Covers why you might notice the JBL Speaker Blinking White Light and Making Noise. This could be due to a wet or defective charging port. So be sure the port is dry and free of debris before following this procedure to charge the Flip.
Recharge the speaker through the charging port. To summarize: First, pick the right size USB power adapter. Note that this speaker does not ship with one.
Next, connect a thicker USB-C cable between the speaker and the power supply you’re using. Next, plug the adapter into a working mains outlet. Finally after two and a half to three hours, your Flip will completely recharge. It should never beep during recharging. Then, you’ll have music again for up to twelve hours (about), before you must charge it anew.

JBL Speaker Blinking White Light and Making Noise: Step by Step: Safest Way to Avoid This Noise

1. Choose a Large Enough Charger
The adapter you use should be able deliver 15 watts (5 volts at 3 amps) for shortest recharging times. Also you may want to use the cord that comes with the Flip. In that case, pick a charger with a female USB-A output port. Again, be sure both the port on the Flip as well as the plug on the cord are completely dry and clean.
Here though, we use the adapter that came with our Charge 3 JBL Speaker. True that it doesn’t output quite the max current for JBL Speaker. Yet the charge time is still about the same.
2. Plug in the USB-C Cord to Continue with Fixing the JBL Speaker Blinking White Light and Making Noise
Insert the small end of your USB-C charging cable into the matching port in the speaker front.
3. Plug the Other End of the Cord into the Power Adapter
Next, connect the other end of the USB charge cable to your power supply of choice.
4. Plug that Wall Adapter into a Working Outlet
Then plug the charger into a working AC outlet.

At least a small part of the battery bar gauge should light when you apply USB power. As charging progresses, more of the bar glows.
5. Let the Flip Charge Until All Battery Indicator Lamps Go Out
Recharging is almost complete when all but the last of the battery gauge lights glow solid. The last one continues flashing though, for a few minutes more while the system tops off the charging.
After that, the battery recharge cycle finishes when the gauge goes out completely.
6. Unplug the Charging Cable
7. Charging Without JBL Speaker Blinking White Light and Making Noise is Complete !
We have now fully charged our speaker. To further check this, look at the battery indicator just after turning on the speaker afterwards. The entire battery gauge bar should glow, as shown next. This means that the speaker has indeed fully charged.

The battery gauge bar is to the right on the front panel, as shown in the last picture.
Repeat this recharging every twelve hours of music play, to keep its battery in top condition. We charge ours when the battery indicator shows only one light glowing.
