This is a full walk-through of the latest from Ecoflow - the alternator charger. It is a 3 in 1 once device that can fast charge your Ecoflow Delta power stations, but also reverse charge your vehicle's battery if it is dead, or can be used as a trickle charger in maintainer mode. This new alternator charger is simple and easy to install and is a great alternative to a dual battery system.

As you mentioned Casey, the app should allow a more precise voltage for shutoff in 0.1 volt increments instead of 1volt increments. This would protect the vehicle battery from life shorting deep discharge below 12 volts. If Ecoflow would allow the unit to be adjusted to lets say 12.5 volts for example the vehicle battery would have a much longer life. Keep up your great videos 😀

[@chrisdoeseverything123]

Just wanted to say thank for you this video. It answered a lot of my questions. As a result I bought a ecoflow delta 2 with the alternator charger since they had a $600 off sale for the pair for Father's day (also came with a 100W solar panel) and I used your code. Hope this helps you. I have a 2003 Ford E350 Amulance that I converted to a campervan. I have the same issue with the battery dying after sitting for too long. I originally use a 500W Jackery that does not have nearly this many options and charges super slow. Excited to start using this new system!

[@hardtruth2039]

We just picked up the delta 2 max, an extra battery and the 800w alternator charger on a great Mother’s Day deal. Saved $1149.

[@StartBuildingYourDreams]

Definitely cool! I see great value for that person that is an avid outdoorsman, off-roader, or overlander that doesn’t want a permanent install or to leave valuable equipment in their vehicle while at work. Personally I have 2x100AH Li house batteries and a Renogy 50A DC-DC Controller w/mppt for my Gladiator. My fridge runs 24/7 and have a 1000w inverter. It’s totally overkill, unless I start taking a microwave, hairdryer, or air fryer on trips, but cost less than most 1000w power stations on the market to assemble. The trade off for a fixed system is “dedicated adventure vehicle” vs using a gladiator as a truck to haul lumber, mulch etc. This definitely seems to bridge that gap for the 90% that use their vehicles for more than adventuring! Great video!

[@Dave_Gurman]

Great video. Though this is not a game changer, just a improvement (Ecoflow product only) on using an converter from your alternator. Victron has a few DC2DC CONVERTER options which also works. Pecron has a cheaper option (though only 500W) it can be used on all power stations.

[@Irideonandon]

I have a DC to DC charger and they absolutely do not operate like this. I'm amazed people with DC to DC chargers are not able to see the difference. This is a game changer but only the start of changes to come in the near future.

[@Dave_Gurman]

​@Irideonandon I said DC converter there's a difference. You're correct though looking forward to a generic plug in product with these functions that can charge any power station.

[@ferdm9646]

Car battery system is 12V does not mean you can discharge it all the way up to 12V! it will potentially damage the battery and next time you will try to start the engine it wont start. you will end up having a flat battery. you should never go below 12.6 if its lead acid for other batteries check the specs. Keep it up, Cheers!

You explained this system better than Ecoflow! I'm glad Ecoflow came out with this system. I like this idea better than solar panels or the Smart Generator!

[@Casey250]

Thanks!!

[@johntate5284]

I'm glad someone reviewed this and EcoFlow had some killer bundles with a Delta 2 or Delta 2 max where you get this for almost free. Pecron offers a nice alternative ($134) that is 500 watt and works with any power station as the output is via MC4 connectors so it goes into the solar input (only power stations with a solar input voltage up to 60 VDC) of most brands (Except Jackery unless you have an MC4 to funky Jackery barrel connector adapter).

[@markbergman2342]

do you have more details of that Pecron DCDC?

[@johntate5284]

@@markbergman2342 I got mine. The only real setting is a rotary switch that determines when it will send power to your power station. By default it is set to [0] which is 12 to 30 volts. I set mine to [4], which is 13.5V to 17V to ensure that the car battery is never discharged by accident. The biggest difference is that the Eco Flow one is bi-directional and can recharge the car battery which is something the Pecron doesn't do. The Eco Flow is also more efficient. By itself, the Eco Flow one is quite steep, it's almost free with some of the Eco Flow promotions going on the the Delta 2 and Delta 2 Pro.

