Common Causes for Overheating

Sometimes, chargers get hotter than they should. Unfortunately, there isn’t a single culprit—several factors contribute to the overheating mystery.

  • High Ambient Temperatures

Is your charger lounging in the sun? Ambient temperature can turn a normally warm charger into a hot one. Electronics prefer cooler environments, so keep them out of the heat as much as you can.

  • Poor Ventilation

Stifled airflow is a no-no. Chargers need to breathe too, so make sure yours isn’t suffocating under a pile of papers or stuffed in a couch cushion.

  • Using the Laptop While Charging

We’re all guilty of using our laptops while they charge. It’s convenient, but it also means your charger is working double-time, wrestling with powering up the battery and running your cat video marathons at the same time.

  • Faulty Hardware

A damaged or low-quality charger can also get unduly hot. Watch out for frayed cables or a charger that feels too light—it might be a sign of inferior design or damage.

Potential Risks of Overheating

When a charger starts resembling a hot potato, it’s not something to ignore. The consequences of an overly warm charger can run from mild to severe.

  • Battery Damage

One thing for sure, batteries and excessive heat don’t mix well. Heat can degrade battery life over time, leaving you with a laptop that can hardly hold a charge.

  • Risk of Fire

Worst case scenario, an overheated charger can become a fire hazard. By now, everyone’s heard a tale or two about electronics gone up in smoke. Definitely not something to take lightly.
