Mascom International stocks the HP 45W Blue Pin Laptop Adaptor at KSh 1,900, brand new and sealed. This replacement adaptor for HP laptops supplies 19.5V at 2.31A, which works out to 45W, through the 4.5x3.0mm blue-tipped pin HP uses on its thinner notebooks. The HP 45W Blue Pin Laptop Adaptor suits machines whose label lists that lower rating, including many HP Stream laptops, Pavilion x360 convertibles and lighter 14-inch models. You can collect one from our store at Old Mutual Building, Kimathi Street, Nairobi CBD, or have it delivered and pay when it reaches you.
Built for university students, journalists, teachers and anyone working on a thin HP notebook across Kenya, the HP 45W Blue Pin Laptop Adaptor restores power when the first charger goes missing between lecture halls or breaks after months in a backpack. A student at JKUAT or the University of Nairobi cannot submit coursework from a dead laptop. Low-power notebooks have no need for a 65W brick, and the HP 45W Blue Pin Laptop Adaptor gives them exactly the rating printed on their sticker, for KSh 100 less than our 65W replacement.
Where most Nairobi electronics shops hand over any blue-pin charger without asking about your laptop's rating, Mascom International checks the label first, so a 45W unit only goes to a 45W machine. Customers across Nairobi tell us that quick check saves them a second trip to town. Bring your old adaptor along too, and we match its label line by line. If your laptop reads 19.5V 3.33A, the 65W version is the one to buy. Send your model on WhatsApp or walk in with the laptop, and we confirm the HP 45W Blue Pin Laptop Adaptor fits before you pay a shilling.
Common Questions About the HP 45W Blue Pin Laptop Adaptor
How much is the HP 45W Blue Pin Laptop Adaptor in Kenya?
The HP 45W Blue Pin Laptop Adaptor is priced at KSh 1,900 brand new at Mascom International in Nairobi CBD. That includes the adaptor with its attached blue-pin cable, a detachable mains cord and a 6-month warranty, with pay-on-arrival delivery anywhere in Kenya. The HP 65W Blue Pin Laptop Adaptor costs KSh 2,000, only KSh 100 more, while the original HP 65W Blue Pin Original Laptop Adaptor sells for KSh 3,500.
Which HP laptops take the HP 45W Blue Pin Laptop Adaptor?
The HP 45W Blue Pin Laptop Adaptor fits HP laptops with a round 4.5x3.0mm blue-tip port and a rating of 19.5V 2.31A. Many HP Stream laptops, Pavilion x360 convertibles and lighter 14-inch HP notebooks with low-power processors carry that rating. Some ProBook and EliteBook models shipped with either a 45W or 65W charger, so read your label. Mascom International confirms fit if you WhatsApp your laptop model to +254 708 852 521.
What happens if I plug the HP 45W Blue Pin Laptop Adaptor into a 65W HP laptop?
A 65W HP laptop will accept the HP 45W Blue Pin Laptop Adaptor physically, but it may warn you and charge slowly. The plug shape is identical, yet the laptop asks for more power than 45W supplies. Under light use it may still charge; under heavy use the battery can drain while plugged in. If your laptop label reads 19.5V 3.33A, buy the 65W blue-pin adaptor instead for KSh 100 more.
Why choose the HP 45W Blue Pin Laptop Adaptor over the 65W version that costs KSh 100 more?
Choose the HP 45W Blue Pin Laptop Adaptor only if every laptop you will charge is rated 19.5V 2.31A. It matches that label exactly and saves KSh 100, at KSh 1,900 against KSh 2,000. The HP 65W Blue Pin Laptop Adaptor runs both 45W and 65W blue-pin laptops, so it suits households with mixed machines better. If you are unsure of your rating, the 65W unit is the safer purchase.
How should I use the HP 45W Blue Pin Laptop Adaptor during KPLC outages and in coastal humidity?
Connect the HP 45W Blue Pin Laptop Adaptor through a surge protector, and unplug it when KPLC power drops. Surges when supply returns are a common reason chargers fail in Kenya. In Mombasa, Kilifi and Diani, humid air settles on metal contacts, so store the adaptor in a dry bag with the cable loosely coiled. Wipe the blue tip before plugging in if it has been sitting in a damp room.
Who is the HP 45W Blue Pin Laptop Adaptor made for, and who needs a bigger adaptor?
