Full specifications

Compatibility — which laptops does this fit?

This 45W Dell charger is the OEM-spec power adapter for:

Wattage and connector are the two factors that decide compatibility. The 4.5mm × 3.0mm slim tip 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 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 45W 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.

Why the Original Dell Charger Matters

Using a genuine Dell charger ensures your laptop receives clean, stable power without risking motherboard damage from voltage spikes. Third-party chargers often lack proper shielding and may cause erratic charging or battery degradation over time. This Dell 45W unit is bench-tested at our shop to confirm it meets OEM specifications — output ripple, thermal protection, and connector fit are all verified before shipping.

Who Needs This Charger?

Perfect for professionals and students using a Latitude 7290, 5290, or similar model who need a reliable replacement for a lost or damaged charger. Also ideal as a backup adapter to keep in your bag or at the office. Whether you're in Lahore, Karachi, Islamabad, Rawalpindi, Faisalabad, or Multan, we ship nationwide via TCS or Leopards with same-day delivery within Lahore.

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 45W, 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. 4.5mm × 3.0mm slim tip 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

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.

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. We also stock high-grade compatible versions if budget is tight — just tell us on WhatsApp 0314 4000131 which you prefer.

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.

Will this 45W charger work with my Latitude 7290?

Yes. This adapter outputs 19.5V at 2.31A which exactly matches the Latitude 7290 (and all other listed models). The 4.5mm × 3.0mm slim tip with center pin connector is the OEM specification — no adapter or convertor required. Plug it in and you're charging at full speed.
