How to Charge Logitech Wonderboom Speaker

Covers how to charge Logitech Wonderboom Bluetooth portable speakers easily through the hidden micro USB charge port on the back of the speaker, near the bottom.

In a nut shell: First, select a hefty enough USB power adapter. Why? Because Logitech does not include this with the Wonderboom.  But they do sell one for roughly $20 US.





Next, connect a micro USB charge cord between the Wonderboom and that adapter. Then, plug that power supply into a working AC mains outlet.

Finally after a few hours, the speaker fully recharges.  Then, you can play it again for maybe ten hours before it runs dead again.

How to Charge Logitech Wonderboom Speaker

1. Choose Strong Enough USB Charger

In this demo, we’re using the iClever 24 watt AC  USB charger, as shown next.  The Wonderboom needs 5 volts at 0.6 amps to charge fully in a moderate amount of time.  So this iClever USB wall adapter is indeed strong enough to recharge the WB.

2. Open the USB Port Cover

Use a dime or penny to open the waterproof seal port cover on the WB. This uncovers the micro USB charging port inside, as shown next.

3. Power Off the Wonderboom

Note that the Wonderboom  still charges when running.  But depending on your charger, it may finish in a shorter time when turned OFF.





4. Plug in the Micro USB Cord

Then, plug the small end of your micro USB charge cable into the matching micro USB port in the rear of this speaker, as shown next.

5. Plug the Other End of the USB Cord into the AC Adapter

Next, connect the A end of the USB charge cable to the power adapter.  In this demo, as we said earlier, we use an iClever 24 Watt 2.1 amp per port USB power adapter along with a generic micro USB cable.

6. Plug the AC USB Power Adapter into a Wall Outlet

Now that we connected the Logitech speaker and charger, we plug the power supply into a working AC outlet, as shown next. In this demo, we plugged ours into a wall receptacle in the kitchen.

The status light in the power button lights a fading and brightening white pattern on the speaker with enough USB power. While no battery status gauge shows charge percentage, the pulsating white lamp means that charging is in progress.

Then when the speaker is OFF, this lamp goes out when charging finishes  If the speaker is ON, this lamp starts glowing a solid white once more.

7. Let the Speaker Charge Until the the Power Lamp Stops Blinking

Battery charging is complete when the gradually brightening and fading power lamp stops pulsating.  Detail: when the speaker is OFF, this lamp goes out when charging finishes  But if the speaker is ON, the light starts glowing a solid white once more.





8. Unplug the USB Cord

9. Close the USB Door

Note that unless you snap this door tightly into place, water might get inside the speaker. This could affect its electronics in a bad way. So, be sure to press door closed with ample pressure to fully seat it, to ensure full water resistance.
