Durability Banks - can hold up to 500 charges. When held, every item will use them instead of their durability* - so, if you're holding a charged bank, your items won't break.
Chargers - can charge banks, using 1 lapis per 100 charges.
*golden items use up twice as much charges as other items.
Please note that this mod is in beta, so it might have some balance issues.
