SKU CH-7EMK-A67YP MPN CPA09-022A

300 W AC adapter delivers 20 V at 15 A through a 4-pin connector and includes a power cord

  • Reliable power worldwide with 100-240V input range
  • High 300W output for demanding laptop workloads
  • Stable 20V 15A delivery protects connected components
  • Built-in safeguards against voltage, short-circuit and overheating risks
  • Includes power cord for immediate use

What this adapter does

The Chicony CPA09-022A delivers 20V at 15A for a total of 300W output. It accepts 100-240V input at 4.5A across 50-60Hz mains. A power cord is included in the box. This unit suits laptops that require a 4-pin barrel connector at this voltage and current.

How it fits your setup

The adapter plugs directly into the laptop’s 4-pin DC jack and into a standard wall outlet via the supplied cord. No external power brick or additional cabling is required beyond what is provided. It frees you from hunting for a matching tip or a separate mains lead. Buyers whose devices use a different connector pin count or voltage cannot use this unit.

When to choose this over a lower-wattage unit

This 300W model replaces adapters rated below 300W when the laptop’s original charger matches the 20V 15A specification. The jump is worth it if the original unit has failed, been lost, or cannot sustain full load under heavy use. It does not suit systems that demand a higher output wattage or a different output voltage.
