EF ECOFLOW 800W Alternator Charger, 3-in-1 Fast DC-DC Charger for Portable Power Stations, Car Battery Charger & Jump Starter 8× Faster Than Cigarette Chargers, Charges 1kWh in 1.3 hr | Car Battery Charger & Jump Starter 8× Faster Than Cigarette Chargers, Charges 1kWh in 1.3 hr for Portable Power Stations

Received everything in the box I needed to hook up. Followed instructions, with wifi, used the app to connect my delta 2 max and software update before hooking anything up. Made sure the power supply was on first. Then hooked up the charger. Began working right away. I then did the software update to the charger. I also plugged in the ac charger to the cigarette lighter when running the vehicle for another 100 watts charging capacity. It automatically detects charge going to the battery (when the vehicle turns on), then starts charging. As for my 2024 delta 2 max it's compatible. I have an upgraded alternator in storage. So I can actually use the full capacity of charge.

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.

Once up and going, it is worth 5 stars. Getting there was a pain! I have a Delta Pro 3.6kWh system and wanted to connect the alternator charger to it. However, the documentation was not clear. Then after much googling, I learned I needed to buy an adapter (ummm, it should come with it). You need the "smart generator adaptor compatible with Delta Pro" and can find several here on Amazon. I just bought the cheapest and it worked. The cable from the battery plugs into the alternator charger. Install it with the icon facing up and match the icon on the cable to the icon on the alternator charger. You can also tell which one because the cable from the battery does NOT have the small communications pins in the center. Then take the cable that came with the alternator charger and plug one side into the alternator charger (to the connector that HAS the small communication pins in the center and be careful to do it properly). The other end of this cable plugs into the adaptor mentioned above, and then that adaptor plugs into the battery port (I used battery port 1) on the back of the Delta Pro. It can only plug in one way, and the cover on the Delta Pro is just rubber and hinges down out of the way.

So far it works well, couple caveats to ownership. The device requires WiFi to setup/update. I get the need for updates, but should be able to control/monitor the device without WiFi. Second caveat, depending on the vehicle, it can be very difficult to install. I decided to have a professional do it and it cost over $500, due to the thickness of the cable and lack of accessible ports through the firewall. After the install everything works well and is able to produce over 700 watts of power.

As mentiontioned above, you need the generator adapter to use with the Delta Pro. Also, and this is the bing ding for me, I have to turn on the charger EACH time I get in my Jeep. When I wrote to Ecoflow TS, they suggested turning it off each time as well. The fact that I have to do that and there's not an option for a relay or accessory triggered input baffles me. As of now, I am waiting on a response from Ecoflow, as to whether a relay will even work, as it appears to turn off each time and I'm not sure if it will even recognize the relay power when it turns on. Also, right now, I don't turn it off and it turns off on it's on. When I first turn it off, it goes into a standby mode and the light flashes green. When I switch it to battery maintenance mode on the app, it shows the charger drawing 100w, which I also find crazy. 3 stars only because it delivers 800w.

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.

Good

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.

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
