If you own an ASUS TUF Gaming laptop and wish to change your charger or get a backup, one of the most crucial things to check for is the 150W charger pin size. If you choose the wrong connector size, your device may not charge correctly, your charger may not fit, or even hardware damage may occur. The correct pin size for the ASUS TUF 150W charger, model compatibility, replacement buying tips, and possible issues are all covered in this tutorial. Whether you’re an IT support specialist, computer enthusiast, or gamer, we’ll help you make an informed decision.

What is the pin size of the ASUS TUF Gaming 150W Charger?
The pin measurements of the ASUS TUF Gaming 150W charger are 2.5 mm for the inner diameter and 5.5 mm for the outside diameter. This barrel-style connector is found on many ASUS TUF models, especially the mid-range and high-performance gaming laptops.
However, it’s important to confirm the specs for your individual model. The power input requirements of some TUF series variants, such as those with AMD Ryzen processors or NVIDIA RTX graphics cards, may differ.
How to Measure the Charger Pin’s Size
- Look at the charger’s original label. The voltage, current, and sometimes the connection size are listed (19.5V 7.7A, for example).
- Use a digital caliper to measure the barrel if the label is missing.
- Go to the ASUS support page to determine your exact model.

Suggestions for Buying an Alternative to ASUS’s TUF 150W charger
- Keep utilizing original or approved OEM chargers.
Avoid using generic or unbranded chargers. Although they are less costly, they usually lack sufficient voltage regulation or safety features. - Look for These Specifics:
- It has an output of 19.5V.
- Currently, 150W of electricity at 7.7A.
- Connector: 5.5 x 2.5 mm.
- Seek Safety Certifications
UL, CE, FCC, and RoHS certifications all attest to safe production practices. - Verify the Plug Type (Pin Size).
When making an online purchase, product listings should clearly state the barrel measurements. Some sellers even include close-up pictures or diagrams. - Use Trustworthy Sellers and Brands
ASUS (Representative) Electronics is one of the reliable brands. It offers appropriate advice for universal chargers, Delta, Chicony, and Targus.
Additional Considerations When Choosing a Laptop Charger
Sturdiness and Quality of Construction
To withstand repeated use, a high-quality charger should have a robust shell, reinforced cable joints, and high-quality internal components. Thick rubberized or braided cables are more resilient and less likely to break, particularly if you travel regularly or move your laptop around a lot.
The charger cable’s length
The usual wire length is between 1.5 and 2 meters. Consider longer cables for greater flexibility or shorter cords for small desk configurations, depending on how your workspace is organised.
Portability and Convenience for Travel
A compact and lightweight 150W charger may be useful for frequent travellers. Some third-party manufacturers offer portable, slim-profile chargers without compromising functionality. Seek out foldable plugs and cable organizers.
Managing the Heat
Overheating is one of the most common reasons why chargers malfunction. Verify that the charger has a built-in temperature control system or overheat prevention. Couches, mattresses, and other soft surfaces with poor ventilation shouldn’t be charged.
Real-World Applications: Pin Size’s Significance
In reference to gamers:
Laptops used for gaming use a lot of electricity. Using a charger with the wrong pin size or lower wattage can cause performance throttling, reduced frame rates, or battery loss while playing.
For Students & Professionals:
Using the incorrect adapters could cause random shutdowns when working or giving presentations. Making sure you have the appropriate charger boosts productivity and reduces downtime.
Concerning IT Managers:
Managing the inventory of a fleet of ASUS TUF laptops? The proper pin size ensures seamless device swaps and lowers support tickets.
For an enthusiast of do-it-yourself repairs:
If you feel comfortable making hardware repairs or computer modifications, knowing pin size is crucial when changing power jacks, building custom docks, or adding alternative power sources.
Typical Charger Problems and Fixes
There was no charger found.
Verify that the pin is firmly attached. If not, the barrel may be bent, loose, or misaligned. Try comparing it to another charger or slowly twisting the plug.
Slow charging or no charge:
Check the wall plug and power strip. If another laptop is accessible, use it for testing. Examine the charger brick for LED status indicators. Check for exposed wires, fraying, or heat damage.
The charger warms up quickly.
A little heat is normal, especially when under load. However, significant heat points to potential short circuits, poor construction, or internal degeneration. Replace it immediately to prevent damage to the hardware.
A variable source of power:
Damaged wires or incorrect pin connections typically cause this. Repairing tape is dangerous and only lasts a short time. Replace the charger.
