Finding the correct laptop charger is essential for battery health and motherboard stability. Whether you need a 65W Type-C adapter for office work or a 280W high-wattage power brick for an MSI gaming rig, we have you covered. Backed by 20 years of retail experience in Sham Shui Po, our technical team provides on-site voltage testing and precise connector matching to ensure you get the exact AC adapter for your specific device.

Brand Compatibility & Technical Specifications

We stock one of the widest selections of AC adapters in Hong Kong. Below is a quick reference guide for our most common OEM-grade replacements:

Brand Wattage Range Common Connector Sizes (OD x ID)
ASUS 65W - 280W 4.0x1.35mm / 6.0x3.7mm (ROG Series)
Acer 45W - 180W 3.0x1.1mm / 5.5x1.7mm
Dell 45W - 130W 4.5x3.0mm / 7.4x5.0mm (Smart Pin)
HP 45W - 150W 4.5x3.0mm (Blue Tip)
Lenovo 65W - 300W 4.0x1.7mm / Square Tip (Slim Tip)

Important Note (Limitation): While "universal chargers" with interchangeable tips seem convenient, they often lack the precise voltage regulation required by high-end laptops. For devices drawing over 90W (especially gaming laptops), we strongly recommend our brand-specific or OEM-grade adapters to prevent motherboard VRM (Voltage Regulator Module) damage.

Frequently Asked Questions (FAQ)

Q: Can I use a charger with a higher wattage (e.g., 90W) on a laptop that only requires 65W?
A: Yes. Your laptop will only draw the current (Amps) it needs. A higher wattage charger will run cooler and is perfectly safe. However, you must never use a charger with a lower wattage than required, as this will cause the adapter to overheat and potentially fail.

Q: How do I know which connector tip my laptop uses?
A: Connector sizes are measured by their outer and inner diameters in millimeters. Since visual estimation is prone to error, we highly recommend bringing your laptop to our physical store. Our technicians will use digital calipers to find the exact fit. Alternatively, you can WhatsApp us your exact laptop model number for an instant match.
