Power bank

A power bank, comprising:

• a first shell;
• a battery;
• a circuit board, electrically connected to the battery, wherein the battery and the circuit board are disposed inside the first shell;
• a second shell, disposed on a side of the first shell;
• a connection terminal, disposed on the second shell, wherein the connection terminal comprises an input end and an output end electrically connected to the input end;
• an electrical connection assembly, electrically connected to the input end of the connection terminal and the circuit board, wherein the power bank is able to be in a first state;
• and in a case where the power bank is in the first state, the output end of the connection terminal is disposed facing the first shell;
• a first rotation structure, connected to the connection terminal and the second shell, so that the connection terminal is able to be rotated relative to the second shell;
• and
• a second rotation structure, connected to the first shell and the second shell, so that the first shell is able to be rotated relative to the second shell.
