Follow these JBL Xtreme charging instructions for convenient recharging of this Bluetooth speaker.
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. But in a pinch, you could fully charge the Xtreme with other non JBL wall chargers.
It’s time to recharge the Xtreme when the battery status gauge shows a single flashing red light.
When you see the blinking red lamp, connect the power adapter. Then, plug the adapter into a working wall outlet.
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.
As mentioned above, we’re using the JBL wall charger AC adapter included with the Xtreme,.
Grasp the orange zipper on the lower back of the Xtreme. Then pull it to the left. This exposes the USB power out and charging input port inside.
Then, plug the barrel connector end charge cord into the matching DC input port.
Now plug the charger into an AC outlet.
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 speaker that light in succession as internal battery charging progresses.
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.
The battery recharge cycle finishes when all battery status gauge lights go out.
The next picture shows the round charging port on the Xtreme after we removed the charge cord.
Be sure to completely close the power port door. Why? Because unless you do, water could enter the ports. Then this may damage the components inside. So, take care to completely zip the port door closed. Doing so gives full water resistance.
See how this port door looks when fully closed and sealed.
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 has a full charge.
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.
