If you have 1 charge left and you buy a new 20 charge merchant or 10 charge vault npc, it will go on the old item. If you use it then, the item is gone and you lose all your new bought stacks.
Somebody already posted the same thing shortly with Stealth Lore. This applies to basically every stackable charge items.
