Definition: In this task, you're given reviews from Amazon's products. Your task is to generate the Summary of the review.
Input: Truly disappointed in this purchase. The cords will not charge when an item is being used. The lengths are amazing and the quality of the cord seems okay, yet I have yet to have anything charge while being use and without being used it takes 12 - 15 hours to increase 25%.

Do your research, this cord has not charged any item we have while its being used.
