Maybe I missed it, or maybe it wasn’t easy to see… so how does the device connect to the vehicle starter battery(?)

[@johnnysweekends]

The same as the battery on the bench in the beginning. Couple ring terminals but they recommend negative to the frame.

[@tracker9]

Great video bro! Does this thing work with other companies solar generators ? I’ve been looking all over for this answer

[@johnnysweekends]

No unfortunately its part of the EcoFlow ecosystem 👍🏼

[@johnnyrodriguez276]

Does it work for River pro 2 ?

[@Blztrls]

I’ve been alternator charging my Delta 2 Max with 2 Victron Orion 12 to 24 V DC DC chargers turned up to 30V and charging through the solar input ports. I get about 850 Watts charging speed. Cost $280 + cables.

[@johnnysweekends]

How many amps

[@Blztrls]

@@johnnysweekends the Ecoflow app only shows the charge rate in Watts but you can work backwards from that to get the amps. 850Watts @30V = 28.3A at the solar inputs, @13.3V at the input to the Orion DC to DC the current is about 64A. My alternator can output more than that so I actually have a 460Ah Epoch 12V battery charging from the alternator then the battery connected to the Ecoflow through the Orion DC to DC converters. It’s a messy system but I had bought the Ecoflow Delta 2 Max before I realized what a hassle it would be to charge it from the alternator. In hindsight I would never have bought the Ecoflow unit.

[@winstonwolff]

Same here. But I have a ecoflow ev adapter also if I need 2800w charging. Problem is finding level 2s that work while travelling

[@Scat.original]

@Blztrls Is there a video and part list available?

[@Blztrls]

@@Scat.original there’s no video I know of that details my specific method but there are some that detail how to use a 12v to 24v converter to boost the input wattage into Ecoflow or other systems. It’s fairly straightforward just get 2 Victron Orion 12V to 24 V converters, there is a dial you can turn to up the voltage to 30V. Then hook the output to the Ecoflow solar inputs using an XT60i connector. Make sure you use a genuine XT60i connector as the XT60 connector will be recognized as a low amperage connector and limit you to about 100watts. Also make sure you use thick cables on the input to the Victron Orions as it will be pulling about 70 amps. I got all my parts from Amazon.

[@stevenshircliff393]

Love it. I figured out over a year ago how to do this. Insane price but not unexpected from Ecoflow.

[@JenkinsUSA]

Hello, I have one Delta Pro and no extra batteries. Can I use this charger and the EF Dual Fuel Generator at the same time, using both battery ports and two XT150 adapters?

[@sunseeker8457]

Ok this is a bit of a game changer for vanlifers one the move. Instead of using the almost useless 12v DC charger (it's more of a trickle charge at around 100w). This can do some real charging! Thanks for charing.

[@johnnysweekends]

Yes, yes it can!! 👍🏼💪🏼

[@winstonwolff]

There are several devices from reputable companies that can charge alternator to battery dc/dc. I have 1 that charges around 420w while Im driving and it was $175 fuse, cables & charger together. Add in solar or a dual battery system etc and 800-1000 watt charging is possible. For $600 Ill wait for a sale. $350 max for this thing I think because it has reverse charging ( who is using that? ) and works with the app and is clean and easy. $600 is crazy town.

[@AikoiEmil]

Cool review. A quick question I have renogy 100ah battery in my camping car. Other devices are hooked up to it as well. It also has charging from solar panel and when car is running. Can I connect this Ecoflow Alternator with these other devices at the same time? Is it safe?

[@johnnysweekends]

Yes you can still hook it to battery as the alt charger also has safety features. But if this is the normal cranking battery for the car you may want to look into an extra battery for other loads you are running. A normal cranking battery doesn’t have a lot of reserve. And although charger is really meant for when vehicle is running

[@AikoiEmil]

Yeah, I have RV sub battery. Another dumb question. How do I protect myself from getting electrocuted when attaching these cables to renogy battery? 😅

[@johnnysweekends]

@AikoiEmil don’t touch cable to the metal lol. Positive cable first then negative.

[@theyclash1984]

What are the power losses when transferring from ecoflow to 2nd battery and vice versa?

[@littleblue4x4]

Good video. Wish I'd seen this sooner. I got a DC-DC charger from Renogy on black friday for my truck camper but this would have been a perfect solution and super easy installation. I like that it's bi-directional too.

