HP 391172-001 adapter  [65W]

① Check the original adapter information: First, find the relevant information of the original adapter of your device, including input voltage (AC voltage), output voltage, output current (or power), and interface type (such as round DC interface, USB-C interface, etc.). This information is usually marked on the adapter itself or the accompanying manual.
② Match voltage and current/power: According to the parameters of the original adapter, select an adapter with the same or compatible output voltage and current (or power). The voltage must be accurately matched, while the current (or power) can be slightly higher but it is not recommended to be lower than the original specification to ensure charging efficiency and device safety.
③ Confirm the interface type: Make sure that the interface of the selected adapter matches the charging port of your device.

We are well aware of the importance of safety, so our adapters have built-in multiple safety protection mechanisms, including but not limited to: Overcurrent protection: When the current exceeds the preset value, the power supply is automatically cut off to prevent overload. Short circuit protection: When a short circuit is detected, the output is immediately stopped to protect the circuit safety. Overvoltage protection: prevents damage to the device due to excessive voltage. Undervoltage protection: ensures that there is no wrong power supply when the voltage is insufficient, protecting the battery and the device. Overheat protection: built-in intelligent temperature control system, monitors the temperature and automatically reduces the power or shuts down the output when necessary to prevent danger caused by overheating. In addition, we also use high-quality components and fireproof materials to ensure the stability and safety of the product during long-term use. You can rest assured to use our adapters to provide safe and reliable power support for your device.

As long as the adapter matches the parameters of your device, it will usually not cause damage to your device. All our adapters undergo strict quality control and safety testing to ensure that the output voltage and current are stable and meet international safety standards.