The HP 45W Blue Pin Laptop Adaptor is made for owners of thin, low-power HP notebooks labelled 19.5V 2.31A, such as students and teachers on HP Stream laptops. It is not for 65W blue-pin laptops, gaming laptops, or HP machines charging through USB-C or the older 7.4mm big pin. Owners of 65W laptops should buy the HP 65W Blue Pin Laptop Adaptor, and USB-C users need a USB-C adaptor instead.
Why does my HP laptop show an adaptor warning after I plug in the HP 45W Blue Pin Laptop Adaptor?
An adaptor warning with the HP 45W Blue Pin Laptop Adaptor usually means your laptop is rated higher than 45W. HP laptops read the adaptor's rating through the thin centre pin, and a 65W machine flags a 45W unit as underpowered. Dust in the barrel or a bent centre pin can cause the same message. Clean the tip, check the label, and bring the laptop to our Kimathi Street store if the warning stays.
How long will the HP 45W Blue Pin Laptop Adaptor last, and how can I make it last longer?
The HP 45W Blue Pin Laptop Adaptor lasts longest when the cable is not bent sharply and the brick stays cool. Most charger failures in Kenya come from frayed tips, tight cable wraps and power surges, not from the brick itself. Coil the cable loosely, pull by the connector rather than the wire, and charge through a surge protector. A 6-month warranty from Mascom International covers any manufacturing defect in the meantime.
Technical Specifications
Core Function and Power Output
- 19.5V output at 2.31A — 45W in total, the rating HP sets for many of its thinner, low-power notebooks.
- Sized for low-power processors — enough to run browsing, Word, Google Classroom and recorded lectures while the battery charges.
- 19.5V voltage — the same as every HP blue-pin adaptor, so only the current rating separates it from the 65W units.
- 100V to 240V AC input — runs from Kenya's 240V sockets and from the lower voltages used in many other countries.
- Charges with the laptop on, asleep or shut down — the battery generally fills quickest with the lid closed and the laptop resting.
- Limited to 45W — laptops whose label asks for 3.33A or more need the 65W blue-pin unit to charge properly.
Compatibility and Connector Fit
- 4.5x3.0mm blue tip with a centre pin — the same plug shape as the 65W blue-pin adaptors, so check the rating, not just the fit.
- Suits HP laptops labelled 19.5V 2.31A — many HP Stream, Pavilion x360 and lighter 14-inch HP notebooks carry this rating.
- Centre pin reports 45W to the laptop — a machine expecting more may show an adaptor warning and limit its charging.
- Physically fits 65W blue-pin laptops — but they draw more than 45W, so charging can stall or reverse under heavy load.
- Not for 7.4mm big-pin or USB-C HP laptops — those use different connectors and need their own adaptors from our counter.
- WhatsApp fit check — send your laptop model or a photo of the old charger's output line and we confirm before dispatch.
Build and Day-to-Day Care
- Replacement adaptor for HP laptops — made to the 19.5V 2.31A rating and blue-pin connector used on HP's 45W notebooks.
- Two-piece construction — the DC cable is fixed to the brick, and the mains cord plugs into the opposite end.
- Detachable mains cord — a damaged cord can be replaced separately, keeping the brick and its blue-pin cable in service.
- Black casing — a simple, low-key finish that sits quietly on a library desk or in the front pocket of a backpack.
- Keep the tip clean — dust inside the blue barrel can interrupt charging, so wipe it with a dry cloth now and then.
- Let it breathe — the brick warms during charging, so keep it on a hard, open surface instead of a mattress or cushion.
Inclusions and Buyer Support
- Adaptor brick with its attached DC cable ending in the 4.5x3.0mm blue-pin connector for 45W HP laptops.
- Detachable mains power cord — confirm the plug type with us on WhatsApp before dispatch so it suits your sockets.
- Brand new and sealed — test it on your own laptop at our Kimathi Street counter before you hand over any money.
- 6-month warranty through Mascom International — covers manufacturing defects, with claims handled at our Nairobi CBD service desk.
- Pay-on-arrival delivery to all 47 counties — useful for students at campuses far from Nairobi who cannot visit the store.
- Free fit advice — call or WhatsApp +254 708 852 521 with your laptop model and we tell you which blue-pin unit suits it.
Package Contents
The HP 45W Blue Pin Laptop Adaptor arrives as a two-piece set: the adaptor brick with its permanently attached DC cable and 4.5x3.0mm blue-pin connector, and a detachable mains power cord that runs from the brick to the wall. Because Kenyan sockets are the 3-pin UK style, we confirm the plug type on the cord with you on WhatsApp before dispatch. The box holds no pouch, battery or spare tips.
