How to Fix When TOZO Earbuds Not Charging?
Tip: Follow our steps in a consecutive order!
1. Alter the Charging Method
An issue with the charging source could impact the earbuds’ charging the most.
So, this step will review several alternative methods to provide the TOZO earbuds with power.
This will help you keep the TOZO earbuds working while identifying the fault with the previous charging method.
Here are a few different charging methods you can attempt on your earbuds:
- Charge the TOZO earbuds case through an alternative power outlet.
- Charge the TOZO earbuds through the USB port on your PC/laptop.
- Charge the TOZO earbuds wirelessly as long as they are compatible.
How to Charge TOZO Earbuds Wirelessly?
The TOZO earbuds can charge wirelessly if your model supports this function.
The models that support wireless charging are the TOZO T6 True Wireless and the TOZO T10 earbuds, so check the box of the earbuds to recover the model.
Here’s how to do wireless charging on the TOZO earbuds:
- Ensure the earbuds are in the case and it is closed.
- Place the case on the pad/dock aligning with the coils.
- Check the LED lights on the front of the charging case.
- Wait for the earbuds to fully charge without interrupting.
Once charged wirelessly, the TOZO T-model wireless earbuds can offer up to 10 hours of playtime on a single charger and a total of 45 hours with the charging case.
The rechargeable TOZO case can be recharged from 0% to 100% in less than 1.5 hours while placed on the pad.
Important: Check for obstructions on the charging surface, and do not interrupt the charging!
2. Clean the Charging Port
The TOZO earbuds won’t charge due to an obstructed charging port of the case.
A potential blockage will prevent the charging case from receiving power externally, preventing the earbuds from being charged while in contact with the electrical poles.
So, the next step is to conduct general maintenance of the charging case’s port and eliminate any obstructions or dust accumulation impacting the charging.
Here’s how to clean the charging port of TOZO earbuds in easy steps:
- Turn off the buds and remove them from the charging case.
- (Type 1) Use a soft-bristled brush to remove all visible dust.
- (Type 2) Use a toothbrush to scrub the debris from the case.
- (Type 3) Use a dry cotton swab to absorb the port moisture.
- Reinsert the earbuds back into the case and attempt charging.
Warning: Do not reconnect the TOZO earbuds until the charging case is fully dry!
3. Test the Voltage of Your Case
There’s a chance that the TOZO charging case cannot supply the earbuds with enough power for optimal performance.
So, by testing the electrical poles of the cases with a Multimeter, it will be possible to detect issues with the charging case and rule out potential solutions.
Here’s how to test the charging case of the TOZO earbuds via Multimeter:
- Set the Multimeter to the “A/C” or “D/C” voltage option.
- Ensure the multimeter leads are connected to the ports.
- Next, open the case’s lid and remove the TOZO earbuds.
- Connect the multimeter probes to the polarity contacts.
- There are two possible outcomes:
- No readings or infinite readings mean that the case is out of charge.
- The charging case is working well if you see 3.7V or boosted up to 5V.
When checking for continuity, a beep or a low resistance reading indicates that there is a proper electrical connection within the circuit board of the case.
4. Factory Reset the TOZO Earbuds
If the charging case works, but the TOZO earbuds are not charging, it may be a software issue!
By factory resetting the earbuds, all equalizer, pairing, and device settings will be erased, restoring the default functionality of the product.
So, the next step is to uncover how to force a complete factory reset on the earbuds and initially undergo the setup procedure of the device.
Follow these steps to perform a factory reset on the earbuds:
- Place the TOZO earbuds inside the charging case.
- Locate the action button on the back of the case.
- Press and hold the button for up to 10 seconds.
- Wait for the LED lights to turn on and flash rapidly.
- Eject the earbuds from the case and turn them on.
If the factory reset did start successfully, you will notice a rapid blinking of the LED light on the frontal part of the charging case.
Do not remove the earbuds from the case while the light is still off, or the factory reset will be canceled.
Note: Repeat the reset procedure if the LED light does not flash!
5. Charge the Case Externally (Pro-Tip)
An unusual solution for the charging issue of the TOZO earbuds is to connect the case to an external power supply.
Any external charging may sound absurd when discussing earbud technology, but it is possible if you have the correct equipment and appropriate instructions.
What Do I Need for Charging Earbuds Externally?
Here’s what the external charging of the TOZO earbuds requires:
- Two wires, one of which will be negative and one positive.
- A fully functional double-sided battery as a power supply.
Follow these instructions to deliver the power supply to TOZO externally:
- First, remove the TOZO earbuds from the charging case.
- Connect and secure the wires with the external battery.
- Open the TOZO case’s lid and locate the charging poles.
- Gently lead and touch the poles with the battery wires.
- Wait 15 minutes while the wires are charging the case.
For the procedure to work, the wires must remain in contact with the earbuds’ charging poles inside the case.
To secure the wires, cover them on the surface using isolation tape and keep your invention as a backup charging method.
If this method charges your earbuds, you have no choice but…
6. Replace the Charging Equipment
A fault with the charging equipment of TOZO will prevent the earbuds and the charging case from achieving optimal electrical supply.
This is why, after all the solutions, it’s time to consider buying a replacement, which is the solution that helped most people with the same TOZO charging fault.
How to Replace the TOZO USB Type-C Charging Cable?
- Disconnect the USB type-C cable from the adapter of the TOZO earbuds.
