HP 65W 7.4mm Laptop Adaptor is in stock at Mascom International, priced at KSh 1,600, brand new and sealed, with an 18.5V output at 3.5A through the 7.4x5.0mm big pin. Those figures give roughly 65 watts, the standard rating for many older HP EliteBook, ProBook, Compaq and Pavilion laptops with the round big pin socket. The HP 65W 7.4mm Laptop Adaptor is a replacement adaptor for HP laptops, made as a two-piece brick with a fixed DC lead and a detachable mains cord. Collect it from Old Mutual Building, Kimathi Street, Nairobi CBD, or have it delivered and pay on arrival.
Built for university students, clerks, teachers, small business owners and families across Kenya who still rely on an older HP laptop, the HP 65W 7.4mm Laptop Adaptor brings a dead machine back to work for a modest outlay. A frayed cable or a brick that died in a KPLC surge often makes people think the whole laptop has failed. In many of those cases, a new adaptor is all it takes. With the HP 65W 7.4mm Laptop Adaptor connected, an old EliteBook or ProBook is back to handling M-Pesa statements, eCitizen forms, assignments and email.
Where most Nairobi electronics shops guess the fit from the plug alone, Mascom International matches the voltage, current and connector to your exact HP model. At Mascom International, we're seeing many buyers bring in old HP laptops they had written off, then leave with them charging again. Send your model number or a photo of the old adaptor's label on WhatsApp, and we confirm whether the HP 65W 7.4mm Laptop Adaptor is right before dispatch. Visit the Kimathi Street shop to test it on your laptop, or order for pay-on-arrival delivery anywhere in Kenya.
Common Questions About the HP 65W 7.4mm Laptop Adaptor
How much is the HP 65W 7.4mm Laptop Adaptor in Kenya?
The HP 65W 7.4mm Laptop Adaptor costs KSh 1,600, brand new, at Mascom International on Kimathi Street, Nairobi CBD. The price includes the brick with its attached DC lead, the detachable mains cord and a 6-month warranty, and you pay only when delivery reaches you. The HP 90W 7.4mm Laptop Adaptor sells at the same KSh 1,600, while the HP 65W Blue Pin Laptop Adaptor for newer HP models costs KSh 400 more.
Will the HP 65W 7.4mm Laptop Adaptor work on my older EliteBook or ProBook?
The HP 65W 7.4mm Laptop Adaptor works on older EliteBook, ProBook, Compaq and Pavilion laptops that have the round 7.4x5.0mm big pin socket and a 65W rating. Check the laptop's base or the old brick for 18.5V, 3.5A or 65W. Newer EliteBook and ProBook generations moved to the blue-tipped plug or USB-C, so the generation matters. Send your exact model on WhatsApp, and Mascom International confirms the fit before dispatch.
What is the difference between the HP 65W 7.4mm Laptop Adaptor and the HP 65W Blue Pin Laptop Adaptor?
The difference is the connector: the HP 65W 7.4mm Laptop Adaptor uses the older round big pin, while the HP 65W Blue Pin Laptop Adaptor uses the slimmer blue-tipped plug found on newer HP laptops. Both supply 65 watts, but neither plug fits the other's socket. The big pin version costs KSh 1,600 and the blue pin KSh 2,000. Look at your laptop's charging port: a wide round socket with a centre pin needs this one, while a slim socket needs the blue pin.
Does the HP 65W 7.4mm Laptop Adaptor handle Kenyan heat, dust and coastal humidity?
The HP 65W 7.4mm Laptop Adaptor works normally in Kenyan conditions when it gets basic care. In hot, dusty towns such as Garissa or Lodwar, keep the brick off the floor and blow dust out of the plug now and then. In humid places like Mombasa, Malindi or Kilifi, store it in a dry bag, because moisture can corrode the centre pin over time. Never handle it with wet hands, and keep it shaded rather than in direct sun on a windowsill.
Is it worth buying a new adaptor for an old HP laptop?
For many owners, the KSh 1,600 HP 65W 7.4mm Laptop Adaptor is a low-cost way to get a working laptop back. If the machine powers on with a borrowed charger, the laptop itself is fine and only the adaptor failed. Students at Kenyatta University and JKUAT often revive a sibling's old EliteBook this way for typing assignments and online classes. If the laptop stays dead even with a known-good adaptor, bring it to our shop so staff can check the charging socket first.