[@cyclemoto8744]

DIY install with components (can be made portable) costs half the price. THose who don't have the skills, sure these products are good ideal but otherwise their not economical nor are they serviceable. Thanks for sharing. Cheers

[@lyfandeth]

Paying $600 for a charge controller with the proprietary plug that allows an Ecoflow to be charged at a reasonable rate is extortion. Ecoflow really could just tell us what input terminals will accept the more powerful DC charge. The normal limit of 10A is simply ridiculous. Even a USB-C 3.1 PD wall wart can supply more than the Ecoflow normally will accept.

[@jimmydoo]

As others have stated, your battery shouldn't be at 12v while the car is running. The battery should be at ~14v while charging. If its less then that it's very depleted and that's not healthy for it. Also, dual battery systems aren't only about capacity. They're also about amperage, which for some power hungry winches are a necessity. You won't get that with an Ecoflow as your secondary battery.

[@parkcitymacs]

I run an ecoflow with smart battery (4kw+). Maybe, I’m missing something but I just use a small compact Honda 3000W (EU3200) generator and it charges them around 2000Watts into the batteries. Generally, less than 2 hours, and I’m good for 2 to 4 more days. It uses so little Gas, it can’t be more than a $1 or more to charge. Super cheap, easy, and fast. The generator is so narrow it fits on the floor between my rear seat, back of by truck in the corner, or in a cubby in a trailer.

[@joeblow1942]

Is it the Delta 2 Max that you have? Are you saying you can charge the Delta and expansion battery from 0 to 100% in only two hours?

[@parkcitymacs]

@@joeblow1942 It is never a good idea to run LiPo batteries to zero (0). Sometimes as low as 10 percent sometimes as high as 20 percent …. But yes, about 2 hours plus, sometimes less. The main thing is that they are extremely fast to charge and the ratio of use is about 2 hours of gas generator charging, if we have had ZERO sun; that equates to 2 to 3 days of use which includes multiple microwaves (2 to 4 min each run) Morning and night, multi coffee (KRUPS), theater HomePods (4) speakers running on 110V. with 110V 4K monitor playing up a 4K movie usually a max of one movie at night, lights on… IF there is sun, then I only need 400 Watts on the roof for 5 to 6 hours, March to October, that is and never touch the small Honda EU3000IS generator.

[@dubious6718]

Cost more than this, weighs more and takes up more space. You also have to carry fuel.

[@parkcitymacs]

@@dubious6718 More fuel? the EU3200I has a small tank and can run 5 to 8 hours way more efficiently/faster than a huge car engine, sucking far more fuel , adding vehicle hours, at best producing maybe only 1/3 (66 percent more charging time required) the wattage with modifications compared to the small generator. That means you spend significantly more fuel, significantly more time charging, which if you are not driving means your car sits and runs for hours with that large engine to charge those Ecoflow Batteries for much longer. Just a gallon or so in that Honda, means you could charge (2) Ecoflow batteries up to 4 Times giving 8 to 12 days of total time on your Ecoflow. You would run out of food in a car before that. IT’s very light weight , easy to pick up with one arm, and small. It fits on the floor between front seat and the rear seat in trucks or even new Bronco.

Thank God Pecron makes one for everyone. 😂 It's only 134.00 after a special coupon. Reverse charging is not needed when you'll never use it. Just carry a Lithium battery jump starter. The trickle charging feature is a gimmick. You're draining the power station unless it's hooked up to solar. If it happens during the night? 😮😂 If you lose the unlock clip. You can use ring pliers

[@TheCornucopiaProject-bd5jk]

I ordered the Pecron model. Should get here any day now. Ordered on the 10th. It does charge at a slower rate though. 400 watt or so. I will be using mine to charge my … drum roll … EcoFlow delta from a separate lithium battery. That increases my capacity by 1280 watt. And since my old model Delta only charges at 400 watt anyway, it’s a perfect match.

