ماژول تستر USB با نشانگر جریان و ولتاژ

Can easily measure the operating current USB port and the output voltage of the device! (Note: it can only accurately display the real-time voltage and current electrical work, do not have the function of the discharge device, which can not be set to a certain voltage discharge current of certain compact, no power, and other ancillary equipment, that is! plug and Play! also detect any USB charger (USB computer, home charger, car charger) charging current and voltage in order to determine the performance and the performance of the charger charging cable to meet the requirements! wide application, any phone, any electronic product, you can use, easy to operate, suitable for factories, exhibition presentations, laboratories and users!
