USB Volt Amp USB Output Can Measure USB Mobile Tabs Charging / Load Volt and Current RED Display

Feature: 1.The tester uses a new generation of power four and a half double integral cycle conversion IC, with a precision bandgap reference, range accuracy, high precision, stable and reliable performance, strong anti-interference ability, high temperature can be used for measuring USB powered or power consumption of an interface, cell phone chargers, U disk and other products. 2.It can be used to measure the empty USB-powered devices, voltage loads, USB terminal equipment working voltage and current. 3.Current and voltage cycle, easy to use and practical. 4.Compact and easy to carry, no additional power supply. Specification: Scope of work: Current (0-2.5A) can detect standard mobile phone charger voltage DC5V Operating Range: U = 3 ~ 7.5V I = 0 ~ 2.5A Resolution: Voltage 10mV Current 10mA Error: voltage <± 1% // current <± 2% Full scale drop: (when measuring current) 200mV Working temperature: 0-60 Celsius Product size: 52*20*15mm Include: 1 x USB Tester

Specification:Test voltage range: 3.5-7.0 VTest current range: 0-3AOperating temperature: 0-60 ℃Resolution: Voltage 10mV current 1mA, error: voltage <± 1% current <±Use:1. Apply to test if the mobile in normal charging or not: Connect detector, the normal output power of computer USB port is 5V, current is 0.5, check the current, if the current is too low, it indicates that the phone is not charging.2. It can test if the charger meet the standard or not, it will show the output voltage and current.3. It can test the consumtion and supply of USB port and U disk, also, it can measure USB powered equipment when they are no-load voltage or load voltage, and load current of USB devices.Details of USB current and voltage tester:
