FAQ
Q : Why the battery capacity is 50000 mAh, but the rated capacity is only 32500 mAh? (Why it shows a capacity lower than 50000mAh when I test it?)
A : 1. Energy Conservation Law The unit of measuring the power of the power bank is not only the "mAh", but also the "mWh"(voltage V * capacity )
Since the standard lithium battery voltage of the power bank is 3.7V, the current charging voltage of mainstream mobile phones and computers, or other mobile devices is the standard 5V voltage of the USB interface. The mobile power supply must be boosted to 5V before charging the mobile phone.
For example :
The normal energy of a power bank with a capacity of 50000 mAh is 50000mAh * 3.7V = 185000mWh. After the booster circuit outputs 5V, the output capacity becomes 3.7V / 5V * 50000mAh = 37000mAh.(37000mAh*5V=185000mWh)
2. Energy Consumption During Charging
During the boosting process of the mobile power supply, due to the loss of the booster circuit itself, it cannot output 100% of all energy, and the conversion rate is related to the output current. Normally, when outputting 1A current, the conversion rate will be higher than when outputting 2A.
The conversion rate of the entire mobile power industry is basically in the range of 60% -70%.
So the Conversion Rate in 60% -70% and the Rated Capacity in 30000mAh-35000mAh is reasonable.
