By "the original," do you mean 521 PowerCore Magnetic 5K? It supports 10W USB-C output.
Anker’s 521 PowerCore Magnetic 5K was one of the first to be released…
Anker makes one. Just got it today and I’m quite happy with its size and weight for a 5,000 mAh MagSafe battery pack.

I got this Anker it’s about right under the size of a deck of cards and in some way I feel like it can make the phone easier to hold.
I recently bought the Anker power bank and relatively enjoy it when I need it. I would have liked to have more mAh for the price, but convenience has its price. https://www.amazon.com/dp/B08TW7BRTJ/ref=cm_sw_r_cp_api_glt_fabc_4YGBXAHW0WRRN63YKMM6?_encoding=UTF8&psc=1
