The '''power drain''' is a combat support device designed and developed by the [[Covenant]] for its infantry forces. The equipment has several colloquial nicknames among [[United Nations Space Command]] personnel, including "'''Draino'''" and "'''Drainer'''".{{Ref/Reuse|Enc09}}{{Ref/Book|Id=EVG|EVG|Page=47}}

==Overview==
===Design details===
The power drain is a roughly spherical device massing {{Convert|11.2|lb|kg|disp=flip|sp=us}}. When activated, the device emits a blue [[electromagnetic pulse]] field for around 6.5 seconds, after which the device self-destructs in a small explosion. The EMP is used to short out the electrical systems of any equipment caught within range, including [[energy shielding]] and light vehicles. During its activation, two cylindrical emitters are extruded from the sides of the sphere.{{Ref/Reuse|Enc09}}{{Ref/Site|Id=BNet|URL=http://halo.bungie.net/content.aspx?link=h3betaEquipment|Site=Bungie.net|Page=Halo 3 Beta: Equipment|D=14|M=10|Y=2014}}

The power drain has a visual resemblance to the [[flare]] and [[radar jammer]] equipment also developed by the Covenant, save for its blue colouration. The Flare, developed by the [[Jiralhanae]], was based on the same technology as the power drain and radar jammer.{{Ref/Book|Enc22|Page=341}}

===Usage===
The power drain is a piece of infantry support equipment developed by the Covenant, and was heavily employed by the [[Jiralhanae]] loyalist forces of the [[Prophet of Truth]] during the final weeks of the [[Human-Covenant War]].{{Ref/Reuse|EVG}}{{Ref/Game|Id=H3|H3|Power Drain in-game equipment}}{{Ref/Game|Id=H3ODST|H3ODST|Power Drain in-game equipment}} Despite their origin, [[human]] forces were more than willing to make use of captured enemy power drains during the war.{{Ref/Reuse|EVG}}

==Gameplay==
{{Linkbox|gameplay=yes}}
===''Halo 3'' and ''Halo 3: ODST''===
The power drain is one of several pieces of deployable [[equipment]] featured in ''[[Halo 3]]''. When thrown, the power drain takes 0.5 seconds to activate, and subsequently lasts 6.5 seconds, equaling a total of [[Seven|7]] seconds. The effects of the power drain pass through walls and floors, so simply fleeing to the bottom floor of a structure after an enemy activates one will still strip one's shields if one passes through the field. This is most noticeable on maps like [[Guardian (Level)|Guardian]].{{Ref/Reuse|H3}}

The power drain can be used in a glitch called [[Equipment jumping]] by moving against a wall, jumping, and then at highest point of the jump deploying the power drain. This allows a player to jump off of it in mid-air. This is a great tactic for reaching high areas of a map, such as the second level of the tower on [[The Pit]]. This can also be done with the radar jammer and flare. The power drain variation of the glitch is commonly claimed to only be able to be performed as an [[Sangheili|Elite]]. This is not the case, but it is exceedingly difficult to do as a Spartan in the [[Xbox 360]] version of ''[[Halo 3]]''; thus, only a few instances of it have been documented, most notably in the U.S. Army Vehicle Training: UNSC Halo 3 Sniper School 4 video. It appears to be easier to accomplish while playing as a Spartan in the ''Halo 3'' portion of ''[[Halo: The Master Chief Collection]]''.{{Ref/Reuse|H3}}

In ''[[Halo 3: ODST]]'', the power drain performs as it did in ''Halo 3'' though cannot be used by the player. It is only used by Brute enemies; when the player is in the radius of a power drain, their health will drain in addition to their shields.{{Ref/Reuse|H3ODST}}
