You basically wear it, when charged, like you would a chestplate or jetpack. It then powers your chargeable tools until it runs out of energy. Then, simply recharge the batpack and put it on again. In the case of a server which allows raid and PvP, wearing any form of portable energy that takes up armour space has pros and cons. The main upside, being, that you can portably charge your weapons and tools(A LapPack is preferred in this type of server as it has a longer charge). The main con, being, it takes up space which could be going to that protective Nano chestplate you just made.
