Style: DELTA 3 Ultra
So far so good. Easy to setup, easy to use. Charged extremely fast or you can turn a switch in the back and slowly charge with setup through the app. App itself is straightforward and functionality seems great. Very easy to connect to Internet and Bluetooth. Have not needed to use it yet but think it will be very simple if and when I do. Purchased to run my refrigerator, a fan and WiFi if needed in a pinch. I will eventually upgrade to a whole home system, but this is great for a few necessity items at a fraction of the cost. Full warning, the Delta Ultra 3 cannot be tethered with any other unit or extra batteries for improved power or for extra time, but you could buy an adapter and wire it into your electrical main box if you want to. This particular unit would not be sufficient power for most homes, however. It is not capable of generating enough power nor for long enough. Portable enough and not huge (but not small). Has wheels and an extendable handle to help with movement. I have it in the corner of a room right now.

This particular unit is currently used as a full size refrigerator backup in case of power outages. In recent weeks we had a three hours power outage during a mid 90s outside temperature day in the recent hot summer weather. Needless to say, without the power for the air conditioning, the inside temperatures soared close to 95-96 degrees Fahrenheit causing our both refrigerators to slowly warm up over 45 degrees and, eventually, forcing us to discard more sensitive foods due to the higher temperatures. As such, after a thorough online research, we came upon the EcoFlow Delta power system that had quite a few superb reviews and it appeared to be the right system to use for our house. The unit arrived within a week after ordering, very nicely packaged and well protected in its original box. It is relatively heavy, probably close to 60 or 70 pounds, but it has two rear wheels and a front telescopic handle that pulls out and allows easy movement of the unit. Once connected to the wall power, it was fully charged in less than two hours allowing our refrigerator to be fully backed up for the foreseeable future, which seems to be close to 10 years or more. I downloaded the EcoFlow app on my phone to be able to monitor and make adjustments as needed from the distance. The unit is relatively easy to use and the app has a thorough user manual that can help with any questions. There are four AC three prong outlets in the front and various other USB connections, DC outlet. The back has the power cord connection, spaces for solar panels connections and additional EcoFlow extra batteries connecting slots to increase the total output, if needed. Overall we are quite pleased with this unit and we hope it will last us for the indicated time. We also have an EcoFlow Pro and a Delta 3 Max unit for other parts of the house. Definitely highly recommended if anyone needs any of those units.

This has been amazing! the fact that it has wheels and a strong handle makes this easy to move around. I would totally be an EcoFlow distributor because I’m constantly telling my friends and family to get this.

I purchased this as a backup electrical source for a home medical device, we have PG&E power company on the Central Coast of CA. Power outages are frequent during periods of inclement weather. Before the purchase I called customer support with a list of questions. They were most helpful. I watched YouTube videos also. Then I ordered through Amazon. It arrived before I expected it. Setup was easy. I had some questions during setting up the app. Customer support helped with that also. Am very happy with the product and support.
