Product information

Description

Energy4U CA18 is a compact 40 W laptop power adapter that delivers a regulated 12 V DC output at 3.3 A through a 0.7 mm barrel plug. It is designed as a replacement or spare charger for compatible laptops and portable electronics, offering stable power delivery and a lightweight form factor suitable for everyday use and travel. Before use, verify the device's required input voltage, polarity and connector dimensions to ensure compatibility.

Advantages

The adapter provides a consistent 12 V output with a maximum current of 3.3 A, supporting reliable charging and stable operation of compatible devices. Its 0.7 mm barrel plug offers a precise physical fit for devices that require that connector size. With a 40 W power rating the unit balances energy delivery and compactness, making it practical for use at home, in the office or on the go.

Suitable for

  • Replacing a worn or lost laptop charger with matching voltage and connector size
  • Powering small portable devices that accept 12 V, 3.3 A input via a 0.7 mm plug
  • Travel use when a compact, lightweight adapter is needed

Key specifications

  • Output voltage: 12 V DC
  • Maximum output current: 3.3 A
  • Power rating: 40 W
  • Connector type: 0.7 mm barrel plug
  • Output regulation: regulated DC output for stable voltage
  • Form factor: compact, lightweight adapter housing

How to use

Confirm that your laptop or device accepts 12 V input and that the barrel connector and polarity match the adapter. Connect the 0.7 mm plug firmly into the device input, then plug the adapter into an appropriate AC mains outlet. Allow the device to charge or operate as normal. Disconnect by first unplugging from the mains and then removing the connector from the device when charging is complete or when the device is powered down.

Usage recommendations

Use the adapter in a well-ventilated area and avoid covering it while in operation to prevent heat buildup. Do not use the adapter with devices requiring different voltage, higher current, or different connector polarity. Inspect the cable and connector for damage before each use and replace the adapter if any wear or defects are found.
