Why does the capacity differ?
The most important reason is the conversion rate. Most power bank batteries have a voltage of 3.7V, which needs to be boosted to 5V for charging devices. This conversion reduces efficiency to around 74%. Additionally, factors such as heat generation, wire consumption, and self-consumption account for 30%-40% of the power. Hence, a 5000mAh power bank effectively provides about 3321mAh of usable power.
