Customer Reviews
We bought the Delta 2 after searching and weighing all of our options. EcoFlow seemed like a no brainer compared to the rest of the products available in South Africa. The charge time is great, we use it for our TV (50 inch) our wifi router as well as the work station which has a laptop a second screen and a printer. The 30ms switch time works like a charm, Wi-Fi and TV does not cut out at all and stays switched on. It lasts two hours and still has 60%+- battery left. We will be buying the River 2 to also add to the arsenal which will power our freezer and fridge. Delta 2 is recommended over the Delta 1 as the battery is far better and has 3000+ cycles guarantee on the battery compared to 800 on the Delta 1.
Bought my Ecoflow Delta 2 in May, my wife is very happy! Good quality product and i will buy the Delta Max extra battery soon. Only one issue with the Delta 2, where can I buy the new sans 164-2 plugs that will fit the 2 x plug inlets at the back? I bought 2 x plugs from my local electrical supplier, the pins lign up but is slightly fatter and do not go in.
While EcoFlow has a good name around the world and produces a good product, after purchasing the Delta 2 in South Africa, it is difficult to get support for the product. The delta 2 rated at 1800 watts and 2400 watts on boost, is unable to run the microwave rated at 1350 watts. It only works now and then, running for long periods once going. You never know if it will start up or not. The support team is telling me that the microwave is too big for the Delta 2. That does not make sense and after spending so much money, it should be able to constantly do what it says it can do…. This is very disappointing. Here’s hoping someone will see this and help us.
I love my Delta 2, in fact so much that I bought the Delta 2 Extra battery as well. And with my solar panels hooked up to it, I almost rarely make use of grid power, even when boiling my kettle or using my microwave.
Lasts me an entire night watching TV, 55" or 65", running lights, fridge, electric blankets, bedside lamps, the occasional electric blankets for when it gets REALLY cold as well as my Air Purifier right through the night until my solar can take over again the next morning.
Just wished the Smart Generator would have been compatible with this unit for those emergency, VERY LONG lasting cable theft outages at night.
Ok, so today when I got home at 14:30 Friday 28/07 it's load shedding till 16:30, I have had my Delta 2 for two months just for TV Wi-Fi and a lamp so I decided its time to stress test this unit as I also have a laser engraving business on the side at home... I unplugged the unit and moved it to my workshop (portable right) and have plugged the following in... Sony Bravia Tv, 50W Fiber Laser, Desktop PC, Extractor Fan, Fiber incomer box, Zyxcel Router, network switch, LED strip light, the unit is also supporting two other UPS type devices... to be honest I expected it to give me maybe a half hour runtime with all this stuff going on but NO Ecoflow continues to live up to its well deserved reputation AND wait for it... with all this running it gave me a total runtime of just over 2H36m And yes... I used the fiber laser to mark at the time of measurement... well done Ecoflow on living up to your promise and design standard, if I had been able to add solar to the unit by this time I am almost sure the Delta 2 would not even notice the power draw... my goal will be the flagship from Deltaflow Pro and all the solar bits plus extra battery that goes with it, that would take my business and my home to the next level indeed !! (c'mon Ecoflow... 🤣🤣🤣)
