With switch USB charging current detection load test instrument can be 2A/1A discharge aging resistance

1. When the load is working, the winding resistance will inevitably produce very, very high temperature due to large current, so in the use of the process, and just used in a short period of time, do not contact with the winding resistance, so as not to be scalded! Do not allow flammable objects to touch the tester to avoid fire! In short, the use of the process must be highly vigilant!

2. Considering the particularity of winding resistance, a little white smoke and peculiar smell will appear after the first use of electricity for a period of time, which is due to the fact that the outer paint also contains a very small amount of water. The phenomenon of white smoke is formed by high temperature heating and evaporation of water. The outer paint is baked at high temperature to produce peculiar smell, which disappears completely after a period of use. This phenomenon is bound to occur, which is a normal situation, do not worry about the load tester will be damaged, please rest assured to use.

③2. Discharge resistance is used customized 5 ohm wire wound resistance(Higher cost), the test results are more (closer to 2a and 1a), the old version is 5.1 ohm resistance, when 2A is discharged on a power supply less than 5.1V, it will display 1.9X a,1a will display 0.9X a.

When your power output is 1A, switch to 1A gear for testing; When your power output is 2a or above, switch to 2a gear for testing.

Judgment criteria are: insert the USB output port of the detected USB power supply/mobile power supply. The red light is continuously on to indicate that the power supply reaches the corresponding rated output standard, and the red light is not on or flashes to indicate that the rated output standard is not reached.

Note: The in stock baseplate is a green baseplate.

It is a new version of USB discharge load device with switch that can directly switch 1A/2A current. Its own factory assembly line production, output and performance are not comparable to small workshops, excellent. 3 yuan a promotion
