Here are two gear suggestions for touring, based on our experience using them on the Transam. I have no affiliation with either product.
Handlebar bag: Koki Mini Dilly. Cost: ~$45. Small enough to minimize weight and wind resistance. Big enough to hold the essentials: smart phone, slim wallet, Baby Ruth or O'Henry, packable mini REI shopping bag, and Chapstick. Fits most handlebar/shifter combinations. Easy to access from the bike, even while riding (not recommended, you understand). Pops off easily to carry into a market or brew pub without looking out of place. And the fitted covers keep essentials dry when it rains. Unless you're carrying a large camera, you don't want a bigger handlebar bag. Gentlemen: The Mini Dilly could be mistaken for a small purse; but you're secure in your maleness, right?
Portable iphone charger: Mophie Juice Pack Powerstation Pro. Cost: ~$100. About the size of two iphone 4's stacked together. Will fully charge an iphone four times before it needs recharging (overnight) itself. My sister sent it to us unsolicited a few days before we left, and man, are we happy she did. We've found it adequate to keep the iphones of two camping cyclists charged continuously on the road (though we are careful with battery use, often using airplane mode). Much better than struggling with a solar charger. Read reviews online for more information.
