I sent a small amount of BTC between my two Electrum wallets. After almost 12 hours the transactions status is still Unconfirmed in both wallets.
The importance of adjusting transaction fees with mempol is to ensure that there are no delays in transactions.
The problem of unconfirmed transactions that you made from wallet A to wallet B using the Electrum wallet has been answered and the answer is that the transaction fees are very low, even below the mempol low priority transaction fees.
Carrying out small transactions with a calculated fee greater than the amount of Bitcoin you will transfer, my advice is not to do it.
If you still have to do it out of necessity, other solutions can be found outside of this.
