Review on Portable acoustics JBL Charge 4, 30 W, blue by Boyan Slavchev ᠌

It seems to me that it would be more beneficial to pay the additional cost for charge 4 rather than purchase charge 3. (picture to prove that I own it) I also recently learned that newer models have a different connection (called party boost rather than connect +). This indicates that it can only link to older columns; connections to more recent ones are prohibited. (this is the most recent model, and it comes equipped with conect+)
