The Advanced Lappack is an armor item added by GraviSuite. It is an upgraded version of the LapPack. When worn in the chest armor slot, it stores 1 million EU, and charges the electric tools in your hotbar. This 1 million EU storage is over three times the EU of a normal LapPack. It can be charged or discharged in an MFE or an MFSU. In addition, it can also be crafted into an Ultimate Lappack. However, this is inefficient, as you can also craft it using a normal LapPack.
