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]

I have one of the Anker batteries. It'll happily take in >1000W from an AC wall outlet to charge fully in ~1hr. It's 300W max DC input from solar (which is where that 3.6hr number comes from) or 100W max from a 12v car adapter.

Those other batteries you linked look like a potentially great deal for raw capacity, though there's something to be said for having a mostly portable package with thermal management and a bunch of different inputs and high-powered outputs.

100Ah 12V LiFePO4 is $218 on aliexpress. https://www.aliexpress.com/item/3256804150747707.html

Ok really dumb question but: how do you plug in a normal plug into a battery like this? I'm nervous about doing it wrong and then frying my musical equipment. The nice thing about the Anker is not having to worry about this.

My friends tried hooking up a car battery to an inverter and something went wrong (not sure what) and they fried 3k of musical equipment.

tl;dr: It isn't totally horrible, but you get what you pay for in this case.

Yeah, as the poster notes, it's not bad. I've had a budget LifePO4 in use for over a year now with no issues. Can report back in 4 more years I suppose.

10 years ago I bought a cheap solar pump (~$100) rather than the standard priced ones at the time (~$1000) I got flack for buying Chinese made goods which were "surely crap". But that pump ran perfectly fine for about 8 years before it started slowing down and running at a reduced capacity.

¯\_(ツ)_/¯

Watch Will's other reviews... not all of them are made well at all.

Based on his reviews and recommendations, I did just purchase a 'cheap' 300ah Chinese battery off of Amazon (AmpereTime) to replace my 3 AGM batteries in my campervan. We will see how well it lasts...
