Best praise vs top criticism for EcoFlow DELTA 2
Best Praise
+52 pts“A shame that the original post has gone, but I'll share my experiences anyway. I used to own an Ecoflow Delta 2 for my log cabin which I loved - it worked really well with about 1.8kW power delivery (could boil a travel kettle using it), but I found that it wasn't quite enough capacity to last a full weekend. We had a 50W coolbox attached to it, and it would be flat after a day. One thing you've got to realize is that the capacity that the manufacturer says you're getting is not what you actually get - this is because the inverter, display and fans all take energy, and in fact the useable amount of capacity on the Delta 2 was only about 800Wh. Talking of fans - the fans on the Delta 2 were REALLY loud, and that was one reason I decided to sell it. About 6 months ago I upgraded to an Anker power station (it's the Solix F2000 for anyone who's interested). It's got the all important Li-Po battery tech and a much more chunky 2048Why of capacity - (of which about 1700Wh is useable). I've coupled this with some solar powers and can now last almost indefinitely on free solar if I'm reasonably careful with what I use through the day. Overall I'd definitely recommend these things but they're not cheap - make sure you get a decent warranty - most of the big players are offering 5 years now as standard. I've not had any technical problems with either manufacturer though to be fair - hopefully it'll last me a long time!”

+2 pts“I have the EcoFlow River 3. It is great for running an LED light or two during a power outage. However, charging a couple phones and tablets knocked the battery down significantly. River was dead after second charging of all devices. I feel you will be greatly disappointed in its performance running those appliances on it.”
