How to Turn On or off PC Charging Slowly over USB Notification in Windows 11

Why This Matters

This alert is useful when you rely on third-party chargers, older power bricks, or a low-power USB port. If charging seems slower than it should be, the notification tells you right away. You don’t have to wait and watch the battery percentage. Some people find the alert distracting, for example when they deliberately use a slow port. Windows lets you turn it off.

Windows 11 build 25252 introduced this capability to warn users about underpowered connections. Later, build 26052 (in the Canary and Dev channels, which are early testing versions of Windows) updated the notification wording. If you run a regular stable release, the exact wording of the alert may differ from what you see in preview builds.

Option 1Use Settings

Turn On or Off PC Charging Slowly over USB Notification

The Settings app is the simplest way to turn this notification on or off. It works the same on Windows 11 Home and Pro, and you don't need to restart your PC. The change applies as soon as you flip the switch.

1. Open Settings. Press Win+I on your keyboard. The Settings window opens.
2. Click Bluetooth & devices on the left side. Then click USB on the right side. You should now see the USB options for your PC.
3. Use this link if you want to check or reach the same page another way:  Open USB settings
4. Turn the option On (default) or Off next to "Show a notification if this PC is charging slowly over USB." Choose what you want. The switch changes right away.
5. Close Settings when you are done.

To undo the change, repeat the same steps and set the switch back to its previous position.

If you don't see this option, your build of Windows 11 probably doesn't include it yet. The feature first appeared in build 25252, so install the latest Windows updates and check again.

Here is the short version. Press Windows + I to open Settings. Click Bluetooth & devices, then select USB. Use the switch for the slow-charging notification to turn it on or off.

Option 2Use Registry Editor

⚠️ ADMIN PRIVILEGES REQUIRED

Changes made through the Registry Editor need an administrator account. If you are signed in with a standard account, Windows asks for administrator credentials or blocks the change.

Summary

Toggling this alert takes only a few clicks within the main configuration panel. Advanced administrators can also manage this preference through the Registry Editor. For most people the Settings method is safer, because it needs no registry edits and is easy to undo.