[@johnnysweekends]

Exactly as you drive it can easily power up a decent size power bank and coupled with solar even better. So class C, sprinters or vans and more can really benefit from this. Is it the cheapest option? No, is it the simplest….by far!

[@Jasonoid]

@@jasonbroom7147 Keep in mind the Victron 12/12-50a will charge a power station at only 120 watts due to the low voltage (12v output).

@jasonbroom7147 they are pushing it with the 6. At the full length makes ya wonder if 4g would have been better. Not sure if using GaN tech makes enough difference in temp and thermal melt down lol. A full load test for a couple hours is needed. I only ran it for 45 mins max and it was warm but nothing to be excited about.

This is very cool! It's kind of a perfect way to connect a server rack battery to your EcoFlow Delta in addition to working with your alternator. Awesome video Johnny

[@1FAST91SONOMA]

how would this allow you to connect a server rack battery at all? It only outputs to Ecoflow batteries.

[@todd.parker]

@@1FAST91SONOMA Johnny showed the input being connected to a 12v battery to simulate a car's alternator so that shows you could connect a bigger battery to recharge a Delta and act as a more affordable expansion battery. Not sure if this could recharge the battery though, maybe Johnny can let us know

[@johnnysweekends]

@todd.parker input and output is 13.8/27.6 so no 48v systems. 24v only…👍🏼 but no directional. But I think charging will only get you 95% since float is about 27v on a 24v system

[@USAMOTORHOME]

My ecoflow pro is the one that have the 30 amps outlet on the front of my device. I bought it and they give panels and alternator charge as a Father’s Day promotion. The problem, my device don’t have the port to connect my ecoflow delta car alternator . Wondering if they sell one adapter 😮

[@johnnysweekends]

Yes you need the smart generator adapter but it may be out of stock…I cant seem to find one at the moment. Contact them

This would be a good product if it worked. I’m sure it works for you and I’m very happy for you. There are a bunch of posts on Reddit that explain how unhappy many of us are with it. I bought mine in May and it showed up a couple days ago. It was bought with the EcoFlow Delta 2. Right out of the box it was throwing error codes and I was told to update firmware. That didn’t work. I haven’t gotten much help from EcoFlow at all right now. It’s not much more than a paperweight to me.

Get on the facebook forums also go into app and go to the help area to get a help ticket going. Towards the bottom.

[@QuachMD]

Great video! I'm definitely picking one up. Just wondering, though, what charger is that which you hooked up to the battery?

[@johnnysweekends]

I’m using the 85 amp amzn.to/4b9MG4o

[@SeeSaw99]

I use a Delta pro max in my 18-wheeler for tv, cooking, etc. It took a while, but I figured out how to get my 1800-watt inverter to recharge my delta pro max. I have it set at 1000w, and it takes around 2 hours if my delta is ever very low. This unit will definitely put a work your alternator so you should be very mindful of that. I obviously have a heavy duty alternator and after an hour or so, I can see my alternator amps begin to dip. The only problem with my setup is that I have to remember to turn off the inverter whenever I shut off my truck, sometimes I forget. If this unit will shut off automatically, that is a huge plus and I would buy this just for that feature alone.

[@johnnysweekends]

In charge mode once truck is off it stops. So its just at idle until you turn it off or turn off the EcoFlow delta unit

[@SeeSaw99]

@@johnnysweekends sweet. Thanks

[@lawrencelin272]

did you get some answers to the questions you posed? my v6 gas/petrol has 130amp alternator (but is 15 years old!) and fresh AGM battery with 70 AmpH how much wattage can I expect to pull? What's a safe setting? Also, let's say my car battery goes flat at 11.5v? watt hours of the ecoflow delta 2 should I expect to 'reserve' as emergency? is the reverse an instantaneous 'jump start' or i will be waiting some time for the AGM car battery to have enough current to turn the starter?

[@johnnysweekends]

130 amp alternator might be on the low side if AC in running and lights or other systems. You may want to look into a HD Alternator for your vehicle. And it does have a boost feature but haven’t tried it.

[@FWDXPL]

Does the power hub (with power kit) have a feature where it can send power back to the chassis battery via alternator cable?

