Description

1,Monitor the charging status of smart phones. With this multimeter you can easily distinguish poor quality cables and chargers, and find out the reason why your phone charges slowly.
2,Accurately measure the voltage and current of a USB power supply, but it’s smaller, more portable and more convenient than a big and expensive multimeter.
3,Two-line dual-color display of both current and voltage. It is easy to distinguish and you can read both data at the same time.
4, Two output ports make it possible to charge two devices at the same time with one charger. But please be noted: if you connect 2 devices to the detector, the voltage is the same with both output(parallel circuit voltage is equal), and the current is the sum of the two ports.
No battery, no on/off switch, plug and play
