ASUS 33W 4.0mm Laptop Adaptor | 19V 1.75A Output | 4.0x1.35mm Connector | Replacement Charger
Steady mains power for compact VivoBook and E-series notebooks, ready for pay-on-arrival delivery across Kenya.
Condition: New
Note: price and availability are subject to change without prior notice
The ASUS 33W 4.0mm Laptop Adaptor delivers 19V at 1.75A through a 4.0x1.35mm barrel plug, and it is available at Mascom International for KSh 1,800, in stock now. This brand new replacement adaptor for ASUS laptops suits the small VivoBook, E-series and Transformer-type models that ASUS rates at 33W. The ASUS 33W 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 at Old Mutual Building, First Floor Room 4, Kimathi Street, in the Nairobi CBD, or order it for delivery.
Built for students, teachers, sales teams and home users across Kenya, the ASUS 33W 4.0mm Laptop Adaptor revives the thin, light ASUS laptops many people bought for school and office work. Original chargers fail in familiar ways: a cable that frays at the plug after months in a backpack, a brick that dies after a surge, or a charger left behind at a hostel. A dead charger turns a working laptop into a paperweight. This adaptor matches the voltage, current and connector your laptop expects, so a University of Nairobi student can finish assignments and a field officer in Nakuru can keep filing reports.
Unlike other electronics retailers in Kenya that sell one generic adaptor with a bag of loose tips, Mascom International stocks a dedicated ASUS 33W 4.0mm Laptop Adaptor with the correct plug fixed to the cable. Loose tips can wobble and lose contact; a fixed plug avoids that problem. Customers across Nairobi tell us their biggest worry is buying the wrong charger, so we check fit before you pay. Send your laptop model or a photo of your old adaptor's label on WhatsApp, and we will confirm the match. Walk in to test the ASUS 33W 4.0mm Laptop Adaptor on your own laptop, or order with pay-on-arrival delivery.
Common Questions About the ASUS 33W 4.0mm Laptop Adaptor
How much is the ASUS 33W 4.0mm Laptop Adaptor in Kenya?
The ASUS 33W 4.0mm Laptop Adaptor costs KSh 1,800 brand new at Mascom International on Kimathi Street, Nairobi CBD. That price covers the adaptor brick with its attached DC cable, a detachable mains cord and a 6-month warranty. Delivery is pay-on-arrival, so you pay in cash or by M-Pesa when it reaches you. For comparison, the ASUS 45W 4.0mm Laptop Adaptor costs KSh 2,000, which is KSh 200 more, and the ASUS 40W 2.5mm Laptop Adaptor costs KSh 1,600 but uses a much thinner pin.
Which ASUS laptops does the ASUS 33W 4.0mm Laptop Adaptor fit?
The ASUS 33W 4.0mm Laptop Adaptor fits ASUS laptops that ask for 19V at 1.75A through a 4.0x1.35mm round plug. In practice, that means small VivoBook models, compact E-series laptops and Transformer-type convertibles that ASUS rated at 33W. Many of these are 11.6-inch and 14-inch machines bought for school and light office work. ASUS used several plug sizes over the years, so a model name alone can mislead. Send your exact laptop model or a photo of your old adaptor's label on WhatsApp, and Mascom International will confirm the fit.
What do the numbers on the ASUS 33W 4.0mm Laptop Adaptor mean?
The ASUS 33W 4.0mm Laptop Adaptor outputs 19 volts at up to 1.75 amps, which multiplies to about 33 watts. Voltage must match your laptop exactly, and 19V is the standard for these ASUS models. The current figure is the most the adaptor can supply; your laptop draws only what it needs. The 4.0x1.35mm figure describes the plug: 4.0mm across the outside, with a 1.35mm hole in the centre. Check that your old label reads 19V and at least 1.75A, and that the plug matches.
Should I choose the ASUS 33W 4.0mm Laptop Adaptor or the ASUS 45W 4.0mm Laptop Adaptor?
Choose the ASUS 33W 4.0mm Laptop Adaptor at KSh 1,800 when your laptop's label calls for 33W, or 19V 1.75A. The ASUS 45W 4.0mm Laptop Adaptor costs KSh 2,000 and supplies more current through the same plug size. A laptop rated 45W needs that extra current; on a 33W adaptor its battery may stop charging during work, and the brick can run hot. A higher-rated adaptor at the same voltage can usually run a 33W laptop, because the laptop takes only what it needs. Match the label first, then save the KSh 200.
Will the ASUS 33W 4.0mm Laptop Adaptor cope with KPLC power cuts and surges?
The ASUS 33W 4.0mm Laptop Adaptor handles ordinary KPLC power cuts without trouble, because the laptop simply switches to its battery. The real risk is the surge when power returns, which can damage any adaptor's electronics. Plug the mains cord into a surge protector or a UPS rather than straight into the wall, especially where outages are frequent. Unplug the adaptor during thunderstorms in the long rains. A basic surge strip costs far less than a new charger, and it protects your laptop at the same time.
Can I use my laptop while the ASUS 33W 4.0mm Laptop Adaptor charges it?
