• Warning 1：When using the positioning hole, due to the upside and down side of PCB board voltage is different, avoiding the copper sheet together to cause a short-circuit. 
• Warning 2：The unstable voltage on car, must use wide input to ensure that your precious electrical safety. Must be at 9 ~ 30 v wide input to be used in the car. This product can do
• Warning 3：This version is suitable professional who will use the multimeter. The output voltage can be adjusted 1V~6V , with line voltage compensation data loss! Some data line is very long, especially a few meters long, wire loss can reach 1v, so they need the adjustable version. such as NOTE phones of Samsung, charger voltage is 5.2v

Package Includes:

• 1 x Step Down USB Step-down Power Module
