Great way to power your portable power station

SerafinaNovember 21, 2025

Used this battery to battery charger on multiple long-distance trips to help power my Ecoflow Delta Max portable power station and it worked well. I did turn down the output of 800 watts to 400 watts, on the Ecoflow app, in order to protect my vehicle. Read more

Great solution to a gas generator

edward depaolaOctober 29, 2024

Where we live there are occasional power outages, not too often, we have a generac portable generator that we used in HURRICANE SANDY, we don’t have the budget for for a $12k plus standby system, so looking at the Ecoflow Delta 2 max seemed like a good option, got it on prime day deals with 4 100 watt solar panels, I have an interlock on my breaker panel so was easy to use, tried it after fully charging it, was able to power whatever circuits I wanted easily, fridge tv lights, between the solar panels, 12 v and 110 charging could probably run indefinitely, when no sun and no power, can start the portable generator for an hour to charge it, overall it’s a good solution, if anyone is worried about the gas generator, it’s 5 gallons so if needed running it an hour a day the 5 gallons would probably last more then a week, , and the Ecoflow is much easier to connect, no noise no fumes and can be used inside my house $1300 vs $12k is a nice option that works well for us Read more

Better than expected.

Dan S.July 6, 2024

I bought this unit based on many comparison videos on the interwebs. Researched a number of days. After receiving and testing I liked it. Then the power went out. It ran my refrigerator for the 10+ hours until power was restored. It still had 40% left. The 4 solar panels charged it back up in around 6 hours with periods of clouds. I was impressed enough to get one of the add on battery units which doubles my capacity. Hurricane season is here! Read more

EchoFlow is the best!

Michael E.May 8, 2025

Bought 3 of them when the price was just right. Using 1 of them as a uninterrupted power supply and line noise filter in my RV when camping (packed campgrounds often have unstable and dirty grid power). Love it. EcoFlow is the best. What more can I say? Read more

LIfe saver for outages, camping and natural disasters.

MaryOctober 6, 2025

I love ecoFlow products and their customer service. I have bought 5 of these. Sent a few to Puerto Rico. Really nice to have this back up for our every day needs. Read more

★☆☆☆☆

Avoid at All Cost. Doesn't work. No Customer Service. Waste of Time & Money.

Kindle CustomerDecember 12, 2024

All the lights are on on the front LCD screen. Yes - all. I called customer service and spent 30 minutes only to be told that they can't (or won't help). They said that they would take my e-mail address and communicate with me that way. It's been 24 hours - no communication. They told me to hold the power button for down for 10 seconds, that the Delta2Max would do a hard reset after an hour. Done - no change. Called them back - wasted more time. No help. The instruction manual is useless. The Ecoflow videos are all about selling - not about troubleshooting or how to use. I spent $5,000. Really aggravated... Read more
