EF ECOFLOW Portable Power Station DELTA 2, 1024Wh LiFePO4 (LFP) Battery, 1800W AC/100W USB-C Output, Solar Generator(Solar Panel Optional) for Home Backup Power, Camping & RVs

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.

⭐⭐⭐⭐⭐ "This Medline 3-in-1 Steel Bedside Commode is excellent! It's sturdy, easy to assemble, and very reliable. The quality of the materials is outstanding, providing great support and comfort. I highly recommend it to anyone in need of a durable and practical commode. Truly a lifesaver!"

This is my second ECOFlow product. We have a small off grid cabin in the Northern MI woods. We have 2 100 watt solar panels on the roof and a small HFT 2k inverter generator as well to charge the unit. The cabin is about 200 sq feet- think tiny house. We first purchased an ECOFlow river and quickly added the extra battery. It served the purpose of powering a few lights, celling fan, a small vacuum, and occasional TV watching . There was a charging issue that was resolved with our first unit. It did take a some time with the correspondence and supply chain to resolve the issue, however it was resolved and we are happy customers. This was during "COVID". As we added more amenities the capacity just wasn't there, a few more lights, a wall heater with a fan ect. On Black Friday we pulled the trigger on a ECOFlow Delta. We had a few issues with the capacity, it was our perceived capacity, the "use meter" was not calibrated or needed recalibration. After following the customer service advice- completely discharging and recharging the unit min of 3 times the perception of no capacity was no longer an issue. The units charge like a champ connected to the HFT 2k genset, the fans for the Delta are a bit loud, but come on, you are charging at 1200 watts!! Being in the woods, we don't like to run the generator any more than necessary- because we are in the woods and its quiet. the quick charging times are a huge selling point!! The 200 watts of solar is inadequate on most days- that's my issue not the product- more panels to come. We will also add another battery in the future to expand the storage capacity. We can run anything we desire, microwave, vacuum, charge power tools so far there's nothing we have not been able to power and we can be less mindful of run time with the delta vs the river. Running the furnace fan is a constant 30 watts of ac power while the burner is lit. So far, on the coldest nights around 0F with lots of run time we only use about 50% of the capacity. The phone app is really easy to use and gives you the status of the unit at a glance- any adjustments you need to make are just a finger tap away. We did turn off the "beep" the delta just seems to, in our opinion, just randomly beep- I am sure there is a reason but we don't want to hear it. This can be as hands off or as hands on as you want it to be. I do like the concept of the ECOFLOW ecosystem with the interconnected generator so everything is automatic and very hands off, however, that is way down the road for this little off gird git-a-way. All in all, I highly recommend this company, they are responsive and stand behind what they make. Update.. we added the delta2 extra batter which is awesome! There is an issue, it just stopped charging, same as the river did previous. It's going in for repair. Customer service is pretty responsive, however a bit redundant between the text chat and the emails from the company. But.... Will see how it goes... Make Shure you keep your boxes for shipping.

I am super impressed with Amazon delivery!! Ordered this generator yesterday , wasn't suppose to be delivered till next week. They delivered the next day!!! The ice storm is coming to NC tonight and the thoughtfulness of our local Amazon to get that generator to us is amazing. Thank you Amazon!! We are also impressed with the generator. Charges fully within 3 hours. Very simple to use. And very quiet too.

Outstanding Portable Power Solution for Home Backup and Beyond! I recently purchased the EF ECOFLOW DELTA 2 Portable Power Station, and it has truly exceeded my expectations. With its massive 1024Wh LiFePO4 (LFP) battery, I feel confident that I have reliable power during outages or outdoor adventures. The 1800W AC output and 100W USB-C ports offer versatile charging options for a variety of devices, from home electronics to laptops and even small appliances. What I really appreciate is its fast recharge capability and compatibility with solar panels—perfect for eco-conscious users looking for sustainability. The build quality is solid, and it's lightweight enough for easy portability. Whether it's used as a backup power source at home, during camping trips, or for emergency situations, the DELTA 2 delivers consistent, clean energy when I need it most.

Fantastic! I bought it for my 85 y/o mother so she feels safer during short power outages. The unit charges really fast. Easy to operate. Depending on what is plugged in and how much the device consumes, it tells you the amount of time the battery will last. It powers her refrigerator, microwave, toaster, coffee maker, Tv, internet, some lamps, helps change her cell phone and additional rechargeable devices such as flash-lights. NOT ALL TOGETHER AT THE SAME TIME of course. You need to use some judgement when powering devices with it. Simple maths, as it runs watts per hour. You need to check the reader to see how much watts are being consumed. Microwave is the worse because it can empty the battery in 30 minutes. But if you use a microwave a max of 10 minutes during a short power outage, you’ll have plenty of battery left for many hours running lamps, internet, computer, radio, and even get your refrigerator cold again. Used wisely, that’s an amazing power backup for short outages. I’ll buy one for my own home now.

Funcionou por 3 meses apenas

Excelente producto, su carga es rápida, he tenido corte de energía por la zona donde vivo y la estación de energía me ha ayudado mucho, la última vez conecté un pantalla de 65 pulgadas, un ventilador, el módem y carga de celular duro más de 4 horas, ya no continué utilizando porque llegó la energía eléctrica. En cuanto al vendedor excelente, llegó en tiempo el producto y en en excelentes condiciones.

Best part is the ease of use. Plug stuff in, push the little 'AC' or 'USB' on buttons and it just works. This unit keeps us powered remotely for exactly 3 days at a time between recharges - running light power tools (drills, etc.) and all the LED lights in our shipping container, plus charging phones, laptops and tablets. Fast recharge is great. We found it charges 10% per hour with the DC car charger while driving, and it's probably somewhat helpful for the life of the unit to have it charge slowly like this. Very pleased with it so far. Six month update - this continues to be one incredible power pack. Built an entire off-grid cabin from the ground up (including running the cement mixer) using only it and dual 100w solar panels to charge during the day. Also runs a log splitter like a champ. Only issue we had was recurring shutoffs last week with a blinking fan warning light indicating (apparently - who reads the manual until they have to?) a blocked fan. Blew about a pound of sawdust out of the poor little unit and she was back to working like new. Pro tip: Don't set this under the table saw while cutting hundreds of 2x6's! ;) Love the ability to access so much info (state of charge as %, time to charge, wattage draw in-and-out, etc.) via the digital display. We can keep an eye on it minute-by-minute to know when we have to plan a break to recharge and then still have power for overnight camp use. Looking forward to picking up one of the new Ecoflow 'Ultra' power packs in future, given how pleased we are with this smaller unit. 13 month update - still a solid 5-star experience and performing flawlessly - entirely off-grid and using the unit right now to power Starlink and computer. We've recharged it at least 400 times as we've used it every single day for all 13 months, and it has the same power reserve as when it was brand-new. Been a fantastic unit and now shopping for the additional battery for it just for some extra reserve time. The only thing I would like to see it have would be some kind of audible warning chime when reaching 5 or 10% power level - the first and only warning you get is total shutdown when it's out of power.

UPS use ,works great for satellite reciever , modem and TV, last about35 hours without any charging input, this unit switches reasonably fast , fan is loud., ITS WORTH IT !!!!!!
