Step 2: View Battery Usage
- Scroll down to the “Battery usage” section
- Click on the time period dropdown to select “24 hours” or “7 days”
- Review the battery usage graph to identify charging periods
Step 3: Check Battery Information
- Look for battery percentage changes during charging periods
- Note the time taken to charge specific percentages
- While this doesn’t show exact wattage, it provides charging efficiency insights
Method 2: Using Device Manager
Device Manager can provide information about your power adapter and charging capabilities.
Step 1: Open Device Manager
- Right-click the Start button
- Select “Device Manager” from the context menu
Step 2: Locate Battery and Power Devices

Step 3: Monitor Charging Rate
- Look for “Charge Rate” or “Current Capacity” values
- Monitor changes in real-time while your device is plugged in
- Note the charging wattage displayed in the interface
Method 4: Using Command Prompt
Command Prompt offers another built-in method for checking power-related information.
Step 1: Open Command Prompt
- Press Windows key + R
- Type “cmd” and press Ctrl + Shift + Enter to run as administrator
- Confirm UAC prompt if it appears
Step 2: Generate Energy Report
- Execute the following command:
powercfg /energy
- Wait for the analysis to complete (approximately 60 seconds)
Step 3: Review the Energy Report
- The command generates an HTML report saved in the System32 folder
- Navigate to C:\Windows\System32\energy-report.html
- Open the file in a web browser
- Look for power efficiency analysis and charging-related warnings
Method 5: Using Windows PowerShell
PowerShell provides the most accurate built-in method for checking charging wattage in Windows 11.
Step 1: Open PowerShell as Administrator
- Press the Windows key + X to open the Power User menu
- Select Windows Terminal (Admin) or PowerShell (Admin)
- If prompted by User Account Control, click Yes to proceed
Step 2: Execute the Battery Report Command
- Type the following command and press Enter:
powercfg /batteryreport
- This generates a comprehensive battery report saved as an HTML file
Step 3: Locate and Open the Battery Report
- The command will display the file path where the report is saved (typically in your user folder)
- Navigate to the specified location using File Explorer
- Double-click the “battery-report.html” file to open it in your default web browser
Step 4: Analyze Charging Information
- Scroll down to the “Recent Usage” section
- Look for entries showing “AC” (alternating current) which indicates charging periods
- The report shows power consumption patterns but may not display real-time wattage
Step 5: Use Advanced PowerShell Commands For more detailed real-time information, execute:
Get-WmiObject -Class Win32_Battery | Select-Object EstimatedChargeRemaining, BatteryStatus
This command provides current battery status and charge level.
Interpreting Charging Wattage Results
Understanding your charging wattage results is crucial for proper analysis:
Normal Wattage Ranges:
- Ultrabooks: 45-65 watts
- Standard laptops: 65-90 watts
- Gaming laptops: 90-240 watts
- Workstations: 150-330 watts
Factors Affecting Charging Wattage:
- Battery charge level (higher wattage when battery is low)
- System load (CPU and GPU usage affects available charging power)
- Temperature (thermal throttling can reduce charging rates)
- Power adapter specifications (maximum wattage output)
- USB-C Power Delivery negotiations
Troubleshooting Low Charging Wattage
If you discover lower-than-expected charging wattage:
Check Power Adapter Compatibility:
- Verify your adapter meets your laptop’s power requirements
- Ensure proper connection to both laptop and wall outlet
- Test with the original manufacturer’s adapter if using a third-party option
Update Power Management Drivers:
- Use Device Manager to update battery and power management drivers
- Check your laptop manufacturer’s website for latest power management software
Adjust Power Settings:
- Navigate to Power Options in Control Panel
- Select “High Performance” or “Balanced” power plans
- Avoid “Power Saver” mode while charging for optimal rates
Conclusion
