It is useful to charge power centers like the Ecoflow units faster than the typical 100W or so you'd get from a cigarette lighter plug style adapter you find in most vehicles (or RVs).
Ok. Got it.
>you can use this to quick charge using your vehicle/RV charging system
Wait, you've lost me.
>to charge an Ecoflow battery bank.
I'm sorry, I can charge the thing I am trying to charge by using the thing I am trying to charge to charge itself?
Don't have to connect directly to starter battery. But better be sure wherever you connect this to can handle 800W+. I connected this to the battery service terminal under the hood. Starter battery is under the trunk floor in the back. There's a 175A fuse inline to service terminal so more than enough amperage to handle this. The included 16ft cable is 6AWG with 125A fuse. Ring terminals are M8 size.
Normal starter battery voltage is <13V. Once engine starts, alternator ups that voltage to >13V. Once engine shuts off, voltage drops back to <13V. Default setting on this would prevent drawing any power from your battery while engine is off. Once engine starts, this automatically begins charging your power station. Once engine shuts off, this automatically stops drawing power to keep your battery from getting drained. This start/shutoff voltage setting can be customized in the app but default worked for me out of the box.
In case your starter battery is drained and cannot start the car, this can go in reverse and use your power station to charge your starter battery. This is done with just a simple tap in the app.
On EV or certain hybrids with no alternators, this still works (and better IMO). The car uses DC-DC converter to reduce 400/800V traction battery down to operate 12V devices and to charge the starter battery. This is also a DC-DC converter that increases 12V to 60V to charge your power station. This hardly puts strain on the car's DC-DC converter as long as it can handle additional 800W+ load. You can always lower from 800W draw from this in the app by swiping left or right.
This can work on non-EcoFlow power stations via solar input at 60V/500W max, provided you DIY your own cable (supposedly official EF cable is on the way): https://youtube.com/shorts/uVBrNY...I80vRe-bdV

I've read elsewhere that this utilizes the "excess energy" from the alternator of a vehicle as if you're somehow scraping energy that's otherwise unused... that doesn't sound right at all but comments like that in various other places and all the hype makes it misleading.
overall I think this is just something that lets you charge your unit much more quickly when out on the road and you don't have access to an AC outlet that can output high enough... it's not something that helps save money, you're not going to be getting "free" energy from "excess energy" from your alternator or anything like that.

Deal Editor's Notes & Price Research:
I can get the hype if you don't have panels or in a place where you don't have a lot of sun. Way faster to use something this to charge your device then.
Our community has rated this post as helpful. If you agree, why not thank Formless

But for those that need it, it's definitely a useful device and a solid price point for it.

In a pinch, if your vehicle battery was weak or not enough to start, the alternator charger can reverse the flow, and allow the delta to recharge the starter battery.
This thing puts too much stress on the alternator.

Not sure if this will really work without some RPM.

And, from what I saw with this, yes - you'll need to wire this up to go through/around a firewall somewhere on your vehicle
It is as you say, a smart charger. It has some smarts to not charge when the engine isnt on/isnt driving. It is also adjustable in how many watts to charge it at. Mind you most vehicle alternators are 100A or higher nowadays, thus 100A= 1200 watts, more or less.
Could you recharge from your 12V outlet? Yes. Its capped somewhere around 8A at 12V, so less than 100w.
Keep in mind this unit is only compatible with the ones with the ecoflow xt150 connector. Anything else is not compatible. However this keeps your solar/dc xt150 ports free.

You use an EcoFlow battery bank.
You want to charge your EcoFlow Battery bank faster than a 110v hookup.
Think of this as a second alternator making the electricity to power your battery bank but faster than if you were just using 12v->110v inverter.
All it is really doing is boosting the 12V@65A to something like 60V@12A. (rough numbers, I don't know for sure, but the process is correct).
This isn't inverting anything, its boosting.
This thing puts too much stress on the alternator.
If you have a modern vehicle with power lift gates, infotainment, heated seats, etc, you will most likely have a 150amp or higher alternator, which can push above 1500W easily.
Most of that is used in the very beginning after starting up to replenish the battery.
the inputs are adjustable. So you don't have to do the full 800 if you don't want to.
This thing puts too much stress on the alternator.
Electronics will go when pushed too hard when hot. Brushes will wear out regardless of load. Sometimes, failure is just due to age. Very few alternators die within the first 5 years of ownership. Alternators for HD vehicles run with no issues like emergency vehicles, and they have constant load.

But yes, if you're using this on a small van, it could put too much load on your alternator.
