Review: Easy install. Worked as intended. - Received everything in the box I needed to hook up. Followed instructions, with wifi, used the app to connect my delta 2 max and software update before hooking anything up. Made sure the power supply was on first. Then hooked up the charger. Began working right away. I then did the software update to the charger. I also plugged in the ac charger to the cigarette lighter when running the vehicle for another 100 watts charging capacity. It automatically detects charge going to the battery (when the vehicle turns on), then starts charging. As for my 2024 delta 2 max it's compatible. I have an upgraded alternator in storage. So I can actually use the full capacity of charge.
Review: HOW TO INSTALL, AND THE ADAPTOR YOU WILL NEED - Once up and going, it is worth 5 stars. Getting there was a pain! I have a Delta Pro 3.6kWh system and wanted to connect the alternator charger to it. However, the documentation was not clear. Then after much googling, I learned I needed to buy an adapter (ummm, it should come with it). You need the "smart generator adaptor compatible with Delta Pro" and can find several here on desertcart. I just bought the cheapest and it worked. The cable from the battery plugs into the alternator charger. Install it with the icon facing up and match the icon on the cable to the icon on the alternator charger. You can also tell which one because the cable from the battery does NOT have the small communications pins in the center. Then take the cable that came with the alternator charger and plug one side into the alternator charger (to the connector that HAS the small communication pins in the center and be careful to do it properly). The other end of this cable plugs into the adaptor mentioned above, and then that adaptor plugs into the battery port (I used battery port 1) on the back of the Delta Pro. It can only plug in one way, and the cover on the Delta Pro is just rubber and hinges down out of the way.

### ⭐⭐⭐⭐⭐ HOW TO INSTALL, AND THE ADAPTOR YOU WILL NEED

### ⭐⭐⭐⭐⭐ Pay attention to cable to vehicle battery length
*by R***M on May 11, 2026*

Ship time was sooner than expected. Product is great quality and preforms as advertised. Using with a Ecoflow Delta 3 Plus. I think the cable to vehicle battery should be a 4 awg instead of the 6 awg supplied. If you will need more cable than what is supplied, I suggest you evaluate your situation using a DC Voltage Drop Calculator to find a proper guage to use. There are many of these calculators on the internet.
