Telling That Logitech Wonderboom is Charging

Explains the details of Telling That Logitech Wonderboom is Charging. This Bluetooth speaker with built in hanger loop has a two-color LED lamp on its top, in the Power button, as shown in the pictures next. This light not only gives speaker power OFF ON and pairing status. But it also tells battery level (whether it’s near dead or not) as well as charging status. To see if the Wonderboom is charging, check this light. We show how to read it next.

Telling That Logitech Wonderboom is Charging: Step by Step

1. Connect your Speaker to USB Power

Of course, you know that this speaker is NOT charging with no charging cable plugged in.

2. Check the Status / Power LED on Speaker Top

Whether this unit is OFF or ON, you can tell if the Logitech Wonderboom is charging if it is indeed connected to a charger, the Power lamp is lit white, and slowly brightening and dimming in a pulsating pattern.

When not charging, this light glows steady red when the battery has about run entirely out of power. It glows solid white otherwise when the speaker is powered ON. The lamp is OFF when the speaker is OFF and not connected to a charger supply.

Should the Logitech Wonderboom power lamp glow steady red with the power then the speaker is not charging. So you might check that your USB cable, adapter charger, and power source are working. Try a new USB adapter or another charge cord. This light should blink white to know for sure that the unit is charging.

Now, this speaker does not warm very much as it charges. But you can feel charger adapter to verify charging in progress. If the charger warms, then it is delivering substantial current to the unit. Moderate charger heating is a decent way to tell if the Logitech Wonderboom is charging.

As speaker charging wraps up, the status LED keeps flashing white. But this speaker gives no more of a granular reading of just how far along its recharging is. The power lamp just shows that charging is indeed going on. See the white glowing lamp in the last picture, pointed at by the green arrow.

3. When the Power LED Goes Off or Turns Solid White, Then Logitech Wonderboom Charging is Done

The battery charge cycle is finished when the power LED changes from pulsating white to either OFF or solid, as shown in the next two pictures.

Even with the charger cord still plugged in, and when the speaker is powered down, this lamp stops glowing entirely when the internal battery is full, as shown next. The Logitech Wonderboom no longer recharges when the battery reaches full charge condition.

4. Finally, Unplug the Speaker and Power it On

If the power LED glows solid white as pictured above, this could mean that it did indeed charge when linked to external power, particularly if the unit was dead or near dead before you plugged it in. But with the USB cable disconnected, we cannot know just by reading the power LED, just how much this speaker actually recharged, only that it did charge some. It likely did charge to full though, as long as we waited until the light stopped blinking before unplugging the charger.

Happy listening to your Wonderboom Logitech speaker!
