I like to ride brevets a style of long-distance cycling that involves riding 200k, 300k, 400k, 600k, and longer rides. The battery in my Garmin Edge 705 is two years old and currently has a run time of about 16 hours. This will get me through a 200k or a 300k, but not the longer rides. I've been looking for an external power supply since I bought the Garmin and recently a rider on a 600k brevet I was hosting showed me the Gomadic.

It is rare that a company makes a product that does exactly what you need, exceeds your expectations, costs less that you expect, and delivers it quicker than you would expect possible. Gomadic did all these things.

I ordered it on Monday morning, I received a shipment email on Monday afternoon, and the product was on my doorstep when I got home from work on Wednesday. It's very simple a battery case to hold four AA batteries, some electronics, an on-off switch, and a green power led.

On Saturday morning I put new Duracell batteries in and connected it to my Garmin. The backlight came on which is standard for the Garmin Edge so I set the illumination level to the lowest setting (other than off) and started my ride for the day. Then I finished the ride with the external battery pack still powering the Garmin, then I left it on all evening, all night, all the next day. It's still powering the Garmin over 44 hours later on the same set of batteries. I don't know when the batteries will run out. I would have been satisfied with eight hours of run time.

You should also note that, unlike when you charge from a computer or a wall socket, the Garmin will continue to operate when connected to this external power supply.

Sometimes a product is perfect. This is one of those times. If you own a Garmin Edge and need an external power supply, this is the product for you.
