Keep having the Edge 520 die on me on rides of over 10 hours in length.
Off on a 12-14hr ride this weekend and want a recommendation on the smallest portable charger on the market that i can tape to my stem.
Last week I tied my 1800mah pack to my stem which was ok but realistically I only need 500mah maximum for the 520 so don't want to carry unnecessary weight around with me on a 220km ride.
Lipstick sized seems to be the smallest one I can find, but they are still 2000mah +.
This tiny one looks ideal but doesn't seem to be available yet http://www.thegadgetcode.com/2013/03/worlds-smallest-portable-charger-handy.html
any tips?
