USB charging current detection load test instrument with toggle switch can be 2A/1A discharge aging resistance -57525
product detail
Product features:
1, using a toggle switch, two-color work light: can directly switch between 1A and 2A current discharge. When switching 1A work, the green light is on. When switching 2A work, the red light is on.
2, large area copper cladding, increase the heat dissipation hole: the back of the expanded copper cladding area, increase the heat dissipation hole. Enhance the heat dissipation function.
3, real 5 ohm wirewound resistor: The discharge resistor is made of custom-made real 5 ohm wirewound resistor (higher cost), and the test result is more accurate (closer to 2A and 1A).
Module use tutorial:
Function switching: When your power output is as large as 1A, switch to 1A gear for testing; when your power output is 2A or above, switch to 2A gear for testing.
Judgment criteria: plug into the USB power supply/mobile power being tested USB output port, 1A work, the green light is on. When switching to 2A work, the red light is on.
Caution:
1, the loaders work, wirewound resistor through the high current, will produce very, very high temperature, so in the process of use, and just after a short period of time, never human contact wirewound resistor, so as not to be burned! Do not let flammable objects touch the tester to avoid fire! In short, be highly vigilant in the process of use!
2, taking into account the special nature of the winding resistor, in the initial use of power for a period of time will appear a little white smoke and odor phenomenon, is due to the outer paint also contains a very small amount of moisture, high temperature heating, moisture evaporation to form a white smoke phenomenon, the outer paint by high temperature baking odor phenomenon, after using a period of time completely disappeared. This phenomenon is bound to occur, belongs to the normal situation, do not worry about the load tester will be damaged, please feel free to use.