Who should buy the HP 65W 7.4mm Laptop Adaptor, and who should not?
Buy the HP 65W 7.4mm Laptop Adaptor if your HP laptop has the round big pin and a 65W label, which covers many older office and home models. Skip it if your laptop is rated 90W, because it may charge slowly or not at all under load; the HP 90W 7.4mm Laptop Adaptor costs the same KSh 1,600. Gaming notebooks rated 135W need the HP 135W 7.4mm Laptop Adaptor, and USB-C HP laptops need a USB-C charger instead.
Is the 18.5V HP 65W 7.4mm Laptop Adaptor safe on a laptop labelled 19V?
The 18.5V HP 65W 7.4mm Laptop Adaptor normally runs HP 65W big pin laptops labelled 19V, since HP sold many of these models with either voltage. The half-volt gap is small for these machines, and the wattage and connector matter more. Because a few models are stricter about the adaptor they accept, send your exact model number on WhatsApp first. Mascom International confirms the match before you buy, so you never pay for an adaptor your laptop rejects.
Can a student carry the HP 65W 7.4mm Laptop Adaptor every day?
Yes, the HP 65W 7.4mm Laptop Adaptor is smaller and lighter than the 90W and 135W HP big pin units, so it travels easily in a backpack. Students riding matatus to the University of Nairobi, Moi University or Strathmore can keep one in the laptop sleeve without much extra weight. Wrap the cables in loose loops held with a strap, and never yank the plug out by its cable. A side pocket away from water bottles also protects it in the rainy season.
Technical Specifications
Power Output and Purpose
- 18.5V at 3.5A output — the two values multiply to roughly 65 watts, the everyday rating of many older HP office and home laptops.
- 65W rating passed through the centre pin — the laptop identifies the adaptor and charges the battery while you type, browse and stream.
- AC to DC conversion — the brick turns 240V wall electricity into the low, steady voltage an HP laptop needs to run and charge.
- Handles normal office and study work — word processing, spreadsheets, web browsing, online classes and video calls all run while the battery fills.
- Lower output than the 90W and 135W units — right for 65W laptops, but too little for HP machines that ask for more.
- Fine for all-day charging — the laptop stops pulling charging current once the battery is full, so the adaptor can stay connected at your desk.
Compatibility and Connector
- 7.4x5.0mm big pin plug — a wide 7.4mm round barrel with a 5.0mm opening and a fine centre pin that tells the laptop its rating.
- Fits older HP big pin laptops rated 65W — including many EliteBook, ProBook, Compaq and Pavilion models from before HP moved to slimmer plugs.
- Works with 18.5V and many 19V HP big pin laptops — HP sold numerous models with either voltage on the same connector.
- Not for newer blue-tipped HP plugs — those laptops need the HP 65W Blue Pin Laptop Adaptor, which uses a slimmer connector.
- Not for Dell 7.4mm laptops — the Dell plug looks the same, but its identification signal differs, so charging can fail.
- Label check first — look for 18.5V, 3.5A or 65W under the laptop, or send its model number to +254 708 852 521.
Build and Handling
- Two-piece brick — the body carries the electronics, with the laptop lead fixed on one side and a socket for the mains cord.
- Detachable mains cord — the wall-side cord unplugs from the brick, so a damaged cord can be replaced on its own at low cost.
- Compact body — smaller and lighter than the 90W and 135W HP big pin bricks, which helps anyone carrying it daily.
- Normal warmth — the brick warms up while charging, so keep it on a hard, open surface, never under bedding or inside a closed bag.
- Plug and pin care — pull the plug out by its head, not the cable, and keep the centre pin straight to avoid charging faults.
- Surge protection — connect through a surge protector or UPS, especially where mains power returns with spikes after an outage.
Inclusions and Support
- Adaptor brick with an attached DC lead finished in the 7.4x5.0mm big pin plug for your HP laptop.
- Detachable mains power cord for connecting the brick to a wall socket, extension lead or UPS.
- Mains plug type confirmed with you on WhatsApp before the parcel leaves our shop.
- 6-month warranty from Mascom International covering manufacturing defects, handled at our Nairobi CBD service desk.
- Pay-on-arrival delivery to all 47 counties, with same-day delivery in Nairobi and its environs.
- Try before you pay — bring your HP laptop to Old Mutual Building and test the adaptor at the counter.