Those inverters have losses you have to consider as well. The EcoFlow is dc-dc. At the 239 prime day deal, it’s a steal. If you aren’t using other EcoFlow gear, it’s probably not very useful though.

​ @user-jo4lr8it6p When you order your Anderson connector you can order the correct size contact to go with your wire size. Then 50 amp connectors can be ordered with up to a size 6 AWG contact. The 75 connectors can use 4 AWG contacts. Just double check which connectors work with which contacts. The different color connectors only work with the same color on both ends except for grey and black. Double check that also. Also be careful that the connector description actually says made by Anderson brand because there are lots of connectors that look the same but are not Anderson and may allude to being Anderson..

Do you think this charger will increase wear on my alternator? Should I upgrade my alternator or limit my use of the charger to protect my alternator? Or do you think I can run this thing as much as I want with no consequences down the road? Thanks.

[@Casey250]

Depends how close you are to and amps on your alternator I suppose.

[@small.towns.open.spaces]

I like you have had issues seeing the full 800 w charging. I have a 180amp alternator so not sure if that has anything to do with it, but it should be able to put out 60amp with no issues. I as well have a delta 2 Max with the extra battery and at most I get about 530w. I had previously connected up my battery to a 20 amp dc/dc converter and was able to get 430w via the xt-60i port. I'm a little disappointed I'm not getting more. My alternator is capable of outputting 14.8 volts. Idle amperage is 120. When I run without the Ecoflow charger My battery is outputting 14.3 consistently. I tried changing the Alternator Charger to 12v and now I get an over charge error so I have to set it at 13v for the unit to work. I guess I need to call Ecoflow.

I’ve been using the broncos inverter to keep my glacier charged. When I bring my Anker 757 into the vehicle I move that xt60 connector to solar port on the Anker and run a usb-c cable to the glacier.

I have the Delta 2Max and the wave 2 love them both. I wish they would add a remote switch or wire so you can turn it on or off with a switch pod or just a mechanical switch that would easily solve the power drain problem. Also I believe you can use the DC to DC cord to charge the Wave 2's battery....Eco flow sells a kit with it all together-- wave 2, the add on battery and the charger, it would be a shame if they didn't work together. I dont believe you can run the AC and charge at the same time...

The EcoFlow alternator charger is good. Downside: only works with EcoFlow. Expensive. Positive: interesting app features to fine tune the charging. Highest charge rate. Risk: double check your alternator specs. You don’t want to draw too many amps from it. My sailboat only has a 60amp alternator

[@DuaneForrester]

@casey250 - did you hear back from EcoFlow on why the charger wasn’t putting out the full 800 watts the following morning/day? (I went through the comments here looking for that, but didn’t find a post from you about it. Could have missed it.)

[@Casey250]

They said to ground it to the chassis not batter negative. I did that for the final install on the Demonator and it's been charging at 800w no problem.

[@DuaneForrester]

@@Casey250 oh, interesting! Glad I asked. Doing my install tomorrow and the instructions make both suggestions- body or battery. Body it is! Appreciate the help, Casey! Thank you. 🙏🙏

[@jeffs3917]

My guess is that the ground was not the issue, but rather this was: When he first started the next morning, his chassis battery was significantly depleted. If it continued to charge overnight til it got below 12v before shutting off, YES there would be enough juice to start the engine but it WOULD still be WAY below a full charge. So for a while when running the next morning, the alternator would be pumping heavy juice into the chassis battery, and not have enough uumph left to reach 800w on the EcoFlow. Drive for a while and as the chassis battery recovers, and then if alternator is still up to it, the EcoFlow would then get up to 800w. I don't know what level of depletion for the chassis battery is "safe" for repeated use. But as some other comments in here have said, repeatedly depleting the chassis battery to an unsafe level will kill it prematurely. Also, running the alternator to its peak max for extended periods will kill the alternator prematurely. BOTH problems could be eliminated if the EcoFlow unit could be set to allow tenths in the voltage. Somewhere around 12.5 or 12.6 should be just about right. It will vary some with different batteries and systems, and with the same battery as it ages. For this device to work correctly if using that feature, one really needs to be able to change it as needed, and bump it within tenths of a volt.

