Whew!!! 3KW hours of power now...

Excited to now have over 3KW hours of power (this plus extra battery plus two 500 WH power stations I already owned) along with solar panels dedicated to each of the three power stations. Not enough to run my whole house; but, certainly makes me feel better to know I can run the fridge and furnace if needed for a day or more (not counting solar recharging).

As expected 🎈

October 2022 purchase. Charging from 200 watt fixed solar panels off grid. Purchased EcoFlow adapter. I have used a 1500 watt water kettle, induction cook top, and 12volt cooler 24/7. So far so good but if there are any issues I hope the company has options for repairs in California.

Best in Class

Delta 2 is best in 500-1500Ah range. Made my second purchase of Delta 2. First was for my daughter for camping. This one's for me. Incredibly fast charge time. LiFePO4 gives you long cycle life. Best price performer. EcoFlow has great tech support and backs it up with 60-month warranty.

Hurricane back up power.

During hurricane Ian we had no power and no cable service and could not watch what was happening around us. Since then I bought an antenna to hook to a tv but knew I would not run generator till storm was over. EcoFlow DELTA 2 solves power problem I ran TV for 2 days to test and it worked great.

Delta 2 Backup System

This setup is used to power our refrigerator and freezer during power outages. The Delta 2 and extra battery is charged with an EcoFlow 160 watt panel and/or a propane powered generator AC port. The Delta 2 is easy to manage through the app and I hope to purchase an additional solar 160 watt solar panel and an EcoFlow Smart bi-fuel generator to supplement our setup.

Love my Delta 2

I live in New England and it is possible that we will have rolling black outs this winter which is why we purchased the Delta 2. A wind storm this week knocked over a tree and we were without power for several hours. I was able to hook up lights, my computer, and monitor, my warming throw blanket over my lap and use my phones personal hotspot. This enabled me to continue working. My husband also hooked up our Kerug so we could enjoy some coffee.

Reliable Power Solution During Extreme Weather

I purchased the Delta 2 generator one month ago, and it was put to the test during a recent storm with 90 mph straight-line winds in Omaha. That evening, 216,000 people lost power. I was able to connect our fridge, laptop, and phones to the Delta 2. We also have the smaller River version, which we used to power two large fans so we could get some sleep. Even after 14 hours, the DELTA 2 was still running my fridge! While everyone in the city was concerned about losing their groceries, I felt at peace knowing that even if the power didn't come back on for the next seven days, as predicted by the power company, I could recharge the generator with solar power in a couple of hours and reconnect my fridge. Later that day, our power was restored, and I lent the DELTA 2 to a co-worker who was still without electricity. He was incredibly impressed by the ingenuity of this product. I am proud to have been prepared and felt a sense of peace knowing we would get through the storm's aftermath safely.

I am very happy with the flexibility of the Unit

I have a Kia Niro plugging hybrid and I have been wanting, for a long time to put solar panels on the top of it and charge the main battery, with your products I’ve been able to set up two solar panel units that are 160 W each. And here is the magic: I can charge the Delta unit with the panels and the car main battery with the Delta unit at the same time!!!

Just as described

Received the Delta pro 2 unit in a timely manner. It was well packaged so no damage in shipping. Easy to set up and seems to function exactly as described. I may find that we will be lacking some capacity if we have extended power outage however that’s not a short coming of the product and can be rectified by adding an additional battery.

Not a UPS for keeping your PC running

This is not a UPS (uninterruptible power supply) system. It does work well as a power source, but if you want it to keep your pc running when the power goes out...it does not...when the power goes out the back up power takes over, but the split second during the switch powers down your pc...so not a good choice for keeping your pc running contiuously during power outages.
