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

Long answer is to consider a couple of things...
1. This does not charge your Tesla directly. This would charge your power station which in turn charges your Tesla. Keep in mind this could output 800W max so while your power station may be able to charge your Tesla at higher rate, you could only sustain 800W without depleting your power station battery. This means getting ~3 miles of range on your Tesla per hour of towing. 6 hours of towing would net you ~18 miles of range which is not nothing, but you could stop by a Supercharger and get more range than that in a couple of minutes for a bathroom break. I understand using Supercharger may be a pain while towing, but Tesla tweeted expanding pull through Superchargers 3 days ago.
2. EcoFlow power stations may not work with your portable Tesla charger without bonding ground and neutral. I tested my BMW Level 1 charger on my Delta 2 and did not work. I didn't need it to work so did not test with a ground-neutral bonding adapter. But you would most likely need to use such adapter to charge your Tesla and be aware of any potential shock/electrocution risks associated with such workaround.

As long as you have a ~20A or greater source available (e.g. 7-way trailer plug, or dedicated 10AWG cable/ 20A fuse direct to battery) you can make up a lead with a XT60i plug on the end which will enable 'solar' mode on your River Pro. This will allow it to charge at ~15A, halving the time to charge the unit. This is what I plan to do for mine.
Honestly, it seems designed for non technical people. All packaged batteries have a bms so I don't understand why this is >$40. Lots of similar products at around $100.
I would recommend one except I am reluctant to give advice that leads innocents to draw a constant 800w from a stock alternator. That would be really dumb.
You still need a charge controller- and good charge controllers that can handle 60A or higher (like the victron or orion is way more than 200).
Those also don't have the ability to maintain a set voltage level of the main battery, if your somehow using it for something else like heavy lighting equipment or the ability to charge the starter battery should you find yourself with a dead/low battery.
The other large factor is that you didn't include wiring. 12V DC to DC capable of 60A require equally thick wiring, whereas higher voltage decreases the wiring gauge.
This price includes basic wiring. There's probably 50-75 dollars in wiring should you pickup the wiring lengths and gauges.
