How to Charge JBL Pulse 3 Bluetooth Speaker

The JBL Pulse 3 speaker connected to AC Power and charging.

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 this unit accepts a USB micro plug for recharging. But you can use either a USB-A or USB-C charger. Thats so long as you have the right cable to connect the speaker and adapter.

Now perhaps your charger provides the 5 volts at 2.3 amps (11.5 watts) power level. If so, then it really doesn’t matter whether it’s a USB-A or USB-C power supply. Indeed 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.
