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.

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!!!!!!!

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.

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.

Sure beats the other solutions

I used solar panels, charge controllers, AGM batteries, and inverters for YEARS when I built out another camper. I was always searching for direct sun to 'refill' my batteries. I was such a pain—a real distraction to my travels. Now, I use an Ecoflow battery generator and their 800-watt charger. Today, I installed the charger. It was very easy compared to all the old components. So, I only need to take a short drive to charge my battery generator fully. My battery generator and charger are both connected to Ecoflow's app. I can watch the progress of charging and discharging. The app is very professional and provides way more information than I need. But it's nice. The battery generator eliminates the need for solar panels, a charge controller, and an inverter. The batteries in the generator are much better quality than the old AGM batteries. I'm so happy to have made the switch. I would recommend their products 100%; I was lucky to have purchased them during Prime Days and saved a considerable amount. They provide quality products. I'm a happy camper without thinking about the charge of my batteries. Life is good.

Delta II Max w/Smart Battery and 400W Solar Panels

I received everything and it all works great. I spent a lot of time researching different brands, options, performance, YouTube videos, etc. and I am very happy with EcoFlow. The only complaint I have is that the Delta II Max does NOT have wheels. EcoFlow sent me a canvas wagon where you can fit the generator inside but you cannot add the Smart Battery with it.
