    • Heavy is the crown, when you’re the best
Style: DELTA Pro Ultra Battery
Man are these things heavy! I’m not weak, I have a toddler I must raise above my head at least 100 times a day - and she weights 25 lbs, so that’s easily 2,500 pounds I curl each day…. But god bless my FedEx driver for not burning my house down because when I ordered 3 batteries and the head unit, I had no idea that these things weight 120lbs a piece. And I’m not a scientist but for some reason, things tend to be heavier in the winter time! So after I only slightly struggle to get these into my garage, I unbox them all like a kid at Christmas - and let me tell you, it is as easy as legos to put together. It all just makes sense. Have them all charged up and waiting for the electrician to come this week to install the Smart panel 2, so we will be all set for a few days should the amazing Texas power grid decide to crap out. They are expensive but I plan to continue to buy more batteries in the future to protect my family and home. ... show more

    • Where are my D_m batteries
Style: DELTA Pro Ultra Battery
You sent the inventor ..but..I can't turn this on without a battery ! EcoFlow says it is Amazon shipping policy that they had to send just the invertor and now Amazon shows the order closed when it is NOT. I am to the point of ending doing business with Amazon, Amazon Chase and EcoFlow. I bet they will want to say my warranty starts when I got the inventor ONLY. BS. Very unhappy. If go to the EcoFlow web site they arn't shipping until Sep. That will be over a 1 1/2 month since my order. ... show more

    • Great product
Style: DELTA Pro Ultra with Extra Battery
Bought this with 2 batteries for vanlife. Got it on sale and used prime card for more savings. Works as expected, runs my window AC and everything else fine. The only issue is that charging from an EV charger never reaches 7200w. It only goes up to 6000w. An extra 1200w would be nice, thats 10% of extra charge (since i have 2 batteries) per hour. ... show more

    • better than powerwall by a mile
Style: DELTA Pro Ultra Battery
So far I love this product, it has made possible the ability to have whole house backup without all the nonsense of the powerwall it has its own inverter, its own charger and the multiple ways to to charge. It has a 6kw capacity per battery and expandable! The cost is substantially less expensive than the alternative. So far 5 stars! ... show more

    • Ecoflow is a caring company
Style: DELTA Pro Ultra with Extra Battery
After giving 2 stars when I did not receive the batteries, Ecoflow has been in touch with me several times. They apologized and showed they care about the customers.
