Style: 800W Alternator Charger
Installed into my 2004 Silverado 1500, and I get full 800 watts in. Install was easy. The product is very robust.

This is an amazing product. I run a HCalory 8Kw Diesel heater for 10 hours using approx 50% of my EF Delta 3 battery. Connecting the battery to the 800W Alternator Charger recharges the battery from 45% to 100% in about 50 minutes. I basically let the truck run for 50 minutes at idle, or when I am off-roading and the battery is at 100%. This allows me to extend my overland time. Love it and recommend it.

Installed in my Transit 150 van. Easy to do, works as it should. Max charging speed I observed was over 1200w, but I use it at 400w which is fast enough for me and keeps it from getting too hot.

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.

BEWARE This alternator charging unit bricked my vehicle. It caused an over voltage through my vehicles electrical system causing damage to multiple electrical components. Ive now spent more on parts (not including another $1100 in labor) than I did on this battery. Im livid and extremely disappointed. Seller will not refund. My van has been in the shop a total of 8 days now for this problem. Avoid this unit at all costs if you want your car to remain in working order. It was installed in to a 2013 chevy express. BEWARE

Love this unit, charges my battery while driving controlled by my phone and app works great. Very solid in build and design. The only thing I would recommend is to have a high out put alternator or upgrade if you don't.
