o
overheating. The fan operates automatically when the internal temperature
exceeds a safe threshold, with minimal noise.

associated with lithium batteries.
•
Is the product's actual output capacity the same as listed in the User Manual?
The stated capacity in the manual refers to the rated capacity of the battery. However,
due to efficiency losses during energy conversion, the usable output capacity may be
slightly lower than the listed value. This is a normal characteristic of all battery-powered
devices.
