After 2 months of storage, I pulled in my refrigerator, fans, computer, TV and other devices during a power outage. I used it for hours cutting wood outside with my 18in electric chain saw as it was powering my class B motor home. It has changed the way I camp outdoors in my RV.

I received my Delta Pro earlier this year and charged it fully in just under 2 hours. I live in Kansas so needless to say, spring is severe storm season. My use case is simply to provide backup/emergency power. Knowing that I have 3.6kWh capacity to power a fridge, freezer, lights, tv, etc in the event of any power outage helps me sleep better at night. Even through the thunder and lightning!

I am working from home. This means I was not able to work and communicate with my team during power outages. I hooked up my work station, which is basically a notebook + double screen including my Comcast and the WiFi router to my DELTA Pro. This setup saved me a couple of times. I am covered 7-9 hours which is long enopught for the type of outages we have in our area.

I live in a rural area and suffer through at least a few multi-day outages every year. The worst one was during an ice storm right before Thanksgiving a few years ago that left us without power for a week and a half. Coming home to what feels like a cold campsite daily living off whatever you can make on a natural gas cooktop and warming yourself by the fireplace is not my idea of a relaxing evening. Add to that, my neighbors Generac’s taunting me with their loud engines all day and night. After that, I decided that I was going to do some research on the best option and spend the money on a system so that I’d never live through that again. I had a 10 circuit manual transfer switch installed at my home by an electrician. It allows me to plug in my 7500w gas generator or my 2 EcoFlow Delta Pros and 2 extra batteries via the dual voltage hub. This setup allows me to primarily run the quiet EcoFlow system at night and use the gas generator to re-charge my EcoFlow system during the day, or use it as the ultimate backup if needed. I have the following on my switch: Water Well Pump, Furnace/thermostat, Garage (internet modem location), basement, bathroom, kitchen (includes fridge, freezer, cooking appliances, lights), living room (TV, work from home office), master bedroom. The EcoFlow handles all of that with no issues. During my first test day, I took a long hot shower and had my furnace cranking on a 19 degree PA night. Ran my lights, TV, internet as usual and woke up the next day with plenty of power left. Coffee was brewed and the house was warm. Obviously, during a real outage, I’d be a bit more conservative on what I use to save the batteries a bit, but the point is that it’s capable of getting you through the night and beyond. I have tested the EcoFlow system and have found it to be able to power my home reliably and realistically for a little over 24 hours without needing to be recharged. I maintain my setup by running a monthly “fire drill”, connecting my EcoFlow system, shutting off the main breaker, turning on the transfer switch, and living as I would during an outage for a day. The next day, when my EcoFlows get down to about 20% left, I turn the main power back on, fire up my generator, and recharge the EcoFlows. Having a transfer switch installed and using the EcoFlow combined with a gas generator IS EXPENSIVE. Even on sale, this system is NOT cheap. However, it is still slightly less expensive than what I was quoted for a Generac full home natural gas generator installation. What I like about it is the fact that you can quietly power your home at night, have multiple refuel/recharge options, and most importantly, you’re not at the mercy of the power company, natural gas company, and the Generac repairman when your expensive unit ultimately fails. This setup allows me to plug and play anything strong enough to power my switch if anything happens to fail. You can’t do that with a Generac. My area has also had natural gas issues from time to time with low/no pressure. Again, that renders your Generac useless. I plan on buying another battery or 2 during one of the sales this year. I kind of regret not waiting for the Delta Pro Ultra to be released and buy that, but I am happy with this system. It’s disappointing that EcoFlow hasn’t made an easy adapter to connect the Delta Pro Ultra and Delta Pros. I know you can do it with the smart panel, but I already have a transfer switch that works perfectly fine. If you’re young and capable of maneuvering them and plugging things in and operating a transfer switch, this is a nice system. I’m so happy it’s on wheels! It would be nice if some of the cords, including the ones that are used to re-charge the units and the ones that connect the battery to the main unit, were longer. I am really hoping the price on this equipment continues to become more reasonable so people like me can have an affordable arsenal of backup power stored in their home for the next disaster that the power company didn’t prepare for and cannot fix in a reasonable amount of time.

I bought the Delta Pro about 3 months ago along with a spare battery. I’ve used it more than I thought and it has performed remarkably well. Mid sized home with a in garage business/shipping facility. I’ve had two complete power outages, one lasted 4 hours the other, 8.5. If I hadn’t had to connect the Delta, I wouldn’t have noticed the outage. All of the critical circuits remained online and the equipment performed flawlessly. I was so impressed with its performance, I bought a second. Then I bought a River Pro and a spare battery for it!

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.

I received my delta pro from kickstarter campaigned. Used it as ups for my home network rack which powers 200w of network equipment (router, PoE access points, PoE cameras etc, plus cooling fans). During a power outage in the neighborhood, my unit stopped working and showed some error codes. EcoFlow was very quick to help and send me a replacement unit. Never had issues since. Have the smart home panel too, but that still needs to be installed.

I bought a delta pro, extra battery, smart gen & solar panel and so far had 5 power outages some short some for up to 2 days worked perfect powering: refrigerator, PC & floor fan already used both input from smart gen and ac input from a second gen to charge before night and charged pretty fast. Great so far keep up the good work guys.

I purchased this as a backup for my house in case of blackouts (looking at you Texas power grid) and also to use with my RV when boondocking. It's been fantastic, especially considering a lot of sites don't allow generators but they do allow portable power stations. I was able to power my TV and microwave off the Delta Pro for the 3 nights we camped and still had plenty of backup storage.

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!
