The connector 150 is, for example, a universal serial bus bar, and the cable 120 has a connector pi that conforms to the connector 15A to electrically connect the port 150. Next, the operation mode of the charger 100 will be described with reference to Fig. 2. Fig. 2 is a flow chart showing the transmission of the specific mode of the embodiment. Referring to FIG. 1 and FIG. 2, when the user wants to use a specific type; f-type to charge, a certain button portion on the selection unit 110 must be pressed first, so that the selection unit 110 generates a specific mode signal. The charger 1 (10) generates a power signal (step S201) and transmits the power signal to the wireless transceiver 130. After step S201, the wireless transceiver 130 converts the received power signal into a laser beam 17A and transmits the laser beam 170 for transmission to the mobile device. Next, the charger 1 (10) determines whether the wireless transceiver 130 receives the sensing signal from the mobile device (step S204), and if the wireless transceiver 13 does not receive the sensing signal (ie, the determination result in step S204 is "NO"). Then, returning to step S2〇2, to continuously convert the power 彳§ number into the laser beam 170; conversely, if the wireless transceiver 130 receives the sensing signal (ie, the determination result of step S204 is YES), ❹ Then, the power state of the mobile device 10 has been saturated, and then step S205 is performed to stop generating the power signal. In the case of the mobile device 10, description will be made with reference to Fig. 3. Fig. 3 is a flowchart showing the reception of the specific mode of the embodiment. Referring to FIG. 1 and FIG. 3, first, the mobile device 1 〇 senses the power state of the mobile device 1〇 through the sensing unit 16〇 (step S301), and determines whether the power state is saturated (step S302). When the power state is non-saturated (that is, the determination result of step S3〇2 is "NO"), then it is determined whether the wireless transceiver 140 201015825, ZTW 28253twf.d〇c/n does not receive the laser beam 170 (step S303). If the wireless transceiver 140 receives the laser beam 170 (i.e., the decision result in the step S303 is NO), the mobile device 1 returns to the step S301 to continue sensing the power state. Similarly, when the power state of the mobile device 1 is not saturated (the determination result of step S3〇2 is NO), when step S303 is executed, the wireless transceiver 140 receives the laser beam 170 at this time (ie, If the result of the determination in step S303 is "YES", the wireless transceiver 140 converts the laser beam 170 into a power signal 'and charges the mobile device 1 using the converted power signal (step S304). After step S304 is performed, the process returns to step S301 to sense whether the power state after each charging is saturated and the charging is continued in the unsaturated h state until the power state is saturated. Then, the process returns to step S302. After charging for a period of time, the power state of the mobile device is saturated (that is, the determination result of step S3〇2 is YES), and then it is determined whether the wireless transceiver 140 receives the laser light 170 (step S305). When the device 10 is fully charged, the charger 1 will continue to emit the laser beam 170 because it does not know that the power state of the mobile device 1 is saturated, so that the wireless transceiver 14 will still receive the laser beam 170. (That is, the determination result in the step S305 is "YES"). However, the mobile device 10 does not need to be recharged at this time, that is, the charger 1 does not need to transmit the laser beam 170. Therefore, the sensing unit at this time 16〇 generates a sensing signal, and converts the sensing signal into a laser beam 18 through the wireless transceiver 140, and transmits it to the wireless transceiver 13A to control the charger 1 to stop generating the power letter 201015825 ----- -2 .TW 28253twf.d〇c/n Similarly to the action device (4), the power status is "yes", if the wireless transceiver field beam 170 (ie, the judgment state of step S3〇5 is not enough) At the same time, it is possible to receive the laser = water to charge the binding device 10. ❹ Electric, the village makes the wire mold performance line 1G for charging 3 is suitable for connecting the connector on the mobile device _ connector 1 two-mode = towel The maker's money first presses the selection unit 110 on the charger (10) to cause the charging 11 (10) to generate the normal mode signal, and the connector 121 is engaged with the connector 150. Then the charger is estimated, according to the positive (4) The power signal is transmitted through the age 120 so that the power k number is transmitted to the mobile device 10 through the cable 120. 2 The mobile device H) collects power money through the connector 1D H electrically connected to the recording line (10). This power signal is then used to power the mobile device. At the same time, the sensing unit 160 also senses the mobile device 〇 = power state. If the power state of the line 1G is not saturated, then the 7L (10) will continue to sense the action, and the line will continue to be charged = electric power sand for charging. If the action m (4) power state is full = ^ _ 7 〇 160 will generate a sensing signal and convert to the laser beam 180 for transmission to the wireless transceiver 130 through wireless transmission and reception. When the wireless transceiver 13 on the charging device 100 receives the laser beam 11 201015825 ^2.TW 28253twf.doc/n (10), it means that the power state of the mobile device 1G is the sum, and the charging benefit 100 will stop. Generate a power signal. Thereby, the charger (10) can be stopped from generating power money immediately when the mobile device (7) is fully charged. From another point of view, embodiments of the present invention can be integrated into a charging method' and the charging method is used to charge a mobile device. Figure 4 is a flow chart of a charging method in accordance with an embodiment of the present invention. Please refer to FIG. 1 and FIG. 4, and the domain J includes the steps of the publication. Money, (4) S4〇l will generate a power signal step _ will selectively generate a normal mode signal or special _! #b ° then 'step S4G3 will judge the normal mode signal or feature mode (four) which is generated 'combined corresponding Operating procedures. - If the result of the determination in step S403 is "specific mode signal", step S41G is received. In step S41G, the electric k number is converted into a laser beam in accordance with a specific mode, and the laser beam is emitted in step S4n. Next, in step S412, the laser beam is received and converted into a power signal, and the mobile device is charged with the converted power signal in step S413'. In the step..., the sense line is configured to generate and transmit a sensing signal, wherein if the sensing signal is generated, it indicates that the power state of the mobile device is saturated. If the result of the determination in step S414 is "NO", the mobile device is not saturated, and the process returns to step S41, to continuously convert the power signal into a laser beam; if the result of the determination in step S414 is "YES" The power state of the mobile device is saturated. At this time, when the ❹Ht lin is received, the power generation is stopped to stop charging the mobile device. In step S403, if the determination result #MODE signal of step S403 is "", then step S420 is executed. In step 84, the signal is transmitted to the device by the power signal transmitted by the cable in step S42, and is then charged in the normal mode signal. Then, in step S422, The sensing mobile device determines whether to generate and transmit the sensing signal. L ' o If the determination result in step S422 is "NO", indicating that the power state of the line is not saturated, the process returns to step S42, and the device is known. ν When the power is transmitted from the power to the mobile device through the cable, and the action is continued to be charged.
