USB Load Tester Discharge Resistance USB Charge Current Detection USB Mini Discharge Load Resistor 2A / 1A Switch
A good tool to test your power source capability, support 2A or 1A constant current discharge via USB.
Rated Power: 5W-10W
1.Switch in special boat shape desige,just for a long time usage.
2.Circuit board becomes longer after adding the switch, ensuring better radiating.
3.Blue circuit board looks more advanced than green circuit board.
4.The 5Ω winding resistance is more accurate than before
5.The size of the Discharge resistor becomes bigger than before,change the direct from 7.9mm to 8.3 mm, steady, radiating and more power.
-The red LED lighting indicates that the rated output power reaches the standards, when red LED light is dark and flashing mean that the power supply does not reach the standards.
-When the load dector is working,current flow through the winding resistor, then high temp will be caused. You can not touch the winding resistor immediately to avoid being scalded.
-Due to the small ammount of water contains in the paint, Little smoke and smell will appear after your first usage for a certain time. This is the normal phenomenon that you do not worry about.
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 .
1, when the load is operating, winding resistance due to a large current would have a very, very high temperatures, so in the course, and just a short time after use, can absolutely do human contact winding resistance, to avoid being scalded! And do not let flammable materials contact test device to avoid fire! Short course must be highly vigilant!
2, taking into account the special nature of resistance around the wound, in the initial period will be powered using a little white smoke and odor after the phenomenon, because the outer paint also contains a very small amount of water, electricity high temperature heat, the water evaporates forming white smoke outside by high-temperature baking paint odor phenomenon, after a period of time to completely disappear. This phenomenon is inevitable, is normal, do not worry it will damage the load tester, ease of use.
3. Our combined sales of USB voltage and current detector to be tested, the more intuitive, you can see during the test voltage and current situation.
When the red LED keep on then it means the discharging is working fine, if not then it means the discharge is not reached.