[@johnnysweekends]

It can send back through the DC out at 13.6v or 70amp max. This is the same as just the normal dc out for dc loads but I guess can charge a battery as well. Although I have not tried it. I may send the DC out at 24v then to a battery charger and step down to 12v. So a 24/12V charger. Im changing my setup and getting rid of my on board solar setup for the house battery and adding more solar to dump into power kit and then dump the excess to the house from 48v to 12V so that will actually be easier. So I will run a 15k PK into a 2600wh 12v Battery.

[@FWDXPL]

@@johnnysweekends Thanks!

[@TheSimplePreppers]

Did you ever try hooking some solar panels to your power station, and see if it charged both start battery and power station at the same time? I'm just curious if it will work like an RV DC to DC charge controller setup, if everything is hooked up, and vehicle is turned off.

[@johnnysweekends]

I did do dual charging dc from solar and Dc from alt charger so it will also charge start batt and function as it should. More firmware updates are coming which will allow and unlock more features that didn’t work like battery side voltage verses power station stats

[@anyalpine]

I would love to see if it does alternator charging and solar at the same time.

[@johnnysweekends]

Yes it can!!! Funny I filmed it but not sure what happen to the footage … just gone 🤷🏼‍♂️ But it shows solar in the app and then dc coming in separate. I had about 1000 watts coming in. 180 solar and 800 alternator

[@texasgrillchef8581]

For those who use a winch. When you need to use your winch, turn off the charging on your ecoflow from the alternator. If it’s charging at 800 watts. The winch won’t get enough power. Especially for harder winch pulls.

@@johnnysweekends so frustrating dealing with ecoflow, I bought delta pro, alternator charger, wave2 and add on battery, now I need adapter and cable to go from charger to delta pro, and connect wave2 to delta pro it needs to be through AC port which is loosing about 100w doing dc-ac-dc , there is a slow dc connection on wave2 I believe its for car charger but that will take forever to charge, meaning AC is the only option. Or Im missing something?

Can you plug in the 12v plug into the solar input see if you can get more than 800 watts?

downside to this is that, if you max out the Delta 2 Max, both ports are going to be taken up. so you can't charge all three batteries at once etc, you are limited to only 2. even then I'm definitely getting one

[@1kzrider]

I like it. Would be awesome for things like this to start working its way into market. I have seen some folks build a small HP mower type engine with alternators for charging battery banks. But, it would be a great setup if a company made a setup that you can plug into car and charge your off grid battery setups for low power generation days. I like the ecoflow but, since many people already have off grid components in separates would be nice for a universal setup to be used without having a main component as the ecoflow.

[@johnnysweekends]

Agree, there is always an optional build you can do that’s universal. But when things are more proprietary then you are kinda stuck. But again most companies make products to work with their products. It like apple, why would they make something compatible with Samsung 🤷🏼‍♂️ or any other company. Needs to be a 3rd party to make some universal set up. But for those who want quick and easy this is more for them.

Well using GaN tech now they run much cooler and way more efficient. I let it run for only 45 mins and it only got warm. But it’s not tucked into a wall or storage area and it was 68 degrees out.

I mean, how do you charge the Extra Battery if there is only one output from the Delta 2, and that is hooked to the alternator charger? 2. Does this unit get hot at all, as I am considering mounting it under the driver's seat. 3. Can the Delta 2 charge via the alternator charger and solar at the same time?

[@johnnysweekends]

Yes you can charge with Alt charger and solar at same time. I dont have enough testing as it was a cool day and an open area for me to tell you if that’s a good spot. I would have it in a more open area if you can. It got warm but not hot in a 45 minute test at full. As far as charging D2 unfortunately there is no way to charge both. So it would be manually or upgrade to D2M…

[@insaynbcr]

@@johnnysweekends Awesome that the solar and alternator can charge at the same time. As for upgrading to D2M from my D2, it wouldn't play well with my setup. The D2 and D2 Smart Extra Battery each fit perfectly behind a seat in my 17 Tacoma double cab. The cable between them just fits as well. The D2M is just too wide + the cabling on the side. In most cases a single D2 is more than enough for my needs, but I couldn't pass up a deal on a second D2 + the Smart Extra Battery shipped free for $1099, when the Smart Extra Battery was $750 by itself at the time.

[@TheCornucopiaProject-bd5jk]

Not sure if I need alternator charging but… When I try to use standard 12v 100ah batteries to act as an expansion battery for my delta, I run into the problem of a hard limit. 12v x 8a = 84 watt, be generous and make an even 100 watt. That’s the max dc charge rate I can put into the EcoFlow from a standard battery. With this dcdc charger, I can fully utilize the EcoFlow AC output while still putting a decent amount of energy back in. Or simply letting it do its pass thru charging. This is a cheap alternative to those super expensive expansion batteries.

