGlass A/O 900WATT Bass amp FX pedal board with various 9v ac units (between 2 - 5 at a time) I'll be tracking bass, drums, & vocals for varying lengths. The bass amp would not be driving speakers, but rather running direct into the recording interface. I have travel drum kit and all the gear is portable; This means the solar unit would need to be as portable as possible, but strong enough to run the above for at least 4hrs. I know this is niche but if anyone can help I'd appreciate it. I can only track drums or bass while I'm alone, the 900wt amp is one scenario, drums & vocals will just be the mics going into the interface into the PC. I'll also being moving into a 5th wheel and using this same gear in the garage area. I'll want the best modular long lasting system with the fastest solar charging available when the time comes. For now, just need a mobile solar rig. Thank you Infinite love & gratitude from Colorado!

Bluetti expansion batteries can act alone. Ecoflow is way behind bluetti on that and when you are investing money like this, no mppt on the expansion is a no for me

5521 I use direct for my Boze mini speakers dc to dc

I want to power a 2.5 hp motor in a power outage will it work ?

Just cancel my titan order and got this instead.

👍🇨🇦🤠

Nice info but bro, can you stay on track😅

I always used vehicles name no matter what vehicle it is if it's a car is a car if it's a truck as a truck is a man I say then if it's an SUV I say SUV if it's a suburban and stay suburban just like I have an Android phone I just called it a a phone or cell phone and I don't got a smartphone and I don't got one that'll charge by sitting on top of a generator either.

I think the 12V is pathetic. It won't even run a diesel heater.

I think they are all still way overpriced. It's not that hard to DIY and so much more affordable.

This unit should of had 1400 watts of solar. 700 each mppt. 6kwh 1000 watts is not enough. That 6 plus hours of perfect conditions. It will never happen. 🤷🏽‍♂️

PPS/MMP/Ben👍👍👍Ecoflow customer service👎👎👎Ecoflow products👍👍my 2cents🤨

The smart generator has way too many well documented issues on starting and not worth the cost until they fix the problems. You’re better off buying an inverter generator for half the cost of the smart generator.

many design flaws and a frustrating to use dc. and especially the solar limitations per channel.

AI is crazy

Poor review, not focused on the unit itself but rather an overview. Operating temps are very important? Real world use ? And no mention you received all their products for free

Tik Tok? Why would you post on the CCP app?

Most portable power station manufacturers charge EXTRA (over-priced) for cables. It's an ASSHOLE move! One manufacturer could gain considerable good will over their competitors by including cables and NOT being a dick!

still a useless battery system until they get short cabled right angle connectors these are just more chinese junk, I shouldn't need 3 feet of side space to connect them together.
