This Is Significant!

I have read of many concerns regarding Garmin Edge 305 relative short battery life [Garmin battery specifications: 800 mAh rechargeable lithium-ion battery; 12 hours typical use] as it relates to so called ultra events. That is any activity where you need the device beyond its running capacity determined by charge you begin the event with. Note, the use of the speed/cadence sensor, heart monitor, GPS, backlight, etc. deplete the battery at a faster rate. I use both the speed/cadence sensor and heart rate monitor.

To meet this challenge, I am using a Socket Mobile Power Pack purchased from Comalco. In its leather case the dimensions are 4.5 x 3.4 x 1.4 inches or 114.3 x 86.4 x 35.6 millimeters and it weighs 13 ozs. or 360 kgs. I found Internet prices range from $149 to $89 [US Dollars]. I did not find the $89 price when I purchased mine]. Some will say the Socket Power Pack is pricey, although I purchased mine for $93 [the lowest price I found at the time] from Comalco. This price is reasonable for me, considering other options discussed below, the pack’s reliability, and the ability to use my Garmin for extended periods. In addition to providing power for my Edge, the power pack can be used to charge other 5 or 6 volt devices such as my cell phone, iPod, etc.

Here are user experiences, as written in threads at BROL Forums:

You get the idea.

Many solutions have been adopted. Some use 4 AA batteries to feed the Edge’s USB port and others use home-brewed devices to answer the call. In my mind, I wanted, and found, a lithium-ion device that will give me days of continuous GPS running. In use, at the end of the cycling day, I will turn off my GPS. The Socket Mobile Power Pack meets my needs, and exceeds my expectations.

In reality, with this setup, the Edge never goes to its internal battery. So, I have a 5-8 hr. reserve, should my power pack battery be depleted or fail. Of course, the Socket can be charged [replenished] overnight [if you have access to AC], then I’m back with full potential. I cannot think of a circumstance where this combination will not meet my Edge battery requirements.

So far, the Garmin has run uninterrupted [not turned off] for ~60 hours before the yellow LED on the power pack began to flash indicating it low battery state. If not charged at this point, the power pack will shut down. Also, when the power pack went to a low battery state, the Edge 305 began to use its battery. So, the GPS is still running, and should for at least 5-8 hours.

My judgment is this combination will keep me with a working 305 throughout my tour, especially with me turning if off at the end of the day. Other users my want to consider this option.


IT’s HERE!!!

My RANS Stratus XP arrived this afternoon, 5/10/2006, at 12:15 p.m. EDT. [Thanks Dana!]

  • It weighs 34 lbs (15.4 kgs), and;
  • Is 92.5 inches (234.6 cms) long

~ My new baby ~

Now for setup. Regretably, I have much to do in the office this afternoon and cannot dedicate the complete day to the Stratus.

At this point, I’m now waiting on the following:

The item from Angletech & the Crank Brothers pedals from Spin Cyclz.

Today, I reassembled the bike and did lots of test riding.

This cycle is really COOL! Now I have 2 fun-to-ride recumbents. This tour will be great of my Stratus XP.

Back to installing stuff–pictures soon…

Fayetteville 2 Key West Tour Logistics

Recording: I will capture the route using a Garmin Edge 305 and post it to MotionBased Web Site as we travel along. In addition, I hope to maintain this blog as a travel log of sorts. Depending on weight, I plan to carry one or more cameras.

Travel: We plan to depart Wednesday, June 7, 2006, and return Saturday, June 17, 2006, at 7:15 a.m., or possibly Sunday. At this time, we are discussing return via Amtrak. My rate as a Veteran was $53.70 [now $69.70–I should have made my reservations at the lower price] for a coach seat and a 16 hour, 44 minute ride back to Fayetteville, arriving ~11:59 p.m. 6/17/2006. Reservations made.

Amtrak makes provisions for bicycle transport.

Consider this for your biking.