@@johnnysweekends I was hoping for some charge profiles for different chemistry’s for connecting to the camper house battery. I believe we will see that soon.

@jjsantos3292 agree. I think after app updates which should come soon since this hasn’t officially been released yet.

[@DanBrown1010]

I am a Delta2 user with extra battery setup. It seems this can't be used at the same time as the Extra battery for Delta2, since only has one port. Any chance the alternator charger can plug directly into EXTRA battery and charge it independent of the Delta 2? That port looks to be the same format on both the Delta2 and the ExtraBattery? Not sure how safe it would be...but may offer another way to charge up your extra battery? PS - Thanks for the video and the savings links - great job!

[@johnnysweekends]

Yes you can swap it from delta 2 or the extra battery and charge direct just like the smart generator

[@GameTrailblazerX]

Hey mate if we have a hybrid car like range Rover porshe Cayenne can we use this alternator to charge ev battery

[@johnnysweekends]

It will only feed the starter battery. Even then charging the EV would be slow at only 800 watts.

[@GameTrailblazerX]

I taught if we could charge that way then we don't need to charge again 😂😜 lifetime free 🆓😁

Nice video and product from Ecoflow! Johnny.. Will this charge my 48v lithium battery bank from a Silverado 2500? Specs say it would.. I'm ready to pull the trigger but thinking about output cables/adapters to connect to the 48v server rack lifepo4 batteries..

[@johnnysweekends]

Says 12/24v into EcoFlow products

[@NigelS-vx6zm]

What is the minimum size alternator to safely charge at 800 w without damaging the alternator

[@johnnysweekends]

It uses up to 65 amps. I would say at least double that for you to be able to still use all car systems and not over strain the alt. Or you just dont have every single thing on in the car.

[@serignebabou4306]

Does it work with a 48V battery ?

No 12/24v

Can you set charging speed limits in the app so it doesn’t draw as many amps?

Sorry I don’t know anything about your vehicle. Best to go to a auto parts store and see what HD alts are available for it

[@zgomez68]

Will this only work on ecoflow? Or can it work with anything with a xt60?

[@johnnysweekends]

Only with EcoFlow as it uses the xt150 connector and data pins

[@rbrt_lux]

Will this work with the original delta?

[@johnnysweekends]

No it wont. Needs the xt150 connector

[@jakemaughan3818]

how many volts does it push to the battery in reverse charge mode? Trying to see if it will meet the specs for an AGM battery since they like 14-14.5v to charge all the way rather than the alternator default of 13.8v

[@anyalpine]

It would be nice to be able to specify battery type or change voltage/amperage settings.

[@johnnysweekends]

In the specs sheet it reverses the same spec. 13.8/27.6v

[@johnnysweekends]

Im getting more info on this but i think its auto like a charge controller or battery charger. Most can tell battery charge parameters now, like a smart charger

[@PaulStaley-gg5fk]

Thank you for this video you just answered a question I had sent to EcoFlow support that they said wasn't possible. I asked about the reverse charging and how that worked. Answer they sent me and I wonder if this was just an AI response if the documentation is still in the works. "Based on the information provided in our documentation, there is no specific mention or guidance on a reverse charging setup that allows the Delta Max 2 to charge house/start batteries directly. Our current product design and documentation primarily focus on charging the Delta Max 2 and its extra batteries through various methods, including solar panels, AC shore power, and alternator charging while driving." "However, your scenario of charging the Delta Max 2 while driving and then using it to charge your house/start batteries when stationary, although innovative, is not directly supported with the current design and accessories. This setup would require additional equipment, or a custom solution not provided by EcoFlow at this time." "We appreciate your innovative approach to utilizing our products and understand the convenience such a setup would offer. Your feedback is invaluable, and we will forward your suggestion to our product development team for consideration in future product designs or updates."

[@johnnysweekends]

It’s so new that it’s still beta technically hence it wont deliver for a few weeks. New firmware is still coming. Im still limited to what I can do so ill do an update when the firmware updates and its closer to release and i have more time with it.

