Electronic load tester can monitor voltage, current and other data of DC power adapters, USB and Type C devices. It can also complete discharging and aging, test battery internal resistance, and test the capacity of the power bank. With BT connection, it can achieve remote control of mobile phone and computer. Besides, it's upgraded with 4-wire connection for more accurate measurement. With multiple protection, it's safe and easy to use! Features: [Electronic Load Tester] -- 200V wide voltage, 30A large curren, 150W or 180W discharging power for option. It can monitor Voltage, Current, Capacity, Electric Energy, Power, Temperature, Resistance, Discharging Time and other data of the DC power adapters, USB and Type C devices. It can accomplish discharging and aging, test battery internal resistance, and test the capacity of the power bank. [BT Connection, Remote Control] -- Supports APP in mobile phone (compatible with Android/ iOS) and wired/ wireless BT computer connection, easy to set and measure via APP or software remote control. [4-Wire System] -- Upgraded version of 4-wire connection, the voltage measurement will not be affected by the voltage drop of the wire. And it's also compatible with 2-wire conneciton for meeting your different needs. [LCD Color Screen] -- 2.4-inch large screen provides clear wide visual display. Easy to switch different display interface via functional button. [4 Operating Modes] -- Constant Current (CC), Constant Voltage (CV), Constant Power (CW), Constant Resistance (CR). Easy to switch according to different needs. [Cooling Fan for Heat Dissipation] -- Intelligent temperature-controlled fan with low noise, high speed and strong power can effectively keep the tester operating during long time. It's suitable for long-time discharging or aging testing in factories. [Multiple Protections] -- It Features over-load and over-current protections. And with external NTC temperature probe, easily realizing internal and external temperature measuring, and Features high temperature protection.
