Insert the XTAR VI01 into a USB outlet to get a digital readout measuring the output voltage and output current from the USB output of a power source such as a powerbank or laptop.
The VI01 is useful in measuring the remaining power of a powerbank, or determining which USB powered device is drawing the most energy from a laptop’s battery. This knowledge can help a user determine the best way to conserve laptop battery power when on the move.
How to use the VI01:
- Insert the VI01 USB end (marked ‘IN’) into the USB port of the power source. VI01 will display the output voltage and output current at no load.
- Connect a USB powered device to the VI01’s USB port (marked ‘OUT’). VI01 will display the output voltage and output current with load.
- Sensitivity ±0.02V, ±0.02A
- Working voltage: 4.5-6.0V
- Test current: 0-2.5A
