In short, first select a powerful enough USB power adapter. Why? Because Ultimate Ears does not include this with the Ultimate Ears 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 WB and that adapter. Then, plug that power supply into a working AC receptacle.

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

The speaker 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 unit with lots of energy to spare.
