Portable Backup Power For Emergencies - EcoFlow Delta 2 Max

[@T-Mo_]

Informative video. Looks solid. Watching the testing got me curious of the wattage used by my window fans. Between 42 and 66 watts depending on speed and fan. So they'd last a 24hr+ with the ecoflow. Also tested a small Ryobi hybrid ac/battery fan. It only uses 14w on high and 6w on low. That would last a week+ depending on how much the ecoflow inverter and circuit board/display use up.

[@GreyManPrepping]

Thanks TMo, and that's really cool you did some calculations. I think I'm going to buy one of those devices that measure watt hours and amp draw for future videos. Time to upgrade my videos 😆 Thanks for the support! 😁👍

[@JRCHomesteadTexas]

I enjoy your reviews, especially on solar products. Thanks Grey. Remember y'all to Pray, Plan, Prep

[@GreyManPrepping]

JRC I really appreciate that, I put more work into these types of videos than folks would assume. Just this one alone was over 6 hrs. So again thank you so much 💛🙏

[@commonsensepreparedness5841]

IMO ecoflow is one of the best companies in this market of solar genies

[@GreyManPrepping]

Definitely in my top 5 😁👍

[@unbroken1010]

Maybe but they are so expensive

[@GreyManPrepping]

@@unbroken1010 unfortunately, I remember my first power station I bought years ago it was $800 for like 700W. I've seen prices drop per watt due to competition in the market.

[@lanareed4574]

This is nice. I like that it is not real heavy so us older folks can manage it. I would use it in power out for fans and refrigerator or cpap machine.

[@GreyManPrepping]

It's the lightest unit over 2000W I have had the pleasure of reviewing so far. It would easily power the devices that you mentioned. Thanks so much for watching Lana 😁💛🙏

The Delta 2 Max with 2048 Wh weighs in at almost 52 lbs! The Delta 2 model with 1024 Wh weighs in at 27 lbs! He mis-spoke at the beginning of this video!

[@themoldysoldier]

Thanks GreyMan. I sent this to my brother who is currently looking for something like this (thank God; been telling him for a few years to get ready).

[@GreyManPrepping]

My pleasure Moldy, and yes we truly need to be prepared. Once I get the 2 other batteries for this unit it will definitely be my main unit for powering my freezer, fridge, lights, and fans. 😁🤘

[@brianmachado4533]

I bought a Delta 2 Max for emergency prepping just this month. Ran some tests and so far very pleased. i got it mainly to ensure I can run my gas furnace, fridge, microwave and some lights etc. Using it to replace a gasoline generator. Bought a second 220w solar panel to make recharge time more reasonable when limited to solar input. All this because of a three day grid down event about 8 years ago after an ice storm in southern New Hampshire. BTW...good video.

[@GreyManPrepping]

It's a great choice, I use mine to run my deep freezer and emergency lighting. And thanks so much for the feedback. Have a great evening!

[@oldmanpreparedness131]

I really like the size of it. I have the older delta max, but I really pondering this one. Thanks for the review Grey

[@GreyManPrepping]

My pleasure, I have the delta 2 which I really like but this unit has better options and a bigger battery. I'd love to get a whole house solution, but that's way out of my price range currently. Thanks for stopping by brother 😁👍

[@sixshooter4570]

Those PV1 & PV2 are XT60I connecters which have an extra wire which allows it to carry more current than the standard XT60 cable. There not Anderson connecters.

[@GreyManPrepping]

Thanks for the clarification, after the video was out I saw the error but at that time it was too late 🤷 So I always hope folks like yourself share information like this so that other viewers can see the error. Most of my base viewers will email me and I will pass on the corrected info. Have a safe Independence Day 👍🇺🇸

[@Sylvan_dB]

They don't carry current thru that 3rd wire, it is used just for signaling. It is too small to carry much current. The two power pins are good for sustained 20-30 amps which is plenty for the 2 max. Still trying to verify (I expect my delta 2 max to arrive tomorrow but the solar stuff shipped separately and is a few days further out) the exact connection of the 'i' pin but it sounds like it is wired to one of the other two pins and the delta max detects that to enable full power charging. The other theory is that the 2 max just detects voltage - under about 30v it charges at 8-9 amps assuming a cig lighter socket connection, but 15 amps above that and you don't need that 'i' pin at all.

[@irvinoneil]

I would like to see it hook up to a transfer switch like you mentioned in the beginning of the video

[@GreyManPrepping]

I hope to one day have that option. This home is a temporary investment opportunity. Once we move to our forever home, that's the plan.

[@irvinoneil]

@GreyManPrepping I'm in the same boat. That's exactly what made me ask. I don't want to invest in a major set in this property. I would like to at least be able to power the lights along with the other things I already use it for. Such as refrigerator, washing machine etc. But I connect those directly to the delta max. Can't do that with the lights

@@unbroken1010 oh I agree for sure. 18 years or so ago I was without power for 3 weeks mid-summer, with my 3 young sons at the time. Truly a big wake-up call, which lead me down the path of emergency preparedness. You really do get very creative in those situations 😁👍

[@tbone45040]

i dont understand why the delta 2 max (and other delta power stations) is not able to be charged at an EV station like the delta pro is. the ability to have 2 setups and rotate between them, alternately charging one while using the other is a great asset.

