HNHTKJ 240W Charger for Dell Alienware & Precision 19.5V

HNHTKJ 240W AC Adapter is a high-capacity replacement charger designed to power Dell Alienware and Precision mobile workstations with a 19.5V 12.3A output and a 7.4 x 5.0mm power tip.

This compact power brick supplies the extra wattage gaming laptops and mobile workstations require to run at full speed and charge under load. Built to match OEM voltage and connector size, it replaces older or lost adapters and supports international voltages for travel. The package includes the charger and a detachable power cord, and the total cable reach of roughly 10 feet gives flexible placement whether you’re gaming at a desk or working in a studio.

How does the adapter perform for gaming and heavy workloads?

With a rated 240 watts, this adapter delivers sufficient sustained power for GPU- and CPU-intensive tasks while also charging the battery. It’s engineered to support peak system demand so you can game, render, or run simulations without throttling from low power.

• High output: 19.5V at 12.3A to handle demanding power draws
• Stable voltage delivery reduces the chance of power sag under load
• 7.4 x 5.0mm barrel ensures a secure physical and electrical connection

What about safety, travel compatibility, and cable length?

The adapter accepts 100–240V AC input at 50–60Hz, so it works worldwide with the appropriate plug. Safety features are built into the adapter circuitry to protect against common risks, and the included cables give generous reach for flexible setups away from the wall outlet.

• Universal AC input: 100–240V, suitable for international travel
• Included detachable mains cord and power brick for easy packing
• Total length ≈10 feet (6 ft charger cable + 4 ft power cord) for flexible placement

How easy is installation and what comes in the box?

Installation is plug-and-play: attach the power cord to the brick, connect the barrel tip to your laptop, and plug into AC power. The kit contains what you need to get started right away and is a straightforward replacement for original Dell adapters with the same connector and rating.

• In the box: 1x HNHTKJ 240W charger and 1x detachable power cord
• Pre-wired barrel tip (7.4 x 5.0mm) for direct laptop connection
• No drivers or software required — full operation immediately after connection

Who is this for: This HNHTKJ 240W AC adapter is intended for owners of Dell Alienware and Precision laptops that require high-wattage external power — gamers, creative professionals, and engineers who need reliable wall power to maintain maximum performance. It’s also useful as a spare or travel replacement for technicians and students who move between locations and need consistent power delivery without carrying the original OEM brick.
