FAQ

1、Different composition:Charger Composed of a stable power supply (mainly a stable power supply, stable working voltage and sufficient current) plus the necessary constant current,
voltage limit, time limit and other control circuits; Power adapter is a small portable electronic equipment and power conversion equipment of electronic appliances, it is composed of
shell, transformer, inductor, capacitor, control chip, printed circuit board and so on.
2、Different current modes:Charger: The constant current and voltage limiting charging system is used, and the general charging current is about C2, that is, the 2-hour charging rate
is used;Power adapter: From AC input to DC output, indicating power supply, input and output voltage, current and other indicators.
3、Different characteristics:Charger: It is normal for the battery to have a slight temperature rise in the late charging period, but if the battery is obviously hot, it means that the charger
cannot detect that the battery is saturated in time, resulting in overcharge, which is harmful to the battery life; Power adapter: The correct power adapter requires safety certification,
and the power adapter with safety certification can protect personal safety and prevent dangers such as electric shock and fire.

A: It may be due to excessive load, high ambient temperature, or poor heat dissipation of the adapter,If the problem persists, you may need to replace the adapter with a better heat dissipation performance.

Which may be caused by poor interface contact, insufficient input voltage, or damage to the internal electronic components of the adapter. Here we provide solutions:
Reinsert the power adapter plug into the power socket and check whether the interface plug is in good contact,Check whether there is a problem with the input voltage of the power
adapter. If it is normal, there may be electronic components damaged inside the adapter and electronic components need to be replaced.

The transformer is a key component of the power adapter and acts as a safe isolation between the primary circuit and the secondary circuit. Therefore, there are strict requirements for
the transformer skeleton material and thickness, and the insulation tape layer should meet the requirements of strengthening the insulation between primary and secondary schools.

Products obtained safety certificates such like CE GS cUL PSE UKCA SAA KC CCC CQC BSMI and so on.

Obtained safety certification standard such like UL60601、IEC60601、IEC60335、IEC61558、IEC62368、UL1310、GB4706、GB4943.

Yes. Passed IS09001, 1S013485,IS014001,1S04500,EU BSCl Social responsibility .
