C13_vs_C15 power cords

Navigating the vast sea of power cords can feel like deciphering hieroglyphics. Fear not, fellow tech sleuths! This blog post dives deep into the seemingly subtle differences between two common players: the C13 and C15 power cords. We'll equip you with the knowledge to confidently choose the perfect plug for your power needs.

Unmasking the IEC:

Before we plunge into the C13-C15 duel, let's understand their lineage. IEC, the International Electrotechnical Commission, lays down the global standards for these cords. Think of them as the power cord whisperers, ensuring compatibility and safety across borders.

The Shape-Shifters:

C13 and C15 power cords, at first glance, appear like fraternal twins. But a closer look reveals the telltale signs of their individuality:

  • The Notch:

    C15 flaunts a distinct groove opposite the grounding pin, absent on its C13 sibling. This seemingly minor detail dictates their compatibility.
  • Temperature Rating:

    C15 boasts a superior heat tolerance, reaching a sizzling 120°C. C13 power cords, on the other hand, maxes out at a respectable 65°C.

Strength and Stature:

These differences translate into distinct areas of application:

  • C13:

    The lightweight champion. Think personal computers, monitors, and and printers – everyday devices humming along at lower temperatures.
  • C15:

    The heavyweight contender. Built for high-voltage heroes like electric kettles, server rooms, and PoE switches that generate significant heat.

Advantages and Disadvantages:

No cord is perfect, and understanding their quirks is key:


  • Advantages: More common, readily available, and kinder to your wallet.
  • Disadvantages: Lower temperature rating limits its application and it may not fit into C16 outlets.


  • Advantages: Handles high temperatures like a champ, compatible with C14 outlets.
  • Disadvantages: Less common, potentially pricier, might be overkill for low-heat devices.

FAQ Roundup:

    Can I use a C13 for my electric kettle?

Not recommended. High heat can damage the cord and pose safety risks. Stick to C15 for such appliances.

    Which cord is safer? 

Both are safe when used within their respective temperature limitations.

    Where can I buy these cords?
