Model A3390V , Rave Mini is A3390. The name of the product is not in the FCC listing but is shown on the label, so my guess is it is either called actual Rave Partycast, or is a variation of the Rave / Rave Mini.
From what I understand Rave Mini doesn’t have PartyCast enabled (think because of hardware limitations). The new speakers will have PartyCast technology and the “PartyCast” name. Had a thread about this on Soundcore community
