The panel works well and so does the tilting stand, so long as the angle isn't too large. Some sort of a velcro mechanism might be helpful to prevent slipping out when windy. I'd also like to see the panel carry case include a large external zipper pocket that could be used for cables and such. As it is I have to transport my River, this solar panel, and then another carry case with cables and adapters. Just a thought to consider.

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.

I have had a Delta 2 for about a year and when the Delta 2 Max came out I decided to pick one up with the 2 110 watt solar panels. I love the information that the display on all of the Eco Flow power stations provides. It’s extremely useful to understand the wattage used by various appliances. I was surprised at how much quieter the Delta 2 Max fans were compared to the Delta 2. The fan noise is not a big deal to me but it was nicer to have them so much quieter. The one concern I have is either the capacity of the batteries or the power used by the inverter. I have plugged in a 100 watt light bulb into the fully charged unit. The display shows about 95 watts used but only 16 hours of run time. The actual time was that or even a little less. That would seem to indicate that the batteries don’t have their full capacity or the inverter is using about 20% of the power. I have not yet contacted customer service about this issue. Overall Eco Flow products have revolutionized backup power for me. The capability of having power with only using a generator to recharge the batteries is great. This is especially true considering the short recharge times of the Eco Flow batteries.

I haven’t had the delta 2 Max for very long so my review won’t be as in-depth as I would normally do. I bought this unit to run my 1000w microwave during nighttime (when my household solar is not active) plus as a battery backup in case of power outages. It runs the microwave with ease and I have no doubt it will run my pellet stove for quite some time if needed. I’ve charged it both off household electricity and solar panels with no issues. My one real complaint is, being this large of a unit, I would think that most people will use it for AC power (I could be wrong). But, the main power button, as well as the screen are on the opposite end from the AC and charging sides. However, if you are charging a phone, hey, you can watch the wattages output, the time it can hold at the power drawn and other info from that same end. It’s a minor quibble, but irritates me. Another irritation (and they all seems to do it), is to have a black package with dark gray writing. I can’t see that with a flashlight and readers. If there were more of a contrast between the colors, I’d have a fighting chance. But again, all 3 of my battery stations, from 3 different makers, are like that. I rated as 4 stars instead of 5 because I haven't had this long and they are sort of expensive. I haven't found any flaws yet.

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!

Works amazing and does 99% of what I ask of it in the form factor I need it, but the lack of 30 amp outlet and 24v car charger output are shortfalls I'd like to see resolved in a future product update. Moving this thing around also isn't the easiest thing. I can carry it one handed for a trip to the car, but anything beyond that, (or any use case that would drain the battery in one sitting) and I find myself highly unmotivated to use it. For now, it is the perfect backup power supply to my fridge and deep freezers. I bought this for electricity during emergency situations and it will definitely do the job!

I just purchased the EcoFlow Delta 2 Max along with the 220W BiFacial Solar panel and took it to our National event for R/C Racing in Rome, NY this past weekend. Me and my buddy charged our 2S and 4S batteries at 10Amps throughout the 4 day event and only required to use A/C power to charge the unit 1 time (due to cloudy day) over the 4 day event. The Delta 2 Max kept up with 2 separate chargers, soldering irons, and phone charging each day! Plus it was quiet and sat on our table. Super pleased with this product!

I own 6 of these panels now. The are the most cost effective way to use solar to charge the River series and the Delta 2 and Delta 2 Max. by combining two or more you can get close to max charging on the aforementioned products. they are small and lightweight and, for me at least, setup is quick and easy. I just lay them on any flat surface, including the ground, and they just work! I have gotten 95 watts out of mine, but I am at a low latitude. Your mileage will vary! If you shop the Ecoflow sales and/or use ecocredits these are the cheapest way to power your systems.They are also just as easy to take down. I highly recommend these panels.

The Ecoflow Delta2 Max is the answer to what I have been wishing for. It is relatively light, it can be used in the house, can be charged with solar panels and the power output is phenomenal. After going through having had an attack on our local power station and being without electric for 10 days, I now have a peace of mind going into hurricane season that I can power my refrigator and freezer plus a few other things.

I bought the new Delta Max 2 last week 7/11/2023, and it is incredible it is running my lights, internet connection, security cameras, induction stove, hair dryer, it will run my window unit ac refrigerator pretty much anything you throw at it. I have five 100 watt solar panels right now I will be getting five more to keep it charged up while I am working. It charges up extremely fast with the AC outlet. I've been watching Eco flow when they first came out when they came out with Delta Max 2 I just had to get it. So if you're thinking about buying one this would be the one to get thanks for everything guys!
