Question: What is the length of the usb mini cable?
Document: This little product saves a lot of the extra work of powering a mini usb device. I used it for GPS power. I hooked it into the scooter's horn wiring so that when the ignition was on the GPS was powered automatically. My suggestion is to do this as opposed to a cigar lighter outlet on scooters where the front wiring is easily accessible. Simple device, simple install and great result.
Just what I needed to power up a GPS on a snowmobile, It works great. Mini USB power 5 volts
Then the GPS continues on it's own battery backup while It guarantee  my phone needs.
I had an older 12v - 5V USB on my 2004 and it failed due to moisture. This unit hooked right up where that was and does the job. My only issue is that the USB cord could be longer. running the cord up my handlebar to the mirror stalk where the GPS sits left the electronics box mounted barely under the trim next to the steering head.
Answer: About 5.5 - 6 inches I'm pretty sure
