Name: KW-202usb current and voltage detector
It can easily measure the output voltage of USB port and the working current of equipment
Small size, no power supply and other accessories, plug and play
It can also detect whether the output voltage and current of USB charger is up to standard
Suitable for factories, laboratories and users
Technical indicators:
Working range: current (0-2.5a) to detect whether the voltage of mobile phone charger can reach DC5V
Working range: u = 3 ~ 7.5V, I = 0 ~ 2.5A
Resolution: voltage 10mV, current 1mA
Error: voltage < ± 1% current < ± 2%
Full scale voltage drop: 200mV (when measuring current)
Working temperature: 0-60 ℃
The electric energy tester adopts a new generation of 4-bit half double integral cycle conversion integrated circuit, equipped with precision band gap reference source, with accurate range, high precision, stable operation, reliable performance, strong anti-interference ability and high temperature resistance. It can be used to measure the power supply or consumption of USB interface, mobile phone charger, U disk and other products.
This product can measure the voltage of USB power supply device when it is empty and loaded, and the voltage and current of USB terminal when it works.
The current and voltage cycle display is simple, convenient and practical.
Small and easy to carry, without additional power supply
Quantity: 1pcs
