What’s included and how do I set it up?

The package contains everything needed to start using the adapter right away: the power brick, a detachable AC power cord, and a user manual. Setup is a simple plug-and-play process — connect the AC cord to the adapter, then plug the barrel connector into the laptop’s power jack.

• Package contents: 1 × 240W power adapter, 1 × AC power cord, 1 × user manual.

Will this charger harm my laptop if it’s more powerful than the original?

Using a higher-wattage adapter is generally safe when voltage and connector type match the laptop’s requirements — the machine will draw only the current it needs. This adapter’s smart circuitry helps ensure it supplies regulated power and only delivers higher current when the laptop requests it.

• Voltage match: 19.5V required; do not use if your laptop requires a different voltage.
• Connector compatibility is essential: confirm the 7.4×5.0mm barrel fits your port.
• Built-in protections reduce risk of electrical faults during normal use.
