1A/2A Switching USB Charge Current Tester USB load Resistor Test

USB Charge Current Tester  USB load Resistor Test 1A/2A Switching
A new version of a comprehensive upgrade , improvements are as follows :
1. Add a large current Rocker Switch( Rocker Switch longest life expectancy ) , you can switch directly 1A and 2A current discharge.
The board is a native switch interfaceAnd printing 1A / 2A corresponding position ,
ensure that the switch contact resistance stability and smaller, not the kind of casually in the front or back plate welded up trouble !
2. Discharge resistor with a5 Europe truly customized winding resistance( More costly ) , the test result is more accurate ( closer 2A and 1A),
legacy is 5.1 ohm , when displayed on a 5.1V power supply 2A insufficient discharge 1.9XA, 1A displays 0.9XA.
3. Also increased the size of the discharge resistorDiameter 7.9mm original bold to 8.3mm, never cut corners, to ensure enough power .

Tips:
1.when the load is working , winding resistance due to large current would have a very, very high temperatures , soDuring use ,
and just a short time after use , you can absolutely do human contact winding resistance , to avoid being scalded !
And do not allow contact with flammable materials tester to avoid fire ! Always short course on high alert !
2. taking into account the special nature of resistance around the wound , the use of electricity in the first period will be a little white smoke and odor after the phenomenon , because outside the paint also contains a very small amount of water , electricity high temperature heat, the water evaporates to form white smoke phenomenon, outside by high-temperature baking paint odor phenomenon , after a period of use disappear completely.This phenomenon is bound to occur , this is normal , do not worry it will damage the load tester , ease of use .
