I have always done it this way, it's only trickle charging and not drawing any current so it's not a problem. It's not like i am vaping while charging, i use usb for alsorts of things
It might be worth checking the draw of any and all devices you are plugging into usb ports on your puter. Most will conform to usb standards and will be rated at 500ma or less. However Most vape devices will attempt to draw significantly more power, This poses a SIGNIFICANT risk to your puter's usb circuitry which is probably embedded within the PC mainboard.
USB3 ports can supply more power and if fitted on your puter check your puters specs to see what the rating is probably 900ma? but even this is less than 1a so i would not use usb3 to power a 1a device either..
With DC power you want the more amps in the supply than the drw.
