Recharging Charged Magic Items

The standard rules don’t allow item creation feats to recharge charged items such as wands. This is because wands are the most cost-effective form of expendable spellcasting in the game (the minimum price is 15 gp per charge, as compared to a minimum price of 25 gp per use for a scroll or 50 gp per use for a potion). Allowing wand recharging devalues scrolls and potions in the game, especially as using a wand does not provoke attacks of opportunity. A wand‘s lower price increment would also mean that partially recharging the wand is easily done with a short downtime period (10 charges per day for a 2nd-level wand, 4 per day for a 3rd-level wand, and 2 per day for a 4th-level wand), making the wand even more useful and cost-effective.

A GM who wants to allow wand recharging can require a minimum of 25 charges added to the item to help offset this advantage, as it forces you to spend a larger amount of gold at once instead of smaller amounts more frequently.
