Garmin 76csx and 9v USB power

[chuckr30]

I have a Garmin 76csx. If I get this battery powered USB port (https://www.electroids.com/main.php?content=store), is the Garmin voltage regulated at the USB port, or is just the circle port in the back regulated? I would like to use this gadget as a battery backup for my Garmin in the field.

 

Thanks.

I dont think I would want to risk it on a $450 76CSx. I keep 6 spare AAs in my carying case and I keep it plugged into my cigarette lighter when I am in my pickup.

What is the advantage of that when your unit uses standard AA batteries? Just carry extras of those.
