Voltage is like the pressure that pushes electrical current through your device. Most modern power banks are built to output either 5V, 9V, or even 12V depending on the type of charging they support (like standard charging or fast charging). A regular USB-A port usually outputs 5V.
In this article, we will use UGREEN’s power banks as examples to provide an in-depth analysis of the three key specifications of power banks and portable chargers: capacity, output, and input. mAh is the unit that is used to measure the capacity of a battery.
Power bank capacity is typically measured in milliamp-hours (mAh), indicating the total electrical charge the battery can store. However, the voltage of your device and the power bank itself play a crucial role in the actual number of charges you’ll get.
A higher current means a faster charger. For example, a power bank with a 2A capacity will output a charge much faster than 1A. So, if you need to charge your device quickly, consider choosing a power bank like UGREEN 100W 20,000 mAh power bank as it can charge phones, tablets, and even laptops.
