InLine USB Smart Control, multimetro, monitoraggio ricarica

The InLine USB Smart Control Multimeter 66761 is a compact inline device for monitoring and protecting USB charging processes. It measures voltage and current, counts capacity (mAh), and provides selectable protection and status indicators. The cable length is 1 m; the unit is powered from 4.5–20 V and supports currents up to 2.5 A.

Advantages

The device combines overheating, overcurrent and overvoltage protection with a timer and a capacity counter in one unit. A push-button cycles through clear indicators for overall safety status, specific protection modes and the previous charge’s mAh. The built-in timer can automatically stop charging after a preset duration (2, 4, 6, 8, or 10 hours), simplifying safe charge management.

Suitable for

• Monitoring USB charging of smartphones and tablets
• Measuring voltage and current of USB-powered devices
• Counting charge capacity (mAh) during charging cycles
• Protecting devices from overheating, overcurrent and overvoltage

How to use

Connect the InLine USB Smart Control Multimeter between the USB power source and the device to be charged (USB A to Micro-USB B). Use the push-button to cycle through the display modes: overall safety status, overheating protection, overcurrent protection, overvoltage protection, capacity counter and previous charge mAh. To set an automatic stop time, select the timer and choose 2, 4, 6, 8 or 10 hours; the unit will terminate charging when the selected time elapses.

Recommendations

Use the device within specified voltage (4.5–20 V) and current (up to 2.5 A) limits and avoid exposing the cable and electronics to moisture or mechanical damage. Regularly check displayed values during charging to ensure safe operation.
