Name: ATM7: 1 x Online chunk loader
Price: 4.99 AUD

Personal chunk loaders keep a single chunk loaded into memory, even when you're not standing in that particular chunk. To activate a loader, place an Iron Block inside the chunk you want to keep loaded, and right-click it with a Blaze Rod.

These can be hugely beneficial when you want to spread your base out further than a few chunks, but also want machines to keep running when you aren't close to them.

Note that these loaders do not remain active when you log off.
