How to: Change the fuse

Besides changing the light bulb, a real man (and woman) ought to know how to change a blown fuse. A fuse is a protective device that cuts off the current if a circuit overloads or if there is a fault. The fuse "blows" when the current carried exceeds the rated value for an excessive time. Here's a video on how to change the fuse of a PowerCube when it "blows".


I need to change the fuse for PowerCube Rewire USB. What is the spec on the fuse?

What is the spec on the fuse? I know it’s 5mm x 20mm, but is it fast-blow or slow-blow?
Thank you.
