Re: Garmin on board charger question/400K Hopland

[Willie Hunt]

The simple way to keep your GPS powered up for ultra rides is to plug it into an external USB power source.  There are many available, such as these:

Chris,

The new twist on this question (which as asked before) is the Garmin 510 vs Garmin 500. One of the biggest problems I have with the Garmin 500 is the inability to charge the Garmin with most off the shelf USB chargers. The Garmin simply shuts off while charging. Sometimes it even does a reset and you end up with two .fit files for the same ride (The data is saved just not as one ride)

As I said MOST chargers, I found out from the Garmin forums you need a USB cable with a specific resistance between one of the pins and ground, Most chargers do not have this resistance. A few do. The one I use is the GoMadic portable power pack, $20 on Amazon, takes 4xAAs:

http://www.amazon.com/gp/product/B0041L0NG0/ref=oh_details_o05_s00_i00?ie=UTF8&psc=1

There are other options. Here was another thread on this group about the 500

https://groups.google.com/forum/?fromgroups=#!searchin/sfrandon/Garmin/sfrandon/6QMvIWf5JFA/QG8FHg8YU4sJ

You have the 510, so it might not shut off while charging. You should check this out before deciding what unit to buy.

As far as mounting options, I zip tie to the GoMadic to stem (I have a longer stem), then route the cable to the back of a after market Garmin mount. 

Another option which I tried on the 400 was to charge the Garmin in the controls. Turns out I didn't charge enough and missed out on the last 10 miles (I was in FairFax).

There are also rechargeable USB style batteries.  I used one at PBP in 2011.  Despite running my 705 with the backlight on, it was still fully charged after running for 65+ hours.  I turned everything off when I was sleeping.  

Depending on how the external charger's port or how the cable connecting to the Garmin is configured, you can sometimes have issues with the Garmin thinking it's attached to a computer and shutting itself down.  The D+ and D- pins need to be shorted together so the Garmin knows it's looking at a power source.  Most cables don't do this.  

Craig

[Sarah Burke]

I use the Power monkey charger which solves the problem John identified (the Garmin shutting off while charging):  http://www.probikekit.com/bicycle-computers-gps-hrm/garmin-external-battery-pack/10771916.html?utm_source=google&utm_medium=base&utm_campaign=google_base_usd 

Works great - and it also charged my 2 hour run light one year at DMD.

Sarah

[Willie Hunt]

Yes, many USB devices need either the data pins shorted, or termination resistors of some sort to charge.  The Garmin 800 (only bike GPS I have) does not care at all.  I built my own 5 volt power sources wired to USB cables and left the data lines open.  The Garmin 800, lights up when the USB power is connected, operates normally and charges the internal battery if it is drained down.  It does have some funky business with the auto start feature when it connected to external power, so I disabled that and I just leave the time running through all stops, unless I'm going to reset and save that part of the ride.  Also, I have run into the "white screen of death" on the DMD, because I tried to log the whole ride into one file.  I've heard it has about an 18 hour limit on recording data into one file.

Willie

[Roland Bevan]

Shortly after I got my Garmin 800 I had that problem with my Garmin 800 hanging on a couple of long rides over 24 hours (600k), so I normally break up the longer rides into multiple parts separated by my sleep break. I haven't noticed any issues in a couple of years - I have recorded several rides over 20 hours (400ks, Flèche) and the 30.5 hour first "day" of the Big Wild Ride 1200k in 2011 recorded with no problems. Make sure your 800 firmware is up to date. It may also make a difference whether you're recording to the internal memory or to an SD card, and how full that location is. I have mine recording to internal memory and make sure to clear out old activities and routes every so often; not sure if this helps but it sure can't hurt.

This topic was discussed here last year: http://groups.google.com/group/sfrandon/browse_thread/thread/e9032f2167f92450/e2d2e6f222a51d01

I do always carry two copies of the cue sheet, the GPS is nice but it is just another thing that can go wrong. 

However my GlobalSat GS-580P (Same thing as the Timex Cycle Trainer) does charge while riding with *any* regular USB cable and power source. One great feature the GS-580P has is you can upload a route to it and it will show on the device as a thick line (no background map but very usable for randonnuering) and a thiner solid line with an arrow at the end that is where you are and it will show how far and the direction to the next turn. If the file you uploaded has speed, the device will show you how far ahead or behind you are in comparison to the file. I think for $170 (shipped) with HR monitor, cadence and speed sensors included is the best deal for a Randonneuring friendly GPS right now. Highly recommend if you can live with their windows-only software, not a deal breaker for me as I have Parallels installed in my macs at home. I think the Timex is Mac friendly but then you pay more for it.

