RD AT35 5 Digits USB3.0 Port 3.7-30V 0-4A Range Color LCD Display Voltmeter Ammeter Voltage Current Meter Tester Multimeter Power Bank USB Charger Tester(AT35)

Features

• 1.AT35 is a USB tester to test the voltage and current of a USB-A port, the test range is 3.700-30.000V(voltage), 0-4.0000A(current)
• 2. AT35 adopts 0.96 inch IPS LCD display with 160 degree wide view angle, you can see the data clearly in differnet angle
• 3. AT35 can recognize these charging protocols on the screen: QC2.0, QC3.0, APPLE 2.4A/2.1A/ 1A/0.5A, Android DCP, SAMSUNG
• 4.together with a USB electric load, you can test the capacity of a power bank by discharging it from 100% energy to 0, the use formula to caculate the capacity of the power bank
• 5.you can test the quality of the charger in this way: connect the same load, compare the no-load and with load, the greater the voltage drop, the worse the charger capacity , the worse the quality; if the voltage drop is not obvious or the voltage rises, The better the load capacity of this charger, the better the quality.
