I often carry a small iPad, and I don't have too much of a problem keeping it charged. I also don't use it as often on a trip as I do at home. I have used a dynamo hub and a solar panel to keep a battery charged, and that battery has been sufficient to recharge my phone and tablet every night. On my most recent trip, I didn't charge with the dynamo, only solar, with a 20,000 mAh battery. Weather was lousy and the solar panel didn't provide a whole lot of extra power, but I did go for about a 5 day stretch without plugging in. With a dynamo solution I might have gone indefinitely. Tablets use a lot less power than laptops, in my experience, and you may find, as I did, that you use it a lot less than you think you will when touring.
