Abstract
An energy storage device capable of receiving energy using an energy input interface or charging an electronic device using an energy output interface. The energy storage device includes an adapter, an energy storage unit and a charger module. The adapter provides the charger module with an input current, and the charger module provides the energy storage unit with a first current. Otherwise, the charger module provides the electronic device with the input current. When the input current provided by the adapter is higher than a maximum safe current of the adapter, the energy storage unit provides the charger module with a second current. The charger module outputs energy to the electronic device according to the second current to assist the adapter to charge the electronic device. The second current is opposite to the first current.
