Now that I am thinking about it, I guess I am going to have same problems with tablet or laptop. With smartphone, I can use the battery bank and dynamo hub to always keep it charged. I didn't think completely through my power options/problems when it comes to charging the laptop or tablet. I need to spend more time thinking this through and see what other folks say they do.
Research charging from a dyno hub and you will find that most people charge directly to a battery and use that to charge devices. Not the most efficient method, but with variable speeds, phones especially, can stop charging at a low speed and not start charging again at higher speeds.
Obviously your speed makes a difference to your charging ability. Slow days can mean no power.
You could supplement a dynohub with a solar panel to use around camp, or when you stop. Again, different panels have different characteristics.
You really need to sit down and estimate your daily usage. then work out if that is possible given speed, distances, converter efficiency and losses during charging.
I have gone 3 weeks, totally power independent, using a dynohub and 2 powerbanks (10K & 5k), powering a phone, kindle, tablet, Wahoo Elemnt, i-pod (hardly used) & battery charging. But I hardly use my phone on tour, similar with the tablet.
Earlier this year I investigated the option of a laptop/chromebook.
I decided against it on the basis that I could not justify the price nor size of a powerbank to power it. Plugging it in somewhere does not suit my style of touring. Instead a new Android tablet with a bluetooth keyboard is as good - for me.
