What is the difference between a power bank and a portable battery?
There are significant differences in functions, uses, and characteristics between power banks and portable batteries. The following is a detailed analysis of the differences between the two:
1. Definition and purpose
(1) Power bank:
Power bank, also known as "external battery", "external battery", "backup battery", etc., is a portable charger that integrates power supply and charging functions. It is mainly used to provide power support for handheld digital devices such as mobile phones, tablets, digital cameras, MP3, MP4, etc., and solve the charging needs of these devices when they are outdoors or have insufficient power. Mobile power supplies usually have the characteristics of large capacity, multi-purpose, small size, long life, safety and reliability.
(2) Portable battery:
The “portable battery” referred to here may cover a broader concept, including but not limited to portable energy storage power sources. Portable energy storage power supply is a small energy storage device with a built-in lithium-ion battery. Its battery capacity is usually between 100Wh-3000Wh and can stably output AC/DC voltage.
It can not only power high-power household appliances such as hair dryers, electric vehicles, and rice cookers, but also provide power support in emergency disaster relief, outdoor operations, and other scenarios. In addition, portable batteries may also include other types of portable energy storage devices, such as car emergency starting power supplies.
2. Functional characteristics
(1) Power bank:
Mainly used to charge small handheld devices, such as mobile phones, tablets, etc.
Usually equipped with a variety of power adapters to adapt to the charging needs of different devices.
It has the characteristics of large capacity, portability, safety and reliability.
(2) Portable battery (taking portable energy storage power supply as an example):
Can power a wider range of devices, including high-power household appliances and outdoor equipment.
Equipped with more types of interfaces, such as USB, Type-C, PD, etc., and supports car chargers and solar panel charging.
High capacity and high power, covering more mobile application scenarios.
3. Summary
To sum up, there are obvious differences in the definition, purpose and functional characteristics of mobile power supplies and portable batteries. Mobile power supplies are more focused on providing power support for small handheld devices, while portable batteries (such as portable energy storage power supplies) have a wider range of applications and stronger power supply capabilities. When choosing, users should choose the appropriate device based on their own needs and usage scenarios.
