USB 2.0 Power Monitor (Red) YZXstudio Voltage Current Meter High Resolution OLED

Product Description

USB 2.0 Power Monitor (Red) YZXstudio Voltage Current Meter High Resolution OLED

1. Improved button pushing response.
2. Now requires long pressing in the configuration menu items to prevent accidental modification to the settings.
3. Voltage and Current curves now displayed on the same screen.
4. New fast updating V/A curves, and a new D+/D- voltage curve.
5. Improved charger identification to show alternative possibility.
6. New “Offline Curves” feature to allow saving of the V/A curves into the device’s memory. Configurable between a 1 to 24-hour period, over 384 data points. This makes reviewing charge/discharge curves extremely convenient without needing to log the data remotely.
7. Qualcomm (QC) 3.0 compatible.
