JBL Xtreme 2 Charging Instructions

Gives JBL Xtreme 2 charging instructions through this speaker’s DC input port and the included 19 volt AC adapter. Follow these steps, and you’ll likely never experience the speaker not recharging. If all components are working, charging almost always works well.

JBL Xtreme 2 Charging Instructions: Initial Remarks

In short, first, we suggest 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 can charge the speaker with other vendors’ adapters. But we won’t discuss those options here.

Now, it’s time for charging 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 complete charging of the speaker before you can play it again. The speaker will indeed play while recharging, 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 need to charge it again.

2. Open the Charging Port Cover

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

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. Let the Recharging Run Until All Battery Power Lights Go Off

Battery charging is almost complete when only the last of the gauge lights blinks. It then blinks for several minutes more to top off the charge.

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 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 !

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