A portable energy storage device capable of simultaneous multi-port discharge and power allocation method, the device including multiple charging output ports, all or part of which have different preset power distribution priorities, enabling the user to determine the priority sequence of multiple power-receiving devices according to actual needs when using the device. Furthermore, when multiple charging output ports are all connected to power-receiving devices and the sum of the required power of the power-receiving devices exceeds the maximum power that the device can provide, all ports can still operate at their respective preset minimum power. If there is remaining power, the remaining power is preferentially allocated to the charging output ports with higher priority. Furthermore, when the number of charging output ports connected to power-receiving devices changes, the device reallocates power, thereby achieving dynamic power adjustment and enabling the device to operate at its maximum output power whenever possible.

A portable energy storage device capable of simultaneous multi-port charging and discharging and method for allocating charging and discharging power, wherein the energy storage device includes a power allocation unit, at least two power input ports, and at least two charging output ports, wherein the power allocation unit is used for allocating power to the power input ports connected to the charging device and the charging output ports connected to the receiving device, and the maximum permissible operating power of the energy storage device in charging and discharging mode is defined as P.sub.max. By distributing the power of the power input port and the charging output port, the portable energy storage device is enabled to meet the demand for simultaneous charging and simultaneous power supply, ensuring a good user experience.
