From the listing, it seems to use the "pouch" type of battery cells that newer / smaller power banks use (INIU comes to mind). However, based on the reviews of all those pouch type cell power banks, longevity is really a concern.
I bought this 2-3 months ago which has a higher capacity, cylindrical cells, but less total wattage output (but still 140W max single output): https://slickdeals.net/f/19011964
That deal still seems to be live, but the units has some caveats. Please see the thread for my comments. YMMV.

Exceptionally bland power bank compared to others with similar designs. Cannot negotiate with a oneplus charger to take a reasonable fast charge. Tops out at around 9v and 5 amps for a steady 45w with the oneplus 15. Seems a little light weight for the stated capacity.
