Super capacitor bank with protection board on Ebay: Is it a charge controller as well?

I am not an electronic person. I came across this 6 cap 2.7V 500F power bank with protection board on Ebay.

As it usually is with these China stuff, there is not much technical info given, not even a circuit diagram. I was wondering if this also acts as the charge controller? Or will it require a separate charge controller / balancer/ charge voltage - amp controller? Thanks.

The text in the ad is essentially worthless. It seems to me that the board ought to at least manage the balancing. It would be kind of pointless otherwise.

What else does it do? Maybe someone can identify the circuitry:
