Features:
No need for professional wiring, simple and easy to use, just plug in the USB port, discharge and charge, you can monitor the working current and voltage of the device, and count the battery capacity.
A protective film is attached to the surface of the screen of the new machine, if you do not need to tear it off
Can be used as a daily simple test tool
1. It can detect the charging capacity of the battery of the tablet and mobile phone, and judge how much the battery performance is degraded and whether it needs to be replaced.
2. It can detect the discharge capacity of the power bank and calculate the conversion rate of the power bank.
3. Can detect the charging current of your digital devices.
4. 5V router and any other 5V USB port devices (such as USB lights) working current, etc.
Comes with usb input line, there is also a microusb port, you can use other lines for input. One end is connected to the power supply/mobile power supply. Note that the USB interface is used by default, that is, 5v; the other end is connected to the load, which can be a mobile phone.
