I read a lot of reviews and watched many videos before buying the Ecoflow Delta2. My main use for this Delta2 is for overnight camping trips and use as a back-up power in case of black-out conditions to run some equipment like Refrigerator and be able to heat food using the microwave. Delta2 doesn't have the battery capacity like Delta Pro but with a good solar panel it can definitely come handy when required. One can always add an additional battery that again works seamlessly to extend the battery capacity or buy the Ecoflow Smart Generator. I was debating between Bluetti EB70s and Ecofow Delta2. The reason I bought Delta 2 over Bluetti was the battery capacity. Delta 2 provides 1024WH as compared to the 716WH from the EB70s. Delta 2 met the power requirements that I was looking for. I could not find any offering by Bluetti in the range of 1000WH capacity. Delta 2 was of course more expensive than Bluetti but the surge power (also called X-BOOST by Ecoflow) is really high. So running a microwave for a short time or a coffee machine at a campsite or picnic is not an issue at all. I bought a combo pack (Delta 2 and solar panel). More about this combo later in the review. The other reason was the 5 year warranty that comes with the Ecoflow Delta2 vs 2 years for Bluetti. Some models from Bluetti do offer 4 years but were expensive for my use. Below are a few things I like about Ecoflow Delta2 after using it for sometime. 1) Construction - This is a solid built product. The bottom edges have these rubber bumpers for extra protection. The form factor is designed well to fit in the car. I hope the handles were not protruding out as they are now and were more integrated into the main box. The box is strong and one can easily put heavy items on the top without any issues. With the LFP battery and 3000 battery cycles, the Delta 2 will last forever. 2) Display - It's big and clear. Very easy to read even on a bright day. All the connections that are turned on are shown on the display even when a load is not connected but for USB only when a load is connected, the icon is displayed. Not sure why only the USB icon behaves like that. Not an issue at all but just wondering why a different behavior as compared to other connections. 3) App and Connectivity - The phone app works great and it's very easy to use. There are so many options that you can set via the app. Connecting the Delta 2 to the app was a breeze. It connects to WiFi without any issue and also to bluetooth. The app shows correct data 99.9% of the time. Once in a while you have to refresh (close/open) the app to get the latest data. It is very rare but I did notice it. When the WiFi is available, the Delta 2 connects via WiFi. If there is no WiFi connection, it automatically switches to Bluetooth connection. The connection is just seamless and you are always connected to the Delta 2. 4) Charging - Delta 2 can charge at a whopping 1200W to be ready from 0% to 100% in about just 80 minutes. The fans do kick-in to dissipate all the heat generated during this fast charging. I personally charge the unit at 500 W with fan running but much less noisier and may be better for the battery life. The solar charging can go up to 500 W. I don't have enough solar panels to check that max limit but this can be a really handy feature during a blackout conditions or with limited hours of sun during camping. One can charge the battery before leaving camping or any other work. Charge while driving from the 12V DC outlet in the car (Also known as the Cigarette lighter port) and the battery will be 100% when you reach your camp/work site. 5) Output Connections - There are more than enough connections that one can use, in my view. With a massive 1800 W peak capacity and 2700 W of surge capacity, I think you can run almost any home appliance with this Delta 2. The provided ports like USB A, USB C, Power Outlets and 12 V (Car type) are good to power any device you may have. Now coming to the combo I got. I bought the combo of Delta 2 and Solar Panels that were rigid. I was not happy with the size and format of rigid panels so I reached the Ecoflow support team. Even though I made that choice and now wanted to get portable panels, the Ecoflow team worked with me. The support team was amazing with quick responses and answering all the questions I had. It was good to see Ecoflow believes in good customer service that still cares about their customers. One of the best customer service teams I have worked with. One option that I would like Ecoflow to add will be to set the discharging and charging percentages even when connected to the power outlet. I would like to connect a solar panel for charging and connect my garage refrigerator to Delta 2 and use the battery power. If the battery falls below a certain level (let's say 30%) it can charge via the power outlet, else the refrigerator can keep running via the solar power. This option is provided when you connect a Ecoflow smart generator to Delta 2 but not when connected to a power outlet. I hope Ecoflow will implement this feature in the future software update.

