How to Charge UE Wonderboom Speaker

Covers how to charge UE Wonderboom wireless Bluetooth speakers easily. Use the hidden micro USB charge port on the back of the speaker, near the bottom. So here, we run through the charging instructions for this “big sounding” portable speaker.

In short, first select a powerful enough USB power adapter. Why? Because Logitech does not include this with the Wonderboom as a standard accessory. But you can buy one from them for roughly $20 US if you wish.

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

Finally after a few hours, your Ultimate Ears Wonderboom speaker fully recharges.  Then you can play it again for perhaps ten hours before it needs another charge.

How to Charge UE Wonderboom Speaker Instructions

1. Choose Right Size USB Adapter

First of all, we charge the speaker with the iClever 24 watt dual port USB charger adapter, as shown next.  The UE Wonderboom needs 5 volts at approximately 0.6 amps to charge fully in a reasonable amount of time.  So this iClever USB wall adapter is indeed strong enough to recharge the UE with lots of energy to spare.

2. Open the Port Cover on the UE Wonderboom

Second, use a penny or a dime to pry open the waterproof seal port cover on the WB. This reveals the micro USB charging port inside, as shown next.

3. Power Off your Speaker

Next, note that the Wonderboom  still charges when powered up.  But depending on your charger, it may recharge slightly faster when turned OFF.

4. Plug in the Micro USB Cord to the Wonderboom

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

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

Then, connect the A end of the USB charge cable to the power adapter. Furthermore, in this demo, we use an iClever 24 Watt 2.1 amp per port USB power adapter.  We also supply our own generic micro USB cable.

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

Now that we connected the Wonderboom and charger, we plug the iClever into a working AC outlet, as shown next. In this demo, we plugged ours into a wall outlet in our kitchen.

The status lamp in the power button lights a fading and brightening white pattern when you supply enough USB power. While no battery status gauge shows percentage of charge, the pulsating white lamp means that charging is happening.  Then when the speaker is OFF, it goes out when charging completes.  If the speaker is ON, this lamp starts glowing a solid white.

7. Let the UE Wonderboom Charge Until the the Power Lamp Stops Pulsating

Battery charging is complete when the gradually brightening and fading power lamp stops pulsating.

8. Unplug the USB Charge Cable

9. Fully Close the USB Port Door

Note that unless you snap this Wonderboom port door tightly into place, water could enter this area. Then this might damage the electronics inside the speaker. So, be sure to press door closed with firm force to seat it, for full water resistance.

10. Done!

Finally, we have now fully charged our Ultimate Ears Wonderboom wireless Bluetooth speaker.

At last, for best battery performance, repeat this recharging every ten hours of play time. This keeps the battery in top working order for months to come. Further, don’t let the battery stay dead for very long. Why?  Because if it remains dead for too long, it can stay that way even when you try to recharge it.
