JBL Wonderboom Wattage

The JBL Wonderboom is a small power, hand-held format unit with enough wattage to fill a smaller size room with full sounding tunes.

But what does the wattage a BT speaker has, say about how good it is? Firstly, the watt is a measure of how much power the speaker uses and pumps out. Plus, this metric is a telling comparison measure. Why? Because generally, speakers with more watts of audio tend to play louder than those with less.

While they do cost more, have bigger, heavier batteries and chargers, along with larger drivers and magnets, they nonetheless offer some big plusses. They have more dynamic range, a deeper bass response, and the models that play in stereo like the JBL Wonderboom, offer typically a bigger soundstage and better stereo imaging to listeners.

Thus in general, the more powerful the speaker, the better it sounds, even at lower volume. You get improved clarity due to higher accuracy reproduction of the bass, midrange, and treble parts of the program. Plus, more reserve power likely means less clipping too, even at loudest volumes. So, the speaker’s maximum wattage output gives a good idea about speaker quality and performance. And as such, this value is of great interest to audiophiles and novice listeners alike.

In this case, the UE JBL Wonderboom, as a mini size portable BT speaker, is a decently loud model. Its more than ten watts can fill a small to medium size party area with clear and full music. See below for details on its power output.

Notes on JBL Wonderboom Wattage

1. This JBL Wonderboom unit may not input enough enough power from a low power USB AC adapter (under 10 watts capacity) to keep the battery from discharging when playing at max volume, depending on what you’re listening to. So it could happen that even with this unit fed from external power, you could still see the music drop out abruptly. Thus on the (rare) times that this occurs, just stop playing the speaker for an hour or two, to let it build up some reserve battery power while charging. Then, fire it up again for continued party enjoyment.
