Understanding Power Bank Capacity: mAh Explained
Power bank capacity is measured in milliampere-hours (mAh), indicating how much charge it can hold. Higher mAh means more charging cycles for your devices. For students, this translates to powering multiple devices or recharging a single device multiple times. A 10,000 mAh power bank might fully charge a smartphone twice, while a 20,000 mAh unit can offer four or more charges.
Consider the battery size of your most-used devices. A typical smartphone has a battery around 4,000-5,000 mAh. A laptop battery can range from 40,000 to 80,000 mAh.
How Many Charges Can You Expect?
To estimate charges, divide the power bank’s mAh by your device’s battery mAh. Remember that some energy is lost during the charging process, so actual charges will be slightly less. For example, a 20,000 mAh power bank might realistically provide around 13,000-15,000 mAh usable energy.
This means a 20,000 mAh power bank could potentially charge a 5,000 mAh phone roughly 2.5 to 3 times. Always factor in a slight buffer for real-world efficiency.
