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 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.

Works great to charge my phone quickly

Works great, quality feels very solid, the LED display is neat.

Seems to work great but finding a proper wall adapter with over 100watts was harder to find with etl or ulc approvals.
