Full specifications

Compatibility — which laptops does this fit?

This 240W Dell charger is the OEM-spec power adapter for:

Wattage and connector are the two factors that decide compatibility. The 7.4mm × 5.0mm barrel with center pin connector physically matches only the listed models — do not force it into a different-size port. If you have a related but different model, WhatsApp 0314 4000131 with the exact spec sticker text and we'll confirm before you buy.

What's in the box & build quality

Every charger we ship includes the brick-to-laptop cable (fixed), the Pakistan 3-pin C5 'mickey-mouse' wall cord, and a soft pouch for travel. Build quality on this Dell unit is exactly what came with the laptop new — same chassis injection, same internal magnetic shielding, same cable strain-relief.

What you get

• 1× Dell 240W adapter brick
• 1× Pakistan/UK 3-pin AC cord
• 30-day check warranty card

Real-world use — what to expect

Plug it in and the laptop charges at full speed: 0-50% in about 35-45 minutes on most modern Dell machines, full charge in 1.5-2 hours. The brick warms up to 40-45°C under load — that's normal for a switching power supply, not a defect. The white LED on the tip turns on the moment AC is connected, so you have instant visual confirmation the brick is alive even if the laptop battery is fully drained.

Performance under heavy loads

Gamers and professionals running CPU/GPU-intensive tasks will appreciate the steady power delivery. The 240W rating ensures your Alienware m15 R6 or Precision 7550 never throttles due to insufficient power during gaming, rendering, or multitasking. Bench-tested units guarantee clean DC output with minimal ripple — critical for sensitive laptop components.

Why choose this genuine Dell charger over third-party alternatives?

Third-party chargers often skimp on safety certifications and voltage regulation. A genuine Dell adapter includes overcurrent, overvoltage, and short-circuit protection. At N.N Laptops, we only stock authentic units that have been bench-tested, so you get the same reliability as the charger that came in the box. The price in Pakistan 2026 for this Dell Original 240W Charger for Alienware m15 R6 / Precision 7550 (7.4mm) is Rs. 13,799 — a small investment for genuine OEM performance.

How to verify you've got the right charger

Three checks before you buy:

1. Wattage

Look at the sticker on the bottom of your current charger — if it says 240W, you're matched. A higher-wattage Dell charger is also safe (laptop only draws what it needs); a lower-wattage one will run the laptop but won't charge under heavy load.

2. Connector size

Use a calliper or compare to the sample photo. 7.4mm × 5.0mm barrel with center pin is the only fit — don't force a wrong-size pin.

3. Voltage

Must be 19.5V. Never use a Dell charger from a desktop or printer — those are 12V DC and will damage the laptop board.

Frequently asked questions

Can I use a higher-wattage charger instead?

Yes, higher wattage is safe as long as the voltage matches. A 265W or 285W Dell brick with the same 7.4mm × 5.0mm barrel with center pin works fine and will not damage the laptop. The laptop only draws what it needs — extra headroom helps for fast-charge mode and heavy GPU loads.

What about the new USB-C version — should I switch?

If your laptop has a Thunderbolt or USB-C charging port (most Dell models from 2019 onwards do), USB-C PD is the future-proof choice — you can charge from any compatible 65W+ brick, phone bank, or hub. For older slim-tip / barrel models, stick with the original-style charger listed here.

Does the charger include the wall cable?

Yes. Every charger ships with the Pakistan 3-pin C5 (mickey-mouse) AC cable to the wall. The brick-to-laptop side is a fixed cable for slim-tip and barrel models, and a detachable USB-C cable on USB-C models.

Is this an original or compatible charger?

Both options come through our stock. This unit is a genuine Dell pull-out from working laptops, fully bench-tested for output voltage stability, ripple, and protection circuits. We also stock high-grade compatible versions if budget is tight — just tell us on WhatsApp 0314 4000131 which you prefer.
