How many mAh external battery do I need?
To determine how many milliamp hours (mAh) you need from a power bank, you need to consider the battery capacity of the devices you intend to charge and how often you need to charge them. load them.
For example, if you frequently use a smartphone with a 3,000 mAh battery and want to charge it several times without recharging the external battery itself, an external battery with a capacity of 10,000 mAh or more would be suitable.
Also consider the efficiency of the external battery and the power loss during charging, which typically reduces effective capacity by about 10-20%.
What capacity for a good external battery?
A 20,000 mAh power bank can last a varying amount of time depending on the device being charged and its battery capacity.
For example, if you use it to charge a smartphone with a 3,000 mAh battery, you could theoretically charge it about 6-7 times (20,000 mAh / 3,000 mAh = 6.67). However, the actual number of charges will be slightly lower due to the inefficiency of the charging process and the performance of the power bank.
What size power bank do I need?
A 5000mAh power bank can last a different duration depending on the battery capacity of the device. For example, with a 3000 mAh smartphone battery, you can expect around 1-1.5 charges.
Actual performance may vary due to external battery efficiency and specific power consumption of the device being charged.
A higher mAh in a power bank generally means it has a larger capacity, allowing it to store more energy and charge devices more times before needing a recharge.
However, a higher mAh generally means that the power bank will be larger and heavier. Choosing mAh should balance your capacity needs with the convenience of size and portability. For example, a higher mAh is better if you need to charge multiple devices or need extended use, but if portability is more crucial, a lower capacity power bank might be more suitable.
With a 10000 mAh power bank, you can charge a smartphone with a 3000 mAh battery about 3-4 times. This estimate assumes that the power bank is fully efficient and does not lose significant power during the charging process.
In reality, the actual number of charges might be slightly lower due to energy losses and varying efficiency rates.
