Acer 90W Big Pin Laptop Adaptor is in stock at Mascom International, priced at KSh 1,800, and supplies 19V at 4.74A through a wide 6.3x3.0mm barrel connector. It is a brand new and sealed replacement adaptor for Acer laptops, mainly the older Aspire and TravelMate generations built around the thicker big pin port. Pick up the Acer 90W Big Pin Laptop Adaptor at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, or have it delivered with payment on arrival. Mascom International backs every unit with a 6-month warranty, so a cheap fix for an ageing laptop still comes with proper cover.
Designed for accountants, small business owners, teachers and university students who still rely on an older Acer, the Acer 90W Big Pin Laptop Adaptor answers a familiar question: is the laptop dead, or only the charger? In most cases we see, the computer is fine and the brick or its cable has given up. Thin cables fray at the plug, and cheap bricks bought from street hawkers often fail after the first KPLC surge. A correctly rated 19V 4.74A unit puts the machine back to work for M-Pesa records, KRA iTax filing and school assignments. The Acer 90W Big Pin Laptop Adaptor costs far less than a new laptop.
Unlike other electronics retailers in Kenya that guess the connector by eye, Mascom International matches the voltage, current and barrel size to your laptop label before the sale. Buyers throughout Kenya report that this simple step ended months of loose, unreliable charging from mismatched bricks. Bring your laptop to our Kimathi Street counter and test the Acer 90W Big Pin Laptop Adaptor on it before paying, or send the old label photo on WhatsApp and order for pay-on-arrival delivery to any of the 47 counties.
Common Questions About the Acer 90W Big Pin Laptop Adaptor
How much is the Acer 90W Big Pin Laptop Adaptor in Kenya?
The Acer 90W Big Pin Laptop Adaptor sells for KSh 1,800 at Mascom International in Nairobi CBD, brand new. You get the adaptor with its attached laptop cable, a detachable mains cord and a 6-month warranty for that price. Delivery is pay-on-arrival in every county, so you check the plug before paying. It costs KSh 1,450 less than the Acer 135W 7.4mm Laptop Adaptor at KSh 3,250, which serves gaming laptops with a different connector.
Which laptops work with the Acer 90W Big Pin Laptop Adaptor?
The Acer 90W Big Pin Laptop Adaptor works with Acer laptops whose original adaptor reads 19V 4.74A and whose charging port takes a 6.3x3.0mm barrel. That wide connector appears mostly on older Acer Aspire and TravelMate generations rather than current slim models. Many Acer laptops use a narrower plug, so the model family alone is not enough. Message Mascom International on WhatsApp at +254 708 852 521 with your laptop model or old label and we confirm fit before dispatch.
Is the Acer 90W Big Pin Laptop Adaptor the same as the Dell 90W 7.4mm Laptop Adaptor?
No, the Acer 90W Big Pin Laptop Adaptor and the Dell 90W 7.4mm Laptop Adaptor share a 90W rating and a KSh 1,800 price at Mascom International, but their plugs differ. The Acer unit uses a 6.3x3.0mm barrel, while the Dell unit uses a 7.4mm plug made for Dell laptops. Neither fits the other brand's port. Pick by your laptop's maker and label. Acer gaming laptops needing 135W should look at the Acer 135W 7.4mm Laptop Adaptor instead.
Can I use a 65W charger instead of the Acer 90W Big Pin Laptop Adaptor?
It is a poor idea, even when a lower-rated plug fits the port. A laptop built for the Acer 90W Big Pin Laptop Adaptor expects 4.74A at 19V, and a weaker charger may charge slowly, stop charging under load, or run hot. Going the other way is safe: a correctly sized adaptor with more current than needed causes no harm. For daily office use in Kenya, match the 19V 4.74A rating on your original label.
How do I protect the Acer 90W Big Pin Laptop Adaptor from dust and heat in Kenya?
Keep the Acer 90W Big Pin Laptop Adaptor off dusty floors and away from direct sun, especially in shops around Industrial Area or River Road where grit settles quickly. Dust inside the barrel causes loose, on-off charging, so blow it out gently now and then. In hot, humid towns such as Mombasa, store the brick in a dry bag overnight. Always run it through a surge protector, because KPLC voltage spikes harm adaptors more than heat does.
