Compatibility — which laptops does this fit?
This 45W Lenovo charger is the OEM-spec power adapter for:
Wattage and connector are the two factors that decide compatibility. The Lenovo Slim Tip (Yellow USB-style 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 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 45W 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 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.
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 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 Slim Tip (Yellow USB-style pin) 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.
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 higher-wattage charger instead?
Yes, higher wattage is safe as long as the voltage matches. A 70W or 90W Lenovo brick with the same Lenovo Slim Tip 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.
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.
