Follow these JBL Xtreme charging instructions for convenient recharging of this Bluetooth speaker via its hidden DC input charging port, discussed below.
JBL Xtreme Charging Instructions Summary
In short, first, we recommend recharging the Xtreme with the included JBL charger. Why? Because this charger meets the speaker’s current requirements and is provided by JBL. Presumably, JBL feels that this is a well-matched charger since they include it with the speaker. So, we won’t buck any systems here, although in a pinch, you could fully charge the Xtreme with other non JBL wall chargers. But we won’t explore those possibilities here.
It’s time to recharge the Xtreme when the battery status gauge shows a single flashing red light, as shown in the next picture.
When you see the blinking red lamp, connect the black barrel DC output jack included with the speaker between the Xtreme and that power adapter. Then, plug the adapter into a working wall outlet in order to recharge the speaker to full.
Finally after a few hours, your JBL Xtreme speaker fully recharges. Then, you’ll be able to play it again for roughly fifteen hours before you have to charge it again.
JBL Xtreme Charging Instructions, Step-by-Step
1. For Best Results, Use the Included Power Adapter
As mentioned above, we’re using the JBL wall charger AC adapter included with the JBL Xtreme, as shown next.
2. Open the Port Cover on the JBL Xtreme Speaker
Grasp the orange zipper on the lower back of the Xtreem, and pull it to the left, opening port cover. This exposes the USB power out and charging input port inside, as shown next.
3. Plug in the DC Power Cord to the JBL Xtreme
Then, plug the barrel connector end of the wall adapter’s charge cord into the matching DC input port on the speaker, as shown next.
5. Plug the AC Power Adapter into a Working Wall Outlet
Now that the Xtreme and the JBL AC adapter are connected, we plug the charger into a functioning AC outlet, as shown next.
At least one of the battery status lamps lights up on the Xtreme when you apply DC input power. There are five lamps on this Xtreme speaker that light in succession as internal battery charging progresses.
6. Allow the JBL Xtreme to Charge Until All Battery Power Lights Go Off
Battery charging is almost complete when all but the last of the battery status lights light solid. The last one continues to blink for several minutes more to top off the charge, as shown next.
The battery recharge cycle finishes when all battery status gauge lights go out, as shown next.
7. Unplug the DC Charging Cable from the Xtreme JBL Speaker
The next picture shows the round charging port on the Xtreme after we removed the charge cord.
8. Fully Zip Up the Water Resistant Port Door
Note that unless this power port opening flap is zipped completely closed, water could enter the input and output connector ports area, and likely damage the Xtreme speaker components inside. So, take special care to completely zip the port door closed on this speaker, to get full water resistance protection while not charging.
See how this port door looks when fully closed and sealed in the next picture.
9. Charging JBL Xtreme Bluetooth Speaker Done!
We have now fully charged our JBL Xtreme portable Bluetooth speaker. Note that the battery charge status gauge just after turning on the Xtreme after a full recharge. All lamps are aglow, meaning that the speaker is current fully charged, as shown in the next picture.
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.

What Does the JBL Xtreme Red Light Flashing Mean?
When you see the red light blinking on the Xtreme’s battery level gauge, this means that the battery has very little charge left, and that the speaker will shut off within an hour if not recharged. See the red light we’re talking in the last picture above, pointed out by the green arrow. Note though that this lamp never flashes red with a correctly working charger connected and powered on. As you recharge the Xtreme from a completely dead state, this lamp blinks white.
