Q&A

For example:

 

Q: Why the battery capacity is 40000mAh, but the rated capacity is 21600mAh?

 

A: Because the input voltage of devices such as mobile phones is 5V. Inside the power bank, the original 3.7V will be boosted to 5V before output.

So the output capacity is 29600mAh ( 3.7V*40000mAh/5V=29600mAh).

There will be energy loss in the step-up and step-down process, and the energy conversion rate: more than 73%.

 

Finally, the rated capacity is about 21600mAh.(29600mAh*73%=21600mAh).

 

 

 

This T133LP/T134LP mobile power bank is a high-end intelligent spare power supply designed specifically for mobile digital products. The DC is converted to DC, and the input part uses a high intelligent lithium battery.
