Setting this up today and found that the accessory station needs an adaptor to charge the spare battery we received per the manual:
VS20A958*** model: To charge the battery at the Accessory Cradle, a charger needs to be purchased separately. (VCA-SAPA95)
But can I find this anywhere? Nope. The only thing I see online is this, which appears to be another battery...any ideas?
Spare battery should come with charger cable... https://www.samsung.com/au/home-appliance-accessories/bespoke-jet-accessory-cradle-battery-adaptor-v...
