To give you a practical example of how much energy that is... an ICD (Internal Cardiac Defibrillator) uses around 35J (1000 times less energy) to shock a heart, and patients complain that it "feels like being kicked in the chest by a horse". Of course, that shock probably saved their lives, so it's a pretty mild complaint
Look at the pneumatics section of the rule book. Between R78, R85 and R86 I personally don't see how having off-board storage to help charge your on-board tanks is legal. If you are seriously considering this route, please ask on the Q&A so your inspectors have some guidance from the GDC before you show up at the competition!
Also, please note that the rules (R79) specify that all compressed air comes from "one and only one" compressor, with the provided specs for the compressor. Do NOT bring a second robot compressor with the intent of using one to pre-charge and a different one for use during the match. Do NOT bring a normal shop compressor at all. The current those things pull is generally not supported in the pits, and you will most likely be asked to remove it from the venue.
