Here’s our answer to the question: How Do I Know When My UE Wonderboom 1 Is Fully Charged? Charging is easy through the sealed micro USB DC in port on the rear bottom of the speaker. First, pick a high current USB AC adapter. Why? Because you do not get this with the 1. But the company does offer one that works well for less than twenty US dollars.

Next, connect a micro USB charge cord between the UE Wonderboom 1 and that adapter. Then, plug that power supply into a working AC mains outlet.

Finally after roughly three hours, the speaker fully recharges. Then, you can play it again for around thirteen hours before it runs dead again.

How Do I Know When My UE Wonderboom 1 Is Fully Charged: Step by Step

1. Choose Strong Enough USB Charger

In this demo, we’re using the iClever 24 watt AC USB charger, as shown next. The 1 needs 5 volts at about 1.0 amp to charge fully in the shortest time. So this iClever USB wall adapter is indeed strong enough for the job.
