This looks almost exactly similar to the Anker Prime (if I’m not mistaken, the 737 model). I wonder if they have the same manufacturer (if they both white-label this product). Otherwise, I'll wait for other reviewers, like ChargerLab, for a review and teardown of the components.
I personally use Anker prime, which is 99.54 watt hours. I needed something to max the regulations and also charge a laptop at the same time. But I won’t stop myself recommending these power banks. Someone may only want this size, whilst I’m a maxerouter.
