* ''LightNovel/TheFamiliarOfZero'': A familiar with the Lifdrasir runes can transfer their energy to their Master to power up their spells. Unfortunately, each transfer is a CastFromLifespan, so the familiar gets closer to death each time.

** ''Literature/HeraldsOfValdemar'': Both magic users and [[PsychicPowers Gifted individuals]] can link up, pooling their LifeEnergy to either accomplish something beyond the strength of one person or just to lighten the load. BloodMagic (when performed by voluntary sacrifice) also qualifies.
** ''Literature/TalesOfTheFiveHundredKingdoms'': Individuals with a lot of magic gathered around them (usually because the Tradition is trying to steer them around) can voluntarily donate that magic to a Godmother, white witch, etc. Evil Sorceresses and the like don't bother with consent; they just take it.

* ''LightNovel/SoICantPlayH'': Ryosuke's contract [[{{Shinigami}} with Lisara]] depends on it. Since he derives his power from eroticism, he constantly [[DeusSexMachina fantasizes about sexual acts and euphemisms]], so he can readily transfer large quantities of his power to Lisara, when her flame magic begins to run out.

* In ''LightNovel/LogHorizon'', protagonist Shiroe is an Enchanter, a class [[SupportPartyMember focused exclusively on support]], and his playstyle makes heavy use of abilities which reallocate {{Mana}} between party members as needed.

* A healing device featured in a first-season episode of ''Series/{{Babylon 5}}'' worked this way. Its original purpose was as an execution device, transferring the life-force of the condemned to heal injuries and illnesses.
* ''Series/BuffyTheVampireSlayer'': At the end of "Same Time, Same Place", an injured Willow is meditating in order to heal herself but is too weak to complete the spell. Buffy offers her Slayer strength to Willow and meditates with her, restoring both Willow's body and their friendship.

* At one point in Creator/MercedesLackey's ''Elizabethan'' series, Rhoslyn has returned Underhill (translation: to the elven realms) because she's drained herself working in the mortal world. Her mother transfers energy from herself into Rhoslyn to restore her.

** ''Film/GodzillaKingOfTheMonsters2019'': In the FinalBattle, both Godzilla and Mothra are critically injured in the fight against King Ghidorah. With what little remaining strength she has, Mothra lunges at Ghidorah, who vaporizes her with his Gravity Beams. Mothra's life energy rains down on Godzilla's body, which activates [[SuperMode a a superheated burning form]] that utterly annihilates Ghidorah.

* In ''WesternAnimation/XMen'', after Jean Grey is purged of ComicBook/{{the Dark Phoenix|Saga}}, the team is told that [[EquivalentExchange one of them must give up their own life in order for her to live]].

** After beating Frieza, Goku gives him enough energy to get off the exploding planet the battle took place on. Frieza tried to use it to keep fighting instead, but Goku gave him a chance.

* Goofy in ''VideoGame/KingdomHeartsI'' can learn MP Gift to restore a fellow party member's MP using his own. Given that he's a MagicallyIneptFighter, this will be the only thing he uses MP for.

* ''Franchise/DragonBall'':
** Occurs a few times in ''Anime/DragonBallZ''. Goku's CombinedEnergyAttack, the Spirit Bomb, is the most notable example; at one point Goku even transfers the entire attack's energy to Krillin when he's too injured to throw it himself.
** After beating Frieza, Goku gives him enough energy to get off the exploding planet the battle took place on. Frieza tried to use it to keep fighting instead, but Goku gave him a chance.
** ''Anime/DragonBallGT'' features Goku's Super Saiyan allies ([[MyFriendsAndZoidberg and Pan]]) restoring him to full strength by standing around him for a few minutes and letting him absorb the energy released by their {{Battle Aura}}s. A near-identical process was used in ''Anime/DragonBallSuper'' (and its predecessor ''Anime/DragonBallZBattleOfGods''), to grant Goku access to the Super Saiyan God transformation.
* In ''Franchise/MagicalGirlLyricalNanoha'', mages can transfer {{Mana}} between each other and their [[EmpathicWeapon Devices]] with the Divide Energy spell.