[@jeffs3917]

@@Casey250 I suspect the problem in that case was not the grounding, but rather how depleted the chassis battery was when you first started the next morning. See what I just said to DuaneForrester. I had FLA House batteries in my RV for a while. Whenever I had over-depleted them during the night, then the next day none of my LFP batteries (including two EcoFlow devices, a Glacier and a River power station) would charge for a while as we drove down the road. The FLA batteries were being replenished, and after an hour or so of driving -- more if we had depleted more of the house batteries capacity -- then it would gradually start adding more charge to the LFP batteries. Just my experience, but it could have been that same situation for you. Especially if now you normally are seeing the 800w again, which you would when your chassis battery is not over-depleted most of the time.

[@rtsrts2317]

I have several EcoFlow devices but have had issues with them. And reporting the issues to EcoFlow was a non-plus situation. I was told to hold the power button in the off position for 15 seconds then restart to see if that resolved the issue. Problem is I rely on this particular unit to power my lift chair and can no longer rely on it as it has quit several times for no reason. I merely disconnected it and will only use it when there is no other source of power. I can no longer have devices connected all the time while the unit is plugged into grid. What a shame. I had high hopes for EcoFlow, however I've been disappointed. When the unit fails, I cannot get out of my lift chair to plug the chair into grid power and am stuck in the chair. I must phone someone to come and make the changes. EcoFlow didn't seem to be helpful or even concerned that their equipment failed. For me, EcoFlow is not a brand I can recommend any longer.

[@ben31tube]

You should be able to use this between battery banks, also!

[@philcadorette1383]

Great video! As a retired mechanic, I see some potential issues. Vehicle alternators are designed to keep the vehicle battery topped up, but can handle some high charge situations for short periods of time. When you hooked up the eco flow battery cables in parallel you essentially now have a dual battery system. The alternator can’t tell the difference between the batteries, thus it will charge the batteries up until fully charged. When this is happening, the vehicle battery is also receiving the high charge thus producing the negative effect of too much heat for the vehicle batteries and alternator. Over the years I have changed dozens of vehicle alternators and batteries due to having one battery being charged up too often , the fix was one alternator and 2 batteries, ouch! Hopefully ecoflow has some sort of setting that would prevent this, otherwise the risk is too high and expensive if you are going to charge through ecoflow from a low state of charge. Can anyone address this ?

[@ozmanfidaar6311]

There are much better DC-DC chargers in the market than what's reviewed here. For example, both Renogy and Victron have chargers with hardwired voltage sensing options--that is, as soon you turn off the engine, the unit automatically turns off. Renogy units even have current limiting and turn-off options when the engine is on. It seems to me, the Ecoflow is a bit behind given this is their first DC-DC charger.

[@bdmenne]

Glad you spoke up. Hope you get more feedback so we can all benefit

[@gregsheridan]

@@ozmanfidaar6311this isn’t a regular DCDC charger. It is 12V to 40-60V so it can charge the Ecoflow. Quite different than a regular DCDC application. Also it is about 65A at 12V output which is higher than any regular DCDC chargers which are normally 25-40A. Renogy has a 60A. You can’t use a regular DCDC without a voltage converter.

[@gregsheridan]

It is potentially an issue to draw this much 65A current continuously from an alternator for several hours. I think that is why most DCDC units are lower output. Even the units get hot and this one is smaller than a Redarc, Renogy, Victron or CTEK however this outputs higher voltage 40/60V and lower current which would help with sizing and heat.

