  • Excellent product!!!!
Style: DELTA 3 Plus with 400W
This thing is awesome, we use it to run a deep freezer and lights in our enclosed trailer for shows. Battery stays at 95 percent during the day with the 400watt panel. It is dead in the morning but is recharged in an hour and 20 minutes on a generator with the freezer still connected and running. Bought a small pack to keep at our booth and it runs all our lights. ... show more

  • A Top-Tier Portable Power Solution!
Style: DELTA 3 Plus with 400W
Here's my honest review! The EF ECOFLOW DELTA 3 Plus with 400W Solar Panel is hands down one of the most impressive solar generators I’ve used. Whether you're prepping for emergencies or need portable power for camping or RV life, this system delivers. The 1000W solar input is a game-changer — paired with the included 400W panel, it charges surprisingly fast even in partial sunlight. I love that it uses an LFP (LiFePO4) battery, which means long-term durability, more charge cycles, and greater safety compared to traditional lithium-ion. The build quality is outstanding — solid, compact for the power it holds, and easy to move around with the built-in handles. The output options are versatile, with plenty of AC outlets, USB ports, and a car socket, making it easy to power everything from a CPAP machine to a fridge or laptop. Pros: *Fast solar charging with 1000W input (400W panel included) *Durable and safe LFP battery (long cycle life) *Great for home backup, outdoor use, or travel *Quiet operation and intuitive display * Wide range of output ports for multiple devices * Solid construction, reliable performance Cons: ➖ A bit heavy, but expected for this capacity ➖ Pricey — but you get top-tier features and battery life ... show more

  • The product is defective.
Style: DELTA 3 Plus with 400W
What a horrible product it’s defective it keeps turning off and had not charged my items. Echo Flow denied my return for a defective product. This is absolutely unacceptable!

  • So far so good!
Style: DELTA 3 Plus with 400W
Customer service is something that’s hard to find these days and Ecoflow has been great! The upgrade from my delta 2 was thoughtfully designed. I like the outlets on the front. I was happy with the delta 2, but unfortunately it burned out. I dethatched my 8,000sq. Ft. lawn with it with no issues
