Abstract: One embodiment of the disclosure provides a rechargeable battery including a shell, a circuit board assembly, a core and an electrode assembly. The shell has a first outer surface. The circuit board assembly is disposed in the shell. The core is disposed in the shell and electrically connected to the circuit board assembly. The electrode assembly is disposed on the first outer surface of the shell and electrically connected to the circuit board assembly. The circuit board assembly is not located between the core and the first outer surface.

Abstract: The disclosure is related to a quick charge battery which includes a battery cell, a cap assembly, a quick charge assembly and an insulating film. The cap assembly protrudes from the battery cell. The cap assembly includes a main body and an electrically conductive member. The electrically conductive member is located on a side of the main body away from the battery cell. The quick charge assembly is located in the main body and is located between the battery cell and the electrically conductive member. The quick charge assembly includes a circuit board and a quick charge connector. The quick charge connector is electrically connected to the battery cell. The electrically conductive member is electrically connected to the battery cell. The insulating film is sleeved on the battery cell and the cap assembly. The quick charge connector is exposed from the main body and the insulating film.

Abstract: The disclosure provides a portable charger including a power supply and an adapter. The power supply includes a battery module, a first terminal set, a voltage control module and a first switch portion. The battery module has an initial voltage. The adapter includes a second casing, a second terminal set, an output connector and a second switch portion. When the adapter is detached from the power supply, the portable charger is in a first state, and the voltage control module adjusts the initial voltage to a first voltage, allowing the first terminal set to output the first voltage; when the adapter is disposed on the power supply, the portable charger is in a second state, and the voltage control module adjusts the initial voltage to a second voltage which is different from the first voltage, allowing the first terminal set to output the second voltage.
