Portable power station in a shed?

I'm planning to purchase a power station for my shed. My budget is $1,500-2,000. Since I'll use it both in the shed and as backup power during outages, mobility is important to me (I'm over 50 and need something that's easy to move around).

I'm torn between Anker Solix F3800 ($1,999) and Bluetti Elite 400 ($1,499). Both have 3840Wh. The F3800 looks better on paper, but the price is a bit steep. The Elite 400 meets my needs spec-wise and the price is right. My only concern is that it's a new released product and I'm not sure about bluetti.

Any suggestions? TIA!
