Response of the brand
Hi, thanks for taking the time to review our Onpower 310 Power Bank. I'm sorry to hear you had a negative experience of this product. I would invite you to return to your nearest store where they should be able to find a solution for you.
Thanks you for sharing your feedback, it is very valuable in helping us to improve the reliability and functionality of our products, and it will be passed on to the product developers.
