# Power

> How a Squeek's level sets its maximum power, what active power is, when new power starts, and when a Squeek can merge again.

Web version: https://docs.squeekchain.com/squeeks/power/

## TL;DR

- A Squeek's level sets its maximum power. Active power is the part that earns.
- New power starts earning in the round after a mint or merge.
- After a mint or merge, a Squeek waits out a cooldown before it can merge again.

## Levels and maximum power

Each level sets a Squeek's maximum power. Merging two Squeeks of the same level creates one Squeek a level higher, and each level has more than twice the power of the one below.

Each merge starts a [cooldown](https://docs.squeekchain.com/squeeks/power.md#when-can-you-merge-again) before the Squeek can merge again.

## Active power

Active power is the part of a Squeek's maximum power that earns. [Staking](https://docs.squeekchain.com/rewards/staking.md) explains how it's set.

## When does new power start earning?

A new Squeek starts earning in the round after it's minted. After a merge, the survivor keeps earning with both Squeeks' combined power until the next round, then switches to its new level's power. Transferring a Squeek doesn't change its power.

## When can you merge again?

A cooldown starts when a Squeek is minted or merged, and it's counted in completed Squeek blocks. Higher levels wait longer. The cooldown stays with the Squeek if it's transferred, and a merge checks it against the live block height, so it never waits for a checkpoint.