[@Espiritiv]

So this is just an alternator B2B charger for Delta Pro to match what their Power Kits have for Alternator charging built in? Can the Powerkit do 2 way charging yet? Didn't think so

[@johnnysweekends]

Yup, and yes the app was updated to be able to charge the other way now. Although I haven’t tried since mine is in a towable RV and not a van or something with house batts. But I need to try the RV house batts I guess. Have to try it out.

[@Espiritiv]

@@johnnysweekends nice!!!

[@scottkindley]

So in an RV how would this interact with onboard converters?

[@johnnysweekends]

It would act the same as when I plugged in the charger. It would show constant voltage and be able to charge at 800 watts. But check your converter rating. Some can be pretty low at only 45 amps and some much higher like 80 amps. I would check your model

[@rjbfreelander2]

Looks like it is only useful for the current generation, Delta series of Ecoflow units. I have one ( Delta 2 Max and Extra Battery) but would be good to use it on the other units also like the River Max, River Pro and River 2.

[@jorgerivasam]

One question I have three EcoFlow Delta Pro battery. my Ford Transit. If it is compatible

[@johnnysweekends]

It will work with delta pro but need the smart gen adapter….. 👍🏼😀

[@jorgerivasam]

If I have it, I brought it when I bought the three Delta Pro batteries. What I see is that I have to plug it into the battery ports and have to disconnect the battery every time. I think it's wrong. 🤔😵‍💫 @johnnysweekends

[@zizhaolaisuimuqu]

Great product makes me hesitant to buy the anker powerhouse 767, but a charger like this selling for 599 might be a bit pricey for what it is. Ecoflow has also released a 500w charger in some region that uses the xt60 connecter, which about 150 bucks, it is a much better deal compare with this one. But from the video this 800w charger seems to use a fanless design, probably thanks to the Gallium Nitride technology that brings less consumption. I probably wouldn't consider buying it in the short term, preferring to wait a year to get the right price or coupon.

[@PaulStaley-gg5fk]

But if you gave not bought a System yet, you can get a great bundle price with this in it.

[@Skdjiejxuje]

I wish it was able to charge 2 delta pros at once and just split the power or at least charge up one and then go to the next.

[@johnnysweekends]

Yea would a splitter

[@xavior718]

I think I’ll wait for the second gen. Who knows, the second gen might be able to charge over 800W.

Could I potentially use this alternator plus a Delta Pro battery hooked up in my van to have the van AC running during summer nights? Would this maintain the van 12v battery charged while using the AC? Obviously, with the engine turned off. 🤔

[@johnnysweekends]

You cant use this with the starter battery and engine off. You’ll quickly drain the starter battery and it wont have enough to start. Then you’ll have to reverse charge using power from DP. Starter batteries are not meant to be drained to low levels as they are damaged easily and should always be in the upper voltage range to extend life. This is a meant to charge as you drive and not used while engine off.

@@johnnysweekends the idea would be to turn on the reverse charge and use the AC. This way, ideally, I would be draining power from the starter battery while it would be charged by the Delta Pro. Is it really not possible? This would be ideal instead of needing yet another big (big for a small van) appliance like the Wave2.

[@johnnysweekends]

Are you talking the vans AC system? Like the AC system while driving that comes out of the dash?

@@johnnysweekends yeap, this one. PS: I don’t understand much about cars, I know this would quickly run dry the starter battery if left on without engine running. But as I was thinking, if the Ecoflow alternator charger can reverse charge, I would turn this function on, pulling the power from the Delta Pro to the starter battery, and use the van own AC. Now, is this possible? Would have any issues doing this? This would be amazing if possible. This is for a VW T5. So, there’s not much space to have a Delta Pro + a Wave 2 AC. If I can avoid getting the Wave 2 would be great for space saving.

[@johnnysweekends]

Unfortunately this is not possible. When the van is off the AC doesn’t work unless the engine is running. If you turn the key on the “fan” will work but not cold air. When the engine is running it turns a belt that the Ac unit/compressor is attached to. That’s the only way the cars AC system works is if that belt is turning. And that only happens if you turn on the engine. So unfortunately what you are trying to do wont work. Sorry…🤷🏼‍♂️

[@GregsYouTube]

For my use i think id be ok with getting only 500w charging from a 100ah lifepo4 battery. But if i wanted the full 800 what is the cheapest way to make that happen? I didnt quite get the device you were using to do that. What is it, how much, and are there more than 1 type of device for that? I'm also assuming the alternator hub allows you to charge external battery with up to 800w while simultaneously charging delta 2 with a gas generator or solar or both, right? I got to get one these I've see they're down to $400 now on ecoflow's eBay store and if they drop any lower I'll be forced to buy one that's for sure. I like the fact for emergency power outages to be able to use car to charge delta 2 in case gas generator failed or use both car and gas generator at same time because I have a delt 2 and delta 2 max units. This is nifty too if I go camping and want to charge delta 2 fast fast fast. Looks like a great product!

