The other thing is that you shouldn't get fixated on Anker. There are others who could help. I have a few RAVPower chargers that I got before they were turfed off Amazon for buying ratings and they're fine. Aukey cables, same thing. But setting aside buying ratings, they did work. I can't vouch for how they are now, but I'd be willing to give them a shot for their power banks. You may need to get some better cables, but might give you some additional leeway in product selection.
