I've a Bluetooth Receiver and a MP5 Decoder, both of those require 5V. I need to set those in single box. So i using a USB mobile phone charger rated 5V 1A. While i connect those two devices parallel with 5V 1A , Voltage just drop below 4V. But i need to use single power supply. What would i do?

Calculate the sum of the currents required by the two devices and select a power supply with a greater current rating than that value.
