The battery supplies 220V/50Hz/80W. In theory, you should be able to charge/operate anything that can be operated from a normal mains supply and does not require more than 80W.

I connected it briefly to my Shimano Steps E8000 battery (BT-E8010) and it charged (from the display). However, you would only get 1/6 of the battery charged (504Wh for BT-E8010, 84Wh for AL480N) without any loss of efficiency, and this will also take time.
