Style: Delta 2 Max+800W Alternator Charger
Used this battery to battery charger on multiple long-distance trips to help power my Ecoflow Delta Max portable power station and it worked well. I did turn down the output of 800 watts to 400 watts, on the Ecoflow app, in order to protect my vehicle.

it's a great product and does as described. I installed the alternator charger and it works perfectly. The Delta 2 Max is a little heavy but has the power that I needed. My only feedback is that the main outlets are on the back of the unit which can a bit challenging without moving it in and out of the storage spot. it would have been great to swap them with the usb ports for better usability. it's a nit but something to think about.

Stay away from the brand highly advertised by Hobo Tech he is good product is less to be desired it works 1 and a half years or so mine lasted from purchase 2024 to Dec sometime 2025 for what you pay other brands have higher support like Anker and offer all but what I needed which was the alternator charger fans stop working after this time frame plugged into AC it's like jump staring a car after on AC you plug and unplug then plug in (listen this is 2024 to 2026 we should be past this with given technology. Steer clear of Eco flow if you need reliable service in emergency situations

Love my Ecoflow Delta 2 Max, with its LFP chemistry, and the Alternator Charger that I got with it as a package. Both have been nstalled in my self-built camper van for about 100 days, and have performed flawlessly.

The Alternator Charger worked for about 3 to 4 weeks where it would push high wattage consistently. My alternator in my Buick Enclave seems to work just fine. The Alternator Charger started to not work. When I first turn on the car it kicks on at about 450-550 watts. It then slows down to the point where it fluctuates between 0 - 20 watts going into the DELTA 2 Max. The voltage displayed on my car will be around 14-14.5, but the app will say 7 or 8 simultaneously, randomly. If I turn off the process it will start again the same way. It now takes very long time to charge. Very, very disappointing.

This is a simple to install, clean looking, and excellent product! Charge up to 800w for your EcoFlow Delta units. It also has reverse charging to charge up your starter or house battery. You can put it into maintenance mode to keep your starter battery topped up from your Delta units as well. Great for overlanding, rv’ing, camping, etc.
