## Description

desertcart.com: 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 : Automotive

Review: Ecoflow is top notch - Excellent product, keeps my batteries charged in no time. Heavy hardware, thick wires, this unit is larger then you think from the pictures. Install is straight forward, plug and play. The reverse charge is a nice bonus to keep the trucks batteries maintained when needed.
Review: HOW TO INSTALL, AND THE ADAPTOR YOU WILL NEED - 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 desertcart. 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.

## Features

It capitalizes on surplus alternator energy, enabling you to power essential devices like phones, coffee makers, and lights while on the move. *Note: Alternator capacity varies by vehicle - Please verify with your manual (or the alternator's manual) that the alternator's output supports the alternator charger's maximum power draw for safe operation.

### ⭐⭐⭐⭐⭐ Easy DIY installation.
*by J***G on June 21, 2025*

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.
