Power Up: Your Complete Source for Laptop AC Adapters

Your charger performs the critical function of turning AC power from a wall outlet into a DC voltage that can charge your laptop’s battery - which is why it is also known as an AC adapter or power adapter. Without it, your laptop has no power supply, and its functionality will last only as long as its current battery charge. That is why a lost or damaged laptop charger is one of the greatest frustrations of modern technology, and why many people also choose to pick up a spare charger for travel.

Fortunately, Micro Center has you covered, with a complete selection of the best selling laptop wall chargers to get your computer powered up. Wondering how to select the right AC power adapter for your computer? Read up on the key factors ahead.

How to Choose the Right Laptop Adapter

OEM vs. Third Party: Original equipment manufacturer (OEM) chargers come from the same manufacturer as your laptop, such as Dell, Apple, ASUS, Lenovo, and others. If you are in doubt about which charger to choose, an OEM model is always a good bet. On the other hand, we also feature a large selection of universal chargers from reputable third party brands, with features that make them compatible with a huge range of different laptops.

Model Compatibility: Even OEM chargers are not always compatible with every model from a particular company, so check to verify which specific models a given charger supports. Universal chargers typically don’t list specific models, so look at other specs such as wattage and voltage to determine which one fits your needs.

Output Wattage and Voltage: Every laptop charger uses a specific wattage and voltage output to charge the battery, and it is very important to choose the correct specs to avoid damaging your laptop. If you have your original charger or laptop manual on hand, it should list the wattage and voltage requirements. Universal models often offer multiple voltage and wattage settings that can be controlled with a switch.

Input Voltage: Electrical outlets in North America produce standard 120 volt AC power, but on other continents, the voltage varies widely by country. If you are planning to take your charger on international trips, choosing a model that can accommodate multiple input voltages can save you from needing to use a converter.

Connector Type: Different laptop power adapters use different types of connectors - the little piece on the tip of the power cord that plugs into your laptop. Universal laptop chargers often include a selection of adapter pieces for the connector, allowing you to choose the one that fits your laptop. In some cases, such as Apple MagSafe connectors, you will need to purchase a charger designed specifically for that connector type.

Warranty: To ensure that you get the best performance from your charger, many models include a limited warranty that will replace your charger in the event of a manufacturing defect.
