Style: DELTA 2
I bought the EcoFlow DELTA 2 along with the add-on battery and 400W solar panels a little over a year ago as a home backup solution—mainly for power outages during extreme weather. After owning and using this setup for over a year, I can say it’s held up very well and has done exactly what I wanted: reliable, ready-to-go backup power that doesn’t feel like a “toy” when you actually need it. Why I chose this setup: I wasn’t looking for something that only charges phones. I wanted a system I could depend on when the grid goes down—something I can: - Keep charged and ready - Scale up beyond 1 kWh - Recharge from solar if outages last longer than expected The DELTA 2 + extra battery checks those boxes in a clean, modular way. What I like most: 1) It’s been durable and dependable for over a year. The main unit and extra battery have both held up very well so far. That’s the biggest compliment I can give any “emergency” purchase—when you buy it for insurance, you want it to still be solid later. 2) The extra battery is worth it. The base unit is great, but pairing it with the add-on battery takes it from “nice backup” to something that feels legitimately useful in longer outages. More runtime means less stress. 3) Solar makes it a real resilience tool, not just a big battery. Having 400W of solar means I’m not purely dependent on wall charging. Even if you’re not trying to run your whole house, solar gives you the ability to replenish power during extended outages, which is exactly why I bought it. 4) It’s fast and practical to recharge and keep ready. One of the underrated things about EcoFlow is you can top it off quickly and keep the system “prepared” without it being a chore. What I’d tell someone considering it: If you’re buying for extreme weather / outages, I strongly recommend budgeting for the extra battery. If you want true outage resilience, adding solar is what turns it into a more complete plan—especially if outages can last more than a day. Whenever this setup eventually gives out, I'll definitely consider replacing with another Ecoflow product.

I downloaded the app from the App Store. I’m sure my CCP monitor will approve of this review. Intended use of my units: partial home power backup for small devices/appliances while experiencing a power outage. To be a stop gap while generator setup is performed. Would then be used for nighttime operations of refrigerators and tv setup to relieve generator. There are several more in depth reviews with users having utilized killawatt plugs or an oscilloscope. I have not done this. This review is based upon a single test use only, but I am pleased to this point with only one small gripe. The gripe first. I purchased two Ecoflow Delta 2 units on Black Friday for a considerable discount. One of the two (this one) was a Delta 2/200W (x2 100W panels) solar panel combo. The gripe is related to the solar panel. The unit is supplied with the connectors to link the panels which is as expected. However, the panel to PSS cable isn’t particularly long. If you want to say…leave the battery unit inside while your panels are mounted outside while you charge…well, you will need a male to female XT60 extension. That’s a small gripe, but it will mean another purchase. A 15’ cable inside of the 6’ cable would let me put panels outside while my Delta 2 is more safely kept inside. End gripe The unit seems reasonably sturdy in built. The assembly is tight and nothing rattles or creaks. The fan runs during charging and discharging as needed. It is not particularly loud in my opinion, but this is quite subjective and some may be more sensitive. The display on the unit is adequate telling you remaining charge and consumption rate while using or remaining charge time and input rate when using the AC cord or panels. The app is actually pretty good and easy to use. The unit can be turned on (at the device of course) and left in standby mode with no outlets active until you decide to power them up/down via the manual button or the app. I have not tested how long the device keeps charge while in standby and no outlets active but without load. This would take a long time and I do not see the point of leaving it in perpetual standby. I do like that you can designate upper charge capacity and lower discharge limits via the app. To me, this makes maintaining the device much simpler. I recognize that some will not appreciate the idea of limiting how fully you charge the device as it cannot be known when an outage will happen. Many will want to keep the device fully charged. I plan to follow Ecoflow’s guidelines for maintenance and charge state between actual need of the units. While LiFePO4 batteries are more forgiving, these are expensive and I’d like to keep them within warranty. This is why I got the solar panel option to supplement charging from my generator during an outage. The Deltas can power small items to give the generator a break at night or during oil changes and refueling or simply to help save fuel. The unit is about 27lb. It is not overly heavy for its size but take this into consideration as you may not want to move it a lot during use/storage (see gripe about XT60 cord length). It is early, but so far I am very happy with the quality and capacity of the units. One will run my stove blower for hours, or power the entertainment center for several hours and a refrigerator overnight based upon observed rate of discharge. These appear to be a good supplement to an outage protection plan.
