Don’t try to fix your frayed cable—prevent the damage in the first place

Laptop chargers are essential, but their constant use leads to wear and tear. Frayed cables are not just unsightly; they're dangerous. This guide explains how to handle damaged chargers and prevent future problems.

The Dangers of Frayed Cables

Worn chargers are visually unappealing, but the risks are substantial. According to Arthur Shi, a technical writer at iFixit, the dangers affect both the user and the device. Electrocution is a possibility, though unlikely, if the AC wire (the part that plugs into the wall) is frayed. Immediately discontinue use and replace a charger with a damaged AC wire.

Frayed DC wires (connecting to your laptop) pose a less immediate, but still significant risk. While a temporary fix might seem possible, repeatedly manipulating the damaged area weakens the wires further. Contact between frayed wires can damage the charger's circuitry or the device itself, potentially frying the charging port or causing overcharged batteries to explode. Discard or responsibly recycle damaged chargers.

Repairing a Worn-Out Charger?

While tempting to use duct tape, this is not a safe solution. While skilled individuals can repair cables, the Electrical Safety Foundation International advises against it. Considering the relatively low cost of replacements, purchasing a new charger is generally recommended.

However, avoid cheap, low-quality third-party chargers. Shi warns that these often lack the safety features of reputable brands, especially crucial for laptops with complex charging circuitry. Invest in a genuine charger for your laptop. Smartphone chargers are less complex, making reputable aftermarket options (like Anker) acceptable alternatives.

Maintaining Cable Condition

To extend the life of your charger, consider these steps:

• Invest in durable cables: Braided cables, like Anker's Powerline , offer superior durability.
• Reinforce weak points: Use Sugru, a moldable silicone glue, to reinforce the joints between the cable and connectors before they fray. This is especially useful for first-party laptop chargers that may be less robust.
• Proper handling: Avoid yanking on the cord; pull from the base of the plug. Avoid sharp bends, especially near the power brick, when wrapping the cable.
• Use the "roadie wrap" method: This prevents repeated bending in the same direction. A video demonstrating this technique is included below.

The video showcases a "roadie wrap" for AV cables; the same technique applies to chargers. Careful handling significantly extends cable lifespan.
