Power Bracelet

The Power Bracelet is a strength-increasing item that bolsters Link's muscular power to that of a superhuman, or its equivalent in the Zelda universe, a Goron, for the most part. Power Bracelet, as a blanket term, not only caters to the physical ring-like objects Link acquires throughout his travels, but also defines the strength-intensifying gloves and mitts, such as the Golden Gauntlet and the Titan's Mitt, that allow Link to perform at an increased strength level as well. The actual bracelet is more common in the 2D Zelda games but has also made appearances in The Wind Waker; their glove-like counterparts appear vividly in Ocarina of Time and A Link to the Past, respectively.

Power Bracelet(s)
The Power Bracelet is not only the most rudimentary of the strength-inducing items, as it appeared first in the original The Legend of Zelda, but is also the most popular of the two, the other being its identical counterpart, the Power Glove. Since its first appearance in The Legend of Zelda, the Power Bracelet is a gold ring-like object (save for its burgundy Link's Awakening incarnation) that is obtained through significant plot events, whether it is given to help in  ridding the Dodongo's Cavern of baddies in Ocarina  of Time (this version is called the Goron's Bracelet), required to access  the Earth Temple in The Wind  Waker, or simply needed to uplift small boulders in titles such as The Legend of Zelda and The Minish Cap, the latter of which can only be used while Link is Minish-size.

Although they are mostly called Power Bracelets, they very rarely exist in pairs, appearing only as such in The Wind Waker and The Minish Cap. Regardless of the number of bracelets, the effect on Link is the same - he is able to lift otherwise unliftable objects ranging from mere rocks and bookcases in The Legend of Zelda and The Minish Cap to large Stone Heads in The Wind Waker.

Interestingly, the Power Bracelet of Link's Awakening can be upgraded to a Level 2 over the course of Link's journey, enabling him to lift even  heavier objects than before, and the iteration used in Four Swords Adventures is the only incarnation of Power Bracelet that can be used, lost, and regained between levels, as the bracelet only appears in levels that require its specific use. The iteration seen in Oracle of Ages bridges the gap between Power Bracelets and Power Gloves, as the bracelet can be upgraded to the superior glove version before accessing the Ancient Tomb, a dungeon that requires the extra strength provided in the Power Glove to complete.

Power Gloves, Titan's Mitt, and the Gauntlets
The Power Glove is a minor twist on the Power Bracelet, although the increased strength effect is practically identical to that of its ring-like counterpart. Appearing originally in The Adventure of Link as the Handy Glove, its most primordial function operates through Link's sword: it increases the strength of the sword itself, so much so that it can slice and crush blocks. Over subsequent titles, beginning with A Link to the Past and on through Ocarina of Time, such emphasis is placed instead on Link's physical strength, stemming from his hands and his ability to lift objects in comparison to slicing them, when speaking of the Power Glove. The glove of A Link to the Past can even be upgraded from its original form to the Titan's Mitt, a superior, golden glove that can lift heavier, dark boulders; the obtainment the Titan's Mitt further spurs Link towards achieving the Tempered Sword, as well.

The Power Glove truly did not achieve its current popularity until it broke into the third dimension, in the forms of the Silver and Golden Gauntlets seen exclusively in Ocarina of Time. These metallic gloves are the behemoths of the strength-inducing objects, as they retain the ability to lift monoliths of extreme size, often many times the height of Link, just with the flick of the wrist. The Silver Gauntlets are found in the Spirit Temple while the Golden Gauntlets are found in Ganon's Castle. Although these gauntlets could only be used in Link's adult era, they play a huge role in the game's plot, alleviating blocked passageways, revealing secret Great Fairy Fountains, and the Golden Gauntlets even aid in the completion of both the Light and Fire rooms in Ganon's Castle. Not only can the Golden Gauntlets lift towering black blocks in comparison to the lesser Silver version, they replace the Silver Gauntlets and the Goron's Bracelet (only usable by the younger Link) in Link's inventory upon its obtainment.

Magic Bracelets
In the Zelda animated series, Magic Bracelets function and look much like in the original The Legend of Zelda. The bracelets appear in the episode "That Sinking Feeling" and give its wearer one minute of super strength. Link obtains the Magic Bracelets after he defeats a Darknut, and he uses them later on in the episode to break free from the chains that Ganon tied around him. After breaking free, Link lifts Ganon and throws him far away, eventually defeating him.

Magic Glove
In the Legend of Zelda comic, Link uses the Handy Glove from The Adventure of Link in a fight against Bagu, although it is known as the Magic Glove here. When Link finds out that Bagu stole a fragment of the Triforce of Wisdom, Link grabs the Handy Glove and proceeds to hunt down Bagu. He spots Bagu coming back towards the castle, and charges him before the two engage in combat. Link then uses his glove and is able to heave Bagu into the air and throw him down, forcing Bagu to reveal why he took the sacred relic. When he confesses that he gave the Triforce fragment to Ganon because he's holding Bagu's pet frogs for ransom, Link reluctantly allows Bagu to use his Magic Glove so that he can defeat the Prince of Darkness and retrieve his frogs.

Trivia

 * Preceding their equivalents in Ocarina of Time, the Power Glove and Titan's Mitt of A Link to the Past subtly alter Link's sprite so that his hands are armored and no longer flesh-colored. However, this detail was inexplicably removed in the Game Boy Advance port.
 * In Master Quest, the Golden Gauntlets have relocated from the Shadow Room to the Spirit Room.
 * Curiously, the Power Bracelets don't seem to affect Link's strength at normal size in The Minish Cap.
 * The power glove may be a reference to the power glove controller for the NES.
 * The "Wristband", an item from For the Frog the Bell Tolls, seem to have adopted the purpose of pushing heavy items from the Power Bracelet. The sprite for the bracelets in The Minish Cap and The Wind Waker are very similar to the sprite of the Wristband. [[File:For_The_Frog_The_Bell_Tolls_-_Wristband.png‎]]. There is also an upgraded version of this item known as the "Work Glove", which allows Prince Hans to push the gigantic boulders he encounters on his journey.
