Notes:
Without batteries and charging wires!!!
When the battery performance is poor and the voltage drops too fast to 3V, it will immediately turn to 00.
Even if the battery voltage goes back after standby, the power will not rise back.
Therefore, it is not recommended to use batteries with large internal resistance, long storage time and have been used for many times.
Due to the light and screen setting difference, the items color may be slightly different from the pictures.
Please allow slight dimension difference due to different manual measurement.