* ''Anime/StreetFighterIIV'': In their showdown with Bison, Ryu gives Ken a portion of his {{ki|Manipulation}}, allowing him to stand long enough to launch one last attack before collapsing.

* ''LightNovel/SoICantPlayH'': Ryosuke's contract [[{{Shinigami}} with Lisara]] depends on it.

* Marvel Comics: Superheroes ComicBook/CloakAndDagger do this all the time. Cloak has darkness powers that he has to feed with energy in order to survive. Dagger produces daggers of light and has to periodically emit them to keep from losing control. They have a symbiotic relationship with Dagger feeding Cloak her excess energy.

* At one point in Creator/MercedesLackey's Elizabethan series, Rhoslyn has returned Underhill (translation: to the elven realms) because she's drained herself working in the mortal world. Her mother transfers energy from herself into Rhoslyn to restore her.

* This is done frequently in the ''Literature/InheritanceCycle'', as the link between a person and a dragon allows for free transfer of energy between the two. This is often used to cast spells more powerful than the person could handle, or to give someone more energy when they become exhausted.

* ''Literature/TheKingstonCycle'' by C.L. Polk: The Invisibles perform WeatherManipulation on a continent-wide scale by funneling all their power into a single elected Voice, who directs and shapes the magic.
* ''Literature/TheBlackMagicianTrilogy'': Mages can voluntarily transfer {{Mana}} between themselves, or use BlackMagic to claim it by force. In the climax, Sonea defeats an enemy Black Mage in a high-powered WizardDuel thanks to [[spoiler:Akkarin [[HeroicSacrifice giving her]] his LifeEnergy as well as his magic.]]
* ''Literature/TheScholomance'': Wizards can transfer their {{mana}} to each other voluntarily; [[MagicalSociety enclavers]] use handheld "power sharers" to pool and distribute their spare mana. When Orion thinks El is having a HeroicRROD, he gives her a solid year's worth without warning, forcing her to burn off the excess with some quick magic.

* ''Series/{{Tracker}}'': Cole essentially does this to Mel in the pilot, reviving her with a burst of energy after she's zapped by Zin. There's a reversal much later in the series, after it's discovered that Mel is a hybrid. She powered up Cole to restore his powers after one of Zin's {{Mooks}} hit him with a laser and rendered him unable to use his alien powers.

* ''Series/BuffyTheVampireSlayer'': At the end of "Same Time, Same Place", an injured Willow is meditating in order to heal herself but is too weak to complete the spell. Buffy offers her Slayer strength to Willow and meditates with her, restoring both Willow's body and their friendship.

* ''TabletopGame/MetamorphosisAlpha'', Dragon magazine #6 article "An Alternate Beginning Sequence For Metamorphosis: Alpha". One of the new mutations was Resurrection Talent, which allowed the mutant to bring a dead character back to life by [[CastFromHitPoints giving them some of the mutant's Hit Points]]. The mutant could heal back the lost hit points normally.

* ''TabletopGame/{{Shadowrun}}'' supplement ''The Grimoire''. Metahumans receive Good Karma (a form of ExperiencePoints) and can donate it to free spirits. The spirits turn the Good Karma into Spirit Energy and use it to increase their Force, so they accept it as a form of payment.

* The eponymous ''Videogame/SuperMetroid'' displays the ability to transfer energy [[EnergyAbsorption it has absorbed]] to Samus in order to heal her.

* ''VideoGame/WarcraftIII'': The Siphon Mana ability drains mana from enemies, but can be used to give it to an ally. The Spirit Touch is a much slower multi-unit spell.
* In ''VideoGame/BreathOfFireIII'' and ''IV'', the Transfer skill transfers [[{{Mana}} MP]] from one character to another. Oddly, it's possible to reduce the MP cost of this skill to zero, effectively turning it into mana from nowhere.
* Goofy in ''VideoGame/KingdomHeartsI'' can learn MP Gift to restore a fellow party member's MP using his own. Given that he's a MagicallyIneptFighter, this will be the only thing he uses MP for.

