Brand new and high quality.
It's normal when welding resistance may occur heated white smoke or odor phenomenon.
New products can freely be switched with a switch, very convenient and easy to use.
USB load resistance, is mainly to do discharge test, if the charger or mobile power supply output current is 2A, load meter power is 5V * 2A = 10W, if the output current is 1A, then the power load is 5V * 1A = 5W.
Switch and usb interface design.
Rated Power: 5W-10W.
Technology: Ceramic Composition.
Type: Fixed Resistor.
Size: 7.3cm x 1.8cm x 1.0cm.
Note: Discharge resistors will become hot, the temperature at 80 ~ 85 ℃, please pay attention to anti-scald.
You can easily test mobile power charging treasure, cell phone charger, USB power supply output current is standard, as long as the USB port to the resistance above the line. And can move the power and USB power adapter to do the aging test.
