Garmin Edge 800, will it work...
« on: December 23, 2011, 05:11:43 pm »
Hi all,
I really like the Edge 800. The HR, Cadence, and that cool riding partner are what puts this over something like the eTrex 20. I'm riding the NTR starting in May. The issue that I see may be a deal killer is the internal battery and combined speed/cadence sensor. First can anyone tell me how fast it will recharge after a full day discharge? And how is it charged? Next is that sensor, I'll be riding a Trident recumbent trike so the crank does not overlap the rear tire to allow a combined sensor. Anyone know if the functions can use separate sensors?
Any other big issues?
The main reason I do like this unit is it can double for training for an Triathlon later(not on the trike naturally:).
Thanks
Ed

The owner's manual p. 47 says it is charged through its mini-USB connector, either from a computer or from an AC adapter. It does not mention the size or weight of the AC adapter. This review says charging time is "up to 2 hours."

Before buying, I suggest you look at the many opinions about the Edge series in this forum. Go back to the GPS Discussion page that lists the topics and run a search for Edge. An excellent device for training, it is not the best for touring new terrain.

Hi Fred, Thanks for that info and the Garmin FAQ says 4-5 hours using their External Power Pack.
Yes I have read many of the Edge related posts, like I said my main issues are this charging time and cost compared to a couple AA batteries.  I'm trying to envision getting to that unimproved evening camp site and how I get my "entertainment system" :), as someone called, recharged. I'm probably going the route of a eTrex or something else that has AA or AAA batteries.

For charging on the go, think about:

- AA battery chargers. For example:

- Solar power chargers

- Multi-option pack
http://www.rei.com/product/825373/garmin-external-battery-pack
http://www.rei.com/product/827121/goal-zero-guide-10-plus-adventure-kit-solar-charger

They all provide USB output that you can connect to the GPS unit, phone, and others.

I have the Edge 705 for the same exact reason that I use it all year around when training and riding. I use it on bicycle tours and backpacking trips with mobile chargers, that I can use with my iPhone as well.

Smart move.  The Edge series are best considered as smart cycle computers, excellent for training. They can be used for long rides into unfamiliar terrain, with some difficulty as you have seen here, but the eTrex and GPSmap series work better for long tours, IMO.
