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.
How to Charge JBL Xtreme 2, Step by Step
1. For Best Results, Use the Included Power Adapter
As mentioned above, we use the JBL wall charger that comes with this speaker, as shown next.
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.
3. Plug the DC Power Cord into the Speaker to Continue with How to Charge JBL Xtreme 2
Then, plug the barrel connector end of the wall adapter’s cord into the matching DC input port on the speaker, as shown next.
4. Plug the AC Power Adapter into a Working Power Outlet
Now that the Xtreme 2 and its 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 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.
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 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.
How to Charge JBL Xtreme 2 Frequently Asked Questions (FAQ)
Why Does my JBL Xtreme 2 Keep Shutting Off ?
An aging internal battery may cause this, as the battery can no longer deliver the minimum current the Xtreme needs to work properly. Installing a new battery often solves this issue. We suggest though, that you consult a qualified electronics technician to install a new battery.
What’s the JBL Xtreme 2 Charge Time ?
The Xtreme speaker fully charges between three and four hours, depending on the state of the battery when recharging starts. This assumes that you use the charger that comes with the speaker. Other wall chargers may take longer to fully recharge the Xtreme speaker.
How to Shut Off JBL Xtreme 2 ?
When the speaker is ON, the power button glows or flashes either blue or white depending on the mode it’s currently in. Press this button to shut it off. All lights should go out within a couple seconds. The speaker should also play that JBL trademark falling guitar cord sound.
How to Turn On JBL Xtreme 2 ?
No lights glow, and no sound comes from the speaker when it’s OFF. Turn it on by pressing the Power button. See the Power button location shown in the next picture.
What Does the JBL Xtreme 2 Flashing Red Light Mean?
When you see the red light blinking on the JBL Xtreme 2’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 charged again. See the red light we’re talking about in the last picture above, pointed out by the green arrow. Note though that this lamp never flashes red when you connect a working charger. As you charge the speaker from an almost dead state, one of the battery gauge lamps blinks white.
