Finding the Right Model of Adapter

Since there are so many different adapters on the market, it’s essential to check which type of adapter a laptop requires before purchase. Most adapters are marketed for specific brands and models of laptops. They will also list the voltage, current, and polarity of the adapter. This way, laptop owners can select the appropriate adapter for their devices. Finding the correct adapter for a laptop means checking the laptop’s model number and power requirements.

  • Get the laptop’s model number. This is usually printed on a small sticker affixed to the underside of the laptop.
  • Get the power requirements for the laptop. This is also printed on a small sticker affixed to the underside of the laptop. It may also be printed near the laptop power port. Look for the amperage and the voltage required.
  • Look up the model number online to find if there are compatible adapters available. The voltage and amperage of the adapter need to match the requirements of the laptop.
  • Compare the connector type of the Dell 290W laptop adapter to any available adapters found online. They need to match to ensure that the adapter can plug into the laptop.
