Charging issue

1. If the earbuds and charger case are out of battery, charge them continuously for more than 2 hours.
2. Replace the cable and charger and check if this resolves the issue.
3. Check if there is any dirt inside the earbuds' copper pillars and charging case pogo pin.
4. Ensure the earbuds are charging at a comfortable temperature (about 25°C).

If the issue persists, please contact our Customer Support.

1. Check if there is dirt inside the charging port of the case.
2. Try using another cable or charger.
3. Plug the charger in and out several times and check if it works.
4. Ensure the earbuds are charging at a comfortable temperature (about 25°C).

If the issue persists, please contact our Customer Support.

1. Check if there is any dirt inside the earbuds' copper pillars and charging casepogo pin.
2. Lightly shake the earbuds' case to ensure the earbud and pogo pin are in close contact, and try charging again.
3. Place the earbuds in the charging case and connect the charger for 10 mins, and try charging again.
4. Open the case and long-press the pair button for 10 seconds until the notification light is on; then try charging again.

When using a single USB-C port, charging can reach up to 140W. However, when multiple ports are used simultaneously, the power is redistributed, causing the charging power to be reduced. This may result in some high-power devices being unable to continue charging. For high-power devices, we recommend using a single port.

Please refer to the instruction manual included to understand the power parameters for multi-port use.

For electrical safety, the adaptor has a grounding design, so the presence of leakage current is normal. This leakage current is within standard limits and does not harm human health.

If the charging current from the USB-A port is less than 0.1A, the USB-C port automatically adjusts power distribution. If the charging current from the USB-A port is greater than 1.0A, the USB-C port automatically adjusts power distribution.

The adaptor will allocate power when multiple ports are in use. During this power distribution process, there may be a brief interruption before the charging resumes. Please refer to the user manual for more details.

Check if the socket is old or loose. If so, replace it.

Note that each adaptor has undergone rigorous safety certification and testing. The sparks do not affect product use or pose any safety risks.

The working frequency of the internal components of the power adaptor is within the audible frequency range of human ears (20 Hz to 20 KHz). People with sensitive ears may hear this noise. This can be avoided by unplugging the adaptor when not in use. Each adaptor has undergone rigorous safety certification and testing. The noise is generated by the normal operation of the product and does not affect product use or pose any safety risks.

Don't hesitate to contact us if you have any further questions.

To resolve the issue, try the below:

1) Ensure that the USB cable is properly connected and that the USB cable is not damaged.
2) Try using another adaptor to check if the problem is to do with the battery.
3) Ensure that the charging ports of the device and the charging cable are free from dirt and damage.
4) Ensure that the power of the original charger for the device is greater than 140W.
5) If the temperature of the device being charged is too high, charging may be limited. You can try to unplug the device for a short period of time or place it in a cooler environment and then reconnect the adaptor.

If the issue remains unresolved, we recommend taking your device to a service center for inspection.

To resolve the issue, try the below:

1) Ensure that the voltage in the region you are using the adaptor is compatible with the working voltage of the adaptor.
2) Ensure that the output voltage of the adaptor is compatible with the device's required working voltage.
3) Ensure that the adaptor interface is compatible with the charging cable interface.
4) Ensure that the USB cable is properly connected and that the USB cable is not damaged.
5) Try using another adaptor to check if the problem is to do with the battery.
6) Ensure that the charging ports of the device and the charging cable are free from dirt and damage.
7) Ensure that the adaptor is compatible with your device's fast charging protocol. Some devices may use proprietary charging protocols and cannot be charged with third-party adaptors.

If the issue remains unresolved, we recommend taking your device to a service center for inspection.

To resolve the issue, try the below:

1) Ensure that the fast charging protocol of your device is compatible with the adaptor. The charging power of different charging protocols can vary, and some devices may use proprietary charging protocols.
2) Ensure that the USB cable is properly connected and that the USB cable isn't damaged. If the connection is unstable, charging may be intermittent.
3) Ensure that the charging ports of the device and the charging cable are free from dirt and damage that may cause intermittent charging.
4) If the temperature of the device being charged is too high, the charging speed may be limited. You can try to unplug the device for a short period of time or place it in a cooler environment and then reconnect the adaptor.
5) If using multiple ports simultaneously, the charging power for each individual port is reduced. For instance, the maximum power for the USB A port is 10W when all three charging ports are being used. To achieve higher charging power, disconnect devices that are already fully charged.

If the issue remains unresolved, we recommend taking your device to a service center for inspection.

To resolve the issue, try the below:

1. Ensure that the device(s) you're charging don't require more than 140W. If the device's original charger is rated above 140W or if the charger is used continuously for multi-port charging, the adaptor may operate at full power for extended periods, which can cause it to heat up.
2. The adaptor converts alternating current (AC) to direct current (DC). During this process, there is energy conversion and loss. The lost energy is released in the form of heat. The adaptor also contains electronic components such as inductors and capacitors. When current flows through these components, they generate resistance, converting some of the electrical energy into heat. This is why the adaptor feels hot.

For your safety, please charge your device in a cool and well ventilated environment. If you find that the product is overheating, please stop using it immediately and contact us.
