Steady replacement charging for students and office workers whose original brick has failed or gone missing.
Condition: New
Note: price and availability are subject to change without prior notice
The Lenovo 65W 4.0mm Laptop Adaptor is in stock at Mascom International, priced at KSh 1,600, delivering 20V at 3.25A through a 4.0x1.7mm small round pin. This replacement adaptor for Lenovo laptops is brand new and sealed, and it suits IdeaPad and Yoga models that charge through the thin round plug rather than the rectangular slim tip or USB-C. The Lenovo 65W 4.0mm Laptop Adaptor uses a two-piece design: a compact brick with an attached DC cable, plus a detachable mains cord. You can collect it from our shop on the first floor of the Old Mutual Building, Kimathi Street, in Nairobi CBD.
Built for university students, accountants, NGO field staff and anyone whose charger has frayed, gone missing or stopped working, the Lenovo 65W 4.0mm Laptop Adaptor gets a stalled IdeaPad back to work the same day. A dead charger usually strikes at the worst moment, during exam week at Kenyatta University or the night before a client report is due. Instead of waiting weeks for a part, you can match the pin, check the voltage and walk out charging. Because it supplies 65W, it also covers small round pin Lenovo laptops that originally shipped with a lower-wattage 20V brick.
Where most Nairobi electronics shops sell unlabelled chargers from a bin, Mascom International checks the voltage, current and pin size against your laptop before you pay. Send your laptop model or a photo of the old adaptor label on WhatsApp and we confirm the fit first. Customers across Nairobi tell us the Lenovo 65W 4.0mm Laptop Adaptor saved them a costly trip to a service centre. Visit the shop to test it on your own machine, or order for pay-on-arrival delivery to any county. The Lenovo 65W 4.0mm Laptop Adaptor arrives the same day within Nairobi and its environs.
Common Questions About the Lenovo 65W 4.0mm Laptop Adaptor
How much is the Lenovo 65W 4.0mm Laptop Adaptor in Kenya?
The Lenovo 65W 4.0mm Laptop Adaptor costs KSh 1,600 brand new at Mascom International in Nairobi CBD. That price covers the two-piece adaptor with its attached DC cable, the detachable mains cord and a 6-month warranty against manufacturing defects. You pay on arrival anywhere in Kenya, so no money changes hands until the adaptor is in your hand. If your Lenovo charges over USB-C instead, the Lenovo 65W USB-C Laptop Adaptor costs KSh 2,300, which is KSh 700 more.
Which Lenovo laptops does the Lenovo 65W 4.0mm Laptop Adaptor fit?
The Lenovo 65W 4.0mm Laptop Adaptor fits Lenovo IdeaPad and Yoga laptops that take a 20V supply through a 4.0x1.7mm small round pin. Many budget and midrange IdeaPads from the last decade use this plug, and so do some Yoga convertibles. Lenovo changed connectors often, so the pin alone is not proof of fit. Check the label under your laptop or on the old brick for 20V, then send that photo or your model number on WhatsApp and we confirm before dispatch.
Can I use the Lenovo 65W 4.0mm Laptop Adaptor on a laptop that came with a 45W charger?
Yes, provided the old charger was also 20V with the same 4.0x1.7mm small round pin. A laptop draws only the current it needs, so a 65W adaptor simply has headroom to spare. The voltage is what must match exactly. Never use a charger with a different voltage, even when the plug slides in. If your old label shows anything other than 20V, ask us on WhatsApp which adaptor suits your laptop instead, and we will point you to the right one.
How does the Lenovo 65W 4.0mm Laptop Adaptor compare with the Lenovo 65W 5.5mm Laptop Adaptor?
Both carry the same 65W rating, but they use different plugs and are not interchangeable. The Lenovo 65W 4.0mm Laptop Adaptor, at KSh 1,600, has the thin 4.0x1.7mm small round pin found on many IdeaPad and Yoga models. The Lenovo 65W 5.5mm Laptop Adaptor, at KSh 1,800, has a wider 5.5mm barrel used on older Lenovo laptops. No ruler is needed: compare your old plug with ours in the shop, or send a photo on WhatsApp and we tell you which one fits.
Will the Lenovo 65W 4.0mm Laptop Adaptor survive KPLC power cuts and surges?
The Lenovo 65W 4.0mm Laptop Adaptor accepts a wide mains input range, but no adaptor is immune to the voltage spikes that often follow a KPLC power cut. Plug it into a surge protector or a UPS, especially in estates where the lights flicker during rainy evenings. When power returns after an outage, wait a few seconds before reconnecting. If you work from home in Kitengela or Ruaka where blackouts run long, keep the laptop battery healthy so it bridges the gap.
