I got the Delta 2 during the launch event, not realizing that just two weeks later I would be depending on it during Hurricane Ian. During the storm, we lost power and right away, I pressed the Delta 2 into service. The unit kept my refrigerator on for over 9 nine hours while the storm raged outside. Once the worst of the storm passed, I was able to start the generator and used it to recharge the Delta 2 in just about an hour. I love the app which shows how much charge is left and details about power input and output. I am now on day three without power and have already been through three-four cycles of using the battery and recharging it. It's currently powering my desktop computer and 43" monitor and it shows it could go another six hours. The Delta 2 is amazing, and it literally saved my bacon during Ian.

I was hoping to replace an aging APC UPS with this EcoFlow Delta 2. Options like solar charging and the longer lasting LifePo4 batteries were a big step up from the old school UPS I am currently using. Unfortunately the internal transfer relay is not nearly fast enough to switch from mains to inverter while keeping my home networking gear online. While EcoFlow does not list this unit as a UPS, or suitable for UPS duties, it is a little disappointing that the unit cant switch fast enough for my intended use. I'm still glad to have it for the other backup and emergency uses it brings though.

I’ve only had the Delta 2 for almost a week now, but I’ve tested it out for days with discharge and charge without issue. Fast charged and battery-friendly rate charge were both pretty quick. Total adjustability is a great feature. App is working good with no issues between the app and product.

I received my EcoFlow Delta 2 a few days ago. It was well packaged and delivered promptly. The initial charge (out-of-the-box) was 28%. I plugged this into my wall outlet and was amazed to see the charge power ramp up to about 1200 watts - absolutly amazing to see my new purchase charge this fast. Some folks have mentioned the loud fans. This is what I expected for the exceptional charge speed in this size package. I have been following EcoFlow for quite some time, waiting for the newer and safer battery technology to evolve with this product and the Delta 2 was worth the wait. I am a Ham Radio Operator and plan to use this as one of my remote, off-grid power options. My future plans will include the solar option with my Delta 2. Thank you EcoFlow.

We have been looking for a portable solar battery for tailgating and backyard football/movie watching. Watched and read many reviews and was excited when the Delta 2 came out and immediately purchased it. We already have 2-160w EcoFlow solar panels which we plan to use with the Delta 2. My only complaint is that although it can accept 500w charging, the 60 amp voltage limits it to 2 panels. Other than that, it is excellent and highly recommended.

I purchased my Delta 2 in September of 2022. I purchased it as an emergency backup for power outages. I also purchased the 160w solar panel array. I’ve tested the Delta 2 with various lights, heaters and appliances. It functioned without any problems and exceeded my expectations. I also tested the charging capabilities of the solar panel and was pleased with the result. During Christmas we were one outlet short of powering our DVD player to watch “A Christmas Story “. I powered up the Delta 2 and our traditional viewing of the Christmas classic was saved. Thanks EcoFlow!

After extensive use, I can honestly state the Delta 2 is amazing. It is used mainly for its portability in property management and electric power tools but I use it to power smaller kitchen appliances and electronic devices as well. I am NOT a fan of the folding solar panels which are so very expensive. But the solar generator is a very fine product and I have already demonstrated and recommended it to others.

We bought this before a big snow storm. We were going to lose power. Having to lose a fridge and freezer worth of food was not an option for us. Having the eco flow as a back up power source that was safe and not run on gas was a game changer! I now have peace of mind when we lose power. Great for charging the phones and computer for work and entertainment. So happy we made the decision to finally purchase this. I’m excited to take this camping with us this summer!

After months of reviewing various companies and their systems, we went with the EcoFlow Delta 2. We got two units, one for upstairs, one for downstairs, and a battery backup and a solar panel. When we received it, we literally opened the box, plugged it in, and very quickly (well under an hour?), it was fully charged! Truly a plug and play. The units are light enough to pick up and move around without a problem and to store in a small place. We haven't tried the battery backup or solar panels yet, but by every indication it will be a simple procedure as well. I love knowing that we can keep basics going now during a power outage, and have enough power to last quite a while, while being able to use the solar panels to recharge the units. If you feel intimated like we did, this is for you! Our next step will be to work up to a Pro for a whole house system, but until then we feel this was the best option for performance and price.

Back in fall of 2022 I bought Ecoflow Delta 2 and the second connected battery. I put them on a wire rolling cart and hooked our 28 cubic foot fridge to just the main battery. With only battery power the fridge ran for 22.4 hours. that was with us using it as usual. When I charged dead battery (actually 1%) It was charged in around an hour. With 1 hour runtime on generator it could handle fridge for a day. Thats huge leverage power for 10 plus years. I plan to also buy the PRO model when it gets updated.
