Here’s how to charge JBL Xtreme 2 through its DC input power port using the included 19 volt charger. Follow these tips, and you’ll likely never see that the speaker won’t charge. And if all components are working properly, it will always charge if you follow this routine.
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. But it might take slightly longer to charge when you listen 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.
How to Charge JBL Xtreme 2, Step by Step
1. For Best Results, Use the Included Power Adapter
Firstly, as mentioned above, we use the JBL wall charger that comes with this speaker, as shown next.
2. Open the Speaker Charging Port Cover
Then stick a coin or straight screwdriver into the slot at the top of the port door. Pry it open next. This then exposes the USB power out and charging port inside.
3. Plug the DC Power Cord into the Speaker to Continue with How to Charge JBL Xtreme 2
Then plug the barrel connector end into the matching DC input port on the speaker.
4. Plug the AC Power Adapter into a Working Power Outlet
Then connect the charger to a functioning AC outlet.
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 complete 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.
The battery recharge cycle finishes when all battery status gauge lights go out, as shown next.
6. Unplug the DC Cable from the Speaker to Continue with How to Charge JBL Xtreme 2
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 has a fully 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.
