1. Confirm whether to use wireless or wired charging 2. If wired charging fails: a. Replace the cable for testing b. Restart iWatch/Bluetooth headset If wireless charging fails: a. Confirm the switch is turned on (double-click the button) b. There is no foreign object blocking the contact position c. The wireless contact position should be in the center of the device as much as possible
1. The power bank may have low output power: Check the output power of the power bank (usually expressed in amperes [A] or watts [W]). If the power bank has low output power, it will result in slower charging speed. The solution is to choose a power bank with higher output power. 2. Charging cable quality problem: Using a low-quality or damaged charging cable will also affect the charging speed. Try to use a manufacturer-recommended or high-quality charging cable to improve charging efficiency. 3. Interface compatibility: Some power banks have different output powers on different interfaces (such as USB-A, USB-C, Micro-USB). Using the wrong interface may result in slower charging speed. Make sure to use the correct interface and cable. 4. Mobile phone charging method: Some mobile phones support fast charging technology (such as Quick Charge, Power Delivery), but both the power bank and the charging cable need to support the corresponding fast charging protocol. Check whether the power bank supports the fast charging protocol of your mobile phone and use a compatible cable. 5. Low power of the power bank: When the power of the power bank is too low, its output power may weaken, resulting in slower charging speed. Make sure your power bank has enough power, preferably above 50%. 6. Charge while using: During charging, if the phone has a large number of background applications running or is using high-power consumption functions (such as games, video playback, etc.), the charging speed will also be affected. Turning off unnecessary applications and functions can improve charging efficiency.
1. Charger problem: Output power: Make sure you are using a high-power charger. Many power banks support fast charging, but the premise is that you need to use a charger that supports fast charging. For example, use a charger with an output of 5V/2A or higher power instead of a 5V/1A charger. Quality: Use a high-quality charger. Poor-quality chargers may not provide a stable output current, resulting in inefficient charging. 2. Charging cable problem: Cable quality: Use a high-quality charging cable. Poor-quality or damaged charging cables will slow down the charging speed. Make sure the charging cable is not damaged and matches the power bank well. Wire internal resistance: Cables that are too long or have high cable internal resistance will also affect the charging speed. Try to use a shorter cable designed for fast charging. Charging interface: Interface type: Some power banks support multiple interfaces (such as Micro-USB, USB-C, etc.). Use an interface that supports fast charging and a matching charging cable. Loose plug: Make sure the connection between the charging cable and the charger and power bank is firm and stable, and not loose. 3. Charging environment: Temperature: Make sure to charge the power bank at normal ambient temperature. Too high or too low temperature will affect the charging efficiency. Clean interface: Keep the power bank and charging cable interface clean. If there is dust or foreign matter, it may affect the contact and charging efficiency.
1. If the problem occurs when the battery is charging itself, try using another cable and another charger. 2. If the problem occurs when charging other devices using the device C port, try using another cable and another device. Sometimes this helps. 3. If the heating problem occurs when wirelessly charging other devices, first explain that general charging heating is normal, and then try the following tips: ①. If you are running a large program or there are many background programs, it will be a little hot even if you leave it there to charge ②. The wireless charging process itself generates heat. If the ambient temperature is high, it is not conducive to the heat dissipation of the device. Try to perform wireless charging in a well-ventilated and moderately warm environment. ③. Is there a case? Remove the case and charge it for comparison ④. Wait until the temperature drops, use our power bank to charge other devices for testing If the user says it is still very hot, guide the return (note to keep the analysis)
