I have already owned a usb tester. Do I still find this cable useful? Definately! There are two advantages of this cable over the USB tester: 1. It will plug into any usb port without worrying about narrow space or mobile case blocking. 2. It is much convinient to use this cable than using a usb cable + a usb tester. I do not use this cable as main charging cable because I have other cables for that purpose. I only want to use it to test wattage output. I hope this cable will last for very long time because of that.

This is a totally unnecessary item but I absolutely love it, there is something very satisfying about knowing how much juice you are pulling from the wall. One thing to note is that if you plug this into the left-hand side of your MacBook the display is upside down, a minor inconvenience if that is your usual charging side.

I bought two cables and both died within a year. They either won't charge or will charge only at very precise angle into my phone or laptop. I think one actually fried my Lenovo laptop.
