The rated battery capacity is the capacity of the internal batteries, while the real capacity is the capacity of charge that the power bank is able to transfer. That may sound confusing but isn’t.
Under well defined conditions this is often referred to as the Rated Capacity as the battery capacity is likely to be different under different temperature, discharge rates and prior use. An alternative unit of electrical charge. Product of the current strength (measured in amperes) and the duration (in hours) of the current.
Real capacity refers to the usable power that a power bank delivers to your devices. This value is typically lower than the rated capacity due to several factors, including energy loss during the transfer process. Factors Affecting Real Capacity Several factors contribute to the difference between real and rated capacity:
This term is often printed on the power bank and provides a snapshot of its potential. What is Rated Capacity? Rated capacity is the theoretical maximum amount of charge a power bank can store, usually measured in milliampere-hours (mAh). For instance, a power bank labeled with 10,000 mAh is supposed to hold that much charge.
Yes, the terms “rated capacity” and “advertised capacity” are used interchangeably when talking about power banks. Both terms refer to the maximum amount of electric charge a power bank can theoretically store and supply, calculated based on the nominal voltage of the lithium-ion batteries inside, typically 3.7 volts.
As we have learned, battery voltage is the missing link that allows us for direct comparison between a set of battery systems. But the most important specification for your application will always be the rated energy. Jolien Despeghel Jeroen Tant
