1 Check the original adapter's specifications: Look for the details on your device's original adapter, such as input voltage (AC voltage), output voltage, output current (or power), and connector type (e.g., round DC connector, USB-C, etc.). This information is typically printed on the adapter itself or found in the 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 Confirm that the connector type is compatible with your device’s charging port.
A: Our adapters are engineered with safety in mind and include several key protective features:
1 Overcurrent protection: Automatically disconnects power when the current exceeds safe levels, preventing overload.
2 Short-circuit protection: Instantly cuts off power if a short circuit is detected, protecting both the device and the adapter.
3 Overvoltage protection: Safeguards your device from excessive voltage that could lead to damage.
4 Undervoltage protection: Prevents the adapter from supplying power when the voltage is too low, ensuring the safety of your device.
5 Overheat protection: A smart temperature control system monitors heat levels and reduces power or shuts off the adapter to prevent overheating.
A: As long as the replacement adapter matches your device’s specifications, it won’t cause any damage. Our adapters undergo thorough quality checks and safety testing to ensure they deliver stable voltage and current, fully complying with international safety standards.
