DROK® LED Dual USB Digital Multimeter Voltage Current Capacity Power Meter
|DROK® LED Dual USB Digital Multimeter Voltage Current Capacity Power Meter|
A must have item if you want to know what’s happening with your phone battery
This is one of those devices that is priceless when you want or need to determine if your USB chargers and cables are working properly.
While the monitors read out is rather small it’s still bright enough to read even in a well-lit room. What it shows you provides all of the details you need to keep an eye on your batteries and chargers. By showing charger Voltage, Current, Charging Wattage, and Calculated Battery Capacity you can:
~Determine if your charger is putting out enough current, see if it matches what its rated at
~See if the voltage drops when the charger is putting out high current (Amps) which is a bad thing
While monitoring the two functions it still passes data and I found that it did not slow down the transfer speeds including USB 3.
Using this is as easy as plugging a USB cord into a charger and then the device. Simply plug the display into either USB port first and then plug the cable into the other end of the display. Now connect your phone or other device and that’s it.
I’ve tested it on several chargers and devices and found it to be accurate when compared to bench meters.
