What is output of power bank?

1) The industry standard cell(s) used within the Power Bank commonly output 3.7 Volts. This voltage has to be boosted up to 5 Volts via the Power Bank’s internal circuitry as this is the standard voltage of a USB interface. Energy losses during this boosting phase are around 10-15\%.
