Best praise vs top criticism for Anker 521 PowerHouse
“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.”
“Anyone but Anker. Seriously one of the worst companies I've had to have dealings with”
What Redditors Say
Best praise vs top criticism for Generac Guardian Series
“I've installed hundreds of generacs. I've had one with a bad board and it wouldn't go into auto, and one that idled more like a Briggs and Stratton unit than a generac (rough and unstable). We have units from 17 years ago still running with yearly maintenance and happy owners”
“Long story short: He had a Generac Home Generator installed about a month ago. However, since it was installed, it has yet to work. Been DOA, dead on arrival, and he had to go through the Hurricane without it. He and others are claiming that this isn't just a "one off" and that Generac is putting out poor quality generators then what they used to.”
