Thank you for posting the review and letting us know the problem.
Sorry to hear the charger makes noise when charging your devices. Although we work hard to ensure high quality standards through multiple quality checks, we regrettably still come across defective products occasionally.
Please email us at firstname.lastname@example.org with your Amazon order # and review. We are more than happy to assist you with exchange or full refund.
Hope to hear from you soon. Thank you for your kind understanding.