Who should buy the Lenovo 65W 4.0mm Laptop Adaptor, and who should skip it?
Buy the Lenovo 65W 4.0mm Laptop Adaptor if your Lenovo takes 20V through a 4.0x1.7mm small round pin and your charger has died, frayed or gone missing. It also makes sense as a second charger kept at the office while the first stays at home. Skip it if your laptop has a rectangular slim tip or a USB-C charging port; the Lenovo 65W USB-C Laptop Adaptor suits USB-C models. Owners of Legion gaming laptops that need far more power should skip it too.
Is the Lenovo 65W 4.0mm Laptop Adaptor easy to carry on a daily matatu commute?
Yes, the compact brick and detachable mains cord pack easily into a laptop bag for daily matatu or boda boda rides. The weak point on any adaptor is where the DC cable meets the brick and the plug, so wrap the cable loosely rather than knotting it tightly around the body. Keep it in a separate pocket away from water bottles, since the rainy season catches many commuters. Dust from roadside stages can coat the pin, so wipe it occasionally with a dry cloth.
How do I know the Lenovo 65W 4.0mm Laptop Adaptor is charging my laptop properly?
Your Lenovo shows a charging icon on the battery indicator within seconds of plugging in, and most IdeaPads also light a small charge LED beside the port. If the battery reads plugged in but not charging, Lenovo Vantage may have conservation mode switched on, which holds the battery below full to slow wear. Turn it off in Vantage when you need a full charge. A warm brick during charging is normal; a hot, smelling or buzzing one is not, so bring it back.
Technical Specifications
Core Function and Power Output
- 20V output at 3.25A — the steady voltage and current that small round pin Lenovo laptops expect for normal charging.
- 65W rated power — enough to run the laptop and recharge its battery at the same time through a working day.
- Wattage explained — volts multiplied by amps, so 20V times 3.25A gives the 65W figure printed in the name.
- Fixed 20V supply — a single voltage, so it cannot feed a different level into your laptop's charging circuit.
- Headroom over 45W bricks — laptops shipped with a lower-wattage 20V charger draw only the current they actually need.
- Wide mains input — works from ordinary wall sockets through the detachable cord, at home, in the office or a hostel.
- Charges while you work — no need to shut down; the laptop runs on mains power and tops up its battery together.
Compatibility and Connector
- 4.0x1.7mm round pin — the outer barrel is 4.0mm wide and the inner hole 1.7mm, matching Lenovo's small round socket.
- IdeaPad laptops — many budget and midrange IdeaPad models use this connector at 20V; confirm yours on WhatsApp first.
- Yoga convertibles — selected Yoga models with the small round port share the same pin and voltage requirement.
- Not for slim tip — Lenovo's rectangular slim tip connector needs a different adaptor, even at the same wattage.
- Not for USB-C — laptops that charge only through a USB-C port need the Lenovo 65W USB-C Laptop Adaptor instead.
- Label check — the sticker under your laptop or on the old brick lists the voltage, and it must read 20V.
- Fit confirmation — send your model number or a photo of the old adaptor on WhatsApp and Mascom International confirms before dispatch.
Build and Safety
- Two-piece brick design — the adaptor body stays on the floor or desk while the mains cord reaches the wall socket.
- Detachable mains cord — a damaged cord can be swapped on its own without replacing the whole adaptor.
- Attached DC cable — the laptop lead is fixed to the brick, so there is no loose joint near the laptop end.
- Compact body — slips into a laptop bag side pocket without adding noticeable bulk on a daily commute.
- Fanless operation — no moving parts, so the brick runs silently; gentle warmth while charging is expected.
- Cable care — loose coils protect the brick and plug ends of the cable, where wear normally starts first.
- Brand new stock — every unit is sealed and unused, never a pulled or second-hand charger.
Inclusions and Ownership
- Adaptor with attached DC cable — ready to plug into the laptop's small round charging port straight from the packaging.
- Detachable mains power cord — connects the brick to the wall; the plug type is confirmed on WhatsApp before dispatch.
- 6-month warranty — covers manufacturing defects under normal use, with claims handled at the Mascom International service desk.
- KSh 1,600 price — works out to under KSh 9 a day across the six-month warranty period.
- Pay-on-arrival delivery — inspect the adaptor and test it on your laptop before handing over any money.
- Spare charger option — keep one at the office and one at home so the cable never travels at all.
- In-store testing — bring your laptop to the shop and confirm the fit and charging light before paying.
