A small power bank generally refers to a compact, portable device designed for charging electronic devices on the go. These external batteries generally have capacities ranging from 5,000 mAh to 10,000 mAh. They are suitable for charging smartphones and small gadgets, but may require more frequent charging if used for larger devices or for multiple charges.
The best power bank capacity depends on individual needs and usage. For most users, a capacity between 10,000 mAh and 20,000 mAh provides a good balance between portability and charging capacity.
Higher capacities, such as 20,000 mAh or more, are ideal for those who need expanded charging capacity for multiple devices or for longer trips.
A 20,000 mAh power bank can typically last a considerable amount of time before needing to be recharged, depending on the power consumption of the devices it charges. For example, it can charge a smartphone with a 3,000 mAh battery about six to seven times.
However, actual usage times may vary depending on factors such as the efficiency of the power bank and the type of devices being charged.
A 30,000 mAh power bank is considered high capacity and can provide multiple charges for larger devices or multiple devices over extended periods of time. This capacity is suitable for users who need expanded charging capabilities, for example during long trips or to power multiple devices.
An 8000mAh power bank is considered smaller than other high capacity options.
It’s enough to charge smaller devices like smartphones or tablets multiple times, but may not be enough for extended use without recharging the power bank itself.
