1. Using toggle switch, two-color work lights: 1A and 2A can be directly switched current discharge. When the switch 1A work, the green light. When the switch 2A work, the red light.
2. Large area copper, increase the cooling holes: the back of the expansion of the copper area, increase the cooling hole. Enhanced cooling function.
3. True 5 ohm winding resistance: The discharge resistance uses a customizable true 5 ohm winding resistance (higher cost), resulting in more accurate test results (closer to 2A and 1A).
Function switch: When your power supply maximum output is 1A, then switch to 1A file to test; when your power output is 2A or above, switch to 2A file for testing. Judgment criteria: Insert the USB output port of the detected USB power supply / mobile power supply, 1A work, the green light. When the switch 2A work, the red light. Note: 1. The work of the loader, winding resistance due to high current, will inevitably produce very, very high temperature, so in use, and just use a short time, So as not to be burned! Do not allow flammable materials to touch the tester to avoid fire! In short the use of the process must be highly vigilant! 2. Taking into account the resistance around the particularity of the initial use of electricity for some time after the emergence of a small white smoke and odor phenomenon is due to external paint also contains a very small amount of water, power high-temperature heating, water evaporation white smoke, Paint by high-temperature baking smell, after the use of a period of time completely disappeared. This phenomenon will appear, is a normal situation, do not worry about damage to the load tester, please rest assured that use.
