It does also support Samsung "Super fast charging 2.0" so we can quick charge our phones from it.

but yes they should probably have choosen a better name.

the baseus power bank maxes out at 65w input so recharging the power bank is a slower process. i travel somewhat frequently so being able to fast charge is a pretty big boon and this cuktech 15 ultra has a "beast mode" (up to 165w max input using 2 USB-C inputs)
i'm also guilty of buying more power banks and chargers than any sane person could ever need and while i don't have this 15 ultra, i do have the smaller 10k mAh cuktech 10 and am really happy with it. cuktech power banks that support fast self-recharge usually do so at significantly better value than alternatives like Anker or UGREEN and i've been happy with what i've seen in teardowns so far. for reference, both the cuktech 10 and this cuktech 15 ultra uses EVE 25P 18650 cells
the cuktech 10 is inscribed with 4INR19/66 on its side (4S1P) and after confirming with some amazon and reddit reviews for pics, the 15 ultra is just 4INR19/66-2 (4S2P). this does mean they're pushing the 25P cells harder than what they're rated for, but this isn't new and is common across what Anker, UGREEN, and Baseus do for their power banks and cells. it's why most power banks throttle and cut output. IME, the cuktech 10 is able to sustain max output during its full discharge cycle, but it isn't able to sustain its max 90w input for the full charge cycle (usually drops to 45w input at around the 60% SoC mark). knowing this, i wouldn't be surprised if this 15 ultra also isn't able to sustain it's max 165w input the full recharge cycle. to be fair, my cuktech 10 actually has a better charge and discharge curve than some Anker and competitor power banks. check out AllThingsOnePlace's reviews of power banks to get a better idea: https://www.youtube.com/@AllThingsOnePl
more random info do what you will with this: cuktech is part of ZMI (a Xiaomi subsidiary) and they supply white label power banks and charging equipment to OEMs like Xiaomi, LG, Hitachi, etc... and are reputable / well-known in Asia
also worth noting that EVE cells are considered reliable / high-quality, but not quite on the same level as Samsung or Panasonic cells
