Capacity of battery (thus far) fails to impress

Perhaps my expectations were a bit too high when I purchased this charger for the purpose of providing a charging backup for my S23, but my experiences to date with this charger are mixed (at best). In reading the info provided by Samsung, it was not immediately obvious this product ships with only one recharging cord (a USB-C to USB-C connection) and not two especially when dual charging capability is mentioned so frequently. Buried a bit deeper, I did find this fact before ordering but making this more obvious in the literature might be a good idea. The same goes with the electrical cord too. I do wish Samsung offered an option while ordering to allow a customer to specify if they wanted 1 or 2 recharge cords and electrical cord.
The performance of this charger to date has been ... okay. My charger was completely without power when received, and took just under 5 hours to receive a full charge. The battery when provided two half charges (each from around 50%) to my S23 before all battery reserve was gone. That cycle has repeated itself (in whole) twice and I am now on the 3rd cycle. To be honest, I expected more charging power (meaning the battery would produce more recharging cycles before requiring a recharge) from this battery and I have yet to attempt two concurrent charges. From this perspective, the battery has been a bit disappointing.
The battery itself seems solid (I have not dropped it yet...) and the display panel on the front of the battery is small but still easy enough to see. The size of this battery makes carrying it in your pocket a bit of a problem but I suspect when I need this battery, I will likely be on longer trips where I carry other bags so putting this battery in another bag should be pretty easy.
No, I would not recommend this to a friend.

Its a nice size and does fast charging , but the lack of a single USB-A port makes it difficult to use for usual use.
I would recommend this to a friend!

Now Samsung...instructions. Yes, I know you are thinking, "Just plug it in to your phone..." That didn't work. I even pressed and held the button. I even "charged" the pack. Nothing. Getting returned.
No, I would not recommend this to a friend.

How do you charge the battery pack?

How do you charge the battery pack if no electrical wall adapter is included in the box? Does it become a paperweight after the battery pack's charge has been depleted?
No, I would not recommend this to a friend.
