A 26800mAh power banktypically refers to the total energy it can provide over its lifespan.
This is because the charging process is not 100% efficient and other factors come into play.
For example, a 26800 mAh power bank can theoretically provide a total charge of 26800 milliampere-hours.
However, its crucial to note that this capacity is not directly transferrable to your mobile devices.
When you charge your gear with a power bank, the charging process is not 100% efficient.
In addition to the efficiency factor, there are also power losses associated with the voltage conversion process.
Power banks typically have a higher voltage than the unit being charged.
To accommodate this voltage difference, the power bank converts the voltage, resulting in some power loss.
Furthermore, power banks have their own internal circuitry and components that consume a small amount of power.
This power is not available for charging your devices and further reduces the effective capacity.
While its not an exact science, there are some calculations you could make to get a rough estimate.
This information is usually provided in milliampere-hours (mAh) on the devices specifications or in the user manual.
Lets assume your machine has a battery capacity of 3000 mAh for our calculations.
On average, the charging efficiency is around 70-80%.
Lets take 75% as the charging efficiency for our calculations.
Account for power loss during transfer
During the voltage conversion process, there is some power loss.
This loss is typically around 10-15%.
For our calculations, lets assume a power loss of 12%.
Understanding these factors will help you make a more accurate estimation and maximize the usage of your power bank.
Charging Efficiency:
The charging efficiency of both the power bank and your unit plays a significant role.
The higher the power loss, the lower the effective capacity available for charging your gadget.
This dual power consumption reduces the overall charging capacity of the power bank and can result in fewer charges.
Charging Conditions:
The environmental conditions in which you charge your gadget can also affect the charging efficiency.
It refers to how effectively the power bank transfers its stored energy to your rig during the charging process.
When choosing a power bank, its important to consider its overall charging efficiency.
Charge your devices in moderate temperature environments, as extreme temperatures can negatively impact charging efficiency.
Choose the Right Power Bank:
Consider your specific needs and usage patterns when selecting a power bank.
Choosing the right power bank will ensure it meets your charging requirements efficiently.
This helps calibrate the battery and maintain its optimal performance.
Avoid frequently charging or discharging it partially, as it can affect the overall battery life and capacity.
Store and Handle with Care:
Protect your power bank from extreme temperatures, moisture, and physical damage.
Handle it with care to prevent accidental drops or impact that could damage the internal components.
Use Power Bank Frequently:
Regularly using your power bank helps maintain its battery life.
Unplug After Charging is Complete:
Once yourdevice is fully charged, disconnect it from the power bank.
Recharge the Power Bank Promptly:
After using your power bank, recharge it as soon as possible.
Ideally, aim to recharge the power bank within a few days of use.
Now that weve covered various factors and considerations, lets summarize the key insights in the concluding section.
Stay connected and powered up wherever you go, enjoying the convenience of portable charging for your mobile devices.
