## Description

FNIRSI Usb Battery Tester Voltmeter Ammeter Type-C Fast Charge Detection Trigger Capacity Measurement Ripple Measurement, Multicolor : desertcart.in: Industrial & Scientific

Review: Best for price, better than impoprting. - Best for price, works as intented. Make sure to use input for input only, and same for output. Flickers a bit when undervolted. Firmware update make sit work more good. Bluetooth app by FNIRSI works only after GPS is turned on and pairs only via app. Its weird n unnecessary yet ok. Accuracy is fine maybe 1-2% vary.
Review: Awesome usb type c tool - I needed something to check the hardware side projects i create where I power then with type c decoys. This board helps me quickly diagnose and failures in design and is able to trigger output voltages for different type c spec level. The graph over time and stats feature is really useful and i am currently using this with the desktop app which is working flawlessly.
