Standard price for goal zero yeti is $40 cheaper, same capacity (https://www.amazon.com/Goal-Zero-Portable-Station-Generator/dp/B00D5RVMAM)
It’s sold by Amazon, so it comes with free returns/replacements by Amazon’s customer service, which is much more flexible when selling first party. It has a 2nd AC output, and has been on sale twice at $300 in the past year (https://camelcamelcamel.com/Goal-Zero-Portable-Station-Generator/product/B00D5RVMAM) The Yeti also has expandability with the optional solar panels that you can add on to charge it with + the build quality just seems much more durable.
Meanwhile, the Powerhouse as a single AC output, less info on the display, only 1 AC output, a higher price, and doesn’t come with Amazon’s customer service/ease of returns and a free snack. To be fair, the powerhouse did drop to $329.99 for a day in May of this year.
TL;DR Anker needs to step up its game to be competitive and make the powerhouse appealing in any way at all.
