This product needs to be matched with a charger/power bank that supports PD protocol charging and 3A / 5A Type-C data cable to achieve the purpose of charging the laptop.

How to know your laptop power (W/Watt)?

First, you need to know the input power of the laptop. You can look at the bottom of the notebook or the original power adapter, where you can find the voltage and current information, such as "20V=3.25A", which means that the power of the notebook is 65W (20*3.25A).

Then judge whether your charger/power bank is suitable for your notebook according to your notebook power (W/Watt)

How to check the output power (W/Watt) of the charger/power bank?

You can check the back of the charger/power bank or the instruction manual to find its related information, for example, if the information on the charger is "Output: 20V = 3.25A", the output power of this charger is 65W (20 * 3.25 ) , for your 65W/45W laptop, but not for powering a 90W laptop

Why can't cell phone chargers/power banks be used to charge laptops?

First, they usually only support phone charging, not laptop charging

Second, their output voltages and currents are usually very low and do not support laptop-powered

A USB port equipped with an electrical outlet cannot be used to charge the laptop.
