There are two different types of Repair Kits, the standard ones used to repair armor, which can be found anywhere, and those used in the Alliance War. All repair kits are single-use.
Armor Repair Kits
These can be used to repair damage received in combat. Each Repair Kit has a level, which means that any items up to a certain level will be 100% repaired with one Kit. Items above that level will receive a smaller amount of repair, requiring multiple kits to fully repair. Standard kits can be purchased from Merchants. Crown Repair Kits can only be purchased from the Crown Store, but will fully repair all of your equipped armor, regardless of level.
