I LIKE IT! October 4, 2018
By: Ike from Ogdensburg, NY United States  
This little device lets you monitor the power usage of whatever  device you attach via your USB port.  Whether powered from your computer, your car, a mains adapter, or whatever source you may have concocted, this little device is there with answers.  The only thing I'd change is adding a switch to let users select volts, amps, or alternating as suits their objectives, rather than always alternating..
