Recharge this speaker through the USB-C charging port on its back. To summarize how to charge the JBL Charge 5: First, choose a USB power adapter that’s big enough.
Next, connect the Black USB-C cable included with the speaker between the Charge 5 and the power adapter you’re using. Then plug the adapter into a working wall outlet. Finally after four to five hours, your speaker will fully recharge. Then, you can play it again for up to twenty hours roughly, before you must recharge it again.
How to Charge JBL Charge 5: Step by Step
1. Choose Right Size Charger
The power supply you use here should be able deliver 15 watts (5 volts at 3 amps). This gives the quickest charging times. Plus, to avoid having to get a different cord, pick a charger with a female USB-A port. Then you can use the cord that comes with the Charge 5.
For this demo though, we use the adapter that came with this speaker. And though it doesn’t output quite the max current, the speaker still charges in about the same time.
2. Plug in the USB-C Cord to Continue with How to Charge JBL Charge 5
Insert the small end of the black USB-C charging cable into the matching port in the speaker, as shown above.
3. Plug the Other End of the Cord into the Power Adapter
Next, connect the A end of the USB charge cable to your USB power supply of choice.
4. Plug that Power Adapter into a Working Outlet
Then plug the charger into a working AC outlet.
At least part of the battery status gauge bar lights up on the speaker when you apply enough USB power. As charging progresses, as shown in the next picture, more of this bar lights up, starting with the bottom.
5. Allow the Speaker to Charge Until the Battery Meter Bar Goes Out
Recharging is almost complete when all but the top of the battery gauge glows solid. That part keeps flashing though, for a few minutes more while the system tops off the charging.
After that, the cycle is complete when this gauge goes out.
6. Unplug the USB-C Charge Cable
7. Done !
Finally we have now fully charged our speaker. To further confirm this, check out the battery meter just after turning on the speaker afterwards. The entire meter bar should now glow. This means that the speaker now has a full charge.
Repeat this charging every twenty hours of music play, to keep its battery in top working condition. In fact, we charge ours when the battery gauge shows only one light glowing.
