How to Charge JBL Pulse 3 Bluetooth Speaker

This piece covers how to charge the JBL Pulse 3 Bluetooth speaker. Do this simply through the USB power in port on the back. Here, we detail this charging procedure for these party ready wireless speakers. Note that you can still play your Pulse 3 while it charges.





In summary, pick a strong enough USB adapter, as no charger comes with the Pulse 3 speaker.  Also note that while this unit accepts a USB micro plug for recharging, you can use either a USB-A or USB-C charger, so long as you have the right cable to connect the speaker and adapter.  If your charger provides the 5 volts at 2.3 amps (11.5 watts) power level, then it really doesn’t matter whether it’s a USB-A or USB-C power supply.  JBL does include an older style USB-A charger and cable with this speaker.

Next, with all that said, connect your cable between the speaker and that adapter. Then, plug the charger into a working wall outlet.

Finally, after four and a half (4.5) hours, your speaker completes charging.  So it’s ready to play once more for up to twelve (12) hours before needing another recharge.

How to Charge JBL Pulse 3 Speaker

1. Choose Correct Size AC or Car Adapter

In this case, we’re charging our speaker with a Key Power USB charging station, as we picture next.

Now as mentioned earlier, the Pulse 3 needs 5 volts at 2.3 amps to recharge fully in the specified time.  So this adapter outputs plenty enough current to do this job well.

Find this USB-C charging port on the left side panel, beside the carrying loop, as shown next, pointed at by the yellow arrow.

The battery gauge lights up blinking white when the speaker receives power from the adapter.

Now if you don’t see this meter start flashing, then either you speaker is already at full charge, or either your speaker, cable, charger, or wall outlet are defective.  Troubleshoot each of these in turn to isolate and fix the problem.

7. Let the JBL Pulse 3 Charge Until the Battery Gauge Stops Blinking

Full battery charging completes when the speaker’s the battery meter shows all lamps glowing steadily, as we see next.
