Patent Number: 201320653928.0
This patent is about ten years old. The USB wall socket has yet to become popular on the market. The energy storage unit was added to this invention due to the major flood in my region. The power in my city was gone, and many people were trapped, but no way to call for help. The battery inside allows user to charge their phone when there is no power in the building. This function is crucial for emergencies.
