Personal Force reservoir

Several Force powers had different demands in concentration and endurance than others, on behalf of the Force user. Continuous or excessive usage of the powers would have resulted in "Force fatigue" with several unwanted symptoms, both physical and mental. It is possible the number of Midi-chlorians being possessed had an impact on the scale of one's reservoir. However, even a being with formidable Force potential could find their Force Powers countered by someone more skilled, or even be defeated by someone with better tactics as when Darth Vader lost to Obi-Wan on Mustafar after failing to overcome him with a Force Push.

Count Dooku experienced some waning and waxing of his strength with the Force during the duel on the Invisible Hand. In this case, Dooku's over-reliance on the dark side led to "Force exhaustion," temporarily shutting down his natural Force senses. In several instances, this fatigue was suggested to have been heavily linked to Dooku's state of mind, with his strength being restored by a moment's introspection.

The excessive use of the battle meditation Force technique by Darth Caedus during the Second Battle of Fondor rendered him "thin-stretched" and unable to move or think clearly for a while, clearly demonstrating the limitations of Force usage. It was fairly likely that these limitations referred much to mental limitations and also the inability of the body to withstand continual use of external energies. By going into a state of Oneness, a Force User could temporally access and unleash an amount of power far beyond their normal limits, but this state was very hard to achieve and usually ravaged the body as too much Light or Dark energy killed the user's cells.

The Corellian Jedi apprentice Corran Horn referred to his personal Force reservoir, during his training at the Jedi Praxeum.

The concept of Force repository appears in Lucasarts games and is a game mechanic. By using Force powers, the pool wears out, and replenishes slowly with time/rest. Its role in games is to simulate the natural limitations (such as fatigue, concentration, experience) of a user, while its gameplay value is the same as the 'mana pool' of fantasy games; such measures prohibit the player using all of his powers every moment and therefore urges him/her to strategically choose the best time for each action rather than using them recklessly.

In the wider universe it is not often explicitly mentioned that the Jedi have a finite (though replenishing) repository of powers--and someone may regain expended energy by rest and meditation.

However the exact mechanism of these limitations is unknown and almost certainly not so mathematically precise as the 'Force mana' of the video games.

In most games the Force repository replenishes itself with time/rest. In some games such as the Super Star Wars trilogy for Super Nintendo, and Star Wars: Episode I Obi-Wan's Adventures, the Force repository is replenished only by taking some bonus found in the environment (a potion-like bonus in the former).

In the non-canon Soulcalibur IV, the three Star Wars characters' Force feature is called Force Meter.
