This piece covers how to charge the JBL Go 3 Bluetooth speaker. Do this simply through the USB power in port on the right side panel. Here, we detail this charging procedure for these mini beach ready waterproof speakers. Note that you can still play your Go 3 while it charges.
In summary, pick a strong enough USB charger adapter, as no charger comes with the Go 3 speaker. Also note that while this unit accepts a USB type C plug for charging, you do not necessarily need a USB-C charger. Indeed, you may use older chargers with USB-A style plugs, so long as they provide the 5 volts at 1 amp (5 watt) power level, and you have a USB-C to USB-A cable. JBL includes one such cable with this speaker.
Next, connect your cable between the speaker and that adapter. Then, plug the charger into a working wall outlet.
Finally, after a few hours, your JBL Go 3 finishes charging. So it’s ready to play once more for up to five hours before needing another recharge.
How to Charge JBL Go 3 Bluetooth Speaker
1. Choose Correctly Sized AC or Car Adapter
In this case, we’re charging our speaker with an iClever dual port USB AC charger adapter, as shown next. Please see our iClever Dual USB Wall Charger IC-TC02 Review post for more details on this excellent USB AC charger.
Now as mentioned earlier, the Go 3 needs 5 volts at roughly 1.0 amps to recharge fully in the specified time of 2.5 hours. Thus this adapter outputs plenty enough current to do this job well.

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

3. Power Off your Go 3 JBL Speaker (Optional)
Note that the Go3 still charges when energized, when powered ON or OFF.

But depending on how much above-and-beyond recharging capacity your charger delivers, The speaker might charge faster when turned OFF, especially when using lower current chargers.
4. Plug in the USB-C Cord to the Speaker to Continue with How to Charge JBL Go 3
Then, plug the mating end of your USB-C charge cable into the matching port on the speaker, as displayed in the next shot.

5. Plug the Other End of the USB Cable into your Charger Adapter
Next, connect the A end of the USB power cable to the power adapter. In this demo, as said earlier, we’re using an iClever USB AC adapter along with the cord that came with this speaker.
6. Plug the USB Adapter into a Working Wall Receptacle
Now that we connected the JBL Go 3 and our USB charger, we then plug the adapter into a working AC outlet, as shown next.

The status lamp lights up solid red on the speaker when it receives power from the adapter. And while no battery status gauge shows percentage of charge, the solid red lamp (no flashing) means that charging is occurring.
Now if you don’t see the red light come on, 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 track down and correct the problem.
7. Let the JBL Go 3 Charge Until the Red Light Goes Out
Full battery charging completes when the speaker’s status lamp turns off, as shown next.
