If you have a related but different model, WhatsApp us 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 15-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. 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.

Warranty & after-sales support Every charger carries our standard 15-day check warranty — if the brick fails on first install, develops an output fault, or shows AC ripple during the test period, bring it back to the shop with the invoice for a full replacement or refund. No questions asked within the warranty window. 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 tested for output voltage stability, ripple, and protection circuits.