[@GreyManPrepping]

Agreed, That would be optimal. I hope future iterations add that option

[@Sylvan_dB]

Cost and market segmentation. I'd like to be able to connect two in parallel for more capacity or in series to get 240v like the Pro. But I didn't want the weight of the Pro. I wanted the weight of the Delta 2, and the dual solar input of the 2 max. Oh, I also wanted the expansion batteries to have independent solar charge and D.C. outputs like the Bluetti. Oh well. I bought a 2 max.

[@deaconprepper8370]

Howdy Grey, good review, is reviews all you are doing now?

[@GreyManPrepping]

Hey Sarge 🫡 How are ya? So currently I'm so behind on reviews that there is a lot to catch up on as well as other companies that are reaching out. I've been mixing in my garden videos, and a couple of lives throughout the month. My daughter is starting summer break so I hope to do 3-4 lives June through August. I really enjoy doing reviews of gear but there are a few aspects of my channel I miss. It's more of a time thing. Between work, family, and a few other personal endeavors my youtube time has been very limited. My apologies brother.

[@deaconprepper8370]

@@GreyManPrepping hey, no appologies necessary, I was just wondering, I miss the report videos and different topics you used to cover, but real life comes first! No worries, I still try to catch your posts but my health is not great and they have upped my pain management meds! Ugh.. just for your info on these solar power systems, if you get a 2400 watt unit, and only run a 240 watt appliance, it will only last 10 hours.. people need to realize of they suck all 2400 watts they only have 1 hour or less of power.. take care brother! Many blessings 👍

I truly understand that brother and I will definitely be praying for you my friend! God Bless

[@pitbuldog]

i can never find a real good video on the noise, for example when its charging with solar panels and using the ac how much decibel is the ecoflow producing then

[@GreyManPrepping]

On this version at the max over 15 mins they produced at its peak around 46.1db on average it was around 45.4db. This was a big difference from the original which hit around 60.2 db on max load hopefully that helps a bit. I'll have to start adding that test to my videos.

[@johnhouli3450]

Grey man how ya doing, question why is a red 2 wrenches icon on the screen.

[@GreyManPrepping]

This unit was a beta unit given to me for testing they eventually sent me a production model, and this one went back.

[@jimstamos5672]

Can I charge the delta 2 max extra battery by itself with solar? Otherwise I'd have to shut the delta 2 max down when it runs out to charge the extra battery plugged into the max via solar. That would kill always having a backup

[@GreyManPrepping]

Unfortunately, only if you have the smart generator by EcoFlow, now I'm unsure if you could use other hybrid generators as I've never tried.

[@wes326]

How long could you run a fridge, lights, and furnace fan?

[@GreyManPrepping]

Honestly, it all depends on the wattage of each thing you're trying to keep power to. After adding that up you can use the rated watt hrs of the unit to get an idea of how long the unit will power those devices.

[@johnhouli3450]

Is their a way of connecting a 30 amp plug to the machine via the hub

[@GreyManPrepping]

I don't think so on this model, but I know there is a pro line like Delta Pro 3 has that capability.

[@mikecherico3500]

If I get the max / 6KW ( add 2 batteries) to this unit, can it run a 220V, and can i just add a transfer switch and power most of the entire home?

[@GreyManPrepping]

This unit is not rated for 220V Ecoflow does have a unit that will run 220V if you click the link provided look for the "EcoFlow DELTA Pro + Smart Home Panel" which fits what you're looking for. Hopefully, that helps a bit or at least steers you in the right direction. Please feel free to reach out if you have any further questions. 😁👍

Hi, what's the btu (how many ton) of the air con and does it have an inverter?

[@GreyManPrepping]

The AC unit is 10,000 btu's or 8.33333×10-1 RT (power) tons. For example, 12,000 BTU is equal to about 1 ton.

​@@GreyManPrepping Thank you for the info, you wouldn't know if it has an inverter, would you?

[@GreyManPrepping]

@al00shi honestly, I'm not sure. My apologies. I've had that unit about 6 years now.

[@prepperdan]

So after 3000 cycles is the battery completely useless or is it just 80% efficient after 3000 cycles?

[@GreyManPrepping]

No, the capacity is reduced from 100% to 80% as with every power station as well as any rechargeable battery. Some of the cheaper brands may only have 500-1500 cycles. There's more science & tech to it. But I can forward the long version to you if you're interested via email. All my contact information is down in the description.

[@Sylvan_dB]

Any rechargeable battery degrades with cycles of charge and discharge. Specifically they lose capacity and increase internal resistance. They expect this battery to still have 80% of its specified capacity after 3000 cycles. Efficiency is not the main idea, but due to increased internal resistance there is a slight loss of efficiency as well - meaning when new you might put 1.05 watts in to get 1 watt out, but after a few thousand cycles you might need to put 1.1 watt in to get 1 watt out. This is called charge cycle efficiency or just charge efficiency or cycle efficiency. Usually the loss in cycle efficiency is much smaller than the loss in capacity, but the cycle efficiency does have a larger impact at higher rates (more amps/watts) of either charging or discharging.
