PROBLEM TO BE SOLVED: To provide a mobile battery.SOLUTION: A mobile battery includes at least two rechargeable batteries, a first voltage adjustment module, and a second voltage adjustment module. The at least two rechargeable batteries are connected in series in head to tail between a first battery side and a second battery side. The first voltage adjustment module and the second voltage adjustment module are connected to the first battery side and the second battery side, and the first voltage adjustment module adjusts a DC charge voltage within a first predetermined voltage range, and can charge the at least two rechargeable batteries. The second voltage adjustment module receives a voltage difference between the first battery side and the second battery side, and, after adjusting as a DC output voltage within a second predetermined voltage range, charges an external device. |
