Amp Hours (Ah) is not a cross platform measurement of capacity. 5Ah for your phone is likely at a different voltage than the 2.6Ah LPe6 battery.
Amps*Volts=Watts
Watt hours is a true measurement of capacity because you can extrapolate the amps and volts.
What I use is an NPf 970 battery on a Blindspot plate with a 12v dc out to weipu 2 pin cable.
Companies get cute with what they quote as the "MAh capacity" of a given battery, but the Sony standard for a 970 battery is 6600MAh at 7.4v I believe, which is 48.84 Wh. I haven't really seen truly higher capacities than that despite what manufacturers say.
The Pocket 4k draws *roughly* ~25Wh of power (from my tests), depending on screen brightness, codec, frame rate, and attached accessories. So one of those batteries gets you perhaps up to 2 hours if you're lucky. If you need endurance longer than that, I HIGHLY recommend getting a VMount or Gold Mount battery instead of a battery bank, because it will allow you to expand to other cameras and lights in the future and they will provide much more power. You can get VMount batteries that go up to roughly 100Wh. These are professional cinema batteries the industry standard.
NPF batteries allow you to power other things like lights and monitors as well, plus they are small enough to gimbal mount or go handheld if you need to. Banks and VMount will be larger and heavier. That is why I chose NPF.

Why not buy an actual adapter that is made for a single f-mount battery to USB then? Besides the price? Sorry, I just refuse to condone cobbling together crap to make it work when there is an actual product for the purpose.
Or buy a D-tap converter that changes the V-mouny to D-tap, then you can get a D-tap to USB to plug in to that.
