How to Know If JBL Charge 5 Speaker Is Fully Charged

To summarize how to know if JBL Charge 5 speaker is fully charged…

1. First, choose a USB power adapter that’s big enough. Details below.
2. Next, connect the black USB-C cable that comes with the speaker between the 5 and charger. Too thin a cable will not get you to fully charged state as fast as possible.
3. Then plug the adapter into a working wall outlet. A warming charger precedes a fully charged speaker. So if the adapter does not warm during recharging, then the JBL Charge 5 speaker will likely not fully charge.
4. Finally after four to five hours, the 5 should fully charge if all the above conditions hold true.
5. Furthermore, the charge gauge should fully glow when operating the speaker.
6. Then, you can play it again for up to twenty hours roughly, before you must recharge it again. If it does not play for roughly this time, then perhaps you did not fully charge it. Shortened play is indeed a sign that the speaker is not fully charged.

How to Know If JBL Charge 5 Speaker Is Fully Charged: Step by Step

A charging cable inserted.

1. Choose Right Size Charger

The power supply you use here should be able deliver 15 watts (5 volts at 3 amps). This gives the quickest charging times. Indeed the Charge 5 may not charge fully in the shortest possible times with a charger that is too small. Plus, to avoid having to get a different cord, pick a charger with a female USB-A port. Then you can use the cord that comes with the speaker.

For this demo though, we use the adapter that comes with the speaker. And though it doesn’t output quite the max current, the 5 still charges in about the same time.

2. Plug in the USB-C Cord to Continue with How to Know If JBL Charge 5 Speaker Is Fully Charged

Insert the small end of the black USB-C charging cable into the matching port in the 5. Of course you cannot know if the speaker is fully charged without connecting the cable first.

3. Plug the Other End of the Cord into the Charger

Next, connect the A end of the USB charge cable to your USB power supply of choice.

4. Plug that Charger into a Working Outlet

Then plug the charger into a working AC outlet.

At least part of the battery status gauge bar lights up on the speaker when you apply enough USB power. As charging progresses, more of this bar lights up, starting with the bottom.

5. Allow the Speaker to Charge Until the Battery Meter Bar Goes Out

Recharging is almost complete when all but the top of the battery gauge glows solid. That part keeps flashing though, for a few minutes more while the system tops off the charging.

After that, the cycle is complete when this gauge goes out.

6. Unplug the USB-C Charge Cable

7. Done with How to Know If JBL Charge 5 Speaker Is Fully Charged !

Finally we have now fully charged the speaker. To further confirm this, check out the battery meter just after turning on the speaker afterwards. The entire meter bar should now glow. This means that the speaker now has a full charge.

Repeat this charging every twenty hours of music play, to keep its battery in top working condition. In fact, we charge ours when the battery gauge shows only one light glowing.
