A decent Ultimate Ears Wonderboom speaker charger is a USB AC charger that supplies at least 2.1 amps at 5 volts (12 watts or more). Note that currently, Ultimate Ears does not provide a compatible USB charger with this speaker. So, you’ll need to get one elsewhere. These typically cost between ten and forty US dollars.
Ultimate Ears Wonderboom Speaker Charger: Which to Buy
We’ve successfully charged our Ultimate Ears Wonderboom Bluetooth speaker with the chargers, listed below. Each works quite well as replacement for any charger that worked before needing replaced. Note that all these chargers sport at least one USB A type female connector. You’ll need an AC adapter like these to connect your speaker if you wish to use the yellow USB charging cable that comes with the speaker. Or, use a longer cord if you so desire, but make sure it supports full power USB charging. If not, your speaker will charge more slowly, and may not fully charge at all. So pick a thick USB cord.
