Cheapest offer

Keep the party going by having a spare JBL Battery 600 with charging case on hand. Just insert it into the battery slot in the back of your JBL PartyBox 520 when the first one loses its charge. It also can replace the rechargeable battery inside a JBL Boombox 4 portable speaker when it starts to degrade. The JBL Battery 600 with charge case doubles as a powerbank to charge your tablet, laptop or smartphone* with the convenient USB-C port on the charging case. (*charging cable not included) The JBL Battery 600 is only compatible with the JBL PartyBox 520 and Boombox 4. Other speakers in the JBL PartyBox and Portable series have different battery requirements.
