DC-DC LM2596 Synchronous Step Down Power Module With Voltage Display 4.5-24V

Description:
This module can be applied to reduction voltage field that input voltage is higher than output voltage, such as accumulator, power transformer, DIY adjustable regulated power supply, laptop power supply on car and industrial equipment.

Features:
1, Can be used on car to charge your phone, MP3, MP4, PSP, etc. Simple and convenient.
2, As power supply for electronic equipment when there is no suitable power supply.
3, Good voltmeter when test system working voltage.
4, Very easy to set various voltage range needed when doing project or experiment.
