Excessive standby power consumption
The standby power consumption is very disappointing. Just having the DC on with no load apparently takes 10w! Otherwise I like the product.

Delta 2 + 800w Alternator Charger
I purchased this combination about a year ago and feel like I need to write a review after using these products. Prior to upgrading to this setup; I ran two Jackery (250w and 1000w) units for my power needs while camping. Switching to the Delta 2 setup minimized the amount of equipment I needed. It also provided plenty of power to run my fridge and charge any other electronics I needed charging. However, this is not the reason that prompted a review. The Delta 2 with the 800w Alternator Charger earned its worth when it got me out of an otherwise expensive situation. I was about an hour away from home running trails when I happen to damage my alternator. Because of this; I was slowly draining my battery and feared I’d have to pay for a costly tow. I had happened to leave my Delta 2 in the truck that weekend and it came in clutch. It was fully charged due to it being hooked up to the Alternator Charger. I was able to reverse the charge and run the truck off the Delta 2 for an hour until I made it home. I charged the Delta 2 every night to be able to drive to work and back until I was able to get the alternator replaced. Needless to say, the Delta + 800w Alternator Charger earned its worth. I highly recommend this setup to the point that I don’t need to run a dual battery setup since I have this to rely on. If you ask me, this combination is worth the money if you spend any time off grid or off the beaten path.

Wave 3 and Delta Max 2 purchase
Bought the Wave 3 and Delta Max 2 very impressed with the quality of the product. We had a bit of a snag with logistics. So I reached out to EcoFlow and within a couple of hours the issue was resolved. The product was delivered the next morning. Should make for a great addition to the family camping trip this weekend!!!! 5 Stars!!!!!!!

Definitely as advertised. Would recommend.
Received a split order on Thursday and Friday. Started testing today (Saturday). Insanely easy set-up. App works well. App includes a very detailed user manual that offers great hints for optimizing the system. Solar panels work well, even producing credible energy output under non-ideal conditions. Does everything I want it to so far, although I’d love some more length to the cables connecting the panels to the battery.

Extreme power with every possibility
This is my second unit, the first one I gave to my son in need. I have been using to power our 35′ while charging through EcoFlow 90 alternator generator connected to 2 Battleborn LIFe4 batteries charging with 800 watt solar panels in pass through mode. Loving the freedom to travel on our own power.

More ports for options to charge and to enjoy more
What are you waiting for, buy this now, double tx60 ports, meaning 1000 solar panels rating, car alternator charger up to 800 watts, stack additional batteries.
