Referring to fig. 10 and 11, in some embodiments, a USB interface 122 is disposed at an end of the first circuit board close to the tail cover 130, a USB mounting hole is disposed on the tail cover 130, and the USB interface 122 may extend to an outer side of the tail cover 130 away from the barrel 110 through the USB mounting hole to facilitate connection with an external device.

Referring to fig. 1 and 3, in some embodiments, a lamp 112 for indicating the charging state is provided on the barrel 110. The user can determine whether flashlight 100 is in a charging state according to the on/off of indicator light 112 or the color of indicator light 112, so as to prevent flashlight 100 and charger 200 from being burnt out because the user cannot know when flashlight 100 and charger 200 are in poor contact. The display state change of the indicator 112 to reflect the charging state belongs to the technology commonly used in the art, and the detailed structure and principle thereof are not described herein.

The embodiments of the present application have been described in detail with reference to the drawings, but the present application is not limited to the embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application. Furthermore, the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
