Review: Excellent - Excellent piece of kit, charges very quick Can definitely recommend, so simple to install also
Review: Do your homework first!! - I have a camper van and installed the Ecoflow charger myself. It’s easy to fit and use and very functional for its intended use. It comes on immediately once I start the van engine. I have a Delta2 Max and it charges very quickly whilst I drive. But whilst it says a maximum of 800w charging capacity I have dialled mine down in the app to a more modest 400w, so as not to overload the alternator. It can be set at what you want up to 800w but the suggestions on some YouTube channels are not to run it at full capacity in order to protect the alternator, unless of course you have upgraded your actual vehicles Alternator to a higher spec. I haven’t yet but will do in the near future. (This itself can be done either yourself or a vehicle mechanic).. . All the dialling down does is increase the charging time, but if you’re on a long journey it won’t matter. It will of course switch off once your Ecoflow battery pack is fully charged. It appears to be well built, although the “on” button is tiny and sits flush with the case making it perhaps a little difficult for someone with sausage fingers. Its weight comes in at a modest 2.2kg. All in all I’d say do your homework” and you will be able to make good use of the Ecoflow Alternators intended purpose.

### ⭐⭐⭐⭐⭐ Quality product
*by A***S on 11 December 2025*

I went for the 800 just because you can charge your vehicle battery if it runs flat plus you can set how much power you want to receive from your alternator so for me it’s a win win
