Short answer: You do not manually activate rented Energy on trxPay.io. Once it is available at the sending address, TRON uses the available resources when that address sends USDT TRC20.

For the full explanation, read Why Does Sending USDT on TRON Cost TRX?. This page focuses on the specific situation below.

Confirm delivery before the transfer

Paying for the package is not the same as receiving it. Check the actual payer’s current Energy and the wallet’s estimate, then transfer within one hour of arrival.

Use the right account inside your wallet

A wallet app can contain several addresses. Paying from one and sending USDT from another does not make the first address’s resources available to the second. Compare the addresses, not just the app name.

Do not pay an activation charge

The site does not require a second payment or USDT approval to turn Energy on. If the transfer still burns TRX, inspect the receipt for an Energy shortfall, Bandwidth charge, or other issue rather than looking for a missing switch.

Frequently asked questions

Can I rent after sending and recover the earlier fee?

No. Adding resources later does not change a transaction that has already executed.

Does available Energy guarantee that the transfer will succeed?

No. The amount, address, execution limits, and other transaction conditions still need to be valid.

Check Energy and balances

Look up the public address you need to check. No private key, seed phrase, or wallet approval is required.
