Three questions frame an accessory order before you even look at part numbers.
Which model exactly? The TC22, TC27, TC22R and RFD40 do not share cradles or cables. Only the 7000 mAh battery and the 4-slot charger are common to the RFD40 and the TC22R.
How many units to charge? Below three devices, a single-bay cradle is enough. Above that, a multi-bay cradle with its power brick cuts both the footprint and the number of wall sockets.
Charging only, or charging and transfer? A cradle charges; a USB-C cable adds synchronisation with the workstation.
