[0016] A method for using a mobile power supply with peripheral power detection feedback, the specific steps are as follows:

[0017] Step 1: When using the power supply, the device to be charged can be connected to the USB interface for charging. When using the USB interface, you can first pull and pinch the clamp to open the clamp, and then pull the second connection cable to shrink the first telescopic rod, so that the second connection cable can be pulled out to facilitate the USB interface to connect the device to be charged. During charging, the voltage, current and remaining power inside the charged device can be monitored in real time through the voltage detection module, the current detection module and the power feedback module, and then fed back to the processor, and then the processor can display it on the display screen for the user to observe;

[0018] Step 2: When using the power supply, since the charging voltage and charging current required by various devices are different, only when the most appropriate charging voltage and charging current are reached can the charging be overheated and the charging efficiency be the highest. At this time, the output voltage and output current of the power supply can be adjusted through the voltage adjustment module and the current adjustment module. When adjusting, the adjustment signal can be sent to the processor through the control panel, so that the processor can control the voltage adjustment module and the current adjustment module to adjust the output voltage and output current of the power supply, so that the power supply can adapt to charging of various devices;

[0019] Step 3: When the power source needs to jump-charge the vehicle battery, it can only open the top cover protecting the upper end of the left terminal first, and the left side is the positive pole. If the left terminal is not opened, the right terminal cannot be opened under the action of the first limit block and the movable rod. When opening the top cover at the upper end of the left terminal first, it is necessary to pull the left movable ring downward so that the arc-shaped card block is stuck in the slot. When the left movable ring moves downward, the top cover at the upper end can contact the terminal, so that the top cover can be opened, and the mounting hole can be leaked. At this time, the mounting rod can be inserted into the mounting hole and fixed by thread, so that the installation of the positive pole of the battery can be completed. Then connect this positive pole to the positive pole of the vehicle battery, and when the left movable ring moves downward, the first magnet and the second magnet will be close to each other, so that the movable rod can be moved to the left by magnetic attraction, so that the rod will no longer be stuck in the first limit block, and the right terminal can be opened at this time, so that it can effectively prevent the negative pole from being connected first and then the positive pole when jumping.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention charges a device that needs to be charged through a USB interface. When using the USB interface, the clamp can be pulled and pinched to open the clamp, and then the second connection cable can be pulled to shrink the first telescopic rod. In this way, the second connection cable can be pulled out to facilitate the USB interface to connect the device that needs to be charged. During charging, the voltage, current and remaining power inside the charged device can be monitored in real time through the voltage detection module, the current detection module and the power feedback module, and then fed back to the processor, which can then be displayed on the display screen by the processor for user observation.

[0022] 2. The present invention adjusts the output voltage and output current of the power supply through the voltage regulation module and the current regulation module. During the adjustment, the adjustment signal can be sent to the processor through the control panel. In this way, the processor can control the voltage regulation module and the current regulation module to adjust the output voltage and output current of the power supply, so that the power supply can adapt to charging of various devices.

[0023] 3. When the left movable ring of the present invention moves, the top cover at the upper end can contact the terminal, so that the top cover can be opened, and the mounting hole can be leaked. At this time, the mounting rod can be inserted into the mounting hole and fixed by thread, so that the positive electrode of the battery can be installed. Then the positive electrode can be connected to the positive electrode of the vehicle battery, and when the left movable ring moves downward, the first magnet and the second magnet will be close to each other, so that the movable rod can be moved to the left by magnetic attraction, so that the rod will no longer be stuck in the first limit block, and the right terminal can be opened at this time, so that it can effectively prevent the negative electrode from being connected first and then the positive electrode when connecting the power.

[0041] A method for using a mobile power supply with peripheral power detection feedback, the specific steps are as follows:

[0042] Step 1: When using the power supply, the device to be charged can be connected to the USB interface 31 for charging. When using the USB interface 31, the clamp 40 can be pulled and pinched to open the clamp 41, and then the second connection cable 30 can be pulled to shrink the first telescopic rod 27. In this way, the second connection cable 30 can be pulled out to facilitate the USB interface 31 to connect to the device to be charged.

