EF ECOFLOW DELTA 2 Portable Power Station Extra Battery, 1kWh Added Capacity for Home Backup Power, Portable Battery to Power Multiple Heavy-Duty Devices

I received this unit just before going on a week long camping trip and figured it out in a day. The only part I've never gotten to work is the app and to be honest I didn't need it. If you review it online you'll find its working 1 in 5 people. Tech support couldn't help me and I will try them again later.The unit work for me in 90-100 degree weather without any issues! I rarely heard the fans running. When I did hear them I was right next to them or I was charging the unit by electrical outlet. I had the solar panels which work if you can get them in full sun. I couldn't because of where I was camping. Shade or direct sun was my choice and I chose shade!The unit powered my CPAP, fan and charged all my electronic devices for 6 days before needing to be recharged. I eventually ran a Keurig on it as well and still had plenty of power available to me. I could've gone the entire trip without recharging the unit, but decided to do it just in case.This unit is heavy and you don't want to drop it on your foot. It's insulated so it won't ground out if left on the ground or in a tent. I found it to be very sturdy and easy to use. I never had it turn off when I was using it. However, if I left it on with nothing running it turned off after 30 minutes which worked for me.I charged it on my balcony when I returned home. The unit comes with a long cord for solar panels. I had enough cord length I could leave the unit inside and the solar panels outside and still have almost 3 feet of cord. The day was cloudy so it took a while to charge. In full direct sun I saw one charge in hours. I would recommend this unit to anyone going camping.We bought this unit because we went to a state park and plugged into the outlet at the site which fried everything! The outlet was bad and ever since we've wanted to free ourselves from the need of electricity and I believe we have found it.

While getting a smoking dealing on prime with the bi-facial panels, it did occur to me that we cant always count on sun and this Tropical Storm Hillary is the perfect example. While Mexico took most of the beating Newsome has declared a state of emergency when he came here to San Diego. As a renter who could not install any solar in this home I was really glad I made the commitment to my newest addition to my preparedness plan. I also got my sister to buy the Delta 2 combo, but will be the shining example for her to upgrade her system with the Delta 2 Max battery. I love the stack ability & AC function. I had only purchased a competitors model on a small scale for my cpap. This was very easy to test my whole home & verify how time I would get from the 2 units. This also educated me on more efficient power cabling of other battery backups I already had for my office pc and Internet equipment. I can still look forward to black friday to another one!

I purchased my Delta 2 Max a few weeks back and have run it through it's paces. The app is simple to use and helpful. Setup was simple and all of the features were easy and intuitive to use. This is a nice addition to my camping setup keeping my tents and car cool in the summer and warm in the winter. I've also got it in an electrically shielded container when in storage in case the worst happens I can get silent power in a crisis. Even when charging, the cooling fans are whisper quiet. You can sleep right next to this unit while it's running and it won't wake you up. The digital display allows me to monitor the watts in and out in real-time from each charging or discharge group and the entire unit seems built to last. Pricey yes, quality yes. For me, it was worth it.

Just purchased my second extra battery to bring me up to over 6000 watts. We live in the mountains and lose power a lot. The Ecoflow solar generator has worked flawlessly for the past year. We power our frig., 60" TV, router, cable modem, cable box, several lights and a large fan if needed from 4:00 PM to 4:00 AM. 4:00 PM is when the higher PGE rates kick in so we avoid that. We also try to recharge all out rechargable electronics on the solar generator. We use a timer to turn the power to the Ecoflow on an off. We also have 2 160 watt panels that keep the batteries topped off during the day. Adding the third battery will allow us to run 24/7, I hope. We also have 2-2000 watt generators which we used recently to regenerate the solar batteries during a 24 hr power outage and overcast skies. Only negative is the noise during recharging. I could solve that by moving the batteries outside but prefer to keep them inside by choice. Not sure if there is an economic justification for Ecoflow but the peace of mind makes it worth it.

Integrates with the Delta Max batteries perfectly. Since getting these, I haven't had another outage yet, but based on previous outage with just the 2 Delta Max, my new setup should give me 48 hours of power for my water pump, hot-water heater and fridge in warmer weather. During winter, probably 24 hours with my furnace in the mix. Can't wait for the next outage to try them out!!

Truly amazing product. I have purchased main unit first and was trying to keep my big 43' Fifth Wheel running off grid, but soon realize I needed more power. I add two more batteries for total of 6016Wh.Fully charged I can run my full size refrigerator, make coffee, run microwave for almost 16hrs without needing to recharge.

Very happy with our purchase. The customer service, shipping and quality are at the top with this brand.We bought it to expand the power of our ecoflow delta max 2000 battery, and it really worth it !
