Maximum quantity available reached.

Adjustable USB 5V 1A/2A/3A Battery Capacity Voltage Discharge Load Resistor.

Designed in accordance with Ohm's Law and connected in parallel by a different switch, a new type of resistor can be created to discharge the USB electronic load resistor. When all switches are open, they are 2.2 ohms / 10 W, 4.7 ohms / 10 W, and they are connected in parallel. Two types of resistors can generate almost 3A discharge current at 5V.
The actual current is based on Ohm's law: I = U / R Parallel resistance calculation formula: R = 1 / (1 / R1 + 1 / R2 + ... + 1 / Rn) K1 = 4.7 ohms / 10 watts, K2 = 2.2 ohms / 10 watts The load device is working, due to the high current caused by the winding resistance, will produce a very very high temperature, so in the use of the process, just use the finished product in a short time, absolutely can not expose the metal metal radiator parts, to avoid scalding! Do not contact flammable items with the tester to avoid fire! Must be highly vigilant during use! Taking into account the specificity of heat resistance, after some time of initial use, some white smoke and odor will appear, because the external paint contains little moisture, high temperature electric heating, evaporation of water to form a white smoke phenomenon, resulting in high temperature paint odor The outside phenomenon completely disappeared after a period of use. This phenomenon is unavoidable and it is a normal situation, this will not effect device operation. Please rest assured that load application: Can easily test the mobile power charging treasure, mobile phone charger, USB power output current, such as compliance, as long as the connection to the above USB. It can be used for aging test of mobile power supply and USB power adapter. The aging resistance test will be very hot and the temperature is controlled at 80 ~ 85 °C. Please take care to prevent burns. Size: 6

Tips:

When the loader is working, the winding resistance will inevitably produce a very very high temperature due to the large current. Therefore, in the short period of use and just after use, the human body should not be exposed to the heat dissipation part of the golden metal. Being burned! Also, do not allow flammable materials to come into contact with the tester to avoid a fire! In general, be very vigilant during use!

Taking into account the special characteristics of the heating resistor, the phenomenon of odor will occur after the initial use of the power for a period of time, because the exterior paint is subjected to high temperature baking to produce an odor phenomenon, and completely disappears after a period of use. This phenomenon will inevitably occur. It is normal. You don't have to worry about the load tester being damaged. Please feel free to use it.
