Jason Molnar
Never fell overwhelm because of an unexpected power cut. These are the times I’m proud to be an EcoFlow owner. I am able to function as usual. Internet + Wi-Fi , lights, computer, tv and AC by the Wave2.
El Niño
Hope everyone in Hourton,Tx is safe, power went out like at 3am the portable a/c never missed a beat didn’t even know there was no power….. very thankful for having the solar set up….
Joe Lopez
Well...since Beryl just hit us with a vengeance. Ecoflow for the win!!!. Powered my fridge, freezer and internet modem to stay in touch!...I had a separate source for my movin' cool 14 classic AC unit...ALL GOOD!!!
Aline Tarullo
Our family went through hurricane Beryl without any hiccup with SHP, 3x DP + 1EB, hooked to 4600w solar array. It was no surprise that we did okay because Ecoflow has been running our house daily for almost a year now. Our electric bill went from $300 to $150. Estimated payoff time is September 2028, when the savings will surpass the $10k investment.
Victor M Roman
Extremely happy we got this ecoflow, all power went out about 30 min ago here in St cloud Florida. Hurricane Milton. We up and running.
Tony Fresco
A lot of posts had me scared. Installed this yesterday, updated the firmware to both (lots of errors while updating) but everything is working as it should. Shut my power yesterday 3pm @ 90% 8:30 am 71% left normal use including well pump. Only day 2 but nice so far
Hector Salgado
I am in Western NC and we were hit hard by the storm! Glad I got my delta max and delta 2 a few months ago. The combination of solar with a gas generator made all the difference! Generator ran for about 2 hrs in the morning and charged up my eco products for the day. Saving a ton of gas and noise! I had no trouble going 4 days till I got power back. 🙏

Emergency Power During Hurricane Helene in the US
In the wake of catastrophic Hurricane Helene in September, EcoFlow partnered with the Special Forces Charitable Trust and donated 10 portable power stations to help the most vulnerable homes recover after Hurricane Helene in September. EcoFlow has also partnered with the non-profit Red Lightning to preposition donated power stations and solar panels in Florida for future hurricane strikes.

Keep Maui Connected During 2023 Wildfires
In the summer of 2023, Hawaii faced power outages caused by wildfires. In a collaborative effort, EcoFlow and Blue Hawaiian Helicopter donated our products to support the powering of Starlink satellite broadband systems. This initiative ensures that the Maui community remains connected, enabling crucial assistance and maintaining connections with loved ones.

Texas Winter Storm
After the 2021 Texas snowstorm triggered widespread power outages, we donated all of the portable power stations in our Texas warehouse to the Houston Food Bank in support of local communities.

California Wildfires
