Choosing a Compatible Laptop Power Adapter
Laptop computers make life and work easier. You can carry your laptop anywhere you go, allowing you to work from home, the coffee shop, and even when traveling. However, your laptop needs battery power to keep you on the go, and a damaged or lost adapter can be more than a problem.
What Is a Universal Power Adapter?
A universal power adapter is a laptop charger that can work across multiple devices. Just like the original adapter, universal chargers convert AC power to a single DC voltage for smaller devices such as laptops to use. However, unlike the power adapter from your laptop manufacturer, universal chargers come with a variety of tip designs. This allows users to connect different laptop models from different manufacturers.
What Factors Should You Consider?
Choosing the right AC adapter for your laptop can be quite challenging. Before you get one, there are a number of points you should bear in mind.
- Connector design: Not all laptops will have the same connector. Even within a single brand, you'll find notebooks that use different plug sizes.
- Output value: Find out the voltage requirements of your laptop. AC adapters have varying voltage (V) outputs, and it's important to avoid damage by using the right voltage for your computer. The general rule is to choose an adapter that matches the rated input voltage of your laptop. The adapters amperage, on the other hand, needs to be equal to or exceed the amperage the laptop requires.
- Portability: The size of the AC adapter and length of the cord can affect portability. For users who travel a lot, a smaller charger is more convenient. However, choosing one with a noticeably short cord is often only ideal if there are lots of outlet options.
What Are the Benefits of a Universal Adapter?
With a universal laptop power adapter, you can charge all the laptops in your home, whether they have individual chargers or not. Some of the reasons why you should consider getting a universal laptop adapter are:
- Multiple connectors: Universal laptop power adapters come with different charger tips. Some feature four-way X connectors or six-way star connectors with multiple plug sizes and types, with others having up to 12 connectors. This allows you to connect laptop models from different manufacturers, including HP, Dell, and Lenovo.
- Versatility: Laptop power adapters with a certain voltage, like 12V, aim largely to work with 12V DC power sources or AC power. The adapters are also for outputting different voltages to satisfy the multiple voltage requirements, and some allow polarity to switch to match each device's specifications.
- Stable power supply: The chargers feature industry-standard 12V interface sockets and can deliver of up to 90W of power continuously.
