Universal 90W Laptop Power Adapter
This universal AC adapter delivers up to 90W across a 12-24V auto-switching output. It accepts 100-240V input at 50/60Hz and includes eight standard DC tips covering brands such as HP, Lenovo, Dell, Toshiba, Acer, Sony and Samsung. The ultra-slim housing measures 17mm thick for easy travel.
Travellers needing one charger for multiple laptops
Suits users who carry several notebooks with barrel connectors ranging from 3.0mm to 7.9mm centre-pin sizes. Not for laptops that charge exclusively via USB-C Power Delivery or proprietary magnetic tips not listed among the supplied connectors. Buyers needing more than 90W total output should look elsewhere.
Fits in a compact kit with dual USB charging
The adapter frees a wall outlet by powering a laptop and two mobile devices simultaneously through dual 5V 2.1A USB ports. It requires only a standard IEC C7 or C8 mains lead for the chosen region (US, EU, UK, AU, KR). The 90% efficiency rating reduces heat in confined bags.

Questions about this item
Which laptop tip do I need to already have for the adapter to fit my machine?
The adapter ships with eight DC tips including 4.8×1.7 mm for 19 V HP and Delta models, 4.5×3.0 mm with pin for 19.5 V HP, 7.9×5.5×0.9 mm for 20 V Lenovo, 4.8×1.7×28 mm for HP Ultrabook, 3.0×1.0 mm for Samsung Ultrabook, 11×5.6 mm square tip for 20 V Lenovo and 7.4×5.0 mm for 18.5 V models.
Can I keep using my existing barrel tip from another charger with this unit?
Yes, any tip that matches the listed dimensions and voltage such as 4.8×1.7 mm 19 V or 7.9×5.5×0.9 mm 20 V will work because the adapter auto-switches between 12 V and 24 V up to 6 A.
How do I confirm the adapter is delivering power correctly after I plug it in?
The laptop charging LED should light and the two USB ports each supply 5 V 2.1 A for phones or tablets while the DC output shows the selected voltage between 12 V and 24 V.
