The charger's quality is evidenced by certifications: CE, ROHS, and FCC, along with rigorous quality control to prevent defects.
**Top Quality Features:**
- **Temperature Resistance:** The influence of high and low temperatures on the protection circuits and electrical parameters of the charger is tested.
- **Electrical Testing:** Ensures correct electrical connections between individual components of the charger.
- **Short Circuit and Overvoltage Testing:** Assesses the response of the charger's protection circuits to a short circuit or sudden voltage surge simulated by a high-voltage pulse at the charger input.
- **Final Test:** The charger's output voltage level is tested under an hour of continuous load.
**Includes:** Power cord, warranty card, and user manual.
**How to Select the Right Charger:**
- DC power parameters are generally indicated on a sticker under the laptop labeled as INPUT.
- The charger's **voltage (V)** should match the value on the laptop.
- The **current (A)** should be equal to or higher than the laptop's requirement, indicating the maximum current allowed for the charger; the laptop decides the load.
- **Power (W)** is the result of voltage multiplied by current.
- **Plug shape and size** should be compared with the offered item photo and the plug dimensions provided in the description; you can also check with the charger manufacturer's database.