Yes, the ASUS 33W 4.0mm Laptop Adaptor powers the laptop and charges its battery at the same time, just as the original charger did. Light tasks such as typing, browsing, online forms and video calls sit well within its 33W rating. Charging slows during heavier work, because the laptop uses more of the power itself. The brick warms up during use, which is normal. Keep it on a hard surface, not under a pillow or blanket, so heat can escape. If it becomes too hot to hold, unplug it and contact Mascom International.
Who should buy the ASUS 33W 4.0mm Laptop Adaptor, and who should skip it?
Buy the ASUS 33W 4.0mm Laptop Adaptor if your ASUS laptop's label reads 19V 1.75A and its plug is the 4.0x1.35mm size. It suits students, teachers and home users replacing a lost or broken charger at a fair price. Skip it if your label asks for 45W or more, or if your plug is thinner. Those laptops need the ASUS 45W 4.0mm Laptop Adaptor, the ASUS 65W 4.0mm Laptop Adaptor or the ASUS 40W 2.5mm Laptop Adaptor, all stocked at Mascom International. An ASUS that charges through USB-C needs a USB-C charger instead.
How do I make the ASUS 33W 4.0mm Laptop Adaptor last longer?
The ASUS 33W 4.0mm Laptop Adaptor lasts longest when its cable never bends sharply at either end. Most chargers fail where the cable meets the plug or the brick, after months of tight wrapping. Coil the cable loosely, and never wind it around the brick. On matatu and boda boda commutes, keep it in a padded pocket of your bag, away from heavy books and water bottles. Pull the plug out by its head, not by the cable. Wipe dust off the plug now and then so contact stays clean.
Technical Specifications
Core Function
- 19V DC output — the fixed voltage these ASUS laptops expect, so the charging circuit receives the supply it was designed around.
- Up to 1.75A current — enough to run the laptop and charge its battery together during typing, browsing, spreadsheets and video calls.
- 33W rated power — 19 volts multiplied by 1.75 amps, matching the rating printed on compatible ASUS laptops and their original chargers.
- Mains to DC conversion — the brick turns alternating current from the wall into the steady low-voltage direct current a laptop battery needs.
- Charges while in use — the laptop runs on mains and tops up its battery at once, so long work sessions do not drain it.
- Standard wall connection — the detachable mains cord plugs into an ordinary socket at home, in the office or in a lecture hall.
Compatibility
- Small ASUS VivoBook models rated 33W — the thin, light 11.6-inch and 14-inch laptops many buyers chose for school and office work.
- Compact ASUS E-series laptops — budget models sharing the 19V 1.75A rating and round 4.0mm plug; confirm your exact model on WhatsApp first.
- Transformer-type convertibles rated 33W — ASUS tablets with detachable keyboards that charge through this barrel plug rather than USB-C.
- Label check — your old adaptor or the laptop's base should read 19V with 1.75A or 33W; a 45W label needs the 45W sibling.
- Not for USB-C ASUS laptops — models with an oval USB-C charging port need a USB-C charger, not this round barrel plug.
- Not for thin-pin netbooks — older Eee PC netbooks use a far thinner 2.5mm pin, which the ASUS 40W 2.5mm Laptop Adaptor covers.
Build
- 4.0x1.35mm barrel plug — 4.0mm outside diameter with a 1.35mm centre hole, the round connector these ASUS models carry on the side.
- Fixed DC cable — the plug is permanently attached, so there are no loose tips to lose in a bag or wobble out of contact.
- Two-piece design — the brick sits between the DC cable and a detachable mains cord, so a damaged mains cord can be swapped alone.
- Compact brick — small enough for a laptop sleeve or backpack pocket, which suits students and staff moving between classes and offices.
- Replacement adaptor for ASUS laptops — brand new stock made to the same voltage, current and plug size as the original charger.
- Mains plug — Kenya uses 3-pin UK-style sockets, so confirm the plug type supplied on WhatsApp before your order is dispatched.
Inclusions
- Adaptor brick with attached DC cable — the main charger, with the 4.0x1.35mm plug fixed to the far end of the cable.
- Detachable mains power cord — connects the brick to the wall socket and unplugs for easier packing in a laptop bag.
- 6-month warranty — covers manufacturing defects under normal use, with claims handled at the Mascom International service desk in Nairobi CBD.
- Fit check before purchase — send a laptop model or label photo on WhatsApp, and the team confirms the match before you pay.
- Pay-on-arrival delivery — pay in cash or by mobile money on arrival, with same-day delivery within Nairobi and its environs.
- Counter test — plug the adaptor into your own laptop at our Kimathi Street shop and watch the charging light come on before paying.
- Unused stock — each adaptor is brand new, so you avoid the frayed cables and unknown history of second-hand chargers sold on the street.
Package Contents
The ASUS 33W 4.0mm Laptop Adaptor comes as a two-piece set: the adaptor brick with its DC cable and 4.0x1.35mm plug attached, plus a detachable mains power cord. That is everything needed to power and charge a compatible ASUS laptop from a wall socket. No loose tips or extra cables are included, because the plug is already the correct size. Kenya uses 3-pin UK-style sockets, so ask us on WhatsApp to confirm the mains plug type before dispatch.

If the adaptor stops working within that period, bring it to our service desk at Old Mutual Building, Kimathi Street, Nairobi CBD, where our team will assess it and handle your claim.
