Finding the Right Type of Laptop Charger

You need to know the exact type of adapter that your laptop requires before making the purchase. There are many different types of adapters available. They may have the same power voltage and amperage but different connector types or the same connector type but different power. Thus, they are incompatible with each other. Most of the laptop chargers are only compatible with specific laptop brands and models. The laptop model number, power requirements of the adapter, and connector type of adapter are required in order to find a compatible replacement power supply.

• Find the laptop model number, which is often on a sticker on the bottom of the laptop.
• Find the laptop's power requirements, which are also usually printed on a sticker at the backside of the laptop. Sometimes it might be printed on the power port of the laptop. Take note of the voltage and amperage required.
• See which charger is compatible by checking out the Laptop model number from the website by searching with the laptop model. It is important that the voltage and amperage of the replacement charger must match written on the laptop or match with the faulty (original) adapter.
• Also, make sure that the charger connector tip matches the connection port on the laptop; otherwise, the adapter won't work if it cannot connect to the laptop even if specification else is ok.
