I purchased this about a mouth ago and have yet to use in a power outage. I have tested it on my refrigerator and freezer which worked fine. The flaw is it will not run my natural gas fired boiler that heats my house. From what I researched I found that it needs a pure sine wave AC current and the Delta 2 output is a modified sine wave. I have yet to find a cost efficient solution to this issue.

Recently I purchased from EcoFlow, a Delta 2 generator, 2 100-watt panels and a portable 220-watt solar panel kit, plus necessary cables and accessories. The purpose of the system is to power an off-grid art studio. Several years earlier, I purchased a JACKERY system, but it lacked the capacity for this project. After much research and studying numerous reviews, I chose the EcoFlow system. Not only were their products highly rated, they are state of the art, efficient, and customer service was excellent. Choosing all EcoFlow products made designing the project easy. All parts of the system are of highest quality and most important, compatible with one another. This simplified creating the system, prevented error, and enhanced safety. This project is a work in progress. EcoFlow’s excellent design allows expansion of the system with additional panels and storage batteries. All of the additional components are compatible and ‘plug & play’, making the system very flexible and easy to adapt to various needs. By adding the folding 220-watt solar panels to the very light Delta 2 generator, it becomes not only a portable system but extremely versatile. I’m very impressed and pleased with the design and quality of the products, their efficiency, expandability and ease of use. I look forward to working with it and recommend EcoFlow products without reservation. The 2-year warranty is also comforting.

We bought the Delta 2 and the 110 watt solar panel for emergency backup and to also power our new Iceco Go20 for when we are camping. The Delta 2 can run the Iceco Go20 for a little over 3 days before it needs to be recharged. It has enough power to run a standard electric coffee maker and a Keurig coffee maker. When using household power to recharge, it usually takes less than an hour to recharge the unit. We recently bought another Delta 2 and 220 watt solar panel to add to our capacity. The app for the Delta 2 is awesome.

Purchased about a month ago after extensive research. Delta 2 and Smart Extra Battery arrived but would not communicate with each other. Email to customer service and they immediately sent a new cable. Cable arrived in 5 working days. Hooked up perfectly, charged rapidly..1.5 hours to charge from 30% to 100%. Ran cPap for three nights before needing a recharge. Tested three times with same results. Cpap has a heated reservoir and heated tubing. Based on past experience, disabling these functions will cut energy consumption in half.

I've been waiting for this soon as i got this i had to try it so i charged just something to use to to save food in my freezer and refrigerator from full charge i powered my fridge,tv,routers,and charged phones 6hrs np i know there's more out there but this works for me im simple, price was right i already had panels im not real technical this will be fine

Customer service is easily accessible. Product is 85% perfect. Reasons for 4 vs 5 stars below: 1. It needs a larger 12 volt Connection, over the 12v. 10 amp provided, (at least one 10 amp @ 13.5v. and two 15 amp @ 13.5v). 2. The Cooling fan is unnecessarily WAY TOO LOUD. It is controlled by charge or discharge wattage. It should be temperature controlled and redesigned to be quieter on its highest setting. 3. The Auxiliary battery should be connected in the back like all the other connections. Plus the auxiliary battery wire is too thick and stiff. Please don't BS me and say it needs to be that way.

So far I am loving this sogen. Runs my microwave, and air fryer with no problems. Vacuum cleaner with full power. Tv,router, Roku, washing machine, all without a problem. Tomorrow will hookup pv 400 watts and see how that goes, but so far I am pleased.

The January 2023 rains here in California were brutal. I tried to expedite a battery from EcoFlow…and they came through! When the power outage hit..this battery kept a few lights on and powered all our devices. It even powered our Dyson heater. The ExoFlow Delta 2 was amazing.

I did buy this Echoflow Delta 2 about a month ago. I have used it once so far. I use it primarily for electrical power for my telescope guiding mount and camera. The unit has DC ports and regular plugin grounded outlets so it works great powering my hobby.

I have another unit from a different manufacturer. Same size. The Delta is crazy efficient with solar charge. Charging at 200w where my other unit is 140 w. And. The Delta can go to 500w charge. Crazy. Charges in almost half the time. In all other ways it's comparable. But charge time is key when you have your appliances plugged in and you want to keep them running while charging. Very nice unit. Love the Delta 2. Would like a less expensive option for a second battery. But what you gonna do.
