No, not all HP laptop chargers are the same. Although some HP laptop chargers are interchangeable, they differ in wattage, voltage, connector size, and charging technology. A charger that works with one HP laptop may not be suitable for another, even if both laptops belong to the same brand.
Before buying a replacement HP laptop charger, it's important to check its specifications rather than relying on appearance alone.
Are HP Laptop Chargers Interchangeable?
Yes, some HP laptop chargers are interchangeable, but only when they meet the laptop's power and connector requirements.
There are four important factors to consider:
-
Voltage (V): The charger's output voltage must match the laptop's specified requirements.
-
Wattage (W): The adapter should provide at least the power required by the laptop.
-
Connector Size: The charging plug must fit the laptop's power port correctly.
-
Smart Pin Compatibility: Some HP laptops use an identification pin to recognize a compatible power adapter.
For example, two HP laptops may both require 65W chargers but use different connectors. This means their chargers are not necessarily interchangeable.
Are HP Laptop Chargers Universal?
No, HP laptop chargers are not universally compatible with every HP laptop.
HP laptops use different charging connectors and power requirements depending on their model and generation.
Common HP laptop charger connector types include:
| Connector Type | Common Characteristics |
|---|---|
| 4.5 × 3.0mm Smart Pin | Small barrel connector, often identified by its blue tip |
| 7.4 × 5.0mm Smart Pin | Larger barrel connector, commonly used on older HP models |
| USB-C Power Delivery | Used by compatible modern HP laptops that support USB-C charging |
| Model-Specific Connectors | Used by certain laptops with specialized power requirements |
Even when the connector fits, the charger's electrical specifications and identification features must also be compatible.
Can I Use a 90W HP Charger Instead of a 65W Charger?
Yes, in many cases, a compatible 90W HP charger can replace a 65W charger.
A higher-wattage adapter does not automatically force the laptop to consume 90W. The laptop draws the power it needs.
However, you must confirm that the voltage, connector, polarity, and HP Smart Pin requirements match.
Using a lower-wattage adapter can be more problematic. For example, using a 45W charger with a laptop designed for 65W may result in slower charging, reduced performance, or a power adapter warning.
How Do You Find the Right HP Laptop Charger?
Before purchasing a replacement HP laptop charger, follow these steps:
-
Check your laptop model: Find the exact model or product number on the laptop or in its system information.
-
Read the old adapter label: Look for output voltage (V), current (A), and wattage (W).
-
Identify the connector: Check whether it uses a 4.5mm blue-tip plug, a 7.4mm barrel connector, or USB-C.
-
Verify compatibility: Match the replacement adapter with the laptop's supported specifications and charging requirements.
-
Check product details: Review the seller's compatibility information before ordering.
If your original charger is missing, use your laptop's exact model number to check the manufacturer's recommended adapter specifications.
Can You Charge an HP Laptop With Any USB-C Charger?
Not necessarily. A USB-C port does not always mean the laptop supports USB-C charging.
For compatible HP laptops, the charger should support USB-C Power Delivery (USB-C PD) and provide an appropriate power profile.
For example, a laptop requiring 65W may not charge correctly from a basic 20W phone charger. Similarly, a USB-C cable must support the required charging power.
Always check the laptop's USB-C charging specifications before using a different adapter.

Final Thoughts
So, are all HP laptop chargers the same? No. While certain HP chargers can work across multiple models, not every adapter is interchangeable or universal.
The safest approach is to choose a replacement charger with the correct voltage, sufficient wattage, suitable connector, and supported charging technology. Checking these details before buying can help protect your laptop and prevent charging problems.
