Good to note. Thanks!

Should work with the Delta 2, Delta 2 Max, Delta Pro and Wave 2 battery. I'll edit the original post.

You're putting a lot of strain on your alternator and wear out the brushes faster.

Sure, if it was used at full power all the time. You can actually set the charge rate through the app if you don't need to quick charge.

I opted for the pecron 500w car charger instead for less than half the price. Its only 500w vs 800w for the ecoflow but I drive at least 10 hours a day so that's more than enough to fully charge my unit and its much cheaper.

Only for specific models. My Delta 2 Max I can't adjust the speed in the app.

So this is a boost converter that boosts 12V to like 48V so it can charge several times faster, correct? Does it somehow sense if the alternator is on or off to prevent draining the 12v car battery? Anyone use this on an EV yet that has a High voltage to 12v dc converter instead of an alternator?

I've been wanting something I can pair with me EcoFlo so during power outages I can charge the Ecoflo off my EV and power fridge, computers, lights for like weeks if needed.

That one looks interesting, as it has a pot for adjusting the start voltage, to prevent it from draining the 12v battery. Wondering if the Ecoflow has adjustable voltage like this.

Also, what do these output, 48v? Wondering if it can be used with say another kind of battery...

I believe these units work based on sensing an 'engine/alternator on' voltage level e.g. ~13.6V. Other units can be wired up to sense 'accessory power on' and only power on under that condition, like the Victron 12-24V 20A converter I got to serve the purpose of getting ~400W into my Delta 2 from my car.

Nice (and somewhat tempting thing) about these is that they have reverse charging too, which means they can help manage your battery if you've got a weak one on its way out.

The reverse charging feature is what caught my attention, it's one of those things that's nice to have and not need until you do.

Can't speak to the operation yet, as mine is still in the box.

Oh those are cool. Wait so are you saying the Victron has reverse charging or the Ecoflow or what are you saying?

Secondly, it looks like the Victron can adjust up to 30v. So 15A * 30v = 450W input is not bad.... Certainly enough to keep a fridge going that uses 100-200 watt hours per hour.

So with the Victron the "accessory power on", I'm assuming you would tap into a fuse or some other signal wire that only receives power when the car is on, and then that would internally switch the boost converter on so it can draw power from the battery/alternator, is that right?

I did as well. Much better bargain and works with any PV input.

Ecoflow's has the reverse charging, not the Victron.

And yes, you can use an 'add a circuit' fuse tap set to say "Victron, turn on" - something like this depending on your fuse box type: https://www.amazon.com/gp/product/B07T8LRSH7 (it doesn't draw power through this, this is just the "on" signal)

It's pretty easy to stick one under your front seat for use either in my back seat or trunk/back - worst part is getting the main 4 or 6 awg wire through the firewall into the vehicle.
