Hello Doug.
Thank you for your detailed feedback.
The reason why our devices run on 12 volt is that the the 12V vehicle battery right there where you are working.
It is our view that most of our customers prefer simply clipping onto the battery over having to reach for the nearest outlet, use an extension cord, and having to acquire a regulated and inverted 240v AC/12V DC supply, to use our product.
It is for these same reasons that you typically find other automotive workshop tools such as strobe lights, also running on 12 V.
We believe that our website clearly specifies the operating voltage and it shows a picture of the alligator clamps on the product page, but we will be taking your comments into account for the next update.
Again thank for your business and taking the time to provide your feedback!
Regards,
Ray
