Reviews
JBL Battery 400 for PartyBox Stage 320/Xtreme 4 - Black (JBLBATTERY400) is rated 2.0 out of 5 by 2.
Rated 3 out of 5 by from Needs a charger The idea of having a second battery is great. However, JBL so far has missed big by not having an option to charge the spare battery when it is not in the speaker. Would be an easy fix to make a standalone battery charger.

Rated 1 out of 5 by from No excellent features So stupid why can't u charge it without it being in the speaker why doesn't it have USB c or u at least sell a charging dock it's literally pointless to have this battery
