I'm going to travel soon, where the access to the electric grid can be spotty and I don't want to put any additional strain on my iPad battery, by f.ex. charging a pencil - so, if I charge the pencil 100% before leaving, how long can the charge hold without using? Can I like charge it fully, then not use it for 2 weeks while travelling and then still be able to use it after the two weeks without re-charging? In other words how long does it take for a pencil to discharge on its own without use?
 
Depends on how much it is moving. I find it doesn't drain at all when it sits on my desk for periods of time, but in my backpack, it drains per day around 15%-20%.

For the purposes of a trip, I wouldn't worry about the effects of 1-2 charges via the iPad. There are people I know using Apple Pencils that they have charged via their iPad (only) for years.
 
It would only be a concern if you expect the iPad to also last two weeks without recharging. If you can charge the iPad you can charge the pencil.

If you’re moving a lot, it won’t hold a charge very well.
