I have one of those in the box but after finding out that they do not put out a constant 5V and can go as high as 6V, its still in the package.
Thanks for that. For that reason, I have chosen not to buy it and take a chance on frying my $350 investment in the Edge. I still don't understand why Garmin won't either make one or offer one that is approved to work with the Edge. I've emailed them twice about this with no response.
Have you ever looked into some of the lithium cell phone charging units?
