Unplug the charger from electrical outlets and the device when not in use. 

 

Do not drop or cause an impact to the charger. 

 

If the power cable is damaged (for example, the cord is exposed or broken), or the 
plug loosens, stop using it at once. Continued use may lead to electric shocks, 
short circuits, or fire.

the charger. 

 

Do not touch the device or the charger with wet hands. Doing so may lead to 
short circuits, malfunctions, or electric shocks. 

 

If your charger has been exposed to water, other liquids, or excessive moisture, 
take it to an authorized service center for inspection. 

 

Ensure that the charger meets the requirements of Clause 2.5 in IEC60950-

Battery safety 

 

Do not connect battery poles with conductors, such as keys, jewelry, or other 
metal materials. Doing so may short-circuit the battery and cause injuries or burns. 

 

Keep the battery away from excessive heat and direct sunlight. Do not place it on 
or in heating devices, such as microwave ovens, stoves, or radiators. Batteries may 
explode if overheated. 

 

Do not attempt to modify or remanufacture the battery, insert foreign objects into 
it, or immerse or expose it to water or other liquids. Doing so may lead to fire, 
explosion, or other hazards. 

 

If the battery leaks, ensure that the electrolyte does not make direct contact with 
your skins or eyes. If the electrolyte touches your skins or splashes into your eyes, 
immediately flush with clean water and consult a doctor. 

 

In case of battery deformation, color change, or overheating while charging or 
storing, immediately stop using the device and remove the battery. Continued use 
may lead to battery leakage, fire, or explosion. 

 

Do not put batteries in fire as they may explode. Damaged batteries may also 
explode. 

 

Dispose of used batteries in accordance with local regulations. Improper battery 
use may lead to fire, explosion, or other hazards. 

 

Do not allow children or pets to bite or suck the battery. Doing so may result in 
damage or explosion. 

 

Do not smash or pierce the battery, or expose it to high external pressure. Doing so