How can I tell whether my old Acer adaptor or the laptop itself is faulty?
The quickest test is plugging a known working Acer 90W Big Pin Laptop Adaptor into your laptop and watching the charging light. If it charges, the old brick or its cable has failed and the laptop is fine. Other signs of a dying adaptor are a frayed cable near the plug, charging that cuts out when the cord moves, or a brick that stays cold. Bring the laptop to Mascom International on Kimathi Street and we test it on the spot.
Who should buy the Acer 90W Big Pin Laptop Adaptor and who should skip it?
Buy the Acer 90W Big Pin Laptop Adaptor if your Acer label reads 19V 4.74A and the port takes the wide 6.3x3.0mm barrel, especially if the laptop still runs well apart from charging. Skip it for modern slim Acer models with a narrower pin, USB-C charging Acer laptops, and Acer gaming machines. The gaming machines that call for 19V 7.1A with a 7.4x5.0mm pin belong with the Acer 135W 7.4mm Laptop Adaptor, also in stock.
Is it worth replacing the adaptor on an older Acer laptop?
Yes, if the laptop still boots and the screen, keyboard and storage work, a KSh 1,800 Acer 90W Big Pin Laptop Adaptor is far cheaper than a replacement laptop. Many older Acer notebooks still handle email, Microsoft Office, eCitizen forms and online classes without trouble. Check the battery too: if it no longer holds charge, the laptop can still run from the adaptor while plugged in at a desk in Kilimani, Thika or anywhere with mains power.
Technical Specifications
Core Function and Power Output
- 19V at 4.74A output — about 90W of steady power, the standard rating for many mid-range Acer notebooks of earlier generations.
- 90W capacity — runs the laptop under normal office loads and charges the battery at the same time without strain.
- Single fixed voltage — 19V only, so the laptop receives exactly what its charging circuit was designed for, with nothing to set.
- Charges whether the laptop is switched on, asleep or fully off, so overnight top-ups and working sessions both suit it.
- Replacement adaptor for Acer laptops — restores charging after the original unit is lost, frayed, burnt by a surge or simply worn out.
- Two-piece design — the brick sits beside the laptop while a separate mains cord reaches the wall or an extension board.
Compatibility and Connector Fit
- 6.3x3.0mm big pin barrel — 6.3mm across the outside with a 3.0mm opening in the centre; the port must match this size.
- Fits Acer laptops labelled 19V 4.74A with the wide barrel port, found mostly on older Aspire and TravelMate generations.
- Not interchangeable with the narrower plugs on most current Acer models, so check the port size before ordering.
- Lower-power 19V Acer laptops with the same 6.3x3.0mm port can also use it, drawing only the current they need.
- Not for USB-C Acer laptops or the 7.4x5.0mm gaming connector — those owners need a different unit from our shelves.
- Fit checked on WhatsApp — share your laptop model or a photo of the old adaptor sticker, and our staff confirm the match.
Build and Everyday Safety
- Closed brick housing — protects the electronics inside from bumps in a laptop bag and from light dust on a busy desk.
- Fixed laptop cable — the DC lead is built into the brick, so the part that plugs into your laptop cannot go missing.
- Removable mains cord — if the wall cord gets damaged, replace only that piece rather than buying a full adaptor again.
- Brand new unit — no prior owner, no repaired cable ends, and no hidden wear inside the housing from earlier use.
- Warms up during long charging sessions — this is normal; leave the brick in open air rather than under cushions or blankets.
- Use behind a surge protector — reduces the risk of damage from voltage spikes when electricity returns after a blackout.
Inclusions and After-Sales Support
- Adaptor with attached DC cable — the charging brick with its 6.3x3.0mm plug, ready to use as soon as it is unboxed.
- Detachable mains power cord — connects the brick to the wall socket to complete the two-piece set.
- Plug type checked before dispatch — confirm on WhatsApp which mains plug end comes with your unit before we send it.
- 6-month warranty — covers manufacturing defects under normal use, with claims taken at our Nairobi CBD service desk.
- Pay-on-arrival delivery — receive the adaptor, check the connector against your port and test it before you pay anything.
- Counter testing in store — bring the laptop to Kimathi Street and confirm it charges properly before you walk out.
