You can recharge the JBL Charge 5 speaker through the USB-C port at the rear of the speaker. To summarize charging JBL Charge 5 speaker: First, choose a right size USB power adapter, which we detail below.
Next, connect the Black USB-C cable included with the 5 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.
Charging JBL Charge 5 Speaker: Step by Step
1. Choose Right Size Charger
The charger you use should be able deliver 15 watts (5 volts at 3 amps) for fastest recharging. Plus, pick one with a female USB-A output port so that the included cable with the 5 will fit it.
For this demo though, we use the adapter that came with our Charge 5. But though it doesn’t output quite the max current, the unit still charges in about the same time.
2. Plug in the USB-C Cord to Continue with Charging JBL Charge 5 Speaker
Insert the small end of the black USB-C cable into the matching port in the 5.
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 to Continue with Charging JBL Charge 5 Speaker
Now that the charger is present, we plug it into a working AC outlet.
At least part of the battery status gauge bar lights up on the 5 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 Charging to Continue Until the Battery Meter Bar Goes Dark
Recharging is almost complete when all but the top part of the battery gauge glows solid. The topmost part keeps flashing though, for a few minutes more while the system tops off the charging.
After that, the battery charge cycle finishes when this gauge goes out.
6. Unplug the USB-C Charge Cable
7. Done with Charging JBL Charge 5 Speaker !
We have now fully charged our speaker. To further confirm this, check out the battery meter just after turning on the 5 afterwards. The entire meter bar should now glow, meaning that the 5 is now at 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.
