no you cant, thats gonna be ~60mA of DC across your body provided you have open flesh wounds on both hands :) painful yes, but not deadly

- CamperBob2 12y ago60 mA is a big deal, as it's getting into the current levels that are more likely to cause fibrillation (at least for AC). But the only way 20V will push that much current through your body is through open wounds. In a worst case scenario, yes, 20V could electrocute a person. More likely, though, a crappy USB cable carrying 5A will kill people by burning their house down.
- e12e 12y agoSome interesting points on "low" voltage and wounds here. I wonder about child proofing (and, as you say, fireproofing!). Will most people regard these as "100 watt dangerous" or "peripheral/signal-cable safe"? Frankly, I'm worried enough about the possibility of fire due to power over ethernet (eg: hotel wifi). All that said, modern, useful, standardised dc cabling does sound convenient.

- ars 12y agoYou are wrong. 20v below the skin will kill. And if this story is to be believed 9v has in fact killed: http://darwinawards.com/darwin/darwin1999-50.html http://darwinawards.com/darwin/darwin1999-50.html
- Gurkenmaster 12y ago9v is not that far away from the usual 5v of a USB charger and some tablets charge with 2A.
- rasz_pl 12y agoNice, anecdote from a funny book against established safety literature.
