2.4-inch TFT color display, the battery level is displayed in the upper right corner of the screen._x000D_ Built-in 600mAh lithium battery, the working current is about 160mA, and the standby time is about 4 hours._x000D_ Built-in lithium battery charging management circuit. The charging time is about 2 hours._x000D_ Use TYPE-C interface to charge, very convenient_x000D_ The charging voltage is 5V. When charging, the red light indicates that it is charging, and the green light indicates that it is fully charged._x000D_ _x000D_ Instructions:_x000D_ 1. Long press the button to power on, long press again to power off_x000D_ 2. Press the button once to start scanning, press the button again to pause scanning_x000D_ 3. The waveform on the top of the screen shows all the wifi signals in the 2.4G frequency band. ly, only the wifi signal with the strongest signal is displayed. However, if there are multiple signals at the same frequency point, they will be displayed in numbers below the corresponding coordinate scale. For example, if the number 5 is displayed, it means that the same frequency point is occupied by 5 wifi. The waveform below the screen corresponds to the waveform of the 5G signal. The interpretation method is the same as above. Since there are more frequency points of 5G signals, there is no way to mark all the frequency points on the coordinate scale._x000D_ Type: WIFI signal scanner_x000D_ Interface: TYPE-C_x000D_ Charging voltage: 5V_x000D_ Material: ABS_x000D_ colour: White_x000D_ _x000D_ Package Contents:_x000D_ 1 x Host_x000D_ 1 x TYPEC Charging Cable_x000D_ _x000D_ Only the above package content, other products are not included._x000D_ Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
