Find a Replacement Universal Power Adapter for Your HP Laptop

There are a number of reasons why you might be looking to get a cord for your HP laptop. Even if you didn't misplace the original one, it is wise to have a backup power adapter or charger, especially if you work with your HP device in more than one location.

Are adapter and chargers for laptops available in different voltages?

Adapters and chargers are available with a number of different voltages, offering compatibility with many different laptops. The voltage options available range from 5 volts to as many as 25 volts. A tablet computer or basic laptop typically uses less voltage to charge and receive power than a gaming laptop because of all of the options included in the device.

How do you determine the right adapter for your laptop?

Factors related to universal power adapters or chargers for your HP computer include supplied voltage, wattage requirements, and plug shapes and sizes. Some recommended steps to help you find the right accessory are as follows:

  • Find your model number: Every computer, like ones from HP, has a model number that tells you some basic information about the computer. You can use the number to identify what accessories, like battery chargers or adapters, are compatible with your HP laptop.
  • Find wattage requirements: Besides the voltage required, your HP device has a specific wattage that is required to avoid damaging the internal components when giving its battery a charge.
  • Pick a compatible adapter: Using the model number and the wattage of your HP computer, you can identify an adapter or charger that will work with your device. Often, replacement adapters and chargers will list a series of model numbers that they are compatible with to facilitate easy comparisons. If available, make sure that the model number of your HP device is listed in this compatibility section to prevent any possible issues that can occur if the wattage or voltage is not right.
What is the difference between AC and DC power adapters?

The main difference between AC and DC power adapters is the type of electrical current they supply. AC current switches polarity, meaning that the positive and negative sides of the circuit will flip repeatedly. In the United States, the rate of this flipping is 60 hertz, meaning that every second, the positive and negative sides will flip 60 times. DC doesn't flip polarity as AC does. As a result, the electricity is always flowing through the circuit in the same direction.
