It sounds like a great kit! You may want to consider a few simple changes:

1) I'd laminate the photocopies of documents. If they get wet they may be useless.

2) While I like the idea of using the same type of battery for all of your devices, I don't think that you've stored enough. I counted the number of batteries that you needed and came up with 13. You seem to be storing only sixteen. I'd double the number of batteries. You may want to consider using rechargables with a solar powered battery recharger.

3) You didn't specify how many people were going to use your kit, So I really can't judge if the food items are sufficient.

Good luck! I wish my kit was as well stocked as yours.
