Abstract: A preparation method of coffee cherry tea is provided, including following steps: taking ripe and full fresh coffee berries, washing, draining and peeling the fresh coffee berries to obtain coffee peels; drying the coffee peels immediately until a moisture content is in a range of 20% to 30% to obtain dried coffee peels; fermenting the dried coffee peels for a range of 2 days to 3 days to obtain fermentation products; and baking the fermentation products for a range of 3 minutes to 4 minutes under a temperature in a range of 100 Celsius degree (° C.) to 180° C. to obtain the coffee cherry tea. The coffee cherry tea obtained by the preparation method has a mellow and sweet taste, which effectively solves the problem of sour and astringent taste of the existing coffee cherry tea.

Abstract: A rechargeable battery includes a battery body and a connector plug. The battery body has a recess, a circuit board and a cell. The circuit board is electrically connected to the battery cell. The connector plug is pivotally connected to the battery body and electrically connected to the circuit board. The connector plug is foldable to be received in the recess. Accordingly, the connector plug is pivotally connected to the battery body and is foldable to be received in the recess, so the battery body can be charged by means of the connector plug connected to an external power supply, thereby improving convenience in using the rechargeable battery.

Abstract: A composite connection socket includes a metal housing, an insulative main body, a first row conductive terminal and a second row conductive terminal. The metal housing includes an accommodating space formed therein, and the insulative main body is received inside the accommodating space. The insulative main body includes a first side plate, a second side plate and a base; the first side plate and the second side plate are arranged corresponding to each other and protrude from the base. The first row conductive terminal is arranged on the first side plate and complies with a micro USB communication protocol interface. The second row conductive terminal is arranged on the second side plate and complies with a lightning standard interface. The composite connection socket is able to commonly accommodate two cable connectors of different standards of a micro USB connector or a lightning connector inserted therein.
