Is it dangerous to leave a plugged in charger without a device?

**However**, problems arise in certain cases:

* **Cheap, knockoff, or damaged chargers** are more likely to overheat, short-circuit, or fail.
* Chargers in **poorly ventilated areas** (like under pillows or blankets) can overheat.
* **Older chargers** may not have updated safety standards.

So while rare, the **risk isn’t zero** — especially if the charger is low-quality or left plugged in for extended periods.

## 💡 How Much Energy Does It Waste?

A single unused charger draws about **0.1 to 0.5 watts per hour** — not much on its own. But multiply that by every charger in your house, 24/7, and over time it can add up.

It may only cost you a few dollars a year, but if millions of people leave theirs plugged in constantly, the environmental impact becomes real.

## ✅ So, What Should You Do?

* **Unplug chargers when not in use**, especially if you’re leaving the house or going to bed.
* **Avoid cheap or counterfeit chargers** — always buy from reputable brands.
* **Check for wear and tear** — replace frayed cables or loose adapters.
* Consider **smart power strips or outlets** that cut power automatically.

## 🧠 Final Verdict

Leaving a charger plugged in without a device isn’t an immediate danger — but it’s not entirely risk-free either. The smarter, safer habit? **Unplug it when you’re done**. It protects your devices, your home, and even helps the planet a little.
