A pocket-sized lifeline for tiny schoolwork companions that most town stalls stopped stocking years ago.
Condition: New

The HP 30W 4.0mm Laptop Adaptor, with a 19V 1.58A output and a 4.0x1.7mm pin, is in stock at Mascom International, priced at KSh 1,400 and brand new. Volts times amps gives 30 watts, the low-power rating HP Mini netbooks were designed around. This replacement adaptor for HP laptops is meant for those small machines rather than full-size notebooks, which need more power and a different plug. The HP 30W 4.0mm Laptop Adaptor sits on our shelf at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD. Orders placed within Nairobi go out for delivery the same day.
Designed for families, schoolchildren, NGO field staff and anyone keeping an HP Mini going for light work, the HP 30W 4.0mm Laptop Adaptor answers a question many owners have stopped asking: where can I still find a charger for this? Netbook chargers are small and easy to misplace, and once the original dies, many people assume the machine is finished. A matched adaptor brings it back for typing assignments, reading PDFs, checking email or filling in eCitizen forms. At 30W it is sized for the netbook, so it stays light enough to slip into a school bag beside exercise books.
Unlike other electronics retailers in Kenya, which mostly stock the common 65W and 90W chargers, Mascom International keeps the HP 30W 4.0mm Laptop Adaptor for the smaller HP machines many shops have dropped. Buyers throughout Kenya tell us netbook chargers are hard to track down, which is exactly why we hold this one. Before ordering, send your HP Mini model or a photo of the old adaptor label on WhatsApp, and we will confirm the pin and voltage. Then collect the HP 30W 4.0mm Laptop Adaptor from our CBD shop, or have it delivered and pay when it arrives.
Common Questions About the HP 30W 4.0mm Laptop Adaptor
How much is the HP 30W 4.0mm Laptop Adaptor in Kenya?
The HP 30W 4.0mm Laptop Adaptor sells for KSh 1,400, brand new, at Mascom International in Nairobi CBD. For that you get the adaptor with its attached DC cable, a detachable mains power cord and 6 months of warranty cover. Payment happens on arrival, wherever you are in Kenya. It costs KSh 200 less than the HP 65W Bullet Pin Laptop Adaptor at KSh 1,600, which serves larger, older HP laptops with a higher power draw and a wider plug.
Which HP Mini netbooks work with the HP 30W 4.0mm Laptop Adaptor?
The HP 30W 4.0mm Laptop Adaptor works with HP Mini netbooks that charge through a 4.0x1.7mm round socket and are rated at 19V. HP sold the Mini line in several series over a few years, and not every series used the same plug, so check before buying. Look at the label on your old charger for 19V, 1.58A and the plug size, or read the rating under the netbook. Send either on WhatsApp to +254 708 852 521, and Mascom International will confirm the match.
Should I get the HP 30W 4.0mm Laptop Adaptor or the HP 65W Bullet Pin Laptop Adaptor?
Get the HP 30W 4.0mm Laptop Adaptor only if your machine is an HP Mini netbook with a 4.0x1.7mm socket; get the HP 65W Bullet Pin Laptop Adaptor for older full-size Pavilion, Envy and TouchSmart laptops. The two are not interchangeable. The 30W unit supplies 19V at 1.58A, while the 65W unit supplies 19.5V at 3.33A through a wider 4.8x1.7mm plug. Prices are KSh 1,400 and KSh 1,600 respectively. Your socket size settles the choice long before price does.
Is the HP 30W 4.0mm Laptop Adaptor safe during KPLC outages and dusty weather?
The HP 30W 4.0mm Laptop Adaptor handles everyday use on Kenyan mains power, but electricity returning after a KPLC outage can arrive as a surge strong enough to damage any charger. A surge protector shields both the adaptor and the netbook behind it. In dusty towns and during the dry season, blow out the netbook's charging socket now and then and keep the plug in a pouch when it is not in use. A clean socket keeps the slim 4.0mm pin seated firmly.
Can I charge a full-size HP laptop with the HP 30W 4.0mm Laptop Adaptor?
No, the HP 30W 4.0mm Laptop Adaptor is meant for HP Mini netbooks, not full-size HP laptops. Most full-size models need 45W, 65W or more, and their sockets take different plugs, so the 4.0x1.7mm pin will not fit them. A 30W supply also cannot keep up with a larger laptop's demand. For full-size HP machines, Mascom International stocks 45W, 65W, 90W and 135W HP adaptors, and our team can match one to your model on WhatsApp.
Is it worth replacing the charger on an old HP Mini in Kenya?
For KSh 1,400, the HP 30W 4.0mm Laptop Adaptor is usually worth buying if the netbook still powers on and its screen and keyboard work. Many families keep an HP Mini as a child's first computer for typing practice, offline lessons and music. A netbook will not run heavy modern software, so keep it to light tasks. If the machine has other faults, such as a cracked hinge, weigh those repairs first. Our staff can test the adaptor on your netbook at the Kimathi Street shop.
