I don't get it are you looking for something similar to this?

There is https://www.amazon.com/dp/B01M11UT3V/ref=cm_sw_r_cp_apa_i_LTyaBb3D8DDEF

but no included battery pack.

The conversation below and I both have the impression you wanted this exact device- if so, no, it won't work.

if you want something similar, google (or amazon) moto x4 wireless charging cause that's what I just did and found a shit load of product hits. But I don't see any with an included battery.
