Run Garmin Oregon 450 off external power?
« on: May 28, 2013, 09:15:08 pm »
I recently got a "B & M Luxos U" dyno headlight (quite bright & a very wide beam, recommended!), which has a USB charging port (will charge devices in route, so it claims).  I have had a bit of success charging my smartphone, (first ride around the block, only 5 minute ride).  What I want to know is if I apply a USB charging current to the Oregon 450, will it switch to running off the external source and save the internal AA batteries?

You probably know the answer to this by now but... I have an Oregon 450 and use an external battery to run it.  The Oregon screen stays on.  The battery I have can be charged via USB.  I have just received my generator hub and a Bright-Bike Revolution charger.  I'll let you know how it works out, but I'm not expecting any problems.

It seems like it should. The manual recommends using an external power when operating the unit extensively, with a reference to Vehicle Power Cable "to power your Garmin device and conserve battery life."

The USB source should not be any different.
