     Well the device monitor is pretty much accurate for all devices I have tested. It's only used for testing propose, not for long run charging along with the charging device as this mini monitor get heated up if  current is1A or above 1A.  (Heating for long time will definitely reduce its life or melt down it's solder as there are no heat sinks for long run propose). For this price this is the ultimate testing mini monitor.Hope sooner we will find industrialists manufacturing for India manufacturing these types of devices.

    Very Useful
  

*by P***R on Reviewed in India on 8 March 2019*

This is very handy way of finding out how much safe the charger voltage is and how much current the phone or tablet is drawing from the charger. First 2 units were OK. In next 2 units, the connection was a bit of challenge. If I insert the USB charger cable's A type connector in this module then it would go fully well inside but the current drawn was zero. If I pull it out a little bit then it would start drawing current.You can see how the charging current reduces with time as the battery gets charged and that  gives you some indication that battery is in good health.I use it for testing or measuring current drawn by Arduino & other micro controller boards, under different operating conditions.

    Not for Qualcomm QC Chargers.
  

*by K***N on Reviewed in India on 13 March 2020*

Doesn't work as expected for me as its voltage capability for Qualcomm Quick/Fast Chargers is capped at 7.5V. As a result my 9V/2A output is reading as 7.5V/2A even though fast charge is working. You need to throw a wild guess when you see 7.5V that device is working.Apart from that 5V output is reading okay.
