# Power System
Power is required to earn tokens and Loot Crate during gameplay. Each 1 Power represents 10 minutes of active session time.
Power regeneration begins only after acquiring an NFT Computer. To start a session, users select a Computer and press Start.
It is important to ensure you have Power before beginning a session, as no tokens or Loot Crate are earned when Power is at zero.
Power regenerates at a rate of 25% every 6 hours, until it reaches the user’s Power Cap.
The maximum Power a user can hold increases by owning additional Computers. The detailed calculation is outlined in the Power Cap section.
| Computer
No.
| Power | Activity time (min) |
| ---------------------- | ----- | ------------------- |
| 1 | 2 | 20 |
| 3 | 4 | 40 |
| 9 | 9 | 90 |
| 15 | 12 | 120 |
| 30 | 20 | 200 |
Bonus Power (cumulative) for Higher Quality Computers:
* Rare Computer: +1 Power
* Epic Computer: +2 Power
* Legendary Computer: +3 Power
EXAMPLE 1:
1 Rare Computer + 1 Common Computer = 3 Total Power (2 Base Power + 1 Bonus)
EXAMPLE 2:
2 Epic Computer + 1 Common Computer = 8 Total Power (4 Base Power + 4 Bonus)
Marketplace Listings and Transfers:
Listing a Computer on the Marketplace results in the loss of Power and Power Cap corresponding to that Digital Computer.
Transferring a Computer between accounts triggers a Cooldown period during which the Digital Computer cannot be used.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://gamebyts.gitbook.io/gamebyts/deep-dive/earning-module/power-system.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
