Style: DELTA 3 Max
The EcoFlow DELTA 3 Max has been a game-changer for me. The ultra-fast charging is unreal—0–80% in just about an hour means I can top it off before a camping trip or keep it ready at home for backup. I love the flexibility of charging it multiple ways, whether from the wall, solar, or even in the car. I’ve used it to keep the fridge and lights running during a short outage, and it handled everything with no problem. Super reliable and easy to use.

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.

Style: DELTA 2 Max+400W Solar Panel
The main reason I bought the battery was to have a power backup due to the constant blackouts that occur here. As I learned, I realized that it not only serves as a backup battery but also supplies free energy (via the solar panels) to the areas with the most electricity consumption in my house (kitchen, laundry room, my office etc..., which is where we spend most of the day). It works as an inverter. While the two 575-watt panels recharge the battery at the two charging ports, the battery supplies voltage at the same time, and when the sun goes down, the consuming power without needing the grid electricity (using just the battery). This has reduced my consumption electricity bill by more than half. It's a super powerful device and really worth the investment. P.D it is really funny when the entire block is without power and just my home totally lighted, I really enjoy it when everyone turns their head and look like asking them self why this house has electricity? lol
