This daily recharge is resetting daily at 5:00 AM Server time. If you have already received the first recharge of the day once, you must wait until it's past 5:00 AM Server and top up then, to be able to claim the next day reward. In order to obtain 4-star Gaara, you must top up at least 50 ingots 5 days in a row. You cannot top up 50 ingots 5 times in the same day,as you will receive the reward only once.
