Sure, if you use it with a power 2A USB power source, then you've got 10 watts. That's enough for a satisfying vape with most toppers. But plug it into a port that can only provide the standard 500 mA and let us know how well it works.
Yes I said, I use them all the time, and yes that means regular usb ports; I ALSO have a 2A adapter.
I don't know if the usb ports on my monitor are 500mA, I suspect it's more link 1A; the chargers are 420mA;
