Great Refrigerator Saver or Home Office Backup!
on September 29, 2022

I bought the Delta 2 primarily as a backup power source for my refrigerator during any short power outages this winter. I can also use it as a backup power supply for my home office or a small freezer if needed.
As a test, I hooked up a laptop with additional 21" and 32" monitors while working today. I also periodically ran a 15-watt lamp, a second desktop computer, and charged some devices. The Delta 2 provided exactly 10 hours of power. According to the Kill-A-Watt P3 power meter it was approximately 780 watt hours out of the listed 1024 for an overall efficiency of 76.2%. To be honest I was hoping for more, but I do plan on picking up the extra battery. However, the basic amount should be enough to get the refrigerator and maybe a small chest freezer through the night during a short power outage.
For solar charging I picked up two 160-watt EcoFlow panels. I set the two panels up on my back porch and tracked the sun from mid-morning to mid-afternoon. The two panels generated a maximum of 250 watts of input with clear skies but noticeable wildfire smoke. I was able to bring the battery up from 30% to 80% before the trees blocked out the sun. Solar panel efficiency dropped off quickly with any shading.
I experimented with parallel and series wiring as shown in the manual. I found I got a little more wattage out of the series method. When I looked at the specs I think that was because in parallel I was exceeding the 15 watt maximum input and it was throttled down by the control system. Adding a third panel would max out the system on volts and watts, and it might be worth considering for winter charging with fewer hours of less intense sunlight. These three panels could only be hooked up in series.
AC charging was fast! I actually tempered the charging to 800 watts maximum instead of the standard 1200 watts to reduce the amperage, but even with input reduced by one third a full charge from 0% to 100% took less than 2 hours. The fan runs the entire time the unit is charging. It is noticeable but not loud.
Overall I feel this is a great item to have on standby for short power outages. It can power small appliances and a computer for a significant amount of time when needed. Set up is fast and easy. The 160-watt solar panels are fairly lightweight and appear to be more durable than glass panels. The manual should do a better job of explaining the differences between parallel and series options (that might be a good feature for the app). The Delta 2 is manageable in size and weight and would even fit in an RV for mobile power needs.
I would recommend this to a friend!

Game Changer!!

I have only had my Delta 2 about a week, but it has already been a game changer for me. It has become central to my quality of life. With 1800w of AC output in such a small and complete package I now can move more freely while maintaining my ability control my environment. I have severe food allergies and the Delta 2 allows me to take my food preparation on the road with me so that I can insure my food is allergen free and cooked to my preference. No more cold, water logged food on the go. I now have a small refrigerator, induction burner, and water pot in the trunk of my car, or in my SUV. I can pull over at the time and location of my choice and by doing so level out the nutritional intake that curbs the peaks and valleys associated with delayed meals. The Delta 2 is easy to use, has ample charging options, and is rock solid in its performance. Game changer and life changer.

Just in time for Hurricane Ian
on September 28, 2022

Received my Delta 2 a couple days ago as Hurricane Ian took aim at Florida. The manual was clear and easy to follow. When I turned it on, it showed 27% charged. From the wall outlet, it charged fully in less than 40 minutes. This morning, no power thanks to Ian, so I put Delta 2 to the test. First a couple of LED lights and a fan, then the most important thing to start my day .... my Keurig coffee machine. It brewed two large cups of coffee effortlessly, peaking at about 1376 watts. Yes the fan was audible for a few minutes but not nearly as intolerable as a generator. Then for the heck of it, I plugged in a 10,000 BTU 16 EER air conditioner and Delta 2 did not skip a beat to get it running. I ran the AC for about 10 minutes just to cool a bit and lower the humidity. I also ran the refrigerator a couple of times until the compressor went off. In the mean time I connected the solar panel. There wasn't much sunshine but I still got about 120-130 watts. at the end of the day, my Delta 2 sat at 89% SOC, enough to get me through the night. This little beast performed flawlessly and was so simple and intuitive to use. I will definitely be getting an additional battery and solar panel. This will be a great creature comfort to go camping or picnicking.

Great power back up delta 2 ecoflow

This ecoflow delta I got , is portable and very convenient to use. Also do not forgot to buy solar panel which also help to gain extra free power from the sun. Any parts you need afterward you can order from company website very quickly. They are fast and efficient. I strongly recommend everyone looking into this , also because This is new generation battery you can charge faster and more time than old delta model. Again I will recommend this to my relative if they look for back up power generation device and also solar capacity.

The Features and App were great!

I just received my EcoFlow Delta 2 today and everything that was suppose come in package arrived in the box. The Delta 2 was in perfect condition with a 29% charge. I downloaded the App and proceeded to charge it to 100% and I was to change the charge rate easily with the App. The Screen is very easy to see with all the parameters clear and understandable. I am confident when I need the power I will have it and I will order the Delta 2 Smart Battery to supplement the WattHours.

Awesome Emergency Backup Power Source!

I received my EcoFlow Delta 2 today. (Just waiting for my solar panels to arrive that we’re shipped separately…) I charged it to full capacity by plugging it in to see just exactly what it could do. I connected a vacuum to it to see just how much of a pull it would be on the system. After 10 minutes, it still had 99% charge. I then took it with me outside to run my air compressor for another 8 minutes. It didn’t drop at all. I’m totally impressed! I’m so glad to see a good emergency product be put out on the market these days. I’m going to recommend this system to all of my friends and family! Thank for coming through on your word with such a good product for the price!

Awesomeness

Bought this a few weeks ago and haven't run into any issues. Summer is pretty brutal here but a quick 45 minute drive will get me to Lowe temps. It's nice to have a cooler but hated the thought of having items floating. Got myself a nice cooler /freezer so this delta and the extra battery is going to keep it going for the weekend. Also, starting a remote job and this bank will come in handy to power the RV Starlink dish for internet.
The design and quality of this product is really good. I had the River Max and it's about the same quality. The only thing you might need to get use to is when the 3 fans are blowing full speed.
