How to Replace the Charge Port on a JBL Charge 3 Wireless Speaker

If you find that your JBL Charge 3 will only charge when you hold the cord in a specific spot and you have tried other cords, your charge port is likely the issue. We sell New Replacement Charge Ports for this speaker and this guide shows you how to install them. This repair requires some specialty tools and confidence with a fine tip soldering iron. Because of this, it might end up being cheaper for you to send the speaker into us for repair unless you plan to continue to use the tools or already own them.

Repair Difficulty: Difficult

Time to complete: 90 minutes

The tools and parts that you will need for this repair: 

  1. A New Replacement Charge Port
  2. A pry tool (The dull edge of a butterknife will work)
  3. A fine tip soldering iron (around 15 watts is good for small electronics and would be cheaper than purchasing a temperature variable unit).
  4. Solder Flux (To ensure clean solder joints)
  5. Heat Gun (A hairdryer normally would work but in this case, you need a heat gun with a more fine tip and temperature control)
  6. A standard Phillips screwdriver
  7. A Small Flat Edge Screwdriver
  8. Some Precision Tweezers

***Optional if you want to give the best contact for the new charger port.

  1. Solder wick (to remove all of the old solder)
  2. Rubbing alcohol (to clean the contact pads on the circuit board after removing the solder)

 

1. Remove the fabric covering

Insert your pry tool into the seam of the fabric covering on the bottom of the speaker and pry up the side that is facing to the back of the speaker. 

Prying the fabric cover up and away from the speaker  

 

Unscrew the two screws that you just uncovered by prying up the fabric cover.

Removing the two visible screws just inside of the fabric 

 

Remove the fabric covering from the speaker by gently pulling it up and away from the plastic body of the speaker. It is only held on with some snap connectors so there is no need to worry if you hear some small pops as you remove it. 

Pulling the cloth away from the speaker.  

 

2. Remove the rubber base

The bottom of the speaker is a flat rubber stand so that the speaker does not roll around. There are six screws holding that rubber stand in place, remove all four.

Now, remove the screws from the battery housing that you just uncovered. There are seven screws holding it in place.

3. Remove the charge port assembly

Removing the battery cover will provide you with access to the two screws that are left holding the charger port assembly in place, remove those screws.

Now unplug the two plugs that hold the charger port's circuit board into place. They should pull straight out from the circuit board. After you have unplugged them, you can remove the whole assembly from the speaker.

4. Removing the old charge port

Put the circuit board in a vice if you have one or place it on a surface that will not melt or burn when you heat up the charge port. Then, grab the charge port with your tweezers and begin moving the hot air around it. Make sure to keep the hot air away from other components on the circuit board as much as possible. 

Heating up the old charge port with a heat gun  

 

After 10-15 seconds of heat, you should be able to pull the charge port out of the circuit board. 

 The charge port should come off after a few seconds of heating up all of the solder

 

Check the small. contacts on the circuit board to ensure that they are not bridged with solder. 

The contacts for the back of the charge port 

 

If the contacts are bridged, you can either clean them up with a fine tip soldering iron, or you can use solder wick and flux to remove all of the old solder so that the new charge port can be easily placed on the board.

5. Installing the new charge port

Push the metal anchor studs of the new charge port through the holes on the circuit board so that it is lined up properly. If the anchor studs won't fit through the holes due to solder, you may need to use some solder wick to remove the old solder or heat it up with your soldering iron. 

The anchor points on the charge port should slide into the holes in the PCB 

 

Apply solder flux to the studs of the charge port.

Applying flux to the anchor points and circuit board 

 

Apply fresh solder to all six of the anchor points on the bottom of the circuit board to secure the new port into place. 

Applying solder to the anchor points 

 

Solder all of the tiny contacts on the back of the charge port down onto the circuit board. Make sure that the contacts or solder are not bridged to other contacts and ensure that each contact wire is firmly attached to the circuit board using your Small Flat Edge Screwdriver.

6. Reinserting the charger port assembly

Slide the charge port circuit board into its housing.
