The Delta Pro is one of the best purchases I've made in a while. We live in an area that is prone to several power outages each year, so I've been looking for a better solution than dragging out the generator each time. I've purchased two and an extra battery with the eventual goal of connecting them to our panel. All in all, this unit has performed exceptionally well. We are able to quickly plug in our critical items (refrigerator, freezer, TV and cable for the kids) and power everything within minutes, with enough power to last for a while. The display provides all the information you need to manage your usage, although I primarily use the app, which is also excellent. Although large, we can easily store them under our pantry counter, ready to go when needed. I go with a lower recharge speed generally, but if we have to get it charged in a hurry, I can adjust that in the app and get it done in less than two hours. It's heavy, but not unmanageable if you're in decent shape. Regardless, the wheels and handle make it easy to move around for just about anyone. Another feature I've enjoyed is the emergency power option. I moved one of our units to the garage, plugged it in the wall outlet, and use it to power our standing freezer. It powers the freezer from the outlet, but the unit will kick on in the event of an outage, giving us some peace of mind if we are out of town for a few days. All in all, this is a great product that gives us great options and flexibility. I look forward to continuing to build out my EcoFlow system.

This is my 4th EcoFlow product and it is by far the most impressive. I still use my old EcoFlow River more frequently due to its more compact/portable size, but the Pro has been amazing for providing power to our 30 amp RV when there is no TT30 hookups available.

I bought my delta pro and 1 extra battery on kick starter as I thought it was great technology. After receiving it, I was blown away. This system is amazing and to boot the customer service has been top notch. They have always gotten back to me within 24 hours with an answer to my needs and concerns as this is all new to me. I have been running it nonstop since I’ve had it taking 2 refrigerators, a freezer, all our internet gear, and our basement circuit off the grid. I’ve seen my electrical bill go down about 40.00 a month. If you are considering this equipment don’t hesitate as I’m a very honest person and would be the first to say if it was junk.

Just completed a 2 week travel by vehicle where I used the EcoFlow DELTA Pro to keep the refrigerator running in the vehicle. It never left the vehicle, and was charged by the 12 volt D/C charger while in operation. While visiting friends it sat in the driveway for 48 hours just working away. Dropped to about 85% state of charge, and when we were back on the road it regained most of it's charge by the next stop. I finally quit worrying about it, as it had no trouble at all with extended run time. I believe it could power that little fridge for 8 to 10 days without additional input. Only issue I had was had difficulty using the cigarette lighter in the car because the plug and outlet got very hot. I ended up making an adapter that clipped directly to the battery, and then no more heating issues were noted. It also powered my MoFi Internet hotspot the whole time we were gone. Glad I bought it!

I bought the system back in the Kickstarter days. Two Delta Pros, One Smart Extra Battery, 400W Solar Panel, One Extra Infinity Cable, and the Double Voltage Hub. Shipping delays, FedEx, and a DOA Smart Extra Battery created a few concerns. That said, customer support was very good. Responsive when you contact them and quick to resolve shipping and repair of the Smart Battery. Installation of the system went well after finding a competent Electrician in the area. Startup of the Smart Home Panel went reasonably well after multiple firmware updates. Initial scheduling of Charge and Discharge functions take some time. It is a bit clumsy and does seem to take a few days to incorporate the schedules. After the first week of actual operation I am very happy with the systems performance. The portability was the key to taking this approach to battery backup. I look forward to expanding the system in the future.

Last winter I bought an EcoFlow Delta Pro along w/ 400 watts of solar. This setup has allowed me to take my home office and the houses telco off the grid. The 3.6kWh of energy allows me to keep me connected and the office open even after a couple of grey days when the solar power is low or when those spring storms drop power for the rest of the house. I also use the extra power to keep all the battery powered devices around the house fully charged. I even power the mower - the sun makes the grass grow ... and allows me to keep it trimmed. The rig was all plug and play - great for those starting down the road of power independence.

I purchased the entire system (delta Pro plus 2 batteries) including the smart generator. I am impressed with the capacity, but very disappointed that I am not able to use the smart generator with both batteries hooked up. I have to physically disconnect 1 of the extra batteries to be able to use the smart generator. Consequently the second extra battery does not get charged. This to me is not a complete stand alone system! I may as well could have saved the cost of the smart generator and use one of my Honda 1000 to charge the main unit and the 2 batteries, since I have to manually switch plugs. This is a 10k purchase and i am very disappointed in not being able to use the smart generator on the entire system!

I purchased the Delta Pro generator along with a second battery in the 1800 W dual fuel generator also purchased two 400 W solar panels solar panels tested once early morning getting around 300 W pretty steady on one. Can’t wait to get contractor in get it all tied into the main frame looks like a good system will find out when first outage

I bought my Ecoflows a few months ago and i just started utilizing them. I also have a solar panel which i will be using to recharge the units. So far, they have run flawlessly. The display on the unit is helpful in letting you know how much capacity is left and about how long it will last. Overall, i am very satisfied and have recommended to my friends that are in the market for a battery.

I love this generator! I currently use it as my QUIET indoor generator when power issues arise. Also great to take on trips or for outdoor camping. I couple up the 220 Watt bi-facial solar panels and I am never without power. This thing is a beast and I also have the Delta mini for super portability or smaller jobs. Great customer service with phones answered very quickly and very different than all those reviews that knocked the customer support. I give them an A+ for customer support. Don’t wait because these solar generators were not available at the end of 2021!!
