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

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.

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 had been eyeing ecoflow products for a while and when everything went on sale for Prime Day I decided to finally give it a shot. My plan is to install this combination in my ‘03 4Runner along with some panels on the roof once I have a roof rack installed. The idea is to essentially turn my 4Runner into an off grid dwelling so this will be powering a diesel heater and some electronics during long overlanding adventures. So far though I have just been using it at home to charge electronics and stuff so I can get a feel for how long it will run. I am very impressed with the build quality of this thing, it looks and feels solid and is extremely quiet when charging AC from the wall and powering DC via USB ports though I suppose that’s an easy load for this thing. The app is great and the ability to track power use over time has allowed me to experiment at home to get a feel for things which is a big plus. It’s about the size I had imagined it would be not super small but also not super large - it is heavy but it’s a battery so that’s basically expected. I can’t wait to get this installed along with my alternator charger but I will have to limit charging speed at first because you pretty much shouldn’t use 800W charging off nearly any stock alternator; you should get a high output alternator for that and that’s my next purchase!

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.

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.

My parents are on a road trip with their grandchildren. One of my grand child really loves milk so we use an ecoflow power bank to power our milk warmer. I decided to get this alternator charger to allow my parents to keep the powerbank charged on the road! Installation was fairly easy! My dad drives a Camry and it wasn’t too hard to route it through all the compartments and run the cables to the trunk. It definitely was long enough for the Camry! Now they are on the road and it seems like the ecoflow power bank is constantly topped up with zero issues! Bonus! My kids loved playing with the box!

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