This multifunctional tester can detect the charging state of the electric appliance in real time, and the indicators such as voltage, current and power are clear at a glance. Features: The tester is widely used in the quality inspection of Type-C port 3C digital peripheral products. It is the first choice for digital players and electronic lovers. It has many functions: screen rotation, data storage, quick charge recognition, capacity and energy detection, temperature measurement, screen off, precision measurement, wide voltage range and low internal resistance. For the detection of recharger, power bank and other charging equipment, a variety of data are displayed on one screen to meet diversified testing requirements. Adopts a 0.96 inch IPS color LCD display with a 160-degree wide view, high brightness and long service life. Let you see from any angle to appreciate the color bright, exquisite and natural display picture. 4 bits precision, higher accuracy, smaller date detection error, more accuracy. With the function of power off storage, when the power bank is power off, the capacity and energy data can be stored, which is convenient for subsequent inspection, and convenient for capacity and energy measurement of the power bank. Clearly understand the load impedance and current discharge power, better understand the load usage range, usage will be more convenient and faster. With thermometers function, freely switch between Celsius and Fahrenheit; and it also can measure the quality of the recharger. Exquisite and compact, convenient to carry, with USB cap, dust-proof and fall-proof, more beautiful.