[@christianarias4850]

Is it only compatible w the eco flow units?!

[@Electric_camper]

I'm surprised alternators do such high output directly. Whilst the 12V sockets are mostly 300W max.

[@RCMediaSigns]

Good review however 11 volts is too low for a flooded AGM battery in just a day it will reduce to critical levels. Also it’s not an alternator charger it’s a battery charger , it has no control of the alternator.. Also if you have a stock alternator charging at full 800 watts with your air and lights on is going to take the alternator out in just months.

[@zalllon]

I wish this device came out three months ago as that’s when I bought everything using the Victron DC/DC 12/24 volt converter for my EcoFlow Delta 2 Max

[@Casey250]

You can use them both for 1100w of charging :)

[@Justin-C]

At least the Victron will work with non ecoflow units.. in my opinion, the ecoflow price premium on this is pretty ridiculous considering that all it really brings to the table is higher wattage (~800W vs ~500W) and reverse-charging.

[@lolprice6190]

I cant get mine to work I've had 2 now both seemed to be faulty no output permanent red light and error codes 😢

[@richardweerasinghe3296]

Once you have to install something like this alternator charger you are basically there with a dual battery system. So not quite sure what the main advantage is.

[@PeakyBlinder]

I got one of these and it refuses to charge,

[@frankchan2589]

Is there a video that can teach me how to route the cable from the car battery to inside the vehicle so I can charge my power station while I’m driving?

[@Casey250]

That's going to be so far dependant. If look for a video of routing wiring for maybe a stereo amp for your vehicle. For a jeep I'd go down the frame rail and up the drain plug in the passenger footwell.

[@volleyballDave]

As of the date of my reply, there are now multiple videos with details about this charger, and at least two of them show the routing of the wiring from battery through a grommet in the firewall, under the door frame (down by the carpet) to the back of the vehicle.

[@macairtuber]

Why not just use a regular ol' $150 vehicle inverter - like a 1200 watt and just charge via AC? Most power stations take a higher AC wattage input than solar - like the Delta 2 is 1200 watts AC input vs 500 watts solar and the new ecoflow alternator charger maxes at 800 watts. What am I missing? Sincere question - This lectrical stuff is above my IQ. So wouldn't a 1200 watt DC to AC inverter charge 50% faster than the ecoflow 800 watt alternator charger? Please clarify

[@jasonnoble5090]

Goal Zero makes an alternator charging kit that fast charges also.

[@Big_Mafuta]

This is better value. PECRON 500W Car Charger DC1242-500 for Cars, RVs, Trucks, etc. $149 Not as fast charging as the ecoflow. There a few videos on YT for this. Pity it is not yet available in Australia.

[@gmcinbc5669]

Do you know what the impact on your alternator would be after prolonged use?

[@randythraen216]

Depends on the vehicle and what your charge rate is. If I'm charging the Ecoflow off my alternator at 14v, 300w, that means I'm pulling around ~20amps. If your vehicle has a smaller alternator like mine (05 GMC canyon with 100amp alternator). That means I'm using almost 1/4 the alternators capability. With the increased strain on the alternator, you will experience faster wear and could shorten the lifespan. I plan on upgrading to a 200-300amp to reduce the stress on the alternator and increase reliability.

[@jcar1417]

@@randythraen216I have dual alternator on my power wagon, 400 amps from the factory, nice to have when winching, great option.

[@gmcinbc5669]

Thanks nice to know details like that

[@davidhaymon1708]

So I just bought the Wave 2 with the battery and the alternator charger as a package and the alternator charger doesn’t work with the Wave 2 battery? That’s pretty much false advertising in my book. Once they actually send me the alternator charger it looks like I’ll be sending it all back. I don’t have a Delta and don’t have room in my Jeep for one of I want to take the Wave 2. Without the alternator charger the Wave 2 is not going to work for multi-day trips, which was why I bought the package in the first place. I have a River 2 Pro, but it looks like it won’t charge it either. Pretty crummy EcoFlow!

