【Kindly Note】: Note 1: The power adapter is actually a fragile electronic component. The internal components cannot withstand knocks. In particular prevent falling from a high place during use and do not throw knock or shake the charger. Rough handling of the charger will damage the internal circuit board and cause malfunctions. Note 2: High temperature will shorten the life of electronic equipment damage the charger and deform or melt certain plastic parts. Do not store the adapter in a cold place. When the adapter is working in a cold environment when the internal temperature rises moisture will form in the charger and damage the circuit board. Note 3: Clean the charging port of the power adapter regularly. Because the plug is prone to fouling after long-term use. If it is not cleaned up in time it will cause poor contact of the plug and even cause the adapter to fail to work. Note 4: Long-term power on will keep the adapter in working condition and affect its service life. Note 5: Pay special attention to the connection of the adapter. The bending angle of the wire should not be too large otherwise the wire may break. The connection of the power adapter should also avoid bending otherwise it will cause poor contact. Note 6: Although the adapters are all broadband operating voltages marked from 100V-240V if the voltage is unstable it will cause damage. Note 7：Due to the different sizes of sockets or power strips please confirm whether the plug size of our adapter can match your socket or power strip before purchasing. Avoid buying the wrong or unsuitable adapter.
