How to Know if JBL Go 3 Speaker is Fully Charged

Here, we explain how to know if the JBL Go 3 speaker is fully charged, so that you get maximum playing time from it when you take it outside. But though the unit has no battery gauge per se, you can tell if the battery is at full charge by observing the speaker status lamp as it recharged.  Unfortunately though, we know of no way to determine if the battery actually has full charge without using a charging adapter and USB-C cable.

Now the Go 3 JBL Bluetooth speaker has a single LED on the right side panel, as shown in the following pictures.  This displays battery status, whether it’s draining or charging, or whether it’s critically low or not when discharging.

But this lamp does not show charging progress. E.g. How full the battery is at a given time while charging. Nor does it show how much power remains in the battery when discharging, although it does change color when the battery reaches near-dead state.





How to Know if JBL Go 3 is Fully Charged

1. When the Battery Indicator Lamp is OFF 

When you power down the Go 3 with no charger connected, this lamp, that also doubles as a pilot light, is dark.  Also, with the charger connected, this LED is also dark when the battery has reached fully charged status, as shown next.

2. JBL Go 3 Charging Indicator Shows Battery Recharging Progress

The status lamp lights up red (no flashing) while the speaker charges, as shown in the next photo.  Here, the glowing light is the only visual means to know that charging is going on.  Indeed, the battery is not yet full as long as this lamp glows red with a charging cord connected.
