Dell 240W Big Barrel Charger for Precision 7720 Workstation — genuine, tested, ready to ship
If you own a Dell Precision 7710, 7720, or 7730 — or an Alienware 15 R3 or 17 R5 — you already know the original charger is a beast. This Dell 240W Big Barrel Charger is the exact OEM unit that came with your workstation, now available at nnlaptops.com for Rs. 12,699. We've bench-tested every unit for stable voltage, low ripple, and fully functional protection circuits — so you can plug it in and get back to work immediately. Whether you're in Lahore, Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, Peshawar, or Sialkot, we ship nationwide via TCS or Leopards, and offer same-day delivery in Lahore.
This charger outputs a solid 19.5V at 12.3A through the 7.4mm × 5.0mm barrel connector — the wide, keyed tip that locks into your Precision or Alienware. It's the correct 240W power supply for heavy-duty tasks: rendering 3D models, running multiple VMs, or crunching large datasets. The laptop charges from 0-50% in about 35-45 minutes under moderate load, and fully refills in 1.5-2 hours. The brick does get warm (40-45°C) under sustained load — that's normal for a 240W switching supply, not a defect. The white LED on the tip lights up the moment you plug in AC, so you know instantly the brick is alive even if your battery is dead.
Compatibility and how to verify yours
This Dell 240W adapter is the direct replacement for: Precis ion 7710, Precision 7720, Precision 7730, Alienware 15 R3, Alienware 17 R5. Connector size is 7.4mm × 5.0mm — the larger barrel used on Dell workstations and high-end Alienware. Do not force a smaller tip. If your current charger says 240W and has the same barrel shape, you're good. Need a quick check? WhatsApp 0314 4000131 (ask for Sayam) and we'll confirm with a photo in seconds.
What you get — and the build quality
- 1× Dell 240W genuine adapter brick (bench-tested, output verified)
- 1× Pakistan/UK 3-pin C5 wall cord (approximately 1.5m)
- 1× soft travel pouch
- 30-day check warranty card
The brick itself uses the same tooling as the original factory unit — same internal shielding, same strain-relief at the barrel end, same weight and feel. This isn't a cheap compatible; it's the real Dell part pulled from working laptops, fully tested by our team at Hafeez Center, Gulberg III, Lahore. Walk into our shop (Shop 66A, 3rd Floor) and we'll test it on your laptop before you buy.
Real-world use and charging speed
Under a full CPU+GPU load (like rendering or gaming), the charger keeps your battery at a steady charge while powering the system — no drain, no throttling. If you plug in while the laptop is off, you'll see the LED turn white immediately; after about 2 hours the battery hits 100%. Our 30-day check warranty covers any failure in that period — bring it back to the shop or contact us via WhatsApp, and we'll replace or refund it with no hassle.
Price in Pakistan 2026 — why Rs. 12,699 is the right price
We've priced this Dell 240W Big Barrel Charger at Rs. 12,699 because it's a genuine tested unit with a solid warranty. Cheaper clones exist, but they often sag under load or develop ripple that can stress your laptop's motherboard. For the same money you'd spend on a questionable compatible, you get a genuine Dell adapter that will last years. And if you ever need a different wattage — a 265W or 285W version also works with the same barrel — just ask Sayam on WhatsApp.
