Q&A Q: Why is the battery capacity 10000mAh but the rated capacity is 5800mAh? A: Because the input voltage of devices such as mobile phones is 5V. In the power bank, the original voltage of 3.7V is boosted to 5V before output. The output capacity is therefore 7400mAh (3.7V*10000mAh/5V=7400mAh). There is energy loss during step-up and step-down control, and the energy conversion rate is more than 75%. Finally, the nominal capacity is about 5800mAh. (7400mAh*75%=5550mAh).
