Why these specs matter
The 20V / 4.5A output ensures your laptop charges at its designed rate – too low a current and the battery won't charge during use; too high and you risk overheating. The Lenovo Square Tip is keyed to prevent wrong insertion, and the 100-240V input means it works on any wall outlet in Pakistan without a converter.
Compatibility — which laptops does this fit?
This 90W Lenovo charger is the OEM-spec power adapter for:
Wattage and connector are the two factors that decide compatibility. The Lenovo Square Tip 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.
Compatible models beyond the list
Some early IdeaPad Z-series and G40 models also use the same square tip, but we recommend checking the voltage and current on your original adapter. A quick photo to WhatsApp 0314 4000131 and we'll verify in minutes.
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 Lenovo unit is exactly what came with the laptop new — same chassis injection, same internal magnetic shielding, same cable strain-relief.
What you get
- 1× Lenovo 90W adapter brick
- 1× Pakistan/UK 3-pin AC cord
- 30-day check warranty card
Original vs. compatible – the real difference
A genuine Lenovo charger uses certified components that filter AC ripple and handle load spikes without overheating. Cheaper generic chargers often skip safety capacitors, leading to unstable voltage that can damage your motherboard over time. This unit is bench-tested for output stability, ripple, and short-circuit protection – something most clone chargers fail.
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 Lenovo 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.
Tips for best performance
- Keep the charger on a hard, flat surface for airflow – avoid blankets or carpets.
- Unplug the AC cord if storing for weeks – the standby circuit draws a tiny current.
- If the LED flickers, check the wall socket or cable – not the brick.
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 Lenovo 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. Lenovo Square Tip is the only fit — don't force a wrong-size pin.
3. Voltage
Must be 20V. Never use a Lenovo 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 Lenovo 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.
Will this 90W charger work with my IdeaPad G50?
Yes. This adapter outputs 20V at 4.5A which exactly matches the IdeaPad G50 (and all other listed models). The Lenovo Square Tip connector is the OEM specification — no adapter or convertor required. Plug it in and you're charging at full speed.
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 Lenovo 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.
Can I use a 90W charger on a 65W laptop?
Yes, it's safe. The laptop only draws the power it needs. The 90W brick runs cooler than a 65W under load, so it's actually better for longevity.
How do I know if my charger is failing?
Signs: slow charging, battery draining while plugged in, intermittent power, or the brick making a buzzing sound. If you notice any, stop using it and test with ours at the shop or on WhatsApp.
