    While some laptops may be able to charge using a USB-A power bank, most will require a power bank with USB-C, AC, or DC output. [2]
    • USB-A ports are rectangular and often have a three-pronged symbol next to them.
    • USB-C ports are small and ovular.
    • AC ports look the same as the outlets you find in the walls of buildings.
    • DC ports are small and circular with a single prong in the middle.

    Power banks will require you to push a power button so the battery does not waste power through constant output. The power button will often have small LEDs or a power symbol that lights up to indicate that the power bank is on.

    A universal power adapter is a charger that comes with tips of different sizes and can supply different amounts of power based on the computer it is charging. While the adapter is meant to be “universal”, many newer laptops such as those that charge through USB-C will not be supported.
    • Generally, universal power adapters tend to work with Windows computers that have circular charging ports.

    When purchasing a universal adapter, be sure to check the reviews to see if it is safe for use. Cheap or faulty equipment can damage your laptop, so it might be worth buying a slightly more expensive product to ensure your computer’s safety.
    • While it is generally safe to use a high quality third party power adapter for your laptop, it is always safest to use a charger from the manufacturer, so consider using the included charger if possible.

    If your car does not have an outlet or port that works with your laptop, you will need an adapter and a charger to charge your laptop.
    • You could also use a power inverter, but they are much clunkier and can be significantly more expensive than an adapter.
