+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!”

+10 pts“Literally just came out of a 5 day blackout due to an ice storm. We have the ecoflow river 2 pro and it was worth its weight in gold. We have a gas generator that we run twice a day for the fridge and freezer. We'd also do kettles if hot water for dishes and we would recharge our ecoflow then too. So why was it so great? We could power a kettle midday for coffee and tea without having to fire up the generator. It charged our phones, flashlights and my father in law's electric razor (just because he needed to shave). It powered the blower on our woodstove as the temperatures up here were still around freezing. And lastly we used it to power a crockpot to heat up food. It was absolutely amazing and fantastic for the in between times of running the generator. ”
