How to Charge JBL Go 2

This piece covers how to charge the JBL Go 2 Bluetooth speaker. Do this simply through the USB power in port, behind the water resistant door. Here, we detail this charging procedure for these tiny beach ready waterproof speakers. Note that you can still play your Go 2 as it charges.

First, pick a strong enough USB power adapter, as no charger comes with this speaker. Most any USB adapter should do though, since this speaker only requires around 2.5 watts (5 volts at 0.5 amps).

Next, connect a micro USB charge cable between the speaker and that adapter. Then, plug the charger into a working wall receptacle.

Then after a few hours, your speaker finishes charging. So it’s ready to play once more for up to four hours before needing another recharge.

How to Charge JBL Go 2: Step by Step

1. Choose Correct Size AC or Car Adapter

We’re charging our JBL Go 2 with the iClever IC-TC02 24 watt dual port USB AC charger adapter. Please see our iClever Dual USB Wall Charger IC-TC02 Review post for more details on this excellent USB AC charger.

Now this speaker needs 5 volts at roughly 0.6 amps to recharge fully in the shortest time. So this adapter outputs plenty enough current to juice up these speakers, with lots of time left over.

2. Open the Port Cover on the Speaker

Use a fingernail, dime, penny, or small screwdriver to work open the waterproof seal port cover on the Go 2. See the closed power port door in the next picture. Be careful not to mar the delicate seal around the inside edge of the door.

3. Power Off the Speaker

Note that the Go 2 still charges when energized. But depending on how much above-and-beyond recharging capacity your charger delivers, it might charge faster when turned OFF.

4. Plug in the Micro USB Cord to the Speaker to Continue with How to Charge JBL Go 2

Then, plug the small end of your micro USB charge cable into the matching micro USB port.

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 24 Watt USB AC adapter.

6. Plug the USB Adapter into a Functioning Wall Receptacle

Now that we connected the speaker and USB adapter, we then plug the RavPower into a working AC outlet.

The status lamp then lights up solid red. And while no battery status gauge shows percentage of charge, the glowing light means that charging is occurring.

7. Let the JBL Go 2 Charge Until the Red Light Goes Out

Full battery charging completes when the red lamp turns off.

The speaker now has fully charge, powered OFF, but still connected to charger. The status lamp is dark.

9. Fully Close the Waterproof USB Port Door

Note that unless you snap the port flap securely, water may soak its USB port. And, since water and electronics generally do not mix, getting the USB charging port wet might damage them. So be sure to press the door closed with enough force to seat it correctly.

10. Done with How to Charge JBL Go 2 !

Finally we have now fully charged our JBL Go 2 speaker. But repeat this charging every three to four hours of play. Why? Because doing so helps keep the battery in top working condition for many years to come.
