Laptop power adapter Energy4U PA36 — 180W, 19V, 9.5A, 2.5mm connector

The Energy4U PA36 laptop power adapter delivers 180W of continuous power at 19V and 9.5A through a 2.5 mm DC connector. It is intended as a replacement or spare charger for laptops that accept a 2.5 mm plug and the specified voltage and current. The adapter supplies stable output for charging battery packs and powering laptop operation, and incorporates built-in protections to help guard against overcurrent and short circuits where applicable. Its compact design makes it suitable for use at home, in the office, or while traveling.

Advantages

The adapter provides a high 180W output suitable for power-hungry laptops that require up to 9.5A at 19V. A standardized 2.5 mm DC plug ensures a secure physical connection with compatible laptop power inlets. Built-in safety features reduce the risk of damage from electrical faults by providing protection against overcurrent and short circuits where implemented. The adapter’s form factor and cable length are designed to balance portability and everyday usability.

Suitable for

• Replacing a lost or damaged 19V laptop charger with a 2.5 mm plug
• Keeping as a spare charger for home, office, or travel
• Powering laptops that require up to 19V and 9.5A for normal operation
• Use where a stable 19V supply is needed for peripherals or docking solutions that accept a 2.5 mm input

Key specifications

• Output power: 180 W
• Output voltage: 19 V
• Output current: 9.5 A
• Connector type: 2.5 mm DC plug
• Intended use: laptop power and charging
• Protections: overcurrent and short-circuit protection where implemented

How to use

Confirm that your laptop accepts a 19V input and that the device’s recommended current does not exceed 9.5A. Connect the adapter’s 2.5 mm plug firmly into the laptop’s power inlet and plug the adapter into an appropriate AC mains socket. When first using the adapter, monitor the laptop for normal charging behavior and ensure the adapter does not become excessively hot during operation. If any abnormal behavior occurs, disconnect the adapter and inspect cables and connectors for damage before further use.

Usage recommendations

Use the adapter only with devices that match the specified voltage and connector type. Avoid bending the cable sharply near the connector, keep the adapter in a well-ventilated location during use, and disconnect from mains when not in use for extended periods. If the laptop requires a different connector size or higher current, select a compatible adapter instead of attempting to force a connection.
