It's kind of hard to get that excited about the Anker given price to storage ratio. It's a fancy wrapper around a 100AH LiFePO4 battery. You can get a decent LifePO4 battery now for $399 [1]. I'm not sure the wrapper they have put around it is really worth the extra $1000 (total $1399, at least on Amazon). It's also weird their marketing material says charge to 80% in 1 hour [2] when it has a 300W max. (On Amazon, looks like it is actually 3.6 hours to 80%) [3]
