5.0 out of 5 stars Excellent Product! Worth every penny.
Reviewed in the United States on April 20, 2024
Bought the ecoflow delta 2 max for power for my vendor tent at live events. Have only tested at home so far but I will be taking it to a 2 day festival next week and I think it will do great. Charges crazy fast through AC outlet. Charging with solar panel is obviously slower charging but it does charge up just fine. AC outlet will charge it with like 1650 watts and gets to 100% in a bit over an hour. With the 220w solar panel I got, I set it to charge from 60% and it said about 11 hours till full, but I also don't think my panel was at an optimal angle because it was only outputting about 150w. Love how the panels fold up into the case, very portable, and for the most part I feel like the case offers some good protection during transport.

Performance is impressive, for what I need it for. I need to run 1 3d printer on display, lights, charging for my phone and other electronics of course.
at 100% charge, I ran 1 of my 3d printers off of it for over 11 hours and the battery was only 60%. I think this setup will work PERFECTLY for a vendor booth. This is going to make my setup really pop.

5.0 out of 5 stars Great Backup Power Station
Reviewed in the United States on July 1, 2023
I bought the Eco-flow Delta 2 Max power station a couple of weeks a go and I am completely satisfied with my purchase. The unit is very well designed and a solid build build. It's very easy to setup and charge. In fact the fast charging feature allows you to fully charge the batteries in under two hours when plugged in to a wall outlet. There is an excellent app that you can download from the Apple App store. The app gives you up to the minute information as to the status of the device. You can see when it's charging and adjust rate. You can also see the wattage of of a connected device drawing down the battery as well as an estimate of how long the battery will last at a given rate. You can monitor the device remotely using the app even when you are out of town. I also like the 10 year battery life of the LFP batteries and the 3,000 charging cycles as compared to other similar devices. The device weighs in at about 50 lbs which is not light but easily manageable.

We have a lot of power outages in my area and my main reason for the purchase was for backup power for our refrigerator and wifi modem and router. I tested it on our Samsung refrigerator and could monitor the discharge rate and time. It worked beautifully and will help us avoid losing a lot of food from our fridge and freezer in the future when there is a power outage.

Overall, this was an excellent purchase. I like the company and the support they provide on their website. I also purchased the solar panels to go with it for times of extended emergency power failures.

I started with the ECOFLOW Delta-2 by a mishap, but it was easily cleared up by their superior customer service. I now am the proud owner of the Delta 2 MAX. I have some photos of the readings from a gloomy/overcast/cloudy day, where I was still pulling some wattage to charge the system (around 35-45 watts) Then some sunny day shots of the panels set up using their built-in stand=works very well, especially since it is actually a built-in stand from the protective/zip up cover/storage for your expandable panels. They fold out easily and set up just as easy.
Make sure to take advantage of the dual surface capabilities! I have pumped out 190+ watts using reflective materials that project the sun's rays unto the back of the panels as well.
With the sun at 10-2 pm, and no reflective materials set up yet, I was cranking out 140-160 watts, as shown in the pics.
I do not remember if I got the 190+ watt shots, but I will check my phone and post if I can find them, if not, I will get some as soon as I drain the MAX and have to charge it back up.
These panels are rated at 220W, and saving you from boring details of specs etc., that equates to around 140-160+- watts during full sun in California.
If you need to charge it fast for a trip, use the wall plug, it CRANKS the watts, I have a shot where its at 1152 wats from the wall outlet in my house.
The max is portable and light for what it pumps out, "quietly". I am around 6' 200lb weight lifter type guy, and it is light for me, I can carry the generator in 1 hand, and the panels in the other, so many of you fellow muscle guys & gals will be able to do the same I'm guessing, otherwise, just make 2 trips or get a buddy.
I also show some shots of it running a dyson vac & washing machine at the same time=EASY for the max.
I ran my fridge with the D-2, so the max will have no problem with the fridge as well.
The customer service is amazing, responsive to you within 24 hrs, sometimes within the same day=few hours even. They are so professional and kind, even fun to speak with. All have been from the Philippines, and I have YET to receive anything less than superior customer service quality from the Philippines, its as if they were born with superior CS skills built in. I am very grateful for their abilities to handle any and all issues I had after my initial purchase, and the follow up is just as high quality. AND, the issues were minor, and few. Mainly my misunderstanding of specs/etc. as I am quickly learning about the solar products. They have been a HUGE help & friends to my new venture into solar power. YES, I said FRIENDS! Think of one of your best friends, and they stand behind their products like a best friend would stand behind you. Why do I mention this? Because I know how I felt about purchasing my first solar generator, the anxiety & plethora of questions in my head. I have been researching for a few Years, and I am 100% glad I chose ECOFLOW, and I have complete confidence to put MY NAME on their customer service and product support.
Bottom line, you CANNOT GO WRONG with ECOFLOW products if all their CS reps are like the ones I spoke with, PLUS their products are performing up to and beyond expectations!
At this point, a few months in to owning the MAX, I am extremely happy, and satisfied with every aspect of their company, how often can any of us say that today?
I will be investing in a whole home system sometime in the near future, and ECOFLOW is at the top of the list.
