# Extend Orders

Extend lets you get more out of Energy you've already rented or are about to rent. Use it to:

* Maximize the amount of Energy a target address can receive.
* Prolong the duration of an active block of Energy without risking reclamation.
* Buy more Energy multiple times from the same delegate address.

TronSave offers two ways to do this:

| Method                                         | What it does                                                                |
| ---------------------------------------------- | --------------------------------------------------------------------------- |
| [Quick Extend](/guides/extend/quick-extend.md) | Fast top-up that extends an active Energy block in a few steps.             |
| [Advanced Extend](/guides/extend/advance.md)   | Fine-grained control for repeated purchases from the same delegate address. |

Both methods build on the standard rental flow. If you haven't rented Energy yet, start with \[How to buy Energy & Bandwidth]\(../buy/README.md).
