EF EcoFlow 800W Alternator Charger, 3-in-1 Fast DC-DC Charger for Portable Power Stations, Vehicle Battery Maintainer & Jump Starter 8× Faster Than Cigarette Chargers Easy Install Charges 1kWh in 78 m

I haven't fully fitted these yet but did do an initial test which was very good and very easy to connect. I got the full 800w at anything above tick over. I believe it will be a game changer in my campervan. The build quality seems very good and the app is very easy to use. The sleek appearance is pleasing to the eye and the multi functionality will be very useful I'm sure.

Well, easy enough to hook upto the battery.To start with it wouldn't register on the app. I tried to update firmware via the app but it wouldn't allow me to. A email to EcoFlow & the following day a firmware update was available for the Delta Flow & the Alternator charger. After this was installed everything connected & now with the engine running on idle I get 800w input.Let's hope this is well made & lasts long, I will update here if any failures.

Amazing bit of kit

Ordered and delivered on timein fact it came days early. It's a sturdy bit of kit and comes with all the cables required. This allowed me to connect from my van battery to the charger then to my ecoflow delta 2 power battery. It was fairly easy to install and now charges my power battery when I'm driving. Because it does this I can charge phones, run lights and other electrical items like kettles etc in my converted ( camper) van.

Just does what it says on the tin ripped out my old lead acid split charger to this and fitted the delta and it's transformed use ability of the camper I kept the solar and 12v lead acid to run the 12v devices.

I was going to buy an extra extension battery but then I saw a YouTube video about this product. It is amazing. Quite simple to set up and saves a load of cost. When the battery gets low it will charge to the required percentage and off you go again. I also have solar panels but this is very convenient. You will need the latest software on your delta 2 to get it to work but that is a simple firmware update. Great product.

Works, however it regularly dissconects from wifi/bluetooth, and gets very hot.The connectivity issues could be my phone, but surely it should not get quite as hot as it does.I'm still happy with it, but I think you need to be aware of where you locate it in your vehicle, as in plenty of air, and not near anything heat sensitive.

5 star product for your ecoflow would not be with out now.
