People often leave their main chargers at home or in the office and have no access to a plug whilst out shopping or in meetings. Portable chargers can be used to charge not just your mobile phone but anything running low on energy; such as a tablet or a laptop, and are therefore extremely handy to have in your bag or lying around.
