How many charges does a 5000 mAh external battery do?
A 5000mAh power bank can provide multiple charges depending on the capacity of the device being charged. For example, if you have a smartphone with a 2500 mAh battery, a 5000 mAh power bank could provide up to 2 full charges (5000 mAh / 2500 mAh = 2).
Actual number of charges may be slightly lower due to energy losses and inefficiencies during the charging process.
How long does a 5000mAh battery last?
A 50,000 mAh power bank can last much longer in terms of the number of times it can charge devices before needing to be recharged itself.
Actual usage time depends on the devices ability to charge. For example, if you use a 50,000 mAh power bank to charge a device with a 5,000 mAh battery, it could theoretically provide up to 10 full charges (50,000 mAh / 5,000 mAh = 10). The practical number of charges may be lower due to losses in efficiency and charging capabilities of the external battery.
How to calculate the autonomy of an external battery?
A 5000mAh power bank works by storing electrical energy in its internal battery and then transferring that energy to your device via a USB output.
When you connect a device to the power bank using a compatible USB cable, the stored energy is transmitted to the device’s battery and charges it.
Charging efficiency and speed depend on the power rating of the external battery and the charging requirements of the device.
With a 10,000 mAh power bank, the number of charges you can get depends on the capacity of the device to charge.
For example, if you are charging a device with a 2500 mAh battery, a 10000 mAh power bank could provide around 4 full charges (10000 mAh / 2500 mAh = 4). The actual number may be slightly lower due to energy loss during the charging process.
The number of charges an external battery can perform depends on its capacity and the ability of the device being charged. To estimate the number of charges, divide the external battery capacity (in mAh) by the device battery capacity.
For example, a power bank with a capacity of 20,000 mAh could theoretically charge a device with a 4,000 mAh battery up to 5 times (20,000 mAh / 4,000 mAh = 5).
Actual number of charges may be slightly lower due to efficiency losses.
