Anker 521 PowerHouse vs EcoFlow DELTA 2

“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!”

“Wife and I each have one of [THESE](https://www.anker.com/products/a1695-anker-power-bank-25000mah-165w?variant=44320657997974&ref=power-banks) from Anker (best battery backup I've ever used) and then [THIS](https://www.ecoflow.com/us/river-pro-portable-power-station) big boy from EcoFlow with a couple fold out solar panels. Done us great through multiple trips and power outages. Pretty much my perfect setup, not sure what I could improve if I wanted to beyond more solar for faster charging, maybe another big battery unit (they can daisy chain) but I haven't ran the one I've got dead yet so it's clearly not pressing. We also have [THIS](https://www.bougerv.com/products/crpro30-vip-30-quart-portable-fridge) electric cooler that can plug in or use a 9h battery for camping/travelling/power outages. VERY happy with it's first road trip from Seattle to Vegas and back, when we got home with covid we just plugged it in and our leftovers were still 31f a week later when we felt good enough to unpack.”
