- Unplug When Not in Use: Unplug the charger from the wall when it’s not in use to prevent potential energy wastage and reduce the risk of overheating.
- Avoid Extreme Temperatures: Do not expose the charger to extreme temperatures, both hot and cold, as this can affect its performance and safety.

Maintenance
- Cable Care:
- If your charger has a detachable USB cable, inspect the cable for wear and tear. Avoid bending or twisting the cable excessively, as this can lead to cable damage.
- Store the cable neatly and avoid tangling, as tangled cables can lead to damage over time.
- When not in use, unplug the charger from the wall outlet to prevent unnecessary wear on the cable.
- Cleanliness:
- Keep the USB ports clean and free from dust and debris. Use compressed air or a soft brush to gently remove any dirt or lint from the ports. Be cautious not to damage the pins within the USB port.

- Proper Unplugging:
- When unplugging the charger from the wall outlet or device, pull it out by the plug, not the cord, to prevent damage to the cable.
- Replace Defective Parts:
- If you notice any defects, such as loose components or malfunctioning parts, contact the manufacturer or replace the charger with a new one.

- Ensure the charger remains dry at all times. Do not expose it to water or moisture, as this can lead to electrical shorts and pose safety risks.

Troubleshooting
- Check the Power Source:
- Ensure that the charger is plugged into a functioning electrical outlet or power source.
- Try plugging another device into the same outlet to confirm that the outlet is working.
- Inspect the Charger and Cable:
- Examine the charger for any visible damage, such as frayed cables or bent prongs.
- Check the USB cable for any damage, including bent connectors or exposed wires.
- Test with Different Devices:
- Try charging multiple devices with the charger to determine if the issue is device-specific.
- Attempt to charge a different device with the same charger and cable to see if it works.
- Clean the Charging Port:
- Sometimes, dust or debris can accumulate in the charging port of your device. Gently clean the charging port with a can of compressed air to remove any obstructions.
- Use a Different Cable:
- The issue may be with the USB cable rather than the charger itself. Try using a different USB cable to charge your device.
- Perform a Hard Reset (for mobile devices):
- If your smartphone or tablet is not charging, perform a hard reset by holding down the power button for an extended period (often around 10-15 seconds) to force a restart.
- Check for Compatibility:
- Ensure that the charger is compatible with your device. Some chargers may not provide enough power for certain devices.
- Inspect for Overheating:
- If the charger becomes excessively hot when in use, unplug it immediately. Overheating can indicate a problem with the charger or the device being charged.
- Check for Short Circuits:
- Be cautious about any unusual smells or visible smoke coming from the charger or device. Unplug the charger immediately if you detect any of these signs.
- Contact the Manufacturer:
- If none of the above steps resolves the issue, consider reaching out to the manufacturer’s customer support for further assistance. The charger may be covered under warranty.
- Replace the Charger:
