Disassemble JBL Partybox 100 & Battery Upgrade (Part 2/2)

This video explains possible JBL Partybox 100 upgrade solutions and guides you through the one with an external power bank. The advantage of using the external power bank upgrade is that it's the least destructive (beside drilling a hole in the sidewall), allows you to run the speaker in performance mode (thanks to the 20V power bank power source) and charge the 20V power bank with another, common lower voltage power bank for an extended duration. Items used in this video for the external power bank upgrades (Affiliate Links): It might be very likely that you already own several of the above-mentioned items. For me, this upgrade cost me around 75€ Note: I'm not a professional, not affiliated with JBL, every action you perform are your own risks and I'm not liable!
