If you are staying in paid for accommodation (hotel/hostel/B&B) there's no problem. A smallish powerbank, in case you run short during the day will do.
If you are camping, it's more involved.
If you rely on mains electricity, it's worth going for a larger powerbank with quick charge and/or a multi-port USB plug, so you can maximise the gain if you find a cafe with a socket. Campsite reception means you can't leave until it's reopoened in the morning, that you don't have access after they've closed in the evening. Shower block are theft prone, and may not have anything other than above-washbasin shaver sockets anyway. Electric hookups cost, and mean carrying a fairly builky adapter.
Solar means a fairly large panel if it's to be successful - A4-size, folded, with a 15-20W rating. Quite aside from clouds and shade, having the panel on the back of the bike means it's not pointing at the sun a lot of the time, and in the evening the sun is often too low for good charging.
Dynamos are reliable/forecastable, but the power rating is quite low, and if you are in a mountainous area and spend a lot of time riding slowly uphill, you may find that generation doesn't keep up with usage, particularly if you have high requirements, like feeding a laptop or tablet.
It's simplest to reduce your power requirements as much as possible.
That might mean an e-ink kindle rather than a tablet, or navigating using an AA-powered Garmin rather than a phone.
Alternatively, you could go old-school and learn how to read a paper map (as available in shops along the route).
I use a an e-ink kindle and an AA-powered Garmin, and find that a 10Ah dynamo-charged powerbank with occasional mains top up is sufficient
