# Fund Subaccounts on Mobile | Internal Transfers & Deposits
Subaccounts can be funded internally from your main account or other subaccounts, or they can be funded externally by performing a crypto deposit from an external wallet.
## Internal Fund Transfers
### Internal Transfers are Free of Charge
No transaction fees will be levied on the following types of internal fund transfers:
| Source | Destination |
| ------------------------------------ | ------------------------------------ |
| Your main account | A subaccount under your main account |
| A subaccount under your main account | Your main account |
| A subaccount under your main account | A subaccount under your main account |
Transferring funds between a main account and its subaccounts does not touch the blockchain, so these transactions are free of charge and virtually instantaneous. However, it should be noted that moving funds out of an account will affect the health of the account. Please move funds carefully to prevent any [unexpected liquidation](https://support.power.trade/trading/margin-and-liquidation/account-health-and-liquidation) by our risk engine.
### Performing an Internal Transfer
To begin, navigate to the **Account Management** screen by tapping on the *Manage Accounts* button on the *Your Accounts* menu.
Select the appropriate subaccount from the dropdown menu and tap on the **Transfer** button.
This will take you to the Transfer Funds screen. Specify the **asset type,** the **Source Account** and **Destination Account** for the internal transfer, and the numerical **amount** to be transferred. Tap on the **Transfer Funds** button to confirm the transfer once you have verified all the information.
## Deposits from External Wallets
### External Deposits Incur Network Fees
Funds can be deposited directly into a subaccount from an external source. PowerTrade does not levy fees on external deposits, but network fees may apply.
### Performing an External Deposit
To begin, navigate to the **Account Management** screen by tapping on the *Manage Accounts* button on the *Your Accounts* menu.
Select the appropriate subaccount from the dropdown menu and tap on the **Deposit** button.
This will bring up the Deposit screen. You can also tap on the QR code icon to reveal your wallet's address in QR code form.
**Important Note:** Be sure to only transfer the correct type of currency into the selected wallet. **Transferring the wrong type of cryptocurrency may render it unrecoverable!**
