  • Amazing Product, Even Better Support!
Style: DELTA 2 Max+220W Solar Panel
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. ... show more

  • Perfect for a variety of uses!
Style: DELTA 2 Max+400W Solar Panel
So, two parts: 1: The Echo Flow Delta 2 Max I had initially just gotten this to be the power station for my camp setup. But thinking about it, it's a lot more than that. It can be used to recharge my RC batteries while at the RC field. It can power appliances at home. If you need to power a light system for the backyard. Power a projector and laptop while out at the park. It's portable power... This is 50 lbs. It is heavy. But the handles are sturdy. Packing it into my SUV I can put things on top of the station and it won't slide off. The handles are study, if this is the only thing you are carrying at the moment, no problem. For the amount of power it stores, 50 lbs is about right. 85" TV and 350W speaker bar/sub 13 hrs run time. Yeah, I like this thing! 2: The Echo Flow 400W Solar Panel So, in full sun light, if you line it up to the sun exactly, I get about 389W of power coming through. to line it up close to what's needed to get max wattage, get the Solar Angle Guide. Changing the angle with the Solar Angle Guide 10 degrees, increased output from 326W to 384W. Well in that particular instance. In the evening shade, no direct sun light, I was getting about 36W of power. I've only completed one full charge during various times of the day. So I can't give you an exact how long it'd take from 30% or less with good sun light to charge with this panel. But I would say about 9hrs at least for a 70% charge? I need to play around with the charging more to a have a better idea on how long and what level of sun light. ... show more

  • Easy and works great!
Style: DELTA 2 Max+400W Solar Panel
Received the EcoFlow Delta 2 Max, 400w panel and solar extension cables days before hurricane Beryl (July 2024). It has been a huge relief and well worth the money! Today is our 4th day without electricity with temps in the mid 90s, heat advisory, heat index of 100 degrees and low to no wind. It's hot as hell! Unit arrived very well packaged and set up was very simple. The only negative comment regarding set up would be the solar panel case... the case is perfect for storage but flimsy when used as a stand. I made a stand out of gray pvc and it works great. About the generator... I plugged in the unit before the power outage and it fully charged in an hour. Display screen is bright and easy to read. The number of USB & AC outlets are extremely useful and it has outlets for 2 panels. Solar charing... there is a bit of a learning curve here and it has to be managed throughout the day. To get the best charge, the panel has to be adjusted throughout the day according to the sun position. I have been able to get over 300 watts for several hours on a sunny day. Watt usage... this is where you have to manage watts and the app is a battery saver!!! For example: During sunny midday I can get up to 309 watts coming in. With my 25 cu ft refrigerator, 1 oscillating fan and a TV plugged in, all of that has been using 220 watts. Banking more watts than what is being used! But, if I unplug the refrigerator (and not open it) for 4 hours the wattage usage drops to 100 (food stays cold). Banking even more watts! Managing the usage this way gets us through the day with 40% - 50% battery life at sunset. Unplugging the refrigerator for 4 hours overnight helps save watts until the sun comes up. Overall... I'm very happy with this product! So relieved that my grocery items are kept cool and I'm not out driving around looking for gas and ice! My only regret... not buying a small generator for use upstairs. ... show more
