You can charge JBL Flip 4 wireless speakers conveniently via their hidden USB charge ports. To summarize: First, select an adequate USB power adapter. Why this? Because the Flip 4 does not come with this as a standard accessory.
Plus, the Flip 4 needs a high power USB power source to charge fully in a reasonable amount of time.
Next, connect the orange micro USB cable between the Flip 4 and that adapter. Then, plug the adapter into a working wall outlet.
Finally after a few to four hours, your Flip 4 fully charges. Then you’ll be able to play it again for up to twelve hours before you must charge it again.
