For what it's worth, I got to test Anker PowerCore 20100 A1271 with iPods Mini A1051 and Video A1136 (2005 "fifth generation", thin "30GB"). This power pack (Anker PowerCore 20100 A1271) supplies both iPods, like one should expect of a regulated power supply. It Just Works, sans 'pushing the charge indicator button'.
For what it's worth I have an Anker PowerCore 20100 and also PowerCore 13000.
Neither one of these send a charge to my 6th gen iPod Classic even after pushing the charge indicator button on the power bank
I wonder if you need to use a particular type of cord?
Manually waking the Anker bank, 'hitting the indicator button to get it charging', is not documented functionality. No, you do not need to acquire yet another cord. Unfortunately, your two PowerCores are not right for your use case. You can try adding a burden load, that might "get it rolling".
Good news to Anker loyalists: almost one year ago (around July 2018), Anker introduced 'trickle' mode. This is a fundamental feature, inherent to power banks which use a "hard on/off" slider switch. Unlike the "Universal Optimized PowerIQ VoltageBoost" marketroid nonsense, Anker's 'trickle' mode should remain engaged until either its battery is drained flat or intentionally disengaged by operator.
These following Anker banks feature 'trickle' mode, so
should Just Work with iPods Nano and Classic (sixth and seventh generations). Anker did not add their disclaimer «except for the iPod nano, iPod Classic, HP TouchPad, Dell Venue 11 Pro, Asus tablets and some GPS and Bluetooth devices.» to descriptions of these products.

I do not like, endorse, recommend, nor promote, Anker or its wares. I feel dirty here, like an advertiser, referring to these products. But knowing that my list is incomplete, I feel compelled to supplement it.
Also these following Anker banks feature 'trickle-charging mode', so
should Just Work with iPods Classic.
