You can recharge the JBL Charge 4 portable speakers through their hidden USB charging connections. To summarize how to charge the JBL Charge 4 : First, choose a right sized USB power adapter.
Next, connect the Black USB-C cable included with the speaker between the Charge 4 and the power adapter you’re using. Next, plug the adapter into a working wall outlet. Finally after four to five hours, your speaker will fully charge. Then, you’ll be able to play it again for up to twenty hours roughly, before you must recharge it again.
How to Charge JBL Charge 4 Wireless Bluetooth Speaker
1. Choose Right Size Charger
The power supply you use to charge this speaker should be able deliver 15 watts (5 volts at 3 amps) to get the quickest charging times. Plus, to avoid having to get a different cord, pick a charger with a female USB-A output port so that the included cable with this speaker will fit it.
For this demo however, we use the adapter that came with our Charge 3 JBL, and though it doesn’t output quite the max current, the speaker still charges in about the same time.
2. Open the Port Cover on the Back of the JBL Charge 4
Pry open the waterproof seal port cover on the speaker rear. This reveals the USB-C charging port inside, as shown next. It’s the port on the left.
3. Plug in the USB-C Cord to Continue with How to Charge JBL Charge 4
Insert the small end of the black USB-C charging cable into the matching port in the speaker, as shown next.
4. Plug the Other End of the Cord into the Power Adapter
Next, connect the A end of the USB charge cable to your power supply of choice.
5. Plug that Wall Adapter into a Working Outlet
Now that the speaker and the AC adapter are connected, we plug the charger into a working AC outlet, as shown next. In our case, we’re charging from a surge protecting power strip, as shown next.
At least one of the battery status lamps lights up on the speaker when you apply enough USB power. There are five lamps on this speaker that light one after the other, as charging progresses, as shown in the next picture.
6. Allow the Speaker to Charge Until All Battery Indicator Lamps Go Out
Recharging is almost done 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 all battery status gauge lights go out.
7. Unplug the USB-C Charge Cable
8. Fully Close the Waterproof Port Door
Note that unless this flap is closed completely, water may enter the port area, and damage perhaps, the electronics inside. So, be attentive, and press the port door closed, with enough pressure to fully seat it, to get full water resistance. See how this port door looks when closed the right way in the next picture.
9. Done with How to Charge the JBL Charge 4 !
We have now fully charged our speaker. To further confirm this, check out the battery indicator just after turning on the speaker afterwards. All lamps glow, meaning that the speaker is fully charged.
Repeat this recharging every twenty hours of music play, to keep its battery in top working order. We charge ours when the battery indicator shows only one light glowing.