Me, too -- one copy at hand (in sheet viewer or stuffed in easy-access
pocket) and another little copy all folded up in my wallet!

Meanwhile, I started using a new bike for rando rides as of December,
and still have not yet mounted a cyclocomputer nor my heartrate
monitor. Why am I not missing them?

I should confess, however, that I now have a smartphone, and have
started loading the .gpx tracks into an app that can pre-load map
tiles for offline viewing. I have peeked at that to be reassured via
GPS that I'm on the course. I have also peeked at Strava to see
elapsed mileage during a ride.

So, far from gadget-free, but, until December, my habit was to pretty
much continuously watch mileage, clock, and heartrate as I rode. It's
kind of nice not to be doing that for a change.

-Greg

[Peg Miller]

I agree with Sarah Burke. I was having the same problems until I
bought the Power Monkey. Just spend the money and buy one. It is
well worth the $80.00. Nice call Sarah.

I've used the Energizer Energi-to-Go for years but recently moved to a MiLi since it's even smaller than the E-to-G.  A lot of folks use the GoMadic chargers but they're too long for my Bento Box.

MiLi:
$30.00: http://www.amazon.com/MiLi-Crystal-External-Blackberry-Motorola/dp/B003TO56P8/

Energi-to-Go
$45.00: http://www.amazon.com/Energizer-XP2000-Universal-Rechargeable-Power/dp/B0029U2WWI/

If you own an Edge 500 or 510 and want to charge it on the bike, buy one of these:

http://www.amazon.com/Garmin-010-11251-15-Out-Front-Bike-Mount/dp/B0096855IO/

This is due to the location of the charging receptacle on the 500 being on the bottom of the device unlike the 800 or 810 on the rear of the GPS.

The retractable cord in this travel kit works great:

Ahh -- yes, indeed! Not your precise numbers, as mine are really
different, but the notion of not going too hard. After years of
watching my HRM, I've kind of hard-wired myself to monitor my effort
level. Agreed, very important!

Yep, a Shutter Precision generator hub powering a Luxos "U" headlamp
with integrated USB charger powering the iPhone running Strava for the
whole 400km. I ran the light 100% of the trip, including daytime, but
I did unplug the phone for the nighttime descents for max 90lux light
output.

Hi Chris,

I recently purchased a Garmin 500, after the GPS app on my Android phone locked up during the 300k ride and I didn't record the whole track.  On the 400k I used a Minty Boost to charge my GPS and it worked well.  It seems the Garmin 500 will NOT stay on when charging, though, so I charged it once at the Guernville control (which bumped it up to ~75% charge) then again at the Petaluma control (bumped it up to ~ 55% charge) and made it to the finish with plenty of juice to spare (I turned the GPS on at about 04:40 Saturday and off at about 03:40 Sunday).  I ended up with 3 .fit files on the GPS, which is fine with me because it is easy to combine the files together using the open source gpsbabel tool to merge the three files together into one gpx file.  I uploaded the gpx file to ridewithgps.com; you can see that track here.  I think this setup will work well for me on longer rides, too.

Hoping that helps,

Eric.

I find the heartrate monitor works great for keeping me patient. I know
that I can't ever go over 160bpm or I'm gonna have a bad day, and I
should try to keep it in the 120s/130s unless I'm pulling into wind.

I was expecting the 400 to be my stopping point this season, but I think
I'll try the 600 after the comfortable finish this weekend.

Three credits:
- Sandwiches, sandwiches, sandwiches. Energy stuff makes me nauseous
after a while.
- Riding with strong, experienced riders as much as possible.
- Keeping the HR down.

And to get back on topic, I boosted my Garmin Edge 500 a couple of times
with the battery pack out of my voltaic solar panel. It chopped the ride
into 3, and made mileage a bit more annoying on the cue sheet, but I
combined the GPXs afterwards and all was well. I'll be upgrading to one
of the aforementioned chargers before the 600! Thanks for the tips,
everyone.

To throw more fuel on the fire, I use this one with my Garmin 800. As an added bonus it has a built-in flashlight feature, which may be handy on those dark and stormy nights. I don't use the cords that came with it as one is a bit too long and the other is too short, but the 800 doesn't seem to care what you use to charge it with so that doesn't matter. This will power my Garmin 800 for well over 24 hours straight.  On longer rides I recharge it during my sleep break.

