EZ Power Supply Tester & USB Vacuum Review
Posted on by LSDsmurf
The USB vacuum couldn't be any easier to use. You plug it in, turn it on, and clean the dust. However there are two modes; the low-power and the high-power. When using the toggle switch to power on the vacuum the default is low power however underneath the led is a button which, when pushed and held, the vacuum switches to high power. This power.
