USB Voltage Amps Power Meter Tester Charging System Tester, Test Speed of Chargers, Cables, Capacity of Power Banks

Description

When you have a charger, data cable or power bank, you probably have these questions below,  

- Is the charger really outputting as much power as described? 
- If the charger is not original, will it overcharging or overloading my cellphone? 
- Is this cable good enough to deliver 1.5A or 2A I want? 
- The power bank seems not that capacity as described, does it? 

Now you have portable and easy use device to find the answers, moreover, you can test almost everything about electronics as long as they are using USB charging. 

New Generation IC Used. 
Used a new generation of power four semi- double loop integral converter 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 the interface, mobile phone 
charger, U disk and other products.