[@macbeliever]

I would love for Casey to follow up on this and confirm, it does seem really weird that Ecoflow would sell it as a bundle if they don’t work together. They even advertise it as “1 hour of driving gives 5 hours of cooling”. Casey please test this if possible or contact Ecoflow for further explanation. Thanks!

[@crazy-eyewoodguy4489]

I dont believe you have anything to worry about. I think where he got mixed up was trying to "run" direct from the charger. you cant run the AC and charge at the same time👍🏽

[@Casey250]

I'll check it out when I'm back home. I need to see if my wave 2 battery needs a firmware update to recognize it.

[@Baebon6259]

I find it strange that your Jeep battery dies after 2 weeks of not driving...unless something is drawing power from it.

[@billquantrill4960]

My Tacoma does the same thing after I had remote start installed. But, since its usually driven daily I rarely have a problem. All vehicles have a parasitic draw of some sort unless you disconnect the battery.

[@danboutdoors4584]

EcoFlow just needs to have a trigger wire that you connect to a power source that is only on with your cars accessories. That way it will know when the engine is off and stop charging. Most DCDC Chargers do that now….

[@Casey250]

A trigger would be perfect. I wonder what the cat5 remote port is capable of.

[@BackcountryBeta]

vast majority of vehicle alternators (unless HO or dual like on an ambulance, etc) are not designed to charge high cap house batts like this. they're designed to "top-off" your starting battery and maintain the small currents for the vehicle's electrical draw while running. also not at all "normal" for your starter batt to be drained down like yours is; you are greatly reducing the life of you battery when that happens.

[@Stealth_Overlanding]

Question. I have a delta2 and I’m interested in this for my rig is it possible to hook up the delta 2 extension battery and use this in conjunction? I can’t find anything on line. Thanks!

[@Casey250]

You can hook 1 expansion battery and the alternator charge at the same time. The Delta 2 has 2 expansion ports available. If your using 2 expansion batteries, you couldn't use the alternator charger.

[@jaysonjohnston3611]

Any idea why it’s not compatible with the Wave2 batteries?? That would have been my main reason for purchasing this alternator/charger…

[@Casey250]

I dunno. I thought it was suppose to be. Maybe I missed a firmware update.

[@volleyballDave]

It connects to a Delta series power station using the XT90 connector. It cant connect to a River 2 series because they use an XT60 connector. I'm not sure if the Wave2 has a XT90 connector.

[@jmvreest]

Anyone have any pros or cons since this was posted?

[@alfredneuman1179]

I am not happy with my ecoflows - they have had their fair issues that ended in RMAs for me… some simple (non-chinese) battery for around half price hasn’t got any features or app connection but hasn’t broken yet… subjective I know, but objectively happened to me

[@Casey250]

Always appreciate hearing the stories

[@Iamandthatiam]

can this be used with anker?

[@socialbutterfly101]

It would also require telephone service.

[@666wilf]

Do these alternator chargers work on all EcoFlow or just the Delta 2?

[@Casey250]

The Delta 2's with expansion ports.

[@Justin-C]

Cool, but not ~$600 cool - pretty outrageous, actually. This feels like unnecessary proprietary lock-in. The main thing this offers over one of the numerous DC to DC options in the $70-200 range is reverse charging. Victron sells a $130-150 12 to 24V DC to DC converter that can get you 400-500W of charging on a Delta 2.. and it'll work with essentially anything that has a solar charge controller onboard.. at a fraction of the price.

You have to plug the wave into the Delta 2 to run it

[@michaelshin69]

Nice system but my landcruiser's dual system works just fine with less $

[@charlieb3943]

Dual battery is way better because you have a reserve when needed with a power inverter after you drain your Eco system. Don't have to wait

Do you happen to know if it works with a river pro II?

No. Not unless they make some adapter for it.