[@anyalpine]

I would love to see it running at max for 1hr and see what the surface temperature is on the charger. This could impact where/how people install it.

[@johnnysweekends]

Agree I need to have it mounted and see how warm it gets being on for a while verses the 45 mins I ran it on a 68 degree day. But GaN tech is more efficient and runs much cooler. It got warm but not really. Just enough to know it’s doing something. But again not great test conditions on a low temp day and not mounted

[@Truth-op3be]

The picture you have on KZbin says 3600 W Ecoflow and the one you displayed is different. Why?

[@PaulStaley-gg5fk]

Curious what the outcome of was for the reverse charging. Did it gradually stop charging and sense when the battery was charged in your Truck? I am contemplating if i should go this route and would be curious to know your thoughts. My setup below. Duramax Shuttle bus with dual alternators feeding a big 400-amp dual isolator with 2 start Batteries on one output and 2 House Batteries on the second output. I also have a Delta 2 Max with one extra battery with 1000 watts of solar coming in. My thought is to run everything 12v related off the House Batteries and everything AC related off the Delta 2 max. it seems like this and the reverse charging capabilities i would be able to keep my house batteries topped off with solar when the Engine isn't running. Only downside I see is not being able to use Lifepo4 batteries for the house batteries but not sure that really matters since my 12-volt load will really be low. Let me know your thoughts on that. Would love some feedback.

[@johnnysweekends]

This system is compatible with all battery chemistry’s and will charge the house batteries. Lithium has its own bms so it will stop charging once full. But needs the 14.4 volt to fully top off. So if it only 13.8 max then it may only charge the battery 95%. Not sure. This is still so new and in beta more updates will be coming out. And im sure maybe added features or accessories. Who knows. They added extras to the power kit so will be interesting what else this is doing in 6 months.

[@jasonbroom7147]

Great video on a very expensive, specialized and proprietary product.

[@r.kitt.3987]

You can accomplish the same thing as this product with an inverter connected to your vehicle battery for less than a third of the price of this thing. I've been doing it for years. $600 for this is a joke.

[@johnnysweekends]

Of course you can, just like anything there is always a cheaper way. But some people like integration and plug and play. Especially if not comfortable with wiring and more.

[@jasonbroom7147]

@@r.kitt.3987 - Yeah, not exactly. Charging anything other than your vehicle's lead-acid battery, using the alternator, is not as simple as you seem to think it is. This isn't just about using an inverter, and connecting an inverter directly to your vehicle's battery comes with its own set of problems. This product is a lot more sophisticated than you are giving it credit for.

[@r.kitt.3987]

@@jasonbroom7147 bullshit. I've been charging my ecoflow devices off an inverter connected to my vehicle for years. All I do is scale back the amount of wattage so as not to overload the alternator. I've had zero problems.

[@jasonbroom7147]

@@r.kitt.3987 - Yeah? How do you scale back the wattage? The EF app or settings on the device? How do you prevent your battery from being drawn down too far? I'm not saying it can't be done, or shouldn't be done, but the inefficiency is pretty absurd, when you really look at it. You're using fossil fuel to spin the alternator, which puts DC power into your SLA battery, then you convert that to AC with an inverter, which your power station converts back into DC to charge its battery. You're losing at least 20-30 percent of the actual energy being created in those conversion processes.

[@1FAST91SONOMA]

Not really. Too expensive and limited. $600 for a bi-directional DC-DC charge controller is pretty bad. I got a 50A DC-DC/MPPT controller (does alternator charging as well as solar, all in one and it also charges the starter battery like this one does) and a 2000W pure sine inverter for the same money. 2000W>800W by a lot. If you wanted to power an entire build from Ecoflow products exclusively and you hate wiring I guess this makes sense but anyone who isnt afraid of connecting +/+ and -/- will get more for their money by running some more wires
