Title: Flimsy and bulk
Review: I bought this for my outside office, so was trying to move it out to where my solar panels meets the plugs. Moved it about 10 feet when I heard a crack from the castor wheels and the entire thing toppled over onto me, I got a few bruises and cuts. EcoFlow should’ve know if they labeled this durable and moveable, castor wheels should’ve lasted over at least FLAT concrete terrain AND at least more then 5 minutes and they even advertised 5 batteries AND a inverter, that didn’t even happen. The solar ports don’t work anymore and yes, I plugged them into other generators and they worked wonders pulling in more then 400w, but the solar ports don’t work anymore so I have to use the AC to charge the battery, I didn’t even get to use it and it already broke

Title: Heavy is the crown, when you’re the best
Review: 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.

Title: Powerful Battery
Review: With one battery we were able to power our necessary things for quite a while. Added another battery to extend the time.

Title: Great product
Review: 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.

Title: Battery storage is a necessity
Review: Increased capacity for Delta pro Ultra. Keep the lights on with this extra power. Run the fridge and freezer during power outages.
