We have rides sometimes which are whole day long and guys have Garmins which die out. I came across a few products that might help

Tried a search here but did not come up with anything. Any idea about how good these would be? What do you guys do for long rides? Can you charge the Garmins from say a pack like this while its being used on a ride?

The 205/305 should last at least 10 hours on a single charge. The 605/705 lasts about 15. I've used the 305 in the past with a cell phone battery booster like the ones you linked to.

I had a 15 hr ride in July and used a cheap usb battery booster I found at target. These things can be found just about anywhere.

Thanks guys.

Just another question. Did you guys ride with the charger plugged in or did you charge the Garmin during breaks?

UMD,

I know its supposed to last 10 hours, but does it really? And I would hate to lose data on my longest ride :-)

Got two of the Duracell USB chargers at Cosco (came two to the pack). It does charge the Garmin 705, but it only works with alkaline batteries - - won't work at all with NMH rechargables batteries - - bummer.

My longest ride this year was 12 hours. My 705 showed about a third of the battery left at the end of the ride.

I did both. At one break I forgot to plug it in. So I plugged it in and threw both my garmin and the charger in a jersey pocket. My garmin is able to keep a signal while in said pocket.

Glad to see this thread. I have recently started using my 705 for backcountry stuff and it works fine. Biggest issue is lack of replaceable batteries for multi-day trips (and limit of 100 waypoints). I am going to try it next time I go out for a few days, but the way this season is going, that is likely to be next year.

Longest ride on my 305 was 8 1/2 hours - no problem. On long rides I switch over to "smart" record mode b/c of storage limitations. I don't need all those detailed data points to tell thatI'm slow!

I got one of the Energizer chargers from my 305 when I was going on RAGBRAI for a week this year. I may be missing something, but I found that the plug from the charger wouldn't fit while the Garmin was mounted on the bike. That said, my Garmin never died during the day, and I used the Energizer to charge it at night.

Another issue worth mentioning if you're on a multi-day event - the Garmin has a limited capacity for data storage. I was riding for seven days with no opportunity to upload data. At the end, I had the basic mileage and time info for the whole week, but the detail information on elevation, cadence, etc., etc., was lost from the first 2 1/2 days.

Just do each day as an individual ride, have a card installed, and "save to card."

I assume you have a 705. The Edge 305 cannot use memory cards.

umd

It is supposed to last a lot longer than 10 hours, but about 10 hours was usually what I got. The 705 can go all day without any issues and there are no [practical] storage limitations either.

dark13star

Yes, sorry about that.

15 hours with a 705 was no problem on a long one day ride.

for my 305 I've used one of those cheap 4-AA USB chargers (connected up while riding) - works really well, as it depletes the AA batteries before it starts to draw down the battery in the 305. If you are doing much more than 130 miles or so you need aux power for the 305.

I've yet to find a long enough ride to really challenge my 705. I find I can get in a couple of good long rides before the battery starts to get low.

When I do week long rides, I try and charge it a couple of times overnight when I can find a plug.
