The battery powered backup you need

First, the setup couldn't be easier. Once charged, learning to operate it is a snap. Kudos to EcoFlow. Mine came with a 30% charge and it took about an hour to fully charge. I used my provider's electricity to charge it and not solar panels. And the app is fantastic. I recommend installing the app for the best experience. It tells you everything you need to know about the unit. I'm overly impressed. So, I performed the test for the reason I bought this unit. Does it power my fridge? Yes, it manages the initial surge like a champion. I live in California and if you've been following, we have grid problems. The unit estimated that I can run it for 24 hours. Even if I only get 10-12 hours it's worth the price.

Quality and Performance

I purchased the Eco-flow to give me a backup during a power outage. I live in a condo where gas-powered generators are not allowed, so a solar-powered generator was my next choice. I am happy with the quality of the materials used, the short time needed to fully charge, and the performance of the unit. The unit lasted for a day and a half running my chest freezer. The charging time is one hour, though on my kitchen circuit using GFI’s the time was considerably longer. Overall, I am very happy with the Eco-flow and highly recommend it.

Great power backup

It is a Portable Power Station DELTA 2 Max made by ECOFLOW. They call it a Solar Generator however it is a 2048Wh battery unit. It does not CREATE power so it is not a generator. Once charged it can be used to power devices like a cell phone charger, refrigerator, or even an air conditioner. Using this as a backup solution for your home is also a good option as it provides plenty of power for many of the things you'd want to utilize during a power outage like a deep freezer, Wi-Fi router, Television, Microwave, CPAP, coffee maker, chargers, etc.

April Barsobia

has been PERFECT for my streaming/off grid nomad setup using my Tesla Model Y. I also got 2 Ecoflow 220w panels and have had no problem running all my appliances and full desktop computer.

I plan to add the extra batteries which has a capacity to expand up to 6kw and a total of 1000W solar input which will be more than enough for my future plans.

GREAT DEAL TOO for the $. Thank you!
