Lists ways of Telling That JBL Charge 3 is Charging. Now this BT speaker with power bank has a lone row of small LED lamps across its front. These display battery charge status. To tell if charging is happening, just look at these. Details follow.
Telling That JBL Charge 3 is Charging: Step by Step
Connect your JBL Charge 3 to AC Power
Obviously, you can be sure that this speaker is NOT charging when there is no cord connection.
Check the Battery Status Lamps
There are five lamps that light in succession as charging advances. 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 of the lamps light up solid. And the flashing moves further to the right, until it reaches the last lamp. This next-in-line lighting is another indication that the JBL 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 white, a working charger is present. This is another way that the speaker tells us that it is charging.
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 JBL Charge 3 and Turn it On
If the battery gauge reads full, this tells you that the speaker did indeed charge when connected to AC power.
