You’ll most often see it called an AC adapter, power adapter, laptop charger, or power supply. On this page, chargers come in a few styles and power levels to match different Windows laptops and tablets.

• Connector types: USB-C, round barrel tips, and proprietary magnetic plugs used by some 2-in-1s.
• Power ratings (watts): Common options include 36W, 44W, 65W, 90W, and 100W+.
• Voltage: Many notebooks use 19–20V; some compact devices use 12V.
• Extras: Interchangeable tips, longer cords (like 10 ft), and LED indicators.

Matching the connector and electrical specs to your device can help ensure safe, reliable charging.

There are a few simple ways to check whether your laptop supports USB-C charging.

• Port and markings: Look for a USB-C port with a charging icon or PD label. Your device manual or spec sheet often confirms this.
• Charger and cable: If supported, use a USB-C Power Delivery charger with enough wattage (e.g., 65W or 100W) and a PD-rated cable.
• Other connectors: If USB-C charging isn’t supported, you’ll need a barrel-tip or a proprietary magnetic connector instead.

Since compatibility varies by model, reviewing your device documentation and the charger’s compatibility list can help you choose confidently.

Start by matching what your device originally shipped with, then choose from compatible options in this category.

• Connector type: Identify USB-C, a round barrel tip (sizes like 4.5×3.0mm or 7.4×5.0mm), or a proprietary magnetic plug.
• Voltage and wattage: Match the voltage (e.g., 12V or 19V) and select equal or higher wattage than your original (36W, 44W, 65W, 90W, etc.).
• Cable length and features: Consider longer cords (some are 10 ft), LED status lights, or kits with interchangeable tips if you have multiple devices.
• Compatibility details: Use the product page’s model list and specs to verify support.

These steps can help narrow choices, though exact requirements may vary by model.

A few quick checks can help diagnose common charging hiccups.

• Power source: Try a different wall outlet and remove surge protectors or power strips.
• Cables and connector: Inspect for frays or bent pins; reseat the plug firmly. Clear dust from the port and confirm the tip size is correct.
• Indicators and heat: If your adapter has an LED, note its status. If the brick feels hot, unplug and let it cool.
• Specs match: Ensure the adapter’s voltage (12V vs 19V), connector type, and wattage meet your device’s requirements.
• Cross test: If available, try a second compatible charger or cable.

If problems continue, device hardware or battery health may be involved, and professional support can help.

Check your laptop’s power needs, then compare them to the 65W option.

• Original specs: Match the voltage and meet or exceed the original wattage. If your device came with 45W, 65W often provides overhead; if it needs 90–100W, 65W may charge slowly or not under heavy use.
• Connector type: Confirm the plug (USB-C, specific barrel size, or proprietary magnetic) is correct.
• Device class: Many thin-and-light notebooks and 2-in-1s fall in the 36W–65W range, while performance models may require more.

Review your model’s documentation and the charger’s compatibility notes to help avoid under- or over-specifying.
