A portable energy storage device capable of simultaneous multi-port discharge and a power allocation method. The energy storage device is equipped with multiple charging output ports, some of which have different preset power allocation priorities. This allows the user to determine the priority sequence of multiple power-receiving according to needs when using the device. The invention ensures that when multiple charging output ports are all connected to power-receiving devices and the sum of 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. When the number of charging output ports connected to power-receiving devices changes, the device reallocates power, achieving dynamic power adjustment and enabling the device to operate at its maximum output power whenever possible.
