Have had this for about a month and a half now, charge is extremely quick when plugged into AC. Charges decently fast when hooked up to solar, I have a combined 720 watt input. So far everything seems to be operating correctly, I did have one issue where it dropped its Wi-Fi connection and I kind of had an issue getting it reestablished. I reached out the service and they gave me some ideas of how to get it to work again, I got it to work again. I do have two extra smart batteries attached to this Delta 2 Max. With everything hooked up it does take quite some time to charge on solar. Which is to be expected though it has to feel quite a lot of power reserve. This will come in handy when the power goes out and I need to maintain critical items in my home. All in all I think it's probably a great product, only time will tell though.

This has been an awesome power station for our off grid camper and work needs. We have used it for our 12v fridge, lights, computers, tools, smoker and microwave. It powered our 12v fridge for over 36 hours and still had 15% power remaining. I definitely would and have already recommended this to others.

I use it mostly to power my Dometic CFX3 95DZ when off the grid. I can get around 2 days, depending upon the outside temperature without using solar to charge the battery. I bought this to replace my Jackery Explorer 1500 and have no regrets. I like the App connectivity and configuration/display options. I don't know if I missed a setting, was outside of bluetooth range, but it would be nice to configure an alert to be notified when you have x% battery remaining. The 20-Amp charging feature is nice, but I'm not sure I have to many 20-Amp outlets to take advantage of it. It will definitely trip a 15-Amp outlet. Another thing I like about it over the Jackery is that it seems to be sized/shaped better for storage and transportation with the handles on the side. The only other thing that is not certain is if the DELTA Max cover is the official cover for the DELTA 2 MAX, since the website doesn't have a specific accessory section for the 2 MAX.

Bought a few months ago. Unfortunately due to family illness did not have time to check it out. Did bring it up to charge when I got it. Now have tried, hooked to a couple of fans and a refrigerator, ranf for about 30 minutes, worked flawlessly. Still had high percentage of charge.

This Delta 2 Max is all you need for all those road trips or at home for any electrical emergency. I am really impressed with this product, but you will say that it is very expensive, and yes it is expensive but when you have it you will say that it is worth it because it is very efficient and durable that it comes with a 5-year warranty, just enough to get more for your money, thanks

Purchased the Delta 2 MAX when it was released, and happy that I did. It has been a great device with the ability to power most all of my needs. My only gripe is, when charging the time to full capacity reads incorrectly. I have to unplug the solar panels, shut the unit off, then turn it back on, and then replug them in for it to read accurately.

I have a cabin on a piece of land I own that doesn't have electricity so I have been searching for something to power my CPAP (Resmed AirSense 11) instead of using a car battery with an inverter. I managed to get 8 days of usage out of the unit with the spare battery. I was using the AC power and did have the heated tube on along with the humidifier. Average usage per day was right at 11hrs. I have yet to see how long it can go using DC power and without the heated tube or humidifier, but I would assume it would go much further than 8 days. Hands down beyond pleased with this unit and the spare battery!

I've been researching this type of product for over a year. The Delta 2 Max has all the features I was looking for. Long battery life, quiet, reasonable weight and good price. Would have bought the Pro, but a little heavier than I wanted. Will use for power outages and not for daily use. I've only had for a few weeks, but am very impressed by the build quality, functionality, quiet operation, and ease of use. Also bought the 160W solar panel. It works quite well even though one panel will take some time to recharge the unit. There are several other charging options which makes this so versatile. It gives me great peace of mind knowing I will be able to use some home devices during a power outage. Will probably add a second battery at some point. Very pleased with my purchase!

We recently used our new Delta 2 Max and an extra batter for a Delta Max on a week long camping trip. We ran all of our electronics including a 5000btu window AC on our tiny camper without any issues whatsoever. We have solar on the camper and were able to utilize the 2 solar inputs. We use one from the panels and the second from the DC outlet in the vehicle. Also we charged when need using a small inverter generator. The gray part is that we could charge completely in under 3 hours and run the AC all day for the dogs when it was hot. Without the Delta 2 Max we would’ve been just needlessly running a generator. Lots of features and happy to use this setup for many more years.

The Delta 2 Max is all you need for all those road trips or at home for any electrical emergency. I am really impressed with this product especially how easy it is to set up, how convenient it is to check the battery status and output through the ecoflow app, and how it can power pretty much anything I plugged into it may it be my portable fridge, full size fridge, fans, iPhone, MacBook, etc. I also like that it goes from 0% to fully charged quicker than most portable generators of this size
