Ideas for extending battery life on Garmin Edge 305 for a double century

[Brad Ford]

I'm preparing to ride a very hilly double (over 20,000 ft of
climbing), so I'm expecting it to be a long day in the saddle. 12+
hours. My Garmin Edge only gets 6+ hours. It has a little usb port
on it through which it can recharge. Does anyone know of any
lightweight solution to plug it into while on the latter 6 hours of
the slog? I'm thinking something small enough to fit in a Bento box
with a cord plugging into the garmin, which is on my stem. Please let
me know if you've seen any products that would fit the profile.

thx.

I bought an Eveready phone charger that uses two AA batteries and has a
mini-usb connector on the cable. It seems to charge the Garmin just fine.

I bought mine at Lowe's, but it available online. For example, see

The least of my worries if I were doing a double century (I did once)
would be GPS. Food is what you'll need my boy.

I built the minty boost kit, works great, I've used it when I forgot to
recharge.
