2 Pack Apple MFi Certified iPhone Charger Cable 6Ft, Lightning to USB Cable 6 Foot, Fast Charging Long Chargers for iPhone 14/13/12/11/ X/XS/XR/8/7/6/SE Plus Pro Max Mini

The iPhone charger cable we sell is a MFi Lightning cable. You can log in to the official Apple MFi Accessories and search our brand "TUMABER" to confirm that this cable is Apple MFi certified.

When the phone is charging, it is normal for it to generate some heat. The main reasons for this heat are as follows:

1. The charging speed will be faster when the phone power is low, as the wall charger will output 9V high voltage, and the phone will generate heat because of the voltage converting process.

2. There are too many programs running in the background of the phone, causing the phone to run at a high load and generate more heat.

Recommendations to prevent overheating:

1. Clean up the running programs with high power consumption in the background in a timely manner.

2. Don't use the phone while it's charging with low power, otherwise the phone will be in a high load state.

The error message "This accessory may not be supported by device" may appear if you're using a non-Apple wall charger or if there is poor transmission. Even when using an Apple accessory, this error can also happen due to firmware problems with iOS. The causes of this problem may include:

1. The device's lightning port contains impurities such as fiber and debris, resulting in poor transmission.
2. The voltage of the wall charger is too low or unstable, resulting in insufficient power supply.
3. The lightning end is corroded/stained, resulting in poor transmission.
4. Circuit logic problems/system problems with the charging equipment.
5. The chip or mainboard of the cable is damaged.

Solutions to try:

1. Use a pushpin to clean out the pocket lint or debris from the charging port.
2. Wipe the Lightning end with a tissue to remove dirt and oxidation marks.
3. Use the original charger or an MFi charger, as some laptop USB output ports may have insufficient power output.

The new C89 Connector is silver, using a new electroplating process to effectively prevent liquids such as sweat from corroding. It supports 2.4A fast charging and 480Mbps 2-in-1 data syncing, making it a safe and fast iPhone charging and data transfer cable.

The cable uses high-purity, thickened copper wire, which ensures more stable transmission and charging. The connector adopts laser welding technology, making the connection more firm and less likely to break. The cable joint has passed 10,000+ bending tests and will not break easily when bent.

This Apple MFi Certified charger cable is compatible with iPhone 12, 11, XS, XR, X, 8, 7, 6, 5, and various iPad and iPod models. The MFi Certified chip ensures safe and effective current output for the device, and the high-quality copper wires support fast charging and data transmission.
