You charge the Wonderboom Speaker via the covered micro USB charge port. And to get the quickest Wonderboom Speaker charge time and fullest charge when the speaker runs low on power, be sure to use a medium to high current USB charger. Also, exercise the battery, and do not leave the speaker on the charger once it has fully recharged.
Wonderboom Speaker Charge Time: How Long to Fully Recharge
According to the specs for this speaker the time it takes to charge the Wonderboom Speaker BT speaker is just under three hours (2.8 hours to be exact).
How Long it Plays Per Full Charge
On a complete charge, the Wonderboom Speaker speaker can play for up to ten (10) hours per charge. But when you play it loudly, especially with extra bass, you will see somewhat shorter lasting power. We’ve seen this Bluetooth speaker run dead in around eight hours when played at louder volumes. So to get the longest charge time from it, power saving is key. Just play it only as loudly as you need to, to hear it well throughout your listening space.
The Charge Time Gets Smaller as the Wonderboom Speaker Grows Older
If you own this speaker over a few to several years, you may notice that the time it plays from a single charge shrinks as the speaker gets older. This is normal for devices like this one, that rely on lithium ion batteries.
But by exercising the battery, you can slow this charge fall off.
To exercise the Wonderboom Speaker, run the battery dead and charge it again every three to six months when not in use.
Also, we recommend that you not leave the speaker plugged into a charger once it has reached full charge. Right after the charging lamp completely goes out, disconnect the speaker as soon as you can, to avoid overcharging it and damaging the battery.
