Explains how to charge the JBL Xtreme 1 through its DC input port and the included 19 volt adapter.

How to Charge JBL Xtreme 1: Summary

In short, first, we suggest that you charge the Xtreme 1 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 1. So, we won’t buck any systems here, and will indeed use that charger. But in a bind, you could fully charge the Xtreme 1 with other vendors’ wall chargers. But we won’t discuss those options in this post.

It’s time to charge this speaker when the battery status gauge shows a single flashing red light.

When you see the blinking red lamp, plug the black barrel DC output charge cord jack into the Xtreme 1. Then, plug the charger into a working wall outlet.

Finally after a few hours, the Xtreme 1 fully charges. Then, play it again for roughly fifteen hours before you have to charge it again.

At least one of the battery status lamps lights on the Xtreme 1 when everything is working correctly. Five lamps on this speaker light in succession as battery charge progresses.

5. Allow the Speaker to Charge Until All Battery Power Lights Go Out

Then battery charging is almost complete when only the last of the charge status lights is either OFF or blinking. The last then blinks for several minutes more to finish off the charge.

So the next picture shows the round charging port on the speaker after we took out the charge cord.

7. Fully Zip Up the Weather Resistant Port Door

Then unless you fully zip up this power port opening flap, water might enter the connector area. It could then damage speaker components inside. So, take great care to fully close this port door for full water resistance.

8. Done with How to Charge JBL Xtreme 1 !

At last we have now fully charged this Bluetooth speaker. Note that the battery charge status gauge just after turning on the unit after a full recharge. All lamps are aglow.

Finally, repeat this process every fifteen hours of play to keep the battery in good condition. We charge ours when the gauge lights show just one lamp glowing.
