First, verify that you are using either the original ASUS charger included with your device or a certified charger whose output power meets or exceeds the device’s recommended charging wattage. Learn more about How to check the power adapter specifications and the recommended wattage.
The exclamation mark and warning message are system alerts indicating that the wattage of the current charging equipment may be insufficient. This can result in reduced device performance, suboptimal charging efficiency, and—when using the device while charging—continued battery drain.
To avoid compromising your experience, it is recommended that you use the bundled ASUS charger whenever possible. If the warning persists even with the original charger, please visit an ASUS service center for inspection.
If your ASUS product supports both DC-IN power (via an AC adapter) and USB Type‑C charging, please note the following:
Even if your USB Type‑C charger meets the model’s recommended USB Type‑C rated wattage, the system may still display a 「Slow Charger」 message if that wattage is lower than the AC adapter’s recommended wattage. This is normal behavior.
