Do you own a fan that needs more power? Well, that's where this 12 Volt cable comes in. Depending on your use case, extremely useful.

I was surprised at the quality of the cable. The wire gauges are thick and a stiff braided sleeve and heat shrink have been applied. They went the extra mile and put some adhesive where the heat shrink meets the stress relief to anchor the sleeve to the wires. It also has a 4-pin female connector so you can use PWM fans, and not just the 3-pin variety. This cable came coiled, not folded and twisty tied (I hate when they do that, cables take forever to straighten out). Even the resealable bag it came in was thick.

Does exactly what I needed — powered my PC fans from a USB port without a hitch. Clean, efficient, and well made!

As several other recent reviews have mentioned, this is not a 12V step up from 5V cable. It outputs 5V, it's a standard cable. Measured with a multimeter on output of 4.98V.