Cue sheets never need recharging, however. Review the course ahead of time and carry a cue sheet. If your GPS dies, ride on!

Of course I am watching this thread, and while I don't think I'll pop for another one, I'm still a bit unsure...

The Iphone apps are almost as good and they have faster upload speeds, which can be used to get ya down the road. Only problem with them is there isn't cell phone reception everywhere... but almost.

In my mind, you need it precisely because you can't access FB from it. :-) When riding an unfamiliar route far away from home, load up the file and follow the purple line to the next control. I use tcx files from RideWithGPS and get turn-by-turn prompts for the actual route and off-course warnings when I deviate, while the Garmin is prevented from creating its own fanciful route.

Smartphones are handy, keep one in your bag. In airplane mode. Otherwise they are big, bulky, power-hungry, and don't like the rain. And the further "out there" you get, the less likely you are to have a data connection, just when you need it most.

Still, I have a head for routes and most of the time on local rides I'm using the Garmin as a fancy recording bike computer. ;-)

There is a huge variety of external USB batteries available. That will charge phones, garmins and even tablets. The key to charging and using your Garmin at the same time is having the correct cable because the wrong one will attempt to connect data and may turn off your Garmin computers while charging as previously discussed last year on this thread

I use an iPhone app (Gaia) that cachsd map tiles & .gpx routes so that
I can navigate offline just fine. All I need to do is pre-load the
nap tiles at home before I ride, and then just a GPS satellite signal
does the trick.

I use it in the east bay hills on the trails all the time, and also

And viewing it the other way, Garmins never get soggy from sweat and fall apart, nor do they blow away while trying to flip the thing over while riding. If your cue sheet becomes lost or unreadable, ride on! Best to have both for sure. They both have their advantages and disadvantages, certainly.

The Gomadic has replaceable plugs (look like stereo headphone plug). As long as you have the one for your phone it should be able to charge it. Check out the Gomadic web page.

You may want to check if you need a Gomadic. The only reason I like them for the 500 is that the cable has the proper resistor in place to allow the 500 to charge and be used at the same time. This is something that appears to be unique to the 500. Most other Garmin devices don't require a special cable. Check yours out, try turning the 800 on, getting GPS signal then plug it into a wall wort using a cable. If it doesn't stop recording data and charges then you most likely don't need the special cable. In that case any of the commercially available portable USB chargers that can be purchased at Target, Radio Shack etc...

All,

I am starting to plan a route for the Dart Populaire. One option is to start in Noe Valley and head south toward Woodside and then over to the East Bay via Dumbarton Bridge.

Does anyone have suggestions for a route to get from 24th Street BART to Crystal Springs Reservoir and then on to Woodside?

Thanks.

if you search strava for skyline you'll probably find numerous variants.

if you want some extra distance and climbing, drop from skyline down in to pacifica and ride PCH to Tunitas or something: http://sf2g.com/hmbw.html , also search strava for variants.

Another interesting option if you have not already seen it.

Randos,

I think this is my first post to the group. I bought the Garmin 510 thinking I would be set. Then I learned that .gpx/.tcx stuff matters. Then I rode on the Mountain House segment with John and learned that you have to convert to .fit format for turn-by-turn...Oy vey!

But worse, I bought the new, hot Garmin item b/c it says 20 hours battery life...like they don't factor in the fact that people might be riding in the dark or what? It failed at mile 209 and I arrived pre-20 hours!?

Point being...besides stating that Hopland was a fantastic adventure (and after Googling), QUESTION: how would one suggest how to affordably keep a charge on a Garmin 510 for something that might require at least 40 hours? I think a trickle charge type solution is needed, but the Google results are very focused on iPhone charger stuff. (iStuff, that's another conversation)

I was impressed with a colleague's dynamo solution, but I don't want to build a new wheel for a charging solution (yet!).

There must be a simple rechargeable pack to mount on one of the frames or bars - but unless cycling is mentioned, it gets funky - like not the extreme stuff required...my Google and Amazon searches did not deliver.

I might add that when the Garmin failed, fellow Randos were more or less nearby to follow...

thanks for passing it on!

And thank you for any Garmin charger advice (unless there is some uber archive on this topic that I am not aware of.)

Sincerely,
