When it comes to selecting the right charging solution for your USB-C device, there are a few things to keep in mind.
First, Power Delivery rating is not the same as power bank rating. A power bank rated at 60W, for example, may refer to the the total output of all ports. Just because it includes a USB-C port, does not necessarily mean that port supports Power Delivery and will output 60W on that one port alone. Instead, keep an eye out for a charging solution that includes a USB-C port with a specific Power Delivery rating of up to 60W. Next, watch out for the voltage supported by the charger. Most only support a few fixed voltages which you’ll want to verify are supported by your device for the fastest charge.
In order to ensure you are getting the most from your charge source, be it a USB-C power bank or power station, it’s best to take a look at the adapter that came with your device and match the ratings with those of the charging device. Otherwise you may get stuck with a slower than expected charge rate.