Who should buy the HP 30W 4.0mm Laptop Adaptor, and who should skip it?
Buy the HP 30W 4.0mm Laptop Adaptor if you own an HP Mini netbook with a 4.0x1.7mm socket and a 19V rating on its old charger label. It suits parents, students and field workers who want a light charger for a small machine. Skip it if your HP has a USB-C charging port, because the HP Spectre 65W USB-C Laptop Adaptor at KSh 2,200 fits those. Skip it too for a full-size laptop with a slim blue-tipped plug, where the HP 45W and 65W Blue Pin adaptors apply.
How do I keep the HP 30W 4.0mm Laptop Adaptor working when I carry it every day?
Most adaptor failures start where the cable meets the plug, so the way you carry the HP 30W 4.0mm Laptop Adaptor matters more than how often you use it. Students moving between hostel and lecture hall at JKUAT, or riding a matatu to Thika, should coil the cable in wide loops and never bend it sharply at the plug. Keep the brick dry during the long rains, since water and mains power do not mix. A small zip pouch keeps brick, cable and cord together.
Technical Specifications
Core Function and Power Output
- 19V output — the voltage HP Mini netbooks with a 4.0mm socket expect, shown on their original charger label as 19V.
- 1.58A current — the most the adaptor can deliver at once; the netbook draws only the current it needs at any moment.
- 30W total power — 19 volts multiplied by 1.58 amps, matched to the low power draw of a small netbook rather than a full-size laptop.
- AC-to-DC conversion — the brick changes mains electricity from the wall into the steady direct current a netbook battery can store.
- Use while charging — run the netbook for typing, reading and browsing while its battery refills in the background.
- Overnight charging — leave it plugged in with the lid shut, and the netbook is ready for school or work the next morning.
- Replacement for a lost or dead charger — gives a netbook with a working screen and keyboard a second run of useful service.
Compatibility and Connector
- 4.0x1.7mm pin — a round barrel 4.0mm wide with a 1.7mm inner opening, matching the charging socket on compatible HP Mini netbooks.
- HP Mini netbooks — the small, low-power HP machines this adaptor is built for, once popular with students and travellers.
- Series check — HP Mini models changed plugs over the years, so compare your old charger's label before ordering.
- Rating check — look for 19V and 1.58A on the old label; matching voltage protects the netbook's charging circuit.
- Not for full-size HP laptops — larger HP models need 45W or more and a different plug, so choose another adaptor in our range.
- WhatsApp confirmation — send your netbook model or label photo to +254 708 852 521 for a fit answer before you pay.
- Socket shape matters most — a plug that looks close but is a fraction too wide or narrow will not charge, or will sit loose.
Build and Design
- Two-piece design — the brick and the mains cord separate, so a damaged cord can be replaced without buying a whole new adaptor.
- Attached DC cable — one fixed lead from brick to netbook, with nothing extra to misplace between home and school.
- Light, small brick — a 30W unit is noticeably smaller than a 65W laptop charger, suiting a school bag or handbag.
- Slim plug head — sized for the narrow socket on a netbook, so it seats fully without forcing or wobbling.
- Gentle warmth in use — the brick may feel warm while charging, which is normal; keep it uncovered on a hard surface.
- Brand new stock — never a used or salvaged unit, so the cable, plug and casing come to you unworn.
Inclusions and Support
- Adaptor brick with fixed DC cable — finishes in the 4.0x1.7mm pin, ready to connect to your HP Mini.
- Detachable mains power cord — connects the brick to the wall; confirm the plug type on WhatsApp before dispatch.
- 6-month Mascom International warranty — covers manufacturing defects, with claims taken at our Nairobi CBD service desk.
- Pay when it arrives — check the adaptor on delivery before handing over payment, in any of Kenya's 47 counties.
- Fit advice before purchase — our team checks your netbook model or old label so the pin and voltage match.
Package Contents
Inside the package you will find the HP 30W 4.0mm Laptop Adaptor brick with its fixed DC cable ending in the 4.0x1.7mm pin, together with a detachable mains power cord for the wall socket. Nothing else is needed to start charging your HP Mini. Because Kenyan buildings use 3-pin UK-style sockets, ask us on WhatsApp to confirm the plug type on the mains cord before dispatch, so it suits the outlet at home, school or the office.
Warranty
Mascom International backs the HP 30W 4.0mm Laptop Adaptor with a 6-month warranty covering manufacturing defects under normal use, for example a unit that delivers no power to a compatible netbook. Bring the adaptor and your receipt to our Nairobi CBD service desk at Old Mutual Building, Kimathi Street, where all claims are handled.
