EF ECOFLOW 800W Alternator Charger, 3-in-1 Fast DC-DC Charger

Decided to buy this EcoFlow 800W alternator changer, since my AC outlet in the truck bed does not provide a pure sine wave required to charge my EcoFlow batteries while traveling. It was not too difficult to install once I decided on best location. The only issue was once I turned the unit on, the power light turned from green to red, meaning there was an issue. Crap, did I mess up the wiring or something? No, just a simple firmware update was needed, which I already had the Ecoflow app from my other devices, added this alternator charger to the app, updated the firmware, and ready to charge. It started charging to 500W right away, and after a few minutes got to charging at 800W. So works very well and as intended. UPDATED - EcoFlow did finally come through providing the cable puller I was missing, so changed the review to 5 stars. It took a while, but they did get it done. Utilized while off grid this past week, and very efficient charging while traveling, very happy with this upgrade!

Had to return and list money in that transaction, not a simple return. I couldn’t use the plug with my Delta Pro 3 we have had a while. Am very satisfied with the 500W version. That plug is compatible.

I purchased this to charge my EcoFlow Delta 3 and EcoFlow Glacier fridge in the cargo area of my Land Cruiser. The charging speed while driving has been phenomenal—within 45 minutes to an hour, both devices are usually sitting at 99%. I had a pro shop do a custom install to wire it in seamlessly, so it looks super clean and works like a charm. See my photos of the setup and build. Before this, I was using the Land Cruiser’s factory 240W outlet, which worked but took several hours to top everything off. Stepping up to 800W DC-DC charging is a night-and-day difference and completely worth the money. The only caveat to be aware of: despite the heavy-duty shielding on the wiring, the unit emits enough RF noise/frequency interference to occasionally trick my Land Cruiser into thinking the key fob isn't inside the vehicle. It might be partly due to Toyota's internal antenna placement, but it's definitely something to keep in mind if you drive a newer SUV. Still, I'm extremely happy with the performance

It works well. Using only a 12 volt or 24 volt lifepo4 battery. Getting 500 watts with the “prime days deal included” CT60i cord. Issue: I have the Delta Max Plus, and the included xt 150 cord does not work for me at all. Because the adapter (smart generator adapter) cannot be found. It is apparently vaporware on the EcoFlow site. As is the custom cable for the Alternator charger. As I have the DM3plus, I am small potatoes I know, but to not stock this when it is needdd for connection with the Delta Pro 3 and the Smart generator is astonishing and highly dissapointing. So my rating is for function. The Alternator works great. BTW, the XT60i cord charges my River Pro 2 and River 3 plus at 220 watts. So thank god I hit the deal for the alternator charger with the XT 60i included, or it would be collecting dust.

Ship time was sooner than expected. Product is great quality and preforms as advertised. Using with a Ecoflow Delta 3 Plus. I think the cable to vehicle battery should be a 4 awg instead of the 6 awg supplied. If you will need more cable than what is supplied, I suggest you evaluate your situation using a DC Voltage Drop Calculator to find a proper guage to use. There are many of these calculators on the internet.

This product does not work with the Ecoflow Delta Pro as advertised. When I tried to connect them, I discovered there is no port on the Delta Pro. You actually need a separate $70 adapter — something never mentioned until after purchase. I attempted to buy the adapter directly from Ecoflow, but my orders kept getting mysteriously canceled. Customer support offered no real help beyond “try a different credit card.” Even when my wife tried ordering with a different account, the order was canceled again. I had my wife order the adapter on a different device and credit card and the same thing. Now I just I received an automated emails saying the “trouble report” was closed. The result: I’m stuck with a Delta Pro I cannot charge and an expensive alternator charger that’s useless. Between misleading advertising and the worst customer support I’ve ever experienced, I strongly recommend choosing a different manufacturer if you value transparency and meaningful support.

Out of the box first impressions: Unit is a little larger than I anticipated/visualized but I can make it fit. Did a dry-fit installation this afternoon. From start to commissioning was less than 2 hours. Now I still have to dress in the cable on the inside of the vehicle, but getting through the firewall of my Dodge Grand Caravan using an existing grommet was very easy thanks to the very flexible and slightly slippery cable loom. One of the easiest cable pulls this old cable guy has ever done. Just use a small stiff wire like solid ground or even a coat hanger and plenty of tape to push through. Connections to the battery were equally simple, the in-line fuse block is small enough to tuck in anywhere and I found a good spot next to the battery to route directly into the driver's side footwell. From there it was simple to run along the rocker panels to the back where I have my Ecoflow Delta Pro battery installed. I mounted the unit inside a homemade storage box sized to fit in the stow-and-go well with the Delta Pro right next to the box. The cable that runs from the alternator charger to the battery is fairly short but long enough for my installation. That may change as the build evolves. Commissioning was easy and straightforward. Starting the vehicle brought the charger online. As soon as I opened up the Ecoflow App it detected a new device, figured out what it is and right away began charging the Delta Pro! Of course nothing was set up so it jumped to the default 800 Watts current. I had to quickly reduce the max charge current to 25 Amps because I don't want to overload my alternator (I plan on upgrading to a heavy duty alternator soon). 25 A is still pumping in 350 Watts @ 14 volts input so plenty of power. In fact I will probably leave the max current between 25 and 40 A even with an upgraded alternator just to keep from pushing the batteries too hard, because slower charging is still better for the life of the batteries anyway. This minivan build is one of those things that just happens. I'm using a lot of parts and ideas I used for car camping in my Cherokee, and adding on a few like this. I like that the installation was so simple after working with more complicated setups that required a lot of different components that take up a lot of wall space. This was literally two cables and two boxes, one of which takes a fraction of the space of more complicated setups.

I use this to expand my Delta 2 Max battery capacity, I don't own a car to install this in. I didn't want to pay $800 for another 2000 watts if I can buy a 12v 300ah (3600 watt) LiFePo4 battery for less than $800. Not as convenient as the extra battery, but it works if you're willing to do the research. I know theirs a way to hook a battery directly to the expansion port, but I'm no careful genius to do that work. Even so, I don't know if it can charge the battery as well as discharge it. Granted the cost of this and a big LiFePo4 battery makes it equal if not more to the extra battery, but its more expandable. If I want more capacity than now, I can just buy another battery and hook it up to the system. I just don't like how it's mainly app reliant. No buttons to control the charger directly, only to turn it off. 3 stars mostly because App reliant, otherwise I like this as a battery expander.

Melhor solução para overland. Delta 3 + painel 160W e o carregador formam um conjunto perfeito para uma autonomia de pelo menos 1 semana.

Ótimo produto, a única falha é a ecoflow não informar que para ligar na Delta Pro tem que comprar um adaptador