[0043] Step 2: When using the power supply, since the charging voltage and charging current required by various devices are different, only when the most suitable charging voltage and charging current are reached can the charging be done without overheating and the charging efficiency be the highest.

[0044] Step 3: When the power supply needs to jump-charge the vehicle battery, the top cover protecting the upper end of the left terminal 6 can only be opened first, and the left side is the positive pole. If the left terminal 6 is not opened, the right terminal 6 cannot be opened under the action of the first limit block 14 and the movable rod 16. When the top cover on the upper end of the left terminal 6 is opened first, the left movable ring 7 needs to be pulled down so that the arc-shaped block 34 is inserted into the slot 32. When the left movable ring 7 moves down, the top cover at the upper end can be in contact with the terminal 6, so that the top cover can be opened, and the mounting hole 12 can be leaked at this time. At this time, the mounting rod 24 can be inserted into the mounting hole 12 and fixed by threads, so that the installation of the positive pole of the battery can be completed. Then the positive pole can be connected to the positive pole of the vehicle battery, and when the left movable ring 7 moves down, the first magnet 13 and the second magnet 17 will be close to each other, so that the movable rod 16 can be moved to the left by magnetic attraction, so that the rod will no longer be stuck in the first limit block 14, and the right terminal 6 can be opened at this time, which can effectively prevent the negative pole from being connected first and then the positive pole when connecting the power.

The mobile power source with peripheral power detection feedback according to claim 7, characterized in that: A third rotating shaft (39) is fixedly provided on the outer surface of the fixed frame (26); a clamp (40) is movably provided on the outer surface of the third rotating shaft (39) via a bearing; a clamp (41) is fixedly provided on one end of the clamp (40); a rubber pad (42) is fixedly provided on the outer surface of the clamp (41); and the clamp (41) is movably engaged with the outer surface of the second connecting cable (30).

9. The method for using a mobile power supply with peripheral power detection feedback according to claim 8, characterized in that: The specific steps include: The first step: when using the power source, the device to be charged can be connected to the USB interface (31) for charging. When using the USB interface (31), the clamp (40) can be pulled and pinched to open the clamp (41), and then the second connection cable (30) can be pulled to shrink the first telescopic rod (27). In this way, the second connection cable (30) can be pulled out to facilitate the USB interface (31) to connect the device to be charged. During charging, the voltage, current and remaining power inside the charged device can be monitored in real time through the voltage detection module (48), the current detection module (50) and the power feedback module (52), and then fed back to the processor (43). The processor (43) can then display the information on the display screen (5) for the convenience of observation by the user. Step 2: When using the power supply, since the charging voltage and charging current required by various devices are different, only when the most suitable charging voltage and charging current are reached can the charging be performed without overheating and the charging efficiency be the highest. At this time, the output voltage and output current of the power supply can be adjusted by the voltage adjustment module (44) and the current adjustment module (46). During the adjustment, an adjustment signal can be sent to the processor (43) through the control panel (3). In this way, the processor (43) can control the voltage adjustment module (44) and the current adjustment module (46) to adjust the output voltage and output current of the power supply, so that the power supply can adapt to charging of various devices; Step 3: When the power source needs to jump-charge the vehicle battery, the top cover protecting the upper end of the left terminal (6) can only be opened first, and the left side is the positive pole. If the left terminal (6) is not opened, the right terminal (6) cannot be opened under the action of the first limit block (14) and the movable rod (16). When the top cover on the upper end of the left terminal (6) is opened first, the left movable ring (7) needs to be pulled downward, so that the arc-shaped clamping block (34) is clamped into the inside of the clamping groove (32). When the left movable ring (7) moves downward, the top cover at the upper end can be brought into contact with the terminal (6), so that the top cover can be opened. The mounting hole (12) is opened, and the mounting rod (24) can be inserted into the mounting hole (12) and fixed by screw thread, so that the positive electrode of the battery can be installed; then the positive electrode can be connected to the positive electrode of the vehicle battery, and when the left movable ring (7) moves downward, the first magnet (13) and the second magnet (17) are brought closer to each other, so that the movable rod (16) can be moved to the left by magnetic attraction, so that the rod no longer blocks the first limit block (14), and the right terminal (6) can be opened, so that it can effectively prevent the negative electrode from being connected first and then the positive electrode when connecting.
