6-24V to 5V 3A USB DC-DC Buck Step-Down Converter

This step-down (buck) power supply module converts its input voltage of 6V to 24V to a fixed 5V USB output at up to 3A continuous output current.

It is ideal for providing a regulated 5V USB output to charge your iPhone, Android phone, tablet or any other USB-powered device. It can be powered from a 6V, 9V, 12V or 24V battery, solar panel, wind generator or other power source.
