1.Please confirm that the power of the USB-C power supply used is greater than the power being charged, otherwise it will fail to charge or intermittent charging. If the above problems occur, please update your power supply in time. 2. The use of this product only induces the USB-C power output suitable for the charging voltage of the notebook, and cannot generate power by itself, so the final output power is determined by the power used. 3. If you want to ensure the power of the notebook you use, please refer to the original charger voltage multiplied by the current (20V voltage * 3A current = 60W power). Compatible must be greater than or equal to this power for normal use, otherwise it cannot be purchased and used.
