Compatibility — which laptops does this fit?
This 90W 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 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 90W 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.
How long does a Dell 90W charger last? In our experience, these OEM adapters easily last 5-7 years with normal use. The cable strain relief is robust, and the brick's internal components are rated for continuous operation. We've seen many units outlast the laptops they came. If you're replacing a failed charger, this genuine unit will give you another half-decade of reliable service.
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 90W, 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 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
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.
Will this 90W charger work with my Latitude E6420?
Yes. This adapter outputs 19.5V at 4.62A which exactly matches the Latitude E6420 (and all other listed models). The 7.4mm × 5.0mm barrel connector is the OEM specification — no adapter or convertor required. Plug it in and you're charging at full speed.
How can I be sure this charger is genuine?
We source our stock from decommissioned office laptops and sealed surplus. Each charger is visually inspected for Dell branding, part numbers, and holographic labels. Then it goes through a bench test using a dummy load to verify output voltage and current. Only units that match Dell's spec sheet are sold. If you have doubts, visit our shop in Hafeez Center and we'll test it in front of you.
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.
