Power Cubes 
were developed by Dr. Oliver Lynton-Wolfe working for the Niantic Project as devices that store Exotic Matter (XM) in a way that was previously unavailable. They are levelled items that contain concentrated Exotic Matter (XM). When an Agent's XM tank is depleted through deploying, recharging Resonators 
, counterattacks, and other Scanner actions, they can instantly refill some XM reserves by using a Power Cube from the Inventory.
The amount of XM contained in a Power Cube depends on its level. Like Resonators , Ultra Strikes 
, and XMP Bursters 
, a Power Cube obtained through hacking tends to be near the Portal's level or the Agent's Access Level, whichever is lower.
Standard Power Cubes are of "Very Common" rarity. Like other items, they have levels corresponding to the Agent. While the item's listed rarity matches that of Resonators and XMP Bursters , Power Cubes drop considerably less often. Community studies estimate that one Power Cube is dropped every three item rolls. Also available is the Hypercube, which is considerably less common.
XM Capacity[]
Eight levels of Power Cubes exist, each containing XM proportional to its level. As of the 1.93.1 update, Power Cubes can also be recycled for the same value as their capacity.
| Level | XM Capacity/ Recycle Value |
Level | XM Capacity/ Recycle Value | |
|---|---|---|---|---|
| Level 1 | 1 000 XM | Level 5 | 5 000 XM | |
| Level 2 | 2 000 XM | Level 6 | 6 000 XM | |
| Level 3 | 3 000 XM | Level 7 | 7 000 XM | |
| Level 4 | 4 000 XM | Level 8 | 8 000 XM |
Usage[]
Tapping the 'Use' button within the Inventory screen consumes the Power Cube , granting its full XM value to the Agent. Any excess XM beyond the Agent's tank capacity is wasted.
During the 1.93.1 update, the recycle value of Power Cubes increased from 2% of the usage value to 100%. This also allows Agents to 'bulk use/recycle' Power Cubes .
As of 1.94.0, Power Cubes can no longer be used if the Agent's XM tank is full.
Strategy[]
Power Cubes fuel extends Ingress sessions, sustaining intense play with powerful items for hours. Any Agent intent on deploying hundreds of Resonators , destroying dozens of shielded Portals, or recharging a wide area in one trip must manage their Power Cubes efficiently, or risk running out of XM. All items are worthless without the XM to activate them.
Power Cubes are particularly crucial for recharging Portals, an extremely XM-intensive action. A single Level 8 Portal could easily require five Level 8 Power Cubes to recharge, and the cluster could contain 20 or more Portals.
Defending a Portal under continuous assault requires a massive cache of Power Cubes . An Agent fending opponents off a key Portal could consume 20 or more Power Cubes per minute.
Attacking also requires a supply of Power Cubes . The high XM cost of powerful XMP Bursters , combined with strong counterattacks from the Portals, rapidly saps the attacker's XM. A steady supply of Power Cubes is required to recover and continue the assault.
Because any excess XM is lost, savvy Agents will intentionally deplete their XM reserves by remotely recharging Portals prior to using Power Cubes . This way, the excess XM is returned to the faction's assets instead of wasted.
Hypercube[]
Unlike normal Power Cubes , the Hypercube has a rarity of Very Rare. It has considerably more XM than a standard Power Cube . Instead of replenishing your XM reserves in a single large quantity, the cube instead actively replenishes your XM store until it is depleted. Unlike normal Power Cubes , the Hypercube can be used when your XM tank is full; however, it cannot be used when another Hypercube is being used.
When used, a small bar appears under your XM reserve bar, with the model of the Hypercube next to it. This bar will actively regenerate your XM reserves according to your needs until it is depleted. When the Hypercube reaches 10%, you will hear an audible warning. However, the Hypercube cannot be used as an extension to your XM tank, thus preventing you from performing actions that go beyond how much XM you have. Upon being completely drained, the cube will disappear from your inventory. The amount of XM in a Hypercube is proportional to your level.
Lawson Power Cube[]
The Lawson Power Cube was a sponsored item. It was discontinued in December 2019. Remaining Lawson Power Cubes were converted to Hypercubes.[1]
Its function was the same as the Hypercube. Like the Hypercube, the Lawson Power Cube had a rarity of Very Rare.
As of version 2.38.3, all Lawson Power Cubes have been converted to Hypercubes.
Circle-K Power Cube[]
The Circle-K Power Cube was a sponsored item. It was no longer hackable since May 2018, but remained in Agents' inventories. In December 2019, remaining Circle-K Power Cubes were converted to Hypercubes.[1]
Its function was the same as the Hypercube. Like the Hypercube, the Circle-K Power Cube had a rarity of Very Rare.
As of version 2.38.3, all Circle-K Power Cubes have been converted to Hypercubes.
