USB Current Voltage Capacity Tester Volt Current Voltage Detect Charger Capacity Tester Meter Mobile Power Detector Battery Test

Feature: 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. Color: Green. Rated Power: 5W-10W. Technology: Ceramic Composition. Resistance: 1A-2A. Type: Fixed Resistor. Size: 7.3cm x 1.8cm x 1.0cm. Features: and high quality. It can measure current and voltage of the power supply equment with USB port. Plug and play, no extra power supply needed. The voltage and current will be displayed circularly. Small sized, easy and convenient to carry. Specifications: Workable range: 4 - 30V, 0 - 3A. Resolution: voltage 10mV, current 10mA . Error range: voltage
