JBL Flip 4 Charging Instructions for Longest Play

Follow these JBL Flip 4 charging instructions for longest play using the hidden USB DC input port.  It’s important when charging this Bluetooth speaker, to allow the cycle to finish.  This assures that you get full recharging and that the speaker plays for the longest time before needing another charge session.

JBL Flip 4 Charging Instructions: Introduction

First, select an adequate USB adapter.  Why ?  Because the Flip 4 does not come with this as a standard accessory, and for longest play, you want to the strongest charger. Plus, the Flip 4 needs a high power USB power source for charging fully in a fastest time possible.

Next, connect the orange micro USB cable between the Flip 4 and that charger.  Next, plug the adapter into a working wall outlet.

Finally after a few to four hours, full charging of your JBL speaker completes. Then you can play it again for up to twelve hours before the battery goes dead again.

At least one of the battery status lamps lights up on the Flip 4 when you apply enough USB power.  There are five lamps that light in succession as the speaker battery charging progresses, as shown in the next picture.

6. Let the Flip 4 Charging Run Until All Battery Power Lights Go OFF

Battery charging is done when all but the last of the battery status lights light solid.  The last one continues to blink for several minutes.





This next picture shows the speaker just before completing a full charge cycle. Note that all the lamps in the battery status gauge are glowing.  However, the last one continues to blink.

8. Snap Closed the Port Door

Note that unless this flap is snapped securely and completely in place, water could enter the port area, possibly damaging the Flip 4 electronics inside.  So, be sure to press the port door closed with enough force to properly seat it, for full water resistance.

9. Done!

We have now fully charged our JBL Flip 4 wireless Bluetooth speaker.  Note that the battery charge status gauge just after turning on the Flip 4 after a full recharge.  All lamps are aglow, meaning that the speaker is current fully charged.

Repeat this process every ten to twelve hours of music play through the Flip 4, to keep its battery in top condition. We charge ours when the battery status gauge lights show only one light glowing.
