Replacement Adapter for Apple MC6U4LL/A (70W)

1 Check the original adapter's specifications: First, locate the information on your device's original adapter, including input voltage (AC voltage), output voltage, output current (or power), and connector type (such as a round DC connector, USB-C, etc.). This information is usually printed on the adapter itself or in the accompanying manual.
2 Match the voltage and current/power: Ensure that the replacement adapter has the same output voltage as the original or does not differ by more than 1V. The current (or wattage) can be slightly higher but should not be lower to maintain proper charging and protect the device.
3 Check the connector: Verify that the connector type is compatible with your device’s charging port.

A: Our adapters are designed with your safety in mind, offering several protective features, such as:
1 Overcurrent protection: Automatically disconnects the power supply when the current exceeds a safe limit, preventing overload.
2 Short-circuit protection: Immediately halts the power output if a short circuit is detected, safeguarding your device and the adapter.
3 Overvoltage protection: Shields your device from excessive voltage that could cause damage.
4 Undervoltage protection: Ensures the adapter does not supply power when the voltage is too low, preventing harm to the device.
5 Overheat protection: An intelligent temperature control system monitors heat levels and reduces power or shuts off the adapter if it gets too hot, preventing overheating.

A: As long as the replacement adapter matches your device’s specifications, it shouldn’t cause any harm. All our adapters undergo rigorous quality checks and safety tests to guarantee that they deliver consistent voltage and current, and comply with international safety regulations.
