We live on rural Whidbey Island in Puget Sound near Seattle which has many wind storms and frequent 24+ hour power outages in the winter. We have had a small somewhat unreliable gas generator for several years and it was time to upgrade. After doing research it became obvious that the Delta 2 would be the best choice. The Delta 2 with solar panels arrived yesterday. It was very easy to set up and the App works well too. We did a test run of the Delta 2 yesterday evening. It went from 30% to 100% charge in just under an hour. Great! This means we can use our small gas generator only to charge the Delta 2 during extended outages. We ran the Delta 2 for several hours powering lights, a TV, Wi-Fi, and 2 small devices. Everything worked fine and no flickering lights or TV which we sometimes had with the gas generator. And we didn't have to run the noisy polluting gas generator. I expect to have a much more tolerable storm season this winter because of the Delta 2.

We live in an area with above ground power lines and outages occur after windy storms etc. We needed a generator to keep our fridge cool and have a backup power source to make the outages less of a concern. I did lots of research for gas generators but wasn’t happy about having to maintain them, go outside to start it, and run extension cords through the door or windows. Enter the Ecoflow! Although it won’t run as long as a gas generator, it’s so much more useful. The Delta2 is no bigger than a toaster oven and is light enough to carry with one hand. We have used it in the car for powering AC devices and otherwise keep it on the workbench where it’s ready for home backup. I prefer the battery chemistry in the Delta 2 and hope it will last longer then a traditional lithium ion pack. One feature I hope could be provided via software- it would help to be able to manage not just the AC charging speed, but be able to put it into a long term maintenance mode. I find that it continually uses power when plugged in and left on. It would be nice to have a storage mode where it only charges up if the storage drops below a threshold.

I am a 75 YO woman & bought my Delta 2 & 2 flexible solar panels to transition/downsize from a RV (Roadtrek, commercially built on a Promaster Hightop chassis) to a self build camper Ford Transit Connect. The old RV had a factory installed 200 watt solar w/ a 2000 watt inverter & 2 AGM batteries. The thought of trying to install a similar power source in a much smaller van was intimidating! Then I found this 27 pound Delta 2 self contained power station. Voila! I can easily lift it, it has a tiny footprint, & the flexible solar panels are light, portable & powerful. Meets all my needs. I can expand it to double size to bring in house if there is a power outage. Was reasonably priced for all the bells & whistles. I am delighted!

After extensive research and reading reviews, I decided on a new Delta 2. Shipping was quick and it came with all the necessary cables to start using it right away. Months of use later and I’m still extremely happy with my purchase. I would highly recommend one of these for any power down situation, camping, or emergency. It also features expandable battery storage so it can grow with my needs. I will be buying another one for my elderly parents.

We just installed a new propane fireplace in our off-grid cabin and having the Delta 2 was an important part of the decision. The 40kBTU unit has a 180CFM fan and is rated at 120 Volts, 1.8 Amps, 60 Hz (205 watts). While I'm happy with the power and profile of the Delta 2, the solar panels are cumbersome to set up compared to my other-brand solar generator (no clipping into position or separate carrying case needed). The ability to add an extra battery, however, is a serious plus for this application.

I originally bought this to be a power source for camping. However, i got to use temporarily until my power came back on to run my pellet stove. Easily movable and easy to use. Download the app and its a good way to keep an eye on usage and anything else. I like that I will be able to expand it if needed. Right now it's good for what i need.

Overall this is an excellent unit with plenty of features and options to customize how you want to use it. I'm personally using it for smaller devices so the 1800W capacity is nice but not necessary. New firmware updates have been brining even more features to the unit which is a plus. I tested the battery capacity and it exceeded the 1024 Wh stated capacity, so you're getting what you pay for. Also the LiFePO4 battery chemistry is far superior to other cell chemistries and is what utility-scale battery storage containers are using. Solar charging works extremely well. I was using (4) 100W Ecoflow panels in the winter and was able to get about 395 Watts using my professionally mounted patio chairs. Here's some of my recommendations to get the most life out of you battery: - If you're storing it for long periods of time, maintain the charge around 40%. - Most utilities set the charge settings to be 98% and discharge down to 2% and they cycle batteries almost daily. I'm not running my unit that hard but keep the 2% and 98% setting the same. - Minimize the depth of discharge. Discharging from 100% to 0% will degrade the battery faster than discharging from 100% to 50%. If you're cycling the battery every day I'd recommend doing further research. - Enable slow charging. It adds less thermal stress to the components and there's no point to use the fast charge unless you're in a hurry. - You may notice it will discharge for a while around 0-1%. The same thing happens with grid-scale batteries. I would recommend discharging the battery fully, recharging to 100%, then discharging it back to 0% at least 2 times. This will help train the the battery control unit to be more accurate. Other observations: - The unit is fairly heavy but the carry handles are well built and I felt comfortable carrying it one-handed by a single handle. -I use the unit for powering my modem/router and the UPS feature switches fast enough so they maintain power upon loss of AC to the unit. There is a very short delay (30ms I think per the manual) so critical non-capacitive loads may cut out. - The fan is fairly loud/high pitch around the max output. Around 1000 watts it sounds like a regular fan. - There is an 'AC Always On' setting. This will keep the AC outlet relay energized and will slowly drain the battery, even if no AC loads are on.

I’ve had this for several months now and I’m very pleased with its performance. It serves as a back-up power source for my home theater system and several other components such as a Wi-Fi extender and home theater peripherals. It has plenty of power to be able to operate the devices for several hours.

Back in fall of 2022 I bought Ecoflow Delta 2 and the second connected battery. I put them on a wire rolling cart and hooked our 28 cubic foot fridge to just the main battery. With only battery power the fridge ran for 22.4 hours. that was with us using it as usual. When I charged dead battery (actually 1%) It was charged in around an hour. With 1 hour runtime on generator it could handle fridge for a day. Thats huge leverage power for 10 plus years. I plan to also buy the PRO model when it gets updated.

After looking at a lot of different options I came to the conclusion this was clearly the best product of its kind out there. It also helps that the price point is roughly the same as other brands but you get a lot more. For instance the solar panel is bigger. For the same size unit. All you need to do is compare the features and Eco flow comes out on top
