How to Tell if JBL Charge 3 is Charging

How to tell if JBL Charge 3 is charging?  Well, this Bluetooth speaker with power bank has a lone row of small LED lamps across its pedestal, as shown in the pictures coming up.  These lights display battery charge level status.  To tell if this speaker is charging, look at these to see Charge 3 charging in action and how to know that the speaker is indeed taking on energy.

How to Tell if JBL Charge 3 is Charging

Connect your Charge Three to AC Power

Obviously, you can be sure that this speaker is NOT charging when no cord is connected to it.

Check the Battery Status Lamps

There are five lamps that light in succession as the Charge 3 battery charging moves forward, as we show in the next picture.  You can tell if the JBL Charge 3 is charging if you see one of these lamps flashing white.  When the battery inside is  dead all the way, the light on the far left blinks white while charging.  Then as the battery fills, that lamp switches to a steady white glow.  At that time, the next lamp to the right starts blinking white.

Also, the speaker heats up a bit during charging as does its USB charger.  This warmth is an excellent way how to tell if the JBL Charge 3 is charging.

When All Lamps Light Solid, Charging is Close to Finished

As speaker charging persists, more and more of the lamps light up solid, and the flashing moves further to the right, until it reaches the last of these five battery level indicator lamps.  This next-in-line lighting is another indication that the Charge 3 is in fact, charging.

This next picture shows the speaker just before wrapping up a charging cycle. Note that all the lamps in the battery status meter glow.  But the last one goes on blinking for several minutes.  When one light blinks while a working charger is connected, this is another way that the speaker tells us that the Charge 3 is recharging.

The battery recharge cycle finishes when all charge status gauge lamps go dark, as shown next. Thus, the battery is no longer recharging when all lamps are OFF. Even with the charger cord still plugged in, no lamp glows when battery is full.  The speaker no longer charges when the battery reaches this state.

Finally, Unplug the Speaker and Turn it On

If the battery gauge reads full, this tells you that the speaker did indeed charge when connected to AC power.

Take care.
