When your charger or power bank has multiple ports, the power output is not always distributed equally among them. So how do we find out how much power we’ll get out of each port when used simultaneously?
Check the box or user manual
The device manufacturer usually shares their products’ multi-port output in user manuals. But this only applies when you already own the power bank or charger. What if you are just looking for one? Check device manufacturer’s website.
Check device manufacturer’s website
On the device manufacturer’s website, they usually have a portion showing the device’s multi-port output. Here’s how it looks.
But what if those information are too hard to find on the website? Check the product info here in Power Radix.

On our website here in Power Radix, when you go to any product page, you will see a tab named Ports. Under the Ports section, you will see the individual charging and multi-port charging.
How to read multi-port output specifications?
For demonstration purposes, we’ll be using the UGREEN Nexode 12000mAh Power Bank. Based on the examples above, the USB-C port is capable of 100W output, while USB-A is capable of 22.5W output. If we only use the USB-C port to charge a laptop, we’ll get the full 100W. But if use both the USB-C and USB-A ports, the device will only output 10W each.
It is also important to note that even if the laptop only requires 45W and was plugged in the USB-C port, while the mobile phone was plugged in the USB-A port, the output 10W each would still be the same if two ports are used simultaneously.
Remember that the multi-port output will always depend on the device’s manufacturer. So make sure to check the box or user manuals.
If you need more than 10W of output for each port, you can browse our list of power banks and chargers.
