Purchased the Ecoflow Delta 2 with extra battery around the holidays. It is used primarily as a backup to our pellet stove which is our primary source of heat in our home. Most of the time we keep it plugged directly into the Ecoflow Delta 2, but we have occasionally used it in our kitchen to run an appliance like a toaster. It is nice knowing that the inverter has the capability of handling that much electricity draw. We anticipate using it also as a backup for our sump pump during the warmer rainy months and also having the benefit of solar will a welcome feature.

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.

We bought a camper last year and wanted a battery and inverter option to allow us to work remotely. The Delta 2 is perfect because it’s small and lightweight relative to its capabilities. We also like being able to carry extra batteries as needed for more capacity but leaving them home when not needed. It’s also been great at home. We lost power for a day recently while I had an important meeting and it ran my entire work setup with plenty of charge left over. Highly recommend.

Very good power supply, I used the 400 W power supply from a Chevrolet 1500 to charge the power bank with no success. Then after passing through a 36 volt power converter it was fine. see Attachment. If there is a 48-volt 10-amp power converter, the charging power can reach 400 watts.

Hi, EcoFlow! I've already mentioned to your support, that your products are amazing. Be a Ukrainian and do not know the brand - it's a shame (: I bought Delta2 and Extra Battery 3 months ago and these guys help every day to survive the power outage and stay online, with heat and light. Really convenient to use. Look and feel are great. Efficiency is the top.

I bought this a mont ago and I'm so happy I did it. The product lasts so long, I didn't expect it was this good. I feel extremely succesfull by chosing this product. I know Ecoflow has a bright future ahead compared to their competitors. As someone from the industry, their ecosystem is modern, well built, and bug free.

I purchased this as a combo with the 220W solar panel a few months ago. It charges incredibly quickly via wall outlet and is easy to hook up a solar panel to. The screen is easy to read and the app is very convenient to monitor power input and delivery as well as control different features, such as charging/discharging limits or switching the different power ports on/off. I also purchased a weather-resistant cover which is nicely made. The top compartment is very convenient for storing cables. Here are some of the parts I dislike. The Auto Timeout feature is nice but can still trigger if you are powering something with low current, such as a string of LED lights. The app frequently takes a swipe down refresh to reconnect. Annoyingly, reconnecting to the station after leaving it overnight will sometimes be impossible until you physically power cycle the station. Even more annoying is if there are cables plugged in it can be difficult to power off the station until you unplug all cables. I have also noticed when camping with it, in the morning it did not start charging with direct light on the panel until I disconnected one of the solar panel cables and reconnected. The solar panel I purchased with it shows signs of the material around the grommets failing after a couple uses. It seems like a lot of weight to rely on grommets to hold up, especially when mounted in a semi flexible material. Overall the station itself is well built and has plenty of power for long term use. It has some annoying quirks, especially when using the app, but the unit itself is very good at what it does.

This unit is great! It seems to be just as portable as the river 2 max but way more capable. I got the waterproof bag and it is very worth it. The bag holds all of my cables and protects my Delta 2, while making it look unique! I’m excited to use this guy for many years.

I've been nervous during some past power outages, but when Tennessee Valley Authority required 5-10% reductions on the grid with what was barely a top 10 cold snap, I knew it was time. I decided on Ecoflow first, then on the Delta 2 as a great starting unit (will likely add a battery later). It was super easy to lift onto my counter, important for a woman of a "certain age", and very easy to set up. I've tested my refrigerator, Breville milk frother, my Nespresso machine, and electric blanket. All thumbs up! I also added on a solar panel, which was very easy to unpack and set up, but I haven't tested that yet. I'll leave a review under the panels when I do. And now its charging up again because an ice storm is rolling in.

Bought this to back up our fridge and run our gas furnace. Great set of features, and being able to plug it into a transfer switch opens up a world of opportunities. "Kelley's Country Life" on YouTube provides a great setup to run this like an automatic backup system. Few things that will make this product go from great to awesome: 1. Power input and output trending. A running graph of 24 hours usage in the app will help understand consumption and charging trends. 2. Provide the charging cable for the solar panels. I bought two rigid panels with this, but had to wait a week to get the cables. 3. Low power devices don't show usage, the device times out. Charging my smart watch shows output of 0W, so device turns off after the set timeout. I have to change the settings if I want to charge the watch fully.
