2. Careful Handling:
   Careful handling emphasizes the importance of avoiding unnecessary strain on the charger’s cables and connectors. Tugging or bending cables can damage internal wires, leading to poor performance or failure. The University of Illinois suggests that using the charger with gentle motions, instead of yanking or pulling, can extend its life. For instance, neatly coiling the cable can prevent kinks and wear on the outer casing.

3. Regular Inspection:
   Regular inspection involves monitoring the charger for signs of wear, damage, or overheating. Checking for frayed wires, loose connections, or discoloration indicates potential issues. An article in Wired highlights that proactively identifying problems can prevent complete failure. For example, if a charger smokes or feels excessively hot during use, it should be replaced immediately to avoid safety hazards.

4. Using Compatible Devices:
   Using compatible devices means ensuring the charger matches the specifications required by the device being charged. Mismatched voltage or amperage can lead to overheating and shorten the charger’s lifespan. The Consumer Product Safety Commission warns that using chargers with different electrical ratings can cause damage to both the charger and the device. Therefore, checking the device’s user manual for compatibility before use is essential.
