1 x USB power current and voltage tester
new arrive USB Load Resistors Mobile Power Aging Resistance Module 1A 2A charge current detection
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.More about itemusbmobile powerload resistorpower resistoragingresistance measuringcurrent dischargeresistor