* The "Bequeath" ability in the little-known browser RPG ''Ankhet'' sends a player of one's choice a small amount of "anima", [[AntiPoopSocking the metaphysical energy that fuels one's actions in the game world]].
* ''VideoGame/{{Elsword}}'': Tactical Trooper (one of Chung's classes)' skill Tactical Field is an AreaOfEffect skill that gives MP to himself and allies over its radius, as well as giving them increased defense.

* In ''VideoGame/FireEmblemTheBlazingBlade'', Nils and Ninian could transfer their energy to each other. This is why when you gain control of them, they share the same stats; neither of them are playable at the same time, so they just transfer their energy to each other each time they switch. Note that in the endgame if you get Ninian back, she would have her base stats rather than her current stats; Nils could not transfer her energy to her, and so all of the experience she gained is gone. (This is only visible in multiplayer, for what it's worth.)

* In ''Webcomic/{{Middleways}}'' Joshua has the power of manipulating Amrit, the LifeEnergy that everyone in Middleways needs. Energy donation is one of the applications of that power--he once saved the life of a patrolmate by donating some to him after the guy got hit with an amrit-draining empty zergball.

* In ''WesternAnimation/XMen'', after Jean Grey is purged of ComicBook/{{the Dark Phoenix|Saga}}, the team is told that [[EquivalentExchange one of them must give up their own life in order for her to live]]. Instead they TakeAThirdOption by having everyone donate a portion of the LifeEnergy required.

* ''WesternAnimation/AdventuresOfTheGalaxyRangers'': One of the "last resort" tactics the team uses is channeling their energy and badge charge through Niko's psionic abilities to create a heavy-duty shield or massive psionic blast. This usually drains the badges and incapacitates Niko afterward, but it does work.

* ''Literature/{{Witchmark}}'' by C.L. Polk: The Invisibles perform WeatherManipulation on a continent-wide scale by funneling all their power into a single elected Voice, who directs and shapes the magic.

* Goofy in ''VideoGame/KingdomHearts'' can learn MP Gift to restore a fellow party member's MP using his own. Given that he's a MagicallyIneptFighter, this will be the only thing he uses MP for.
* Near the beggining of ''VideoGame/GoldenSun: Dark Dawn'', Tyrell is rendered unconcious by a Psyenergy Vortex draining all his energy, and has to be revived by the other characters transfering some of theirs to him.

* ''VideoGame/{{Elsword}}'': Tactical Trooper (one of Chung's classes)' skill Tactical Field is a AreaOfEffect skill that gives MP to himself and allies over its radius, as well as giving them increased defense.

A near-identical process was used in ''Anime/DragonballSuper'' (and its predecessor ''Anime/DragonBallZBattleOfGods''), to grant Goku access to the Super Saiyan God transformation.

* Creator/MarvelComics' ''ComicBook/SecretWars'' has Characters/DoctorDoom wrest the godlike powers away from the Beyonder, then gives Earth's heroes an ultimatum: leave Doom alone, and Doom will leave the heroes alone. Interfere with Doom, and Doom will eradicate the heroes in one fell swoop. Deciding that Doom cannot be trusted, the heroes launch an assault on the Tower of Doom. Doom, not wanting to loose tremendous power that he so recently acquired, donates some to TheDragon Klaw. Klaw is sent to thwart the heroes while Doom attempts to steady his thoughts and keep his awesome power bottled.

* ''Series/{{Tracker}}'': Cole essentially does this to Mel in the pilot, reviving her with a burst of energy after she's zapped by Zin. There's a reversal much later in the series, after it's discovered that Mel is a hybrid. She powered up Cole to restore his powers after one of Zin's {{Mooks}} hit him with a FrickinLaserBeam and rendered him unable to use his alien powers.
