How to Charge JBL Xtreme 2

Here’s how to charge JBL Xtreme 2 portable Bluetooth speaker through its  protected DC input power port and the included 19 volt power adapter.  Follow these tips, and you’ll likely never see that the speaker won’t charge.  If all components are working properly, it will always charge.

How to Charge JBL Xtreme 2: Summary

In short, first, we recommend that you charge this speaker with the included JBL charger. Why? Because this charger meets the speaker’s current needs, and is provided by JBL besides.  Presumably, JBL thinks that this is a well-matched charger.  After all, they do package it with the Xtreme 2.  So, we won’t buck any systems here, and will indeed use that charger. But in a bind, you could fully charge the JBL Xtreme 2 with other vendors’ wall chargers.  But we won’t discuss those options here.

Now, it’s time to charge this speaker when the battery status gauge shows a single flashing red light. See the location of the speaker’s battery indicator gauge in the next picture.

When this gauge shows a single blinking LED, plug the black barrel DC output charge cord jack into the speaker. Then, plug the charger into a working wall outlet. Don’t worry though about having to wait for the speaker to fully recharge before you can play it again.  The JBL Xtreme 2 will indeed play while charging, although it might take slightly longer to charge when played at high volumes.

Finally after a few hours, the speaker fully charges. Then, play it for roughly fifteen hours before you have to charge it again.

2. Open the Speaker Charging Port Cover 

Stick a coin or blunt straight screwdriver into the slot at the top of the port door, and pry it open. This exposes the USB power out and charging port inside, as shown next.

At least one of the battery status lamps lights on the speaker when everything is working correctly. Five lamps on this speaker light in succession as battery charge progresses.





5. Allow the JBL Xtreme 2 to Charge Until All Battery Power Lights Go Out

Battery charging is almost done when only the last of the battery status lights light is blinking. The last then blinks for several minutes more to top off the charge, as shown next.

7. Next, Snap Closed the Port Door

Note that unless you fully close this door, water might enter the connector area.  It could then damage the electronic components inside. So, take great care to fully close this port door to get the fullest water resistance.

See how this port door looks when fully closed and sealed in the next picture.

8. Done with How to Charge JBL Xtreme 2 !

We have now fully charged our JBL Xtreme 2 portable Bluetooth speaker. Note that the battery charge status gauge just after turning on the speaker after a full recharge. All lamps glow, meaning that the speaker is fully charged.

Repeat this process every fifteen hours of music play to keep its battery in good condition. We charge ours when the battery status gauge lights show just one lamp glowing.
