Works as described by Ecoflow.
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.

DC to DC alternator Charger
100% Easy to install I wish my Eco flow Delta 2 power supply had 90° cable connectors for connection to extra Battery.

You truly wont regret this purchase.
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.

Very Happy!
Game changer! Charged my Delta Pro in about 4 hours. Make sure it is compatible with your EcoFlow product. It is not compatible with my Delta Mini.
