We bought our Delta Pros (2) during the Kick Starter Promotion. We initially purchased them to provide off grid power for our campers when we finally purchase some property to build a Tiny House on. While we haven't actually used them for that purpose, we are usually busy with some remodeling project for one of our campers. The Delta Pro worked great when we decided to run some power tools inside our house. We usually work out in the barn that actually has a more reliable power supply than our old Victorian house. So instead of tripping breakers inside the house we plugged into the Delta Pro and had zero issues. Really looking forward to some off grid camping and eventually setting up our Tiny House and "guest campers" on our own property.

After owning a J***** 500 for a few months, I wanted something a bit more powerful that could serve as an emergency backup power source considering the outages from fires these last few years in Northern California. I stumbled upon the EcoFlow Delta Pro in a Facebook ad by chance and jumped at the opportunity of getting a battery with better battery chemistry (LFP) which should last a lot longer than my other NCM based battery. I was beyond thrilled when I received and tested my new Delta Pro. It has so many cool automated features like having it stop/start charging at certain threshold, connecting to my Delta Pro via wifi, and has a clean, intuitive interface that lets me know what’s going on without the need to look at the manual.

I’ve had this battery since January and I’ve loved it so much I’ve ordered another one just last week. It’s heavy (100 lbs) but it’s still portable and useful enough for me to take on camping trips this summer (along with the EcoFlow Wave) for a more luxurious camping experience. I’ve bought a couple of extra batteries for the Delta Pro as well and I should be better prepared for the next power outage. If you’re looking for the best portable emergency backup battery, you’ve found it.

We recently purchased the EcoFlow DELTA Pro and an extra smart battery to expand our power available. There was a terrible thunderstorm this past week that knocked out our power for several hours. If we didn't have the EcoFlow DELTA Pro and the extra smart battery, we would've been without power and no way to keep lights on, fridge/freezer running, and more importantly keep cool with our window unit plugged in. Thank you for making such an easy to use product! We will definitely be expanding further in the future!

I have been reading about possible outages coming our way so after doing due diligence I found Ecoflow. I bought one delta pro and liked it so much that I bought another Delta Pro, an extra battery, and two 400-watt solar panels. I have been charging my two refrigerators, my phone and laptop, blow-dryer and bedroom on my two delta pros with 650 watts all day long free of charge.

I have been looking for a while for a good portable generator with out gas. I have been looking at a lot of these and when the delta pro came out with the bigger outlet, that is what sold it for me. It is very easy to set up and to get the app and have all the info on it. Very easy to plug stuff in and have it work. The info on charging and the uses are great. with having freezers and extra fridges with food, its a must. I am not a preper, but this thing is a must if you have extra appliances that need to run when power is out. sump pumps in storm is a key if you have a basement. It can even charge your Tesla a little bit if needed. Sometimes you just need 5 to 10 miles to get to a charger and this back up gives piece of mind. Its expensive, but worth it. Lots of cycles in the batteries and the life seems to be long. It stores charge for a good while as well. Love the fact that is fully charges in 2 hours with the AC cord. So far I am a big fan of this unit.

Purchasing my delta pros has been the best investment ever. I feel confident that in the event of an emergency, these generators will provide energy for me and my entire household without interruption for at least a few days. Works great. Thank you EcoFlow!

I know this unit charges fast..My main reason for purchase is to hold my refrigerator at temp during a power outage and there are many in my area. I have yet to see how it hold up. I own another brand that hold well, but the downside is that it take HOURS to recharge like 6-10 hours. Hoping this brand does all it promises.

If you’re looking for a powerstation that has the best features in its class, the Delta Pro is the way to go. I spent months doing research between different brands to find a powerstation that fit my needs. Ecoflow surpassed all the others with the best specs. The ecosystem is upgradeable, and we recently added on another Delta Pro and preordered the a/c unit.

EcoFlow Delta Pro is a Game Changer when it comes to working in the outdoors. Whether its for a Film Project where you need to plug in lights, charge Batteries or for having a little Event in the Park or the Beach. Looking forward to get my Van to transport all of my gear + EcoFlow Delta Pro and do more outdoor events, cause be aware those Beats are crazy heavy, I mean all that power needs to be stored somewhere so it makes sense. Having the wheels and the suitcase pull function are great feature to move the Delta Pro around on the even floors, streets, pathways yet stairs or other uneven terrain is hard to handle and you would need to carry them. All in I feel like i have used it only to a fraction of the endless possibilities and freedom Delta Pro can give you. The ability to move around freely and always being able to fire up the most important equipment that is necessary to live your life or to do your work in todays technologically advanced world we are living in is impressive..
