The Lapotron Loader Upgrade is an item from the Railcraft mod. This item is an upgrade for the Energy Loader and Energy Unloader. It will add 1,000,000 extra Energy Units storage to the loader that it is installed into. A maximum of nine can be installed into any loader; adding any more will do absolutely nothing. The Lapotron Loader Upgrade does not work in other machines, such as the ones from IndustrialCraft 2.
