In this way, when the base 210 slides in the slide groove 111 to the end provided with the first fixing portion 112, the charging head 200 is fixed on the power source body 100; when the base 210 slides in the slide groove 111 to the end away from the first fixing portion 112, the charging head 200 can be taken out from the slide groove 111, thereby improving the convenience of the mobile power source 10.

[0047] The first fixing portion 112 can be detachably connected to the second fixing portion 211 by snapping, plugging, hooking, magnetism or other means. Specifically in this embodiment, one of the first fixing portion 112 and the second fixing portion 211 is set as a first card block, and the other is set as a first card slot. Specifically in this embodiment, along the extension direction of the slide slot 111, the length of the slide slot 111 is greater than the sum of the length of the base 210 and the length of the first fixing portion 112; that is, when the base 210 moves to the end of the slide slot 111 away from the first fixing portion 112, the base 210 can be moved out of the slide slot 111.

[0048] Optionally, the contour shape of the first card block and the contour shape of the first card slot are adapted, and both are set to be U-shaped. In this way, by increasing the length of the first card block and the first card slot, the contact area between the base 210 and the power source body 100 is increased, ensuring that the charging head 200 can be stably fixed in the locking position, thereby improving the reliability of the mobile power source 10.

[0049] As shown in FIGS. 1 , 2 and 5 , in one embodiment, a first wire groove 113 is provided on the outer wall of the power source body 100, and the first wire groove 113 is connected to the other of the two first closed ends and is used to receive the charging cable 300. Specifically in this embodiment, the charging cable 300 is passed through the base 210 and is electrically connected to the charging interface 220. The length of the charging cable 300 is adapted to the length of the first wire groove 113. In this way, when the base 210 moves to the locked position, the charging cable 300 is in a tensioned state, one end is located in the housing 110, and the other end is located in the slide groove 111, and the middle part of the charging cable 300 is received in the first wire groove 113, which reduces the probability of interference between the charging cable 300 and external objects and improves the practicality of the mobile power source 10.

[0050] Specifically in this embodiment, the slide groove 111 and the first wire groove 113 are both disposed on the outer cylinder 116 .

[0051] As shown in FIG. 1 , FIG. 3 and FIG. 4 , in one embodiment, the mobile power supply 10 further includes a first protective cap 400, which is mounted on the power supply body 100. When the base 210 slides to a locked position in the slide groove 111, the first protective cap 400 can be selectively covered on the charging interface 220. In this way, when the mobile power supply 10 is not in use, the first protective cap 400 can be covered on the outside of the charging interface 220 to play a protective role, thereby improving the reliability of the mobile power supply 10.

[0052] Specifically in this embodiment, the first protective cap 400 is provided with an integrally formed first connecting portion, the first connecting portion is clamped between the outer cylinder 116 and the face shell 117, and the first protective cap 400 and the first connecting portion are both made of silicone material.
