Abstract
The present invention provides a power bank comprising a battery protection board, controller board, and a host connector. The host connector is compatible with an accessory connector on a fast charger board, and the host connector is connected to the accessory connector for boosting the charging rate of the power bank. The fast charger board connected to the power bank may, for powering laptops and electric bicycles, elevate the output voltage of the power bank to 12V or above. The power bank may further connect with other external components, such as an LED module and a wireless transceiver module, in order to extend the functionality of the power bank.