The EcoFlow DELTA 2 has been one of the best portable power stations I’ve owned. It combines excellent power capacity with fast charging and a compact design that’s easy to transport. Whether I’m using it for camping, road trips, outdoor projects, or as a backup during power outages, it has performed flawlessly. One of the standout features is how quickly it recharges. I was impressed by how little time it takes to go from a low battery to fully charged, making it ready whenever I need it. It also powers multiple devices at the same time without any issues, including laptops, small appliances, power tools, phones, and other electronics. The output remains stable, and I haven’t experienced any unexpected shutdowns or performance drops. The display is bright and easy to read, providing useful information such as battery percentage, input and output power, and estimated runtime. The controls are simple, and the overall build quality feels premium and durable. Despite its impressive capacity, it’s still portable enough to move around without much effort. Another feature I really appreciate is the ability to expand the battery capacity and pair it with solar panels, making it a great long-term investment for emergency preparedness or off-grid use. The companion app is also convenient for monitoring and controlling the unit remotely. Overall, this is a high-quality, dependable power station that delivers exactly what it promises. If you’re looking for a reliable backup power solution or a portable energy source for travel and outdoor adventures, the EcoFlow DELTA 2 is an excellent choice and well worth the investment. Highly recommended.

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.

Fantastic little power station. Used to power our mirror photobooth during an event and kept the area beautifully cable free so no trip hazards! Was able to run the booth which has a camera, mini PC, LED lights x 2 AND a spare fill light for nearly 6 hours! Very rapid charge time. 0 to 100% in just under an hour on AC power. Looking to expand to add solar panel next! Device is very portable easy to carry by handles short distances. Plan to also purchase and carrier case to make it even easier.

I've paired this with EcoFlow's "Smart Battery" and am pleased with its performance plus EcoFlow's support (it swapped out, via free shipping, the first unit that had an operational problem). I use it 24/7/365, powered by two Canadian Solar 455W solar panels arranged in parallel, to permanently, on-grid/off-grid power my kitchen refrigerator. During sunny days (South GA, USA) this rig reaches 100% charge by 2:00 - 4:00 p.m. (as of November 15, 2025) and makes it through the night. During grey days, it does not, but its "pass-through" circuit automatically draws power (through the refrigerator's regular wall plug) to compensate. So, you plug your refrigerator into the Delta-2 and then the Delta-2 into the refrigerator's wall plug. That's what I mean by "on-grid/off-grid." Shop on Black Friday for the better deal: The Bluetti Elite 200 V2 (I bought two, for $664 apiece, during Amazon's Prime Day in July 2025). It's newer (EV-grade battery) tech and more efficient. It also matches the Delta-2 + Smart Battery's capacity (never buy less than 2KW output and 2KWH battery capacity). Running an identical solar-powered array, my V2s power my other two refrigeration loads more efficiently (they consume less of what's called "inverter idle power consumption" and discharge at a slower rate). Put another way, their "Return Efficiency" (if you put in 100 units of power, how many units do you get back?) is higher. Again, the V2 is later and better tech and, unsurprisingly, packs a better warranty (Bluetti, too, has accorded me excellent support). Finally, for my next "load" (my PC workstation), I might go for the Pecron E3600LFP (a little less efficient than the V2) to complete my "Fractional Power Wall" plan because it might (on Black Friday) fall below $999 and, even at that price, you get more bang for your buck capacity/performance-wise (a third more power and battery capacity). Don't hesitate to ask A.I. bots, by the way, to compare price/performance ratios for the solar generators that you are considering. Fractional Power Wall: Under this method, you can do what I've been doing. Each "refrigeration array" (two 455W solar panels, wiring, a V2) has cost me (DIY-installation only) about $1200. So now I've got, on an incremental basis, parts of my home nearly 100% "off-grid" with a built-in generator: Those "loads" run (except when grey days come along) 24/7/365 off the sun, just as one can achieve with a $15,000 - $20,000 Tesla Power Wall. But my rigs are installed in a modular, incremental (hence, cash-flow permitting) way. Bonus: If a Tesla Power Wall component fails, the whole system goes down until expert repair addresses it. Under the Fractional Power Wall method, each independent array -- which requires NO permit or power-company consent -- cannot in any way affect the other. And more often than not, the vendor (here EcoFlow, Bluetti) will quickly address the issue via email or free-shipping unit swap-out. That's built-in, added resiliency and redundancy. And, of course, reduced power bills. With no professional skills, even a 70-year-old man like me can achieve this (attend "YouTube University" to learn how to mount solar panels; fortunately, the industry has listened, and it's now mostly "plug-and-play"). Pair each solar generator with a "mini-solar array" and it'll qualify for the 30% tax credit expiring on 12/31/25.
